Changelog
What's New
All the latest updates, features, and fixes.
Reliable Trial Sign-In and Steadier Account Checks
- Fixed sign-in failing for new users with a "your licence could not be set up" error, so trials now start reliably.
- Trials now get the same offline grace period that paid subscriptions already had, so a dropped connection doesn't lock you out.
- Fixed a server-side problem that could make sign-in and account checks fail for stretches of the day.
Vectors Settings Restored, a Clearer Sign-In Screen, and Safer Links
- Fixed a crash when clicking "+ Create Vector" in Settings, and restored the full Vectors tab — vector and smart vector cards, the icon picker, and drag-to-reorder.
- Fixed the launch screen getting stuck on "Connecting…" after a sign-in was refused; the sign-in screen and its retry button are visible again instead of sitting behind the spinner.
- Fixed AI error messages being able to include your API key when a request failed.
- Hardened the in-app checkout and billing portal so they only ever open genuine Stripe pages.
- Conferencing sign-in links for Zoom, Google Meet, and others are now validated before they open.
- Fixed an empty-state message in the Connections list rendering without a visible frame.
A Launch Crash Fixed, and Tidier Settings Tabs
- Fixed the app crashing on launch, and search failing, after a change to how the message list reads data from the server.
- Fixed the Settings > Accounts sub-tab labels, including "Conferencing", getting clipped mid-word instead of shrinking to fit.
- Fixed the Calendars and Tasks settings sub-tabs showing their sections in the wrong order.
- Fixed the Accounts list opening the wrong account when a click started on one row and ended on another.
- Fixed the launch screen's logo keeping its old color when you switched between light and dark mode.
- Fixed the focus ring vanishing from toolbar buttons, such as in Compose, when a focused button redrew.
A Smoother First Sign-In
- Fixed signing in sometimes leaving you behind the subscription screen right after a successful sign-in, before your trial or license had finished activating.
- Fixed a new install briefly showing the subscription lock screen before you'd had a chance to sign in and start your trial.
- Fixed a vague error when a trial's one-device limit was reached — the sign-in screen now explains why, with a button to try again.
A Rebuilt Accounts Settings, Working Service Tabs, and Chat Reconnect Fixes
- Accounts settings is now a single scrollable list of every connected account — mail, chat, and calendar — each with a status dot, drag-to-reorder, and full keyboard navigation.
- Click an account to open a detail view with its sync health, one-click fixes for problems like re-authorizing Gmail or reconnecting Slack, and separate Export, Delete Server Data, and Remove actions.
- Calendars, Tasks, Chat, and Conferencing settings are no longer placeholders — each has working controls for connecting, disconnecting, and configuring the service.
- Fixed reconnecting a chat workspace sometimes erasing its cached conversations, or losing the workspace entirely if the reconnect failed partway through.
- Fixed the Reconnect button for Zoom doing nothing when clicked.
- Fixed Cmd+4 through Cmd+8 opening the wrong Settings tab after the sidebar was reordered, and gave Learned Rules and Shortcuts their own numbers.
- Paywall screens no longer lead with Subscribe for problems a purchase can't fix, such as a revoked license — they offer Contact Support or Recover License instead.
Settings Reorganized, a Steadier Lock Screen, and Honest Paywall Copy
- Settings is reorganized: Calendar and Combined Inbox moved out of the sidebar into new sub-tabs under Accounts, cutting the sidebar to nine entries.
- Fixed several ways the subscription lock screen could be dismissed or fall out of sync — a sign-in prompt no longer tears it down, menu items stay disabled while locked, a lapsed license locks the app right away, and the app no longer flashes unlocked content at launch.
- Fixed connecting a mailbox to an identity that already had a linked chat workspace, which could delete that workspace's synced conversations or leave a duplicate account behind.
- Fixed Settings dropdown menus flashing when you picked an option, sizing raggedly, and opening panels that could overlap their own label.
- Suspended-account screens now lead with Manage Account instead of another purchase, and their Contact Support link works.
- Corrected inaccurate paywall copy, including a false two-device limit.
- Fixed Settings toggles briefly showing the wrong on/off state after being flipped, and the Settings sidebar occasionally losing its selection highlight.
Faster Account Switching, and a Refreshed Purchase Screen
- Fixed Cmd+1–Cmd+0 account switching sometimes leaving the inbox permanently empty until new mail happened to arrive.
- Fixed a signed-out or revoked account leaving you on a stale inbox with no prompt — you now get the sign-in screen every time, and stay on that account instead of being dropped.
- Fixed a combined inbox sometimes showing mail from every account instead of only the accounts in the selected group.
- Switching accounts and folders by keyboard is faster, removing a stall of up to a third of a second.
- Refreshed the purchase and upgrade screens to match the rest of the app, with a centered card, corrected colors and pricing layout, and a Recover License link.
- Fixed the purchase card's content getting pushed outside its frame, and a button on some license-problem screens that did nothing when clicked.
- Signing an account out now clears its learned rules and correction history instead of leaving them active for the rest of the session.
Steadier Launch, Reliable License Checks, and a Finished Paywall
- Fixed launch sometimes failing to open the remembered account when its saved sign-in had been revoked.
