  ## [3.75.543] - 2026-08-26 ### Added - Nymbot works inside channel message threads. Opening a thread on one of its messages and replying there continues the conversation with no `?` prefix or `@Nymbot` mention needed, and Nymbot answers inside the thread instead of the flat channel. The whole thread is sent as its context, so a game started or continued in a thread (`?trivia`, `?wordle`, `?riddle`, `?anagram`) keeps its state. In a thread rooted on someone else's message, `?commands` and `@Nymbot` mentions still reach it and are answered in that thread; it only replies unprompted once it is already the thread's last speaker. - Slack-style message threads across channels, PMs, and group chats. Tapping a message (or its "N replies" row under the reactions/zaps row) swaps the current view to the thread — the root message plus its replies — using the same composer, and the chat header's back/forward buttons navigate in and out of threads. Desktop hover actions gain a thread button beside quick react/translate, and the long-press menu gains "Reply in Thread". On by default; a new "Message Threads" setting (synced across devices) restores the classic flat view. Channel replies carry a NIP-10 marked `['e', rootId, '', 'root']` tag so other clients still see a normal channel message; PM/group replies carry `['nymthread', rootNymMessageId]` inside the encrypted rumor. ### Fixed - Outgoing event signing (every send, read receipt, presence ping) now uses native libsecp256k1 when available — the CPU profile showed the pure-Dart path costing 10-20 ms of BigInt math ON THE UI THREAD per signature, which is scroll-time jank whenever receipts fire. The gift-wrap worker isolates load the native library too, so seal signing and seal verification inside PM processing take the fast path as well. - The iOS scroll jank measured in the DevTools captures (a quarter to a third of ALL frames blowing the raster budget, spikes to 60–127 ms) traced to ~23 offscreen render passes (`Canvas::saveLayer`) per frame. The dominant source was SVG icon tinting: a srcIn colorFilter forces vector_graphics to saveLayer every icon, every frame, and 15–25 tinted icons are always on screen (header, composer toolbar, the per-row add-reaction pills, badges). Icons now tint via the SVG theme's `currentColor` — resolved at parse time, rendered identically, no offscreen pass. The add-reaction pill's and the composer translate button's resting `Opacity` dims are likewise folded directly into their colors. - The fullscreen image viewer now opens media from the shared disk cache the inline tile already populated, instead of re-downloading it with a separate uncached fetch. - The "Stay Connected in Background" descriptions (settings and the network stats modal) now say the mode uses more data as well as more battery. - Opening a thread from another conversation no longer throws a "Cannot use ref after the widget was disposed" error storm: the post-frame callback captured the tapping row's ref, which the view switch itself could dispose before the frame ended. It now captures the provider notifier. - The whole-app freezes during the first minutes after opening (scroll not responding, the sidebar stalling) are fixed at their two sources. The periodic cache flush serialized every dirty conversation, every known profile and every reaction tally to JSON on the UI thread every few seconds while the catch-up backfill kept marking stores dirty — that now happens in a worker isolate, writes only what actually changed, and the finished rows are committed as before in one transaction. And the live relay inflow, which rebuilt the visible message list for every arriving batch (many per second during catch-up), is paced to at most ~6 list updates per second — plus unchanged visible rows are now reused verbatim across those rebuilds instead of being rebuilt from scratch each time. - Force-closing and reopening the app no longer visibly re-downloads and re-renders the whole message history (and no longer re-uploads already- archived PM wraps). Boot previously gave the local cache only 1.5 seconds before connecting to relays; a heavy account's hydration — decoding tens of thousands of cached messages, previously on the UI thread — lost that race, so the app came up empty and re-fetched everything. Cache decoding now runs in a worker isolate and the network waits for hydration to land. - Link previews no longer fire an unfurl request for every link-bearing message the moment it scrolls into range — the card waits until it has been on screen ~300ms, so flinging through history stops causing a burst of network fetches and mid-scroll relayouts. - Event signature verification now uses the native libsecp256k1 library (bundled per platform) instead of pure Dart — ~70 µs per event