v3.30.0

Added

• Flags emoji category. The emoji picker has a new Flags category with a broad set of country flags. The US flag leads the list, followed by two classic American flags — the Betsy Ross flag and the Gadsden ("Don't Tread on Me") flag — which ship built in and render inline in messages and reactions like any other emoji.
• Screen share pop-out maximize toggle (#5430). The screen-share pop-out window now has a maximize/restore toggle so a shared stream can fill the pop-out.

Improved

• Smarter emoji search. Typing an actual punctuation mark now finds the matching emoji — e.g. ? surfaces ❓ and ⁉️, ! surfaces ❗, and # or a digit matches its keycap emoji. Search also covers the new bundled flag emoji by name.

Fixed

• "New messages" divider and auto-scroll stopped appearing (#5432). Opening a channel recorded it as fully read before its history finished loading, so the last-read divider from #5259 had nothing to anchor to. The read position is now saved after the history request, restoring the divider and the jump-to-unread scroll.
• Channel-scoped role permissions leaked server-wide (#5433). Per-assignment permission checkboxes ticked on a role granted inside a specific channel (e.g. "create channel", "rename sub-channels") were being applied everywhere. They're now scoped to the channel they were granted in and its sub-channels; server-wide assignments still apply everywhere as before.

Changed

• README refresh (#5431). Documented custom stickers and personas, the built-in backup tools, and the :: persona shortcut, marked the Russian translation as human-reviewed, and updated roadmap statuses.