- Fixed the inbox briefly freezing while mail finished sorting, and a rare case where an old sorting decision could reappear after a relaunch.
- Fixed Restore License and related checks occasionally failing with "Invalid or expired code".
- The subscription paywall now appears for every locked license state, and properly blocks menu commands and keyboard shortcuts while it's up.
- Fixed the quick-task keyboard shortcut not opening the Tasks tab unless Tasks was already open.
- Fixed Settings occasionally showing a stray license key next to "No active subscription".
In-App Subscriptions, Working Command Palette Rows, and Attachment Downloads
- Subscribe from inside Hyperdrive: see current pricing with a monthly/annual toggle, pay in a secure window, and manage billing from Settings > Subscription.
- A lapsed trial or license now shows a paywall with steps to recover an existing license by email.
- Fixed dozens of command palette rows, menu items, and keyboard shortcuts that silently did nothing — Go to Inbox, jumping to any sidebar mailbox or label, Move to Vector, Move to Inbox from Trash, Star/Unstar, Report Spam, and switching calendar views with D, W, and M.
- Added a View → Sort menu that shows the active sort order, and fixed the palette's "Sort by…" and "Filter by…" rows, along with the No Reply and New Messages filters.
- Fixed Download All Attachments — it now saves every attachment from a thread into a folder you choose, renaming duplicates so nothing gets overwritten.
- Added Reclassify Mail in Vector settings, with a confirmation dialog offering to redo AI sorting or reset everything to defaults.
- AI settings now fetches the current model list from Hyperdrive's servers, so new models appear without an app update, and remembers the last list when you're offline.
- Fixed a crash when opening Settings > Signatures, and fixed the scheduling-link editor discarding a custom duration, buffer, or timezone.
A Sync Hang Fixed, and Cleaner Chat Replies
- Fixed the app hanging when you pressed Sync All, because the sync work could end up running in the foreground instead of the background.
- Fixed the formatting toolbar showing mail-only buttons, like fonts and colors, when replying to a chat message.
- Fixed a brief flash of an oversized rectangle when opening the command palette and some other pickers.
Thread Summaries in the Thread, List Actions, and Slack Fixes
- The AI thread summary now lives in the thread itself, right above the message, and collapses out of the way.
- Reply, Reply All, Forward, and Delete Draft now work directly from the thread list, without opening the thread first.
- A new, consistent icon set throughout the app.
- Fixed Slack conversations rendering as anonymous, unlabeled messages — sender names, reply counts, and presence dots now show correctly.
- Fixed several chat-reply problems: outgoing Slack messages now keep their formatting, post from the right account, and queue for retry when you're offline.
- Fixed "Move to… → All from this sender's domain" freezing the app for several seconds on large mailboxes.
- Fixed a crash when opening a thread while its AI summary was still loading, and Archive doing nothing while an inline reply card was open.
Calendar Unenrollment, a Line-Height Setting, and Blank-Body Fixes
- The eye toggle on a calendar row in Settings > Accounts now fully unenrolls that calendar, removing it from the sidebar and from event sync, instead of only hiding it.
- Added an email line-height setting in Settings > General.
- Fixed some email bodies rendering blank except for a "…" toggle, caused by quoted history in Outlook-formatted messages.
- Fixed the account storage line showing an impossible count, such as more saved conversations than the mailbox actually has.
- Fixed Sync All skipping archived mail that looked already up to date.
- Improved detection of sales and marketing email by measuring a message's real content and ignoring quoted replies and boilerplate.
Account Colors Everywhere, and a Tasks Crash Fixed
- Fixed a custom account color from Settings > Accounts not showing up everywhere — task dots, the account switcher, sidebar headers, and thread and search rows now all pick it up immediately.
- Fixed a crash when opening the Tasks panel with a task belonging to a removed account.
Create Labels from the Picker, Subject Reminders, and Sidebar Counts
- Creating a label directly from the label picker now works — the label is created on the server and survives restarts and re-syncs, instead of showing a "not available yet" error.
- Added a confirmation dialog, with a suggested subject, when you send a message with no subject.
- Added a Settings option to show sidebar label and tab counts as unread or total messages.
- Fixed Tab and arrow-key navigation not working in the date picker when scheduling a send or a reminder from Compose.
- Fixed banner keyboard shortcuts firing when no banner was on screen.
- Redesigned the milestone celebration message to match the app's standard notice banner.
Faster Launch, Reliable Escape Keys, and a Fixed Preview Crash
- Fixed inbox classification stalling the launch screen for a long stretch when your network connection is slow or drops out.
- Fixed the launch progress counter sitting at zero for the whole scan, then jumping straight to done.
- Fixed Escape not closing the AI rewrite panel, the link editor, and a few other dialogs that previously ignored the key.
- Fixed a crash that could happen when reopening an attachment preview.
Safer Attachments, Smarter Model Downloads, and Full-Screen Composer Shortcuts
- Attachments are now checked before you can open them, so a malicious file triggers the normal security prompt instead of running silently.
- The AI model Hyperdrive downloads during onboarding now sizes itself to your Mac's available memory instead of ignoring it.
- Fixed keyboard shortcuts — Send, Send Later, Bold/Italic/Underline, Reply, Delete, and Share — not working while the composer was full screen; only the toolbar buttons worked before.