instead of ~12 ms (~150×) — with the pure-Dart implementation kept as an automatic fallback wherever the library is unavailable. Together with the persisted verification cache this removes the boot/resume CPU grind entirely, first run included. - Animated GIFs and animated custom emoji now pause whenever they are off screen (scrolled away, behind another screen) instead of decoding frames forever, and resume exactly where they froze when scrolled back — a chat full of GIFs no longer keeps the CPU/GPU busy for as long as it is open. - Opening the app on an account with lots of history no longer pegs the CPU for seconds while messages stream in. Signatures verified in past sessions are now remembered on disk, so the boot/resume relay replay of already-seen reactions, profiles, presence and history skips the ~12 ms-per-event signature math (a seeded replay measures ~460× faster in the benchmark), and verification batches now run one at a time instead of fanning out across every core. - Images decode at the size they are shown instead of their full resolution: avatars, inline media tiles, link previews, GIF-picker cells, banners and composer thumbnails all cap their decode to the on-screen pixels, cutting the decode CPU, GPU texture uploads and image-cache churn that made media-heavy conversations stutter. - The loading skeleton no longer rebuilds its entire placeholder tree on every animation frame — the shimmer is repaint-only now — and the wallpaper, ambient glow, typing dots and skeletons each render in their own layer, so a tiny animation can't force the full-screen background patterns to re-draw at 60fps. - Debug builds no longer collapse into a per-frame exception storm (and the heavy lag it caused on startup as messages load) whenever a conversation contains a custom `:shortcode:` emoji. The emoji's inline baseline-shift render object read its `size` while the surrounding paragraph was still laying out, which Flutter's debug asserts (before the framework's 3.41 fix, flutter/flutter#176906) treat as an error — the thrown assert aborted the paragraph's layout mid-flight and corrupted the whole message list into re-throwing every frame. The baseline is now computed from a height recorded during the render object's own layout pass, which is legal on every Flutter version. - Tapping a quoted block inside an open thread now leaves the thread and jumps to the original message in the conversation, instead of silently doing nothing because the thread list never held it. - The app dialog (including the post-quantum `nympq1…` recovery-code paste prompt) now lifts above the soft keyboard instead of hiding its input behind it, matching the other keyboard-aware modals. ## [3.74.542] - 2026-08-25 ### Added - Quantum-resistant messaging now works with browser-extension and remote-signer logins in both directions, not only when sending. Synced settings and archived history are covered too. - A post-quantum recovery code (`nympq1...`) that a second device is linked with, shown beside the nsec in View or Edit Nym's Details. ### Changed - The Nym details modal opens on your full public key, with the nickname below it, and explains that the `#` suffix is the last four characters of the key's hex spelling. - The shield no longer claims full quantum resistance on a message that only got part of it. ### Fixed - A manually translated message is no longer cleared when a new message arrives. - The pop-out composer keeps its rounded corners, and the formatting toolbar is no longer hidden behind it. ## [3.74.535] - 2026-08-24 ### Fixed - Settings changes now stick. A save that failed for any reason was still recorded as done, so it was never retried and the change reverted the next time the app opened. - A setting one app knows about and the other does not is no longer wiped when the other app saves the section it lives in. - The app language and the auto-translate options are stored in the same place the web app stores them, instead of a second location the two kept overwriting. ## [3.74.534] - 2026-08-23 ### Fixed - The quantum-resistant badge now updates as soon as a message is sent or upgraded, instead of staying blank until the app was reopened. - A message that arrived conventionally encrypted and was later delivered quantum-resistant now shows that straight away, matching how the sender verification mark already behaved. - Your own settings, message archive and self-addressed copies are sealed to a key this device can always reopen. Another device on the same account could previously seal them to a key this one had never held, leaving them permanently unreadable. - Key announcements are no longer re-fetched in bulk from relays on every reconnect; they are read from the archive, as everything else already was. ## [3.74.533] - 2026-08-23 ### Fixed - Post-quantum keys are now announced on a first connect, not only after a reconnect, so a newly signed-in account is discoverable straight away. - The announcement no longer rides the tail of the archive restore, which could skip it for a whole session when that restore was throttled or failed. - Peers' announced keys survive a relaunch, so the first message after a restart is post-quantum instead of falling back to classical while discovery re-runs. - Key lookups check the archive before fanning out to relays, and wait past the first "nothing here" answer, both of which could leave a conversation classical between two capable clients. - Your own sent message shows its quantum-resistant badge immediately, instead of staying unmarked until the app was restarted and the chat reopened. - Group messages now report how many members received a quantum-resistant copy. - The attachment preview no longer disappears when its upload finishes. - Media translated on demand is no longer asked for a language you already chose when you first opened the app. ### Changed - Attachments are now shown as tiles you can remove or retry individually, each with its own progress wheel, replacing the single upload bar that covered the previews and could not say which file it was waiting on. A failed upload keeps its file so one tap retries it, and the links are added to the message when you send rather than typed into the box as each upload lands. ## [3.73.533] - 2026-08-22 ### Added - WYSIWYG text editor for the message composer. - Inline image and video previews in messages. ## [3.73.532] - 2026-08-21 ### Fixed - All commands now appear in the app's localized language. ## [3.73.531] - 2026-08-20 ### Fixed - Various bug fixes. ## [3.73.530] - 2026-08-20 ### Added - Bluetooth mesh in supporting browsers. ## [3.73.529] - 2026-08-20 ### Fixed - Sidebar bugs. ## [3.73.528] - 2026-08-19 ### Fixed - Multiple bug fixes. ## [3.73.527] - 2026-08-19 ### Fixed - Many bug fixes and performance improvements. ## [3.73.526] - 2026-08-19 ### Fixed - Performance improvements. ## [3.73.525] - 2026-08-19 ### Fixed - Bugs when leaving groups. - Sidebar now shows channel locations. ## [3.73.524] - 2026-08-18 ### Fixed - Further bug fixes with Nymbot premium models. ## [3.73.523] - 2026-08-18 ### Fixed - Many bugs related to Nymbot premium models. ## [3.73.522] - 2026-08-17 ### Changed - Local message store is now an encrypted SQLite database. ## [3.73.521] - 2026-08-17 ### Changed - Refinements to the encrypted group chats implementation. ## [3.73.520] - 2026-08-14 ### Fixed - Missed inline script breaking CSP. - Stale messages showing as new. ## [3.73.519] - 2026-07-11 ### Added - Localized translation of the entire app. - Auto-translate messages into your preferred language.

Tapping a

  message (or its "N replies" row under the reactions/zaps row) swaps the current view to the thread — the root message plus its replies — using the same composer, and the chat header's back/forward buttons navigate in and out of threads. Desktop hover actions gain a thread button beside quick react/translate, and the long-press menu gains "Reply in Thread". On by default; a new "Message Threads" setting (synced across devices) restores the classic flat view. Channel replies carry a NIP-10 marked `['e', rootId, '', 'root']` tag so other clients still see a normal channel message; PM/group replies carry `['nymthread', rootNymMessageId]` inside the encrypted rumor. ### Fixed - Outgoing event signing (every send, read receipt, presence ping) now uses native libsecp256k1 when available — the CPU profile showed the pure-Dart path costing 10-20 ms of BigInt math ON THE UI THREAD per signature, which is scroll-time jank whenever receipts fire. The gift-wrap worker isolates load the native library too, so seal signing and seal verification inside PM processing take the fast path as well. - The iOS scroll jank measured in the DevTools captures (a quarter to a third of ALL frames blowing the raster budget, spikes to 60–127 ms) traced to ~23 offscreen render passes (`Canvas::saveLayer`) per frame. The dominant source was SVG icon tinting: a srcIn colorFilter forces vector_graphics to saveLayer every icon, every frame, and 15–25 tinted icons are always on screen (header, composer toolbar, the per-row add-reaction pills, badges). Icons now tint via the SVG theme's `currentColor` — resolved at parse time, rendered identically, no offscreen pass. The add-reaction pill's and the composer translate button's resting `Opacity` dims are likewise folded directly into their colors. - The fullscreen image viewer now opens media from the shared disk cache the inline tile already populated, instead of re-downloading it with a separate uncached fetch. - The "Stay Connected in