Important

Merging this PR will create a new release.

Features

• Bring in Sable Call, our fork of element call, which introduces camera settings, screenshare settings, echo cancellation, noise suppression, automatic gain control, and avatars in calls. (#127 by @melogale)
• added a /sharehistory command to share encrypted history with a user (#296 by @dozro)
• Push notifications now use event_id_only format — Sygnal never sees message content or sender metadata, and encrypted messages are decrypted client-side when the app tab is open (#295 by @Just-Insane)
• Added a toggle to enable/disable showing the call button for large (> 10 member) rooms. (#308 by @7w1)
• Added the ability to edit the description of a file and streamlined the image and video ui (#282 by @nushea)

Fixes

• Add Ctrl+F / Cmd+F keyboard shortcut to open Sable search instead of browser find-in-page (#304 by @Just-Insane)

• Add Vitest testing infrastructure with example tests and contributor documentation (#297 by @Just-Insane)

• Fix animated avatars not looping. (#307 by @7w1)

• Fix camera turning on by default when starting a call from the room header button (#305 by @Just-Insane)

• Fix duplicate unread badges on the /direct/ icon for DM rooms already shown as individual sidebar avatars (#289 by @Just-Insane)

• Fix emoji color bleeding into adjacent text in read receipt display names on Safari/WebKit (#303 by @Just-Insane)

• Fix notification dot badge appearing off-center on sidebar avatars (#306 by @Just-Insane)

• Fix excessive whitespace between the thread root message and replies in the thread drawer (#302 by @Just-Insane)

• Fix thread messages to include the required m.in_reply_to fallback pointing to the latest thread event, so unthreaded clients can display the reply chain correctly per the Matrix spec. (#288 by @Just-Insane)

• Fix spurious scroll-to-bottom and MaxListeners warnings on sync gap: stable callback refs and prevEventsLength guard in RoomTimeline, correct CallEmbed .bind(this) listener leak, stable refs in useCallSignaling, and unreadInfoRef to stop per-message listener churn (#279 by @Just-Insane)

• Fix URL preview scroll arrows appearing when there is no content to scroll (#301 by @Just-Insane)

• fix of compatibility of voice messages with element clients and style misshaps (#286 by @dozro)

• Account switcher: show a confirmation dialog before signing out of an account. (#310 by @Just-Insane)

• Autocomplete: pressing Enter now selects the highlighted item instead of sending the message. The first item is highlighted on open and ArrowUp/Down navigate the list while keeping typing focus in the editor. Focus returns to the message editor after completing a mention or emoji. (#310 by @Just-Insane)

• Adding account: show a "Cancel" button next to the "Adding account" label so users can abort the flow. (#310 by @Just-Insane)

• Message editor: add autoCapitalize="sentences" to respect the OS/keyboard capitalisation setting on mobile. (#310 by @Just-Insane)

• Notifications: add "Favicon Dot: Mentions Only" setting — when enabled, the favicon badge only changes for mentions/keywords, not plain unreads. (#310 by @Just-Insane)

• Video and audio messages: volume level is now persisted across page loads via localStorage and shared between all media players. (#310 by @Just-Insane)

• Reduced-motion: add animation-iteration-count: 1 so spinners stop after one cycle instead of running indefinitely at near-zero speed. (#310 by @Just-Insane)

• Server picker: prevent iOS from restoring the old server name while the user is actively editing the input. (#310 by @Just-Insane)

• Browser tab/PWA: use the correct light (#ffffff) and dark (#1b1a21) theme-color values via media attribute on the meta tags. (#310 by @Just-Insane)