- Fixed Esc closing the entire composer instead of just dismissing the recipient suggestion list.
- Fixed N and P not moving you between messages in an open thread.
- Fixed undo after a sender sweep sometimes leaving some archived threads un-restored.
- Fixed a sender sweep issue where a specially formatted sender address could archive threads beyond the ones you meant to sweep.
Attachment Actions, Quick Look Previews, and Streamlined Banners
- Click an attachment to open it, or choose Save to send it straight to disk with a standard save panel.
- Preview attachments right from the message with Quick Look, without leaving Hyperdrive.
- Attachments that don't show inline now appear as chips on the message so you can always find and act on them.
- The Unsubscribe and image-blocking banners are now a single compact row, with Trust sender, Trust domain, and other options tucked behind a gear menu.
- Mark Read / Mark Unread in the command palette now always matches the selected thread's actual state, and works from the inbox too.
- Fixed the Quick Look preview panel occasionally freezing at the wrong size or staying hidden when reopened right after closing.
Block an Entire Domain, and a More Honest Sync
- Block an entire domain in one action, from the command palette, the Message menu, or the sender's own block menu. Every message from that domain sweeps away together, and undo reverses the whole thing at once.
- The block and unsubscribe pickers now show how many emails you'd be affected by, and you can type part of a name or domain to filter the list.
- On a fresh account, sync now shows real progress ("142 of 2,474") from the first few seconds instead of sitting on "Warming the onboard models…" for over a minute.
- Fixed pressing T to toggle a message's read state crashing the app.
- Fixed dismissing certain notice banners, including the onboarding tutorial's Skip button, crashing the app.
Block and Unsubscribe Picker Cards, Mailbox-Wide Sender Sweeps, and Self-Correcting Learned Rules
- Press B on a thread to open a Block Sender card, or U to unsubscribe — each offers a plain action, action plus archive this thread, action plus archive everything from that sender, or always do this from now on.
- New Privacy settings let you skip the confirmation card entirely, so unsubscribe or block happens immediately every time.
- "Archive all from sender" now clears every message from that sender out of your inbox, including mail not yet synced to this device, and undo brings all of it back in one step.
- Learned rules that keep getting corrected now retract themselves automatically, and rules that conflict with another category relocate instead of duplicating — either way you'll see a toast, with undo available for relocations.
- Fixed a couple of keyboard shortcuts sometimes triggering the wrong action, including Tab misbehaving in the thread list when a banner was on screen.
Multi-Account Accuracy Across the App and More Reliable Send Confirmation
- Search, Activity, Drafts, the folder sidebar, Scheduled sends, and a contact's recent conversations now cover every account you have visible, not just whichever one happens to be active.
- Compose automatically preselects the correct sending account in the From picker.
- Delivery records for sent messages now stick around well over a year instead of aging out after a week, so a scheduled send that goes out while your laptop is closed for a while no longer gets mistaken for undelivered.
- Fixed the thread list, contact card, calendar day markers, and event RSVP pills not staying accurate when you have more than one account in view.
- Fixed Hyperdrive reporting a scheduled message as failed when it had actually just lost track of whether it sent; it now says it couldn't confirm the send instead, and points you to the saved draft.
- Fixed disconnecting an account leaving its sign-in session active.
Combined Inboxes, Group Management, and View Switching
- Group any of your accounts into a single Combined Inbox. Create, rename, and drag-reorder your groups from a new Combined Inboxes tab in Settings.
- Add or remove accounts from a group right in Settings. A group always keeps at least one member, and you can't add the same account twice.
- Flip between your individual accounts and a combined view with Cmd+`, or jump straight to a specific combined inbox from the command palette.
- Unread counts, contacts, calendar, snippets, reminders, and recipient autocomplete all now reflect every account in a combined view, not just one.
- Sending, filing, and sorting mail in a combined inbox now always credits the right underlying account, and corrections you make to how mail is sorted stay attached correctly even when you're viewing a combined inbox.
Sign-Out, Workspace Cleanup, and Account Security Fixes
- Fixed sign-out leaving some queued actions active, so an archive or a Slack message could still go out after you'd already signed out.
- Fixed sign-out not revoking your Slack authorization along with everything else.
- Fixed removing a Slack workspace leaving its cached messages, threads, and channels behind instead of clearing them completely.
- Fixed account removal finishing even when its data cleanup failed, which could leave orphaned data with no way to reach it again.
- Fixed a security issue where an email address you'd verified with Google could still be claimed by an unrelated trial license.
Practice-Run Composing and an Auto Draft Shortcut
- The practice run now teaches composing, not just triage. After the triage keys, it walks you through drafting a reply, rewriting it, arming a compose reminder, and sending — all in the real composer.
- Auto Draft now has a keyboard shortcut: Cmd+Shift+D.
- Fixed account email addresses being written to the system log, where other apps on your Mac could read them.
Combined Inboxes, Cross-Account Sync, and Reliable Header Parsing
- Combine several accounts into a single named inbox, with a tab for each account inside it. Switch to it from the command palette or with Cmd+1–Cmd+0, and it's exactly where you left it next time you launch.
- Combined inboxes carry across your Macs, the same as the rest of your account list.