Background" descriptions (settings and the network stats modal) now say the mode uses more data as well as more battery. - Opening a thread from another conversation no longer throws a "Cannot use ref after the widget was disposed" error storm: the post-frame callback captured the tapping row's ref, which the view switch itself could dispose before the frame ended. It now captures the provider notifier. - The whole-app freezes during the first minutes after opening (scroll not responding, the sidebar stalling) are fixed at their two sources. The periodic cache flush serialized every dirty conversation, every known profile and every reaction tally to JSON on the UI thread every few seconds while the catch-up backfill kept marking stores dirty — that now happens in a worker isolate, writes only what actually changed, and the finished rows are committed as before in one transaction. And the live relay inflow, which rebuilt the visible message list for every arriving batch (many per second during catch-up), is paced to at most ~6 list updates per second — plus unchanged visible rows are now reused verbatim across those rebuilds instead of being rebuilt from scratch each time. - Force-closing and reopening the app no longer visibly re-downloads and re-renders the whole message history (and no longer re-uploads already- archived PM wraps). Boot previously gave the local cache only 1.5 seconds before connecting to relays; a heavy account's hydration — decoding tens of thousands of cached messages, previously on the UI thread — lost that race, so the app came up empty and re-fetched everything. Cache decoding now runs in a worker isolate and the network waits for hydration to land. - Link previews no longer fire an unfurl request for every link-bearing message the moment it scrolls into range — the card waits until it has been on screen ~300ms, so flinging through history stops causing a burst of network fetches and mid-scroll relayouts. - Event signature verification now uses the native libsecp256k1 library (bundled per platform) instead of pure Dart — ~70 µs per event instead of ~12 ms (~150×) — with the pure-Dart implementation kept as an automatic fallback wherever the library is unavailable. Together with the persisted verification cache this removes the boot/resume CPU grind entirely, first run included. - Animated GIFs and animated custom emoji now pause whenever they are off screen (scrolled away, behind another screen) instead of decoding frames forever, and resume exactly where they froze when scrolled back — a chat full of GIFs no longer keeps the CPU/GPU busy for as long as it is open. - Opening the app on an account with lots of history no longer pegs the CPU for seconds while messages stream in. Signatures verified in past sessions are now remembered on disk, so the boot/resume relay replay of already-seen reactions, profiles, presence and history skips the ~12 ms-per-event signature math (a seeded replay measures ~460× faster in the benchmark), and verification batches now run one at a time instead of fanning out across every core. - Images decode at the size they are shown instead of their full resolution: avatars, inline media tiles, link previews, GIF-picker cells, banners and composer thumbnails all cap their decode to the on-screen pixels, cutting the decode CPU, GPU texture uploads and image-cache churn that made media-heavy conversations stutter. - The loading skeleton no longer rebuilds its entire placeholder tree on every animation frame — the shimmer is repaint-only now — and the wallpaper, ambient glow, typing dots and skeletons each render in their own layer, so a tiny animation can't force the full-screen background patterns to re-draw at 60fps. - Debug builds no longer collapse into a per-frame exception storm (and the heavy lag it caused on startup as messages load) whenever a conversation contains a custom `:shortcode:` emoji. The emoji's inline baseline-shift render object read its `size` while the surrounding paragraph was still laying out, which Flutter's debug asserts (before the framework's 3.41 fix, flutter/flutter#176906) treat as an error — the thrown assert aborted the paragraph's layout mid-flight and corrupted the whole message list into re-throwing every frame. The baseline is now computed from a height recorded during the render object's own layout pass, which is legal on every Flutter version. - Tapping a quoted block inside an open thread now leaves the thread and jumps to the original message in the conversation, instead of silently doing nothing because the thread list never held it. - The app dialog (including the post-quantum `nympq1…` recovery-code paste prompt) now lifts above the soft keyboard instead of hiding its input behind it, matching the other keyboard-aware modals.