- Mail sync, calendar events, and spam learning now cover every account showing in a combined inbox, not just whichever one happened to be active last.
- Fixed archive, trash, star, move, and mute failing and retrying forever on non-Google accounts.
- Fixed a thread losing its AI category when you moved it to another folder.
- Fixed some incoming mail showing a blank sender or subject, and inline images not appearing, due to inconsistent header parsing.
- Fixed unsubscribe sometimes sending from the wrong account.
- Fixed a rare crash on quit.
Account Health Status, Instant Account Switching, and Reply-All by Return
- Settings > Accounts now shows each account's health, flags a sync that's stalled or being repeatedly refused, and offers a one-click fix plus a cancellable Sync All.
- Switching to an account you've already been using is instant now — the account you're viewing always finishes syncing first.
- Press Return inside an open thread to jump straight to Reply All.
- Important notices, like a failed scheduled send, now show as a bold banner you can't miss instead of a quiet pill.
- Fixed a crash when signing out of or switching between accounts.
- Fixed the account-deletion confirmation email going to the wrong address.
Disconnected Account Recovery, Steadier Scheduled Sends, and Sync Fixes
- A disconnected account now shows up greyed out in Settings > Accounts with Reconnect and Remove actions, instead of vanishing with no way back in.
- Send Later dims when it can't reach the scheduling service, so you're not left waiting on a send that has nowhere to go.
- You'll get a notice if a scheduled send ultimately fails and won't be retried, instead of only finding out from the recipient.
- Fixed scheduled sends dropping their attachments when they went out while your Mac was asleep.
- Fixed Combined Inbox turning back on after relaunch when you'd switched it off with a keyboard shortcut or the account switcher.
- Fixed some mail syncs failing outright when Gmail stumbled on part of a batch, instead of keeping what had already downloaded.
- Fixed the unread dot in the thread list overlapping the start of the sender's name.
Keyboard Practice Onboarding, Automatic Reconnect Prompts, and Switch to Account
- Onboarding now includes a hands-on keyboard shortcut practice: work through a live example inbox to get comfortable with Hyperdrive's shortcuts before using them for real.
- When an account needs you to sign back in, Hyperdrive now raises the sign-in panel for you automatically. Choose "Don't Reconnect" to disconnect that account instead, or reconnect it later and it comes back right where it was.
- Switch to another connected account straight from the command palette, once you have more than one account connected.
- The sidebar now shows a clear placeholder instead of a blank line for a folder or account section with nothing in it.
- Fixed Combined Inbox turning itself off every time you launched Hyperdrive.
- Fixed the "Connect Your Account" panel staying on screen after a newly added account finished signing in.
- Fixed malformed email addresses being accepted when composing, replying, or resuming a draft.
Multi-Account Switching, a Sectioned Combined Inbox, and Drag-to-Reorder Accounts
- Switch straight to any account with Cmd+1 through Cmd+0, or cycle through all your accounts and All Inboxes with Cmd+` (Cmd+Shift+` to go back). The account switcher opens as its own floating panel.
- All Inboxes now groups your system folders together up top, then sections your labels by account, each with its own color-coded dot so you can tell at a glance which account a label belongs to.
- Drag account cards in Settings to put them in whatever order you like. New accounts you add land at the end of the list.
- Ten distinct account colors, up from five, so accounts stay easy to tell apart even with a full list.
- Fixed Reply, Reply All, and Forward sometimes sending from the wrong account when a thread involved more than one of your addresses.
- Fixed initial sync getting stuck after a failed attempt instead of retrying automatically.
Combined Inbox Goes Fully Multi-Account
- Combined Inbox now syncs and classifies every connected account at once, instead of only the one you're currently viewing.
- Refresh (Cmd+R) now updates every connected account when Combined Inbox is on.
- If adding, removing, or reauthorizing an account fails, you'll now see a message instead of the action silently failing.
- Fixed threads, folders, and unread counts flashing incomplete or re-sorting while an account was still catching up, in both Combined Inbox and single-account view.
- Fixed a brief flash of your inbox before the welcome screen appeared on a freshly installed copy of Hyperdrive.
- Fixed the sign-in screen's sizing being inconsistent with the rest of the welcome flow.
- Fixed a rare case where specially crafted styling in an email could bypass image- and font-blocking protections.
A Refined First-Launch Opening and Trustworthy Sign-Out
- The very first screen you see now plays a proper opening: a brief pause before the brandmark animates in, distinct from the animation you get on later launches.
- Sign-out now tells you if it didn't fully complete instead of reporting success while the account is still connected on the server.
- The classification and tracking consent screens each got their own icon.
- Fixed quitting onboarding before finishing sign-in leaving behind partial progress that caused the opening to be skipped on your next launch.
- Fixed the command palette's arrow keys and Return occasionally not responding.
- Fixed replying on a long-running thread sometimes addressing the wrong message.
- Fixed calendar invite actions showing a generic error instead of the actual problem.
- Fixed account deletion not fully removing an associated license binding, and data export now refuses to complete rather than produce an incomplete file.
Video Calls in Calendar Events, Protected RSVPs, and Safer Booking Links
- Add a video call to any event right from the editor. Hyperdrive only offers the services your account can actually use, and fetches or creates the join link automatically.
- If a link isn't ready yet, the event shows as pending and fills in the join details as soon as it's available — no need to touch it again.
- Connect a conferencing account once, then join its calls from any of your other linked accounts.
- Calendar invites now show which video service a meeting uses instead of hiding it.
- Fixed guest RSVP responses getting cleared when you made an unrelated edit to an event.
- Fixed a video-call connection that could show as connected when it wasn't, leaving invites with no working join link.
- Fixed a booking link tied to more than one account being accepted instead of failing safely.
- Fixed calendar sync skipping an event it couldn't process instead of retrying it later.
A Complete First-Run Setup Flow, with Progress Dots
- First-run setup now walks new accounts through one complete flow — turning on AI features, signing in, and choosing your tracking and classification preferences — instead of stopping partway.
- A row of progress dots shows how many setup steps are left as you go.
- Fixed existing accounts being sent back through the entire first-run setup after an update and asked again for consent they had already given.
- Fixed turning on AI features overriding a provider you had already configured, like Anthropic or OpenAI, switching you back to the built-in model.
One Undo System, Searchable Pickers, and an Inbox-Ready Notice
- Undo now covers far more: un-trashing, un-muting, moving a thread, applying a label, sending, unsubscribing, a learned rule, a tracking-scope change, and an RSVP can all be undone with the same shortcut.
- Move to folder, Label, View Original, and tracking-scope pickers now open on the same searchable card as Send Later and Remind Me.
- A notice tells you your inbox is ready right after launch or switching accounts.
- Fixed a security issue where a specially crafted reply could sneak a hidden recipient onto your outgoing message.
- Fixed turning off tracking for a recipient or domain not actually stopping their tracking beacon on your next email, and those settings sometimes sticking around after you signed out of the account.
- Fixed the command palette not focusing its search field when it opened, Enter not confirming the highlighted row, and Escape closing the whole palette instead of stepping back out of a submenu.
- Fixed not being able to type "j" or "k" while searching in any picker, and unblocking a sender not taking effect if you did it right after blocking them.
Never-Track List, Consistent Pickers, and Private Image Loading
- Manage your never-track list in Privacy settings. Anyone on it stays untracked, including on scheduled sends.
- Send Later, Remind Me, Labels, Move to folder, and View Original all open as the same centered card now, and cancelling one takes you back to the command palette.
- Threads tell you how many trackers were blocked.
- Un-archive is a real action you can run on any thread.
- Remote images load through Hyperdrive instead of the browser engine and are cached so they appear instantly next time. The cache is readable only by you.
- Timestamps update right away when you switch between 12- and 24-hour time.
- Fixed a scheduled send leaving the composer open, Send Now not sending, undo not fully reversing a send, and reopening a draft blanking it.
Drag-and-Drop Attachments, a Resizable Composer, and Full Activity History
- Drop a file on the composer to attach it. Labeled targets show whether it lands as an attachment or inline in the body.
- Drag the composer's top edge to whatever height you want, and it stays there until you change it.
- Activity now scrolls back through an account's entire history, loading more as you go, and refreshes the moment you launch or switch accounts.
- Stop tracking a single recipient, a whole domain, or an email you already sent.
- Fixed attachments failing to send.
- Fixed the composer never reopening after you collapsed it out of full screen, and a faded draft card swallowing clicks meant for the composer.
- Fixed a reply going to the wrong message, and a deleted draft coming back.
Draft Card, Scheduled Folder, and Tracking Controls
- Your unfinished message now sits in a card at the bottom of the thread. It slides open into the composer and back, and has its own Trash button.
- Scheduled messages wait in a Scheduled folder instead of cluttering Drafts, and the draft clears itself once the message goes out.
- Turn read receipts and link tracking on or off from the command palette or Privacy settings.
- Read a sender's mail exactly as they sent it, every time. Choose View Original for one thread or for that sender from then on.
- Deleting your account now takes an emailed confirmation before anything is removed.
- Light mode was retuned so the reading pane and side pane are easier on the eyes.
- Fixed Archive, Trash, and Mute acting on the wrong thread while a message was open, and New Message not opening after an abandoned draft.
One-Click Unsubscribe, Image Blocking, and View Original
- Unsubscribe from a mailing list in one click. A banner at the top of qualifying emails unsubscribes you, then archives the thread and blocks the sender so it stays gone.
- Block remote images by sender. When an email loads tracking images, a banner lets you load them once, always for that sender, or never.
- See any email exactly as it was sent. Press D on a thread to toggle View Original and read the raw, unstyled message, then toggle back.
- Drafts are clearer in your lists. Unfinished messages show a "[Draft]" tag in the thread list and search, and composing no longer bumps a thread to the top.
- Sign back in cleanly when a session expires. Hyperdrive now recognizes an expired sign-in, says so plainly, and walks you through re-authorizing.
- Fixed incremental sync dropping or misparsing some newly arrived mail.
Readable Dark-Mode Email and RSVP Reliability
- Dark-mode email is easier to read. Body text was lifted out of a too-dim grey, and each message keeps its own formatting on its own card.
- RSVPs are more reliable. Your response sends through the account's own provider, saves once, and the banner shows when a reply hasn't gone through yet.