  ## [3.74.542] - 2026-08-25 ### Added - Quantum-resistant messaging now works with browser-extension and remote-signer logins in both directions, not only when sending. Synced settings and archived history are covered too. - A post-quantum recovery code (`nympq1...`) that a second device is linked with, shown beside the nsec in View or Edit Nym's Details. ### Changed - The Nym details modal opens on your full public key, with the nickname below it, and explains that the `#` suffix is the last four characters of the key's hex spelling. - The shield no longer claims full quantum resistance on a message that only got part of it. ### Fixed - A manually translated message is no longer cleared when a new message arrives. - The pop-out composer keeps its rounded corners, and the formatting toolbar is no longer hidden behind it. ## [3.74.535] - 2026-08-24 ### Fixed - Settings changes now stick. A save that failed for any reason was still recorded as done, so it was never retried and the change reverted the next time the app opened. - A setting one app knows about and the other does not is no longer wiped when the other app saves the section it lives in. - The app language and the auto-translate options are stored in the same place the web app stores them, instead of a second location the two kept overwriting. ## [3.74.534] - 2026-08-23 ### Fixed - The quantum-resistant badge now updates as soon as a message is sent or upgraded, instead of staying blank until the app was reopened. - A message that arrived conventionally encrypted and was later delivered quantum-resistant now shows that straight away, matching how the sender verification mark already behaved. - Your own settings, message archive and self-addressed copies are sealed to a key this device can always reopen. Another device on the same account could previously seal them to a key this one had never held, leaving them permanently unreadable. - Key announcements are no longer re-fetched in bulk from relays on every reconnect; they are read from the archive, as everything else already was. ## [3.74.533] - 2026-08-23 ### Fixed - Post-quantum keys are now announced on a first connect, not only after a reconnect, so a newly signed-in account is discoverable straight away. - The announcement no longer rides the tail of the archive restore, which could skip it for a whole session when that restore was throttled or failed. - Peers' announced keys survive a relaunch, so the first message after a restart is post-quantum instead of falling back to classical while discovery re-runs. - Key lookups check the archive before fanning out to relays, and wait past the first "nothing here" answer, both of which could leave a conversation classical between two capable clients. - Your own sent message shows its quantum-resistant badge immediately, instead of staying unmarked until the app was restarted and the chat reopened. - Group messages now report how many members received a quantum-resistant copy. - The attachment preview no longer disappears when its upload finishes. - Media translated on demand is no longer asked for a language you already chose when you first opened the app. ### Changed - Attachments are now shown as tiles you can remove or retry individually, each with its own progress wheel, replacing the single upload bar that covered the previews and could not say which file it was waiting on. A failed upload keeps its file so one tap retries it, and the links are added to the message when you send rather than typed into the box as each upload lands. ## [3.73.533] - 2026-08-22 ### Added - WYSIWYG text editor for the message composer. - Inline image and video previews in messages. ## [3.73.532] - 2026-08-21 ### Fixed - All commands now appear in the app's localized language. ## [3.73.531] - 2026-08-20 ### Fixed - Various bug fixes. ## [3.73.530] - 2026-08-20 ### Added - Bluetooth mesh in supporting browsers. ## [3.73.529] - 2026-08-20 ### Fixed - Sidebar bugs. ## [3.73.528] - 2026-08-19 ### Fixed - Multiple bug fixes. ## [3.73.527] - 2026-08-19 ### Fixed - Many bug fixes and performance improvements. ## [3.73.526] - 2026-08-19 ### Fixed - Performance improvements. ## [3.73.525] - 2026-08-19 ### Fixed - Bugs when leaving groups. - Sidebar now shows channel locations. ## [3.73.524] - 2026-08-18 ### Fixed - Further bug fixes with Nymbot premium models. ## [3.73.523] - 2026-08-18 ### Fixed - Many bugs related to Nymbot premium models. ## [3.73.522] - 2026-08-17 ### Changed - Local message store is now an encrypted SQLite database. ## [3.73.521] - 2026-08-17 ### Changed - Refinements to the encrypted group chats implementation. ## [3.73.520] - 2026-08-14 ### Fixed - Missed inline script breaking CSP. - Stale messages showing as new. ## [3.73.519] - 2026-07-11 ### Added - Localized translation of the entire app. - Auto-translate messages into your preferred language.