- The side pane grows with your window. The widget pane and its tabs now expand and space themselves evenly as you resize.
- Fixed several dark-mode cases where message backgrounds or images washed out the text.
Meeting Invites in the Thread, Dark-Mode Fixes, and Full-Screen Compose
- Calendar invites show a banner right in the thread. Accept, decline, or open the event without leaving the email, read straight from the invitation.
- Dark mode reads correctly across more emails. Link colors, backgrounds, low-contrast text, and embedded images are handled so nothing disappears against a dark background.
- Reply full-screen when you want room. The composer gained a full-size toggle and can host a live reply or forward draft.
- The quoted original is editable and collapsible. Reply quotes seed into the editor as a block you can trim or expand instead of being tacked on at send.
- Resume a draft exactly where you left off. Drafts reopen by their own identity, including threaded reply and forward drafts.
- Fixed a flash where a thread briefly showed the previous email before painting.
Auto Draft, a Tasks Panel, and a Reading Gutter
- Let AI draft your reply. Auto Draft reads the thread and writes a reply in your voice, with a waiting indicator while it works, ready for you to edit and send.
- Drafts stay in sync. Drafts you edit or delete elsewhere are reconciled on sync, and empty drafts are kept out.
- A new Tasks panel. Track tasks in a dedicated side panel alongside your mail.
- A reading gutter for a narrower column. A collapsible left panel lets you tighten the reading width for long messages.
- The thread header is cleaner. The action bar folded into the subject row with smaller glyphs.
AI Reasoning Controls and Scheduling Link Polish
- AI features are tuned per task. Thread summaries run faster with reasoning off, while compose and classification keep it on for accuracy.
- Thread summaries are terser. The summary prompt drops boilerplate and keeps a tight history.
- The scheduling link editor matches the event panel. Creating and editing links now share the same clean layout.
- Reminders return you to the top of the inbox. Restored the original behavior where a reminder leaves the inbox and comes back on top.
- Fixed a crash on quit during shutdown of the on-device AI engine.
Drag to Edit Calendar Events and AI Rewrite Polish
- Create and edit events by dragging on the calendar. Drag on the grid to create, drag to move, and drag an edge to resize — on timed events, all-day rows, and the month view.
- The AI Rewrite panel gained a real editor. Rewrites open in a live, editable box you can undo in one step, with clear keyboard focus.
- The inline reply card is a proper floating card. It sits as a bounded card whose height grows elastically as you type.
- The event detail view was reorganized. Edit and Delete moved to clearer spots and the panel reads as a single tidy column.
- Fixed the calendar grid dragging the whole window on press-and-hold.
Drag Images Into Your Message and Smart Event Titles
- Drop an image straight into your message to embed it inline. Drag a photo onto the Composer and the drop zone splits so you can choose to attach it or place it inline in the body, whichever half you release over.
- Inline images just work, whatever the format. HEIC, TIFF, and similar formats are converted automatically when you drop them in, and if one can't be converted it falls back to an attachment with a heads-up.
- Events suggest their own title. As you fill in an event, Hyperdrive offers a smart title suggestion you can accept or dismiss from the keyboard.
- Fixed the event editor's tab order to follow the two-column layout, and tidied the AI settings model rows so labels sit left and buttons line up flush right.
Redesigned Event Editor and a Downloadable AI Model Library
- The event editor was redesigned into a clean two-column form. Calendar, Recurrence, and Location are always visible, the all-day toggle now sits on the Title row, and viewing and editing an event share the same tidy layout.
- Bring your own AI, with models you can download on device. The AI settings tab now includes a model library with clear download progress, plus proper dropdowns for choosing your provider and model.
- Small polish: the sync confirmation emoji is now centered on the sync dot.
Remind Me Everywhere, Drag-to-Attach, and Bring Your Own AI Key
- Set a Remind Me on a brand-new message, not just replies. The reminder arms the moment you pick it, rides along when the message sends, and cancels itself if you discard the draft.
- Schedule and reminder chips each get their own cancel button. When a message has both a scheduled send and a reminder, they show as two separate chips you can cancel independently.
- Drag files onto the Composer to attach them. Drop one or more files directly on the compose card and they're added to your message.
- Bring your own AI provider key. A new AI settings tab lets you choose your provider and enter your own API key, stored securely.
- Snooze is now part of Remind Me. Snoozing and reminders were merged into one simpler system, so there's a single way to bring a thread back when you want it.
- Event notes gained a taller two-line field, with a paperclip button to attach files right from the editor.
AI Rewrite, Richer Calendar Events, and Scheduled Send Chips
- Rewrite your draft with AI. A new Composer panel rewrites selected text and lets you steer the result by tone, with full keyboard control for cycling fields and stepping through tones.
- Choose your AI provider. Hyperdrive now runs AI features through a provider you select, and switching providers takes effect immediately on your next request.
- Calendar events gained real depth. Events now support all-day toggling, precise start and end times, time zones, availability and visibility settings, reminders, and attachments — on both the events you create and the ones you sync.
- New Calendar settings tab. Set your default event duration once and every new event picks it up.
- Scheduled sends show a chip in the Composer. When a message is queued to send later, a chip displays the scheduled time and cancels the send when clicked.
- Recipient chips toggle on click. Click a chip to swap between a contact's display name and their email address.
- Fixed daily celebration photos being downloaded larger than needed, and kept the celebration on screen when you re-enter quickly.
Link Previews, Consistent Lists, and Composer Polish
- See where a link goes before you click. Hovering a link in the Composer now shows a popover with its destination address.
- Every list in the app now behaves the same. Date presets, contact suggestions, dropdowns, and the schedule picker all share one list foundation, so selection, hover, and scrolling feel identical everywhere.
- Recipient chips show contact names. Chips now display a contact's display name instead of a raw address, with labels optically centered.
- Insert Link moved to Shift+Cmd+K to free up its previous shortcut.
- Hover behavior is more precise across dropdowns and contact suggestions, and rows now show a proper cursor.
- Fixed a list cursor flicker, keyboard hint bar spacing, and your text selection and focus not returning after the link sheet closes.
New Dropdowns and a Cleaner Date Picker
- Dropdowns are new across the app. They are fully keyboard navigable, respond to hover on both label and chevron, and size themselves to their content.
- The Send Later and Remind Me picker was redesigned. The date input and condition controls were rebuilt, spacing and dividers were corrected, and the wording reads properly now.
- Panel styling is consistent app-wide. Every floating panel, palette, and picker now draws from one shared set of styling rules.
Send Later, Remind Me, and a Fuller Accounts Tab
- Schedule a message or set a reminder from the Composer. A new picker lets you send later or remind yourself, including conditional reminders.
- Reminders that fire only if no one replies. Schedule a follow-up and it cancels itself automatically when a recipient replies first.
- Resume a draft straight from the thread. Pending sends and drafts now appear inline in the conversation, and clicking one reopens the Composer where you left off.
- The Accounts tab does much more. Pick a color per account and per calendar, see your calendars nested under the account they belong to, and connect or disconnect Slack workspaces and Zoom.
- Lists follow your cursor. The date picker, recipient suggestions, and command palette now scroll to keep the selected row in view, including when opened mid-list.
- Buttons are consistent app-wide, and recipient fields now show placeholder text.
- Fixed crashes when dismissing the schedule and snooze pickers, a Remind Me shortcut that did nothing, and drafts losing their conversation on autosave.
Text Color, Links, Account Management, and Instant Theming
- Color your text. A swatch picker sits under the paint palette button in the Composer, and the button's dot reflects the color at your cursor.
- Insert and edit links properly. A new link sheet applies to your selected text and lets you edit an existing link in place.
- The Accounts tab was rebuilt. Accounts are grouped by provider with connection badges, shortcut hints, and working Add and Remove actions.
- Reconnecting a disconnected account now just works. If a provider revokes access, Hyperdrive flags that account, offers a clear re-authorize action, and picks your mail back up afterward without a full resync.
- Signing out fully clears your data. Sign-out now revokes access, ends the session, and purges that account's local data in order.
- Theme changes apply everywhere, instantly. Switching palettes or typography now repaints every surface in the app at once, with no stale colors left behind.
- Security hardening across sign-in and account data handling.
- Fixed the After Archive dropdown clipping and lagging, the Composer caret not blinking when refocused, numbered and bulleted list styling in the editor, and floating panels flashing or landing off-center.
Collapsible Calendar Sections, Compose Reliability, and Sync Status Polish
- The calendar sidebar is now collapsible. Calendars and Scheduling Links each have reusable disclosure headers, smooth open/close animation, and their expanded state is remembered between launches.
- Keyboard control added for calendar sections. You can toggle the sidebar sections from the keyboard, with layout and animation routed cleanly through the shared app model.
- Compose autosave and focus behavior tightened up. Draft autosave now runs through the main-thread dispatcher seam, recipient data is serialized correctly, and focusing the editor places the caret at the end of your existing text.
- Status bar sync feedback is clearer. Sync now shows distinct Synced, Syncing, Offline, and Error states, including a per-poll spinner signal while background work is active.
- Multi-account visuals are more stable. Each account now gets its own color slot at sign-in, and older accounts are backfilled automatically so account colors stay distinct.
- Settings and build polish. Fixed the General settings appearance section collapse behavior, corrected light-mode recoloring there, restored the Hyperdrive app name and icon in the active Mac build, and persisted the OAuth URL scheme in project generation.
Scheduling Link Editing and Calendar Sync Reliability
- Edit scheduling links from the list. The pencil icon opens the editor prefilled with the link's current settings, and saving updates it in place instead of creating a new one.
- Confirmation dialog before deleting a scheduling link. A new reusable confirmation overlay asks you to confirm before the link is removed.
- Fixed calendar sync. A pagination bug was causing full calendar refreshes to fail with a server error; incremental sync is enabled again too.
- Scheduling credentials now provisioned securely at app launch, stored in the protected keychain instead of being created the first time you open the editor.
- Account activation now waits for valid credentials, preventing an account from silently ending up signed out after launch.
- Scheduling link rows polished. Copy button shows a "Copied" confirmation, title and duration text centered, hover-brighten effect on row and mini-calendar icons.
- Fixed a bug where clicks could pass through overlay panels to the content underneath.
- Compose change-tracking consolidated onto a single internal driver, closing a class of stale-refresh bugs.
Scheduling Link Editor and Calendar Sidebar Polish
- Create and edit scheduling links right in the app. Set duration, buffers, timezone, conferencing, and a custom availability grid for each link.
- Your scheduling links list now updates instantly after you create, delete, or sync a link.
- Fixed a crash that could happen when opening the scheduling link editor.
- Fixed an error creating a scheduling link when its name matched one you already had.
- The calendar sidebar's Agenda view keeps the current day's header visible while you scroll.
- Calendars and Scheduling Links lists now scroll in their own space instead of pushing the rest of the sidebar around.
- Renamed sidebar tabs for clarity: "Events" is now "Agenda" and "Info" is now "Contact."

- Efficient mutation tracking — pending mutations are snapshot-read once per sync page, reducing database traffic.
- Smart merge logic — sync intelligently merges Gmail's data with pending mutations. Fields that have pending changes are preserved.
- Full app bootstrap — HttpClient, GmailClient, SyncSystem, and AppState are all initialized and started when the app launches.
- Clean shutdown — AppState is properly reset on app exit to prepare for next launch.
Complete Email Actions
- Email operations — all user-facing actions are now implemented with full durability and optimistic UI: Star, Unstar, MarkRead, MarkUnread, Trash, Mute (archive), Move, AddLabel, RemoveLabel, and Snooze.
- Label management — add and remove Gmail labels from emails. Supports both Gmail system labels (Inbox, Unread, Starred) and custom labels.
- Archive (Mute) — removing from Inbox archives emails. Muted threads no longer appear in the inbox but remain in the database and can be searched.
- Move between folders — emails can be moved to any Gmail label. Moving automatically removes from the source folder and adds to the destination.
- Snooze — defer emails to a specified time. Snoozed emails are hidden from inbox until the snooze time expires, then reappear automatically.
- Robust error handling — storage failures and malformed payloads are logged with clear messages instead of silently failing.
- Thread-safe replay — background job safely replays queued actions without data races.
- Pre-flight validation — payloads are validated before dispatch to catch errors early.
Durable Actions & Optimistic Updates
- ActionQueue — persists all email mutations (star, unstar, mark read, archive, etc.) to the database before sending to Gmail. Ensures no action is lost even if the app crashes.
- Optimistic updates — when you perform an action, the UI updates instantly. The action is sent to Gmail in the background, and the UI stays responsive.
- Smart reversion — if the Gmail API call fails, the UI automatically reverts to the previous state. Users see a notification that the action failed.
- Offline support — actions are queued when offline. When connectivity returns, the queue automatically replays all pending actions.
- Automatic retry — transient failures (network timeouts, temporary server errors) automatically retry with exponential backoff. Max retry budget prevents endless loops.
- FIFO ordering — actions are replayed in the order they were performed, preserving causality.
- Offline indicator — when offline, the app shows a clear indicator so you know sync is paused.
- Specific actions implemented — Star, Unstar, MarkUnread with full durability and optimistic UI.
Email Sync Engine & Incremental Updates
- SyncSubsystem — core engine that fetches emails from Gmail and keeps them in sync with your local database. Handles full and incremental synchronization.
- Initial inbox load — when you first connect, all threads are fetched from your inbox and stored locally. Handles pagination for large inboxes (up to 10 pages).
- Folder synchronization — all Gmail labels (system and custom) are synced as folders. Keeps folder list up to date in the background.
- Incremental sync — after the initial load, only changes are synced using Gmail's history API. New messages, label changes, and deletions are tracked efficiently.
- Resume capability — sync progress (page tokens, history ID) is saved to the database. If sync is interrupted, it picks up from where it left off.
- Background polling — periodic polling of Gmail history keeps your email list fresh without constant full syncs.
- Proper cleanup — in-flight sync operations are cancelled when stopping to prevent orphaned requests or data corruption.
- Lifecycle management — clear phases (initial sync → folder sync → incremental polling) with proper state transitions and error handling.
Gmail Data Mapping & Network Resilience
- GmailAdapter — converts Gmail API responses into Hyperdrive's internal data format. Handles the full complexity of Gmail's nested message structure and label system.

- Message extraction — email bodies and headers are extracted from Gmail's payload tree structure. Handles both simple text messages and complex MIME structures.
- Attachment handling — automatically extracts regular and inline attachments from messages. Handles edge cases like missing payloads and empty threads.
- Folder mapping — Gmail labels (system and custom) are mapped to folder categories in Hyperdrive.
- Rate limiting — requests to Gmail API are rate-limited to stay within quota. Automatic backoff when Gmail returns rate-limit headers.
- Circuit breaker — if Gmail API starts returning errors, the client temporarily stops making requests to avoid cascading failures.
- Auth retry — authentication headers are automatically injected and refreshed, with retry logic for token expiration.
Swift-to-C++ FFI & Gmail Batch Sync
- C FFI bridge — Swift on macOS can now call C++ app state, observables, and lifecycle management. Enables direct UI binding to core state.
- Complete Gmail API coverage — all PRD-specified endpoints implemented (list threads, get profiles, batch operations, etc.).
