This release adds video wallpapers, case and regex switches in find, a shortcut sheet and paged loading of long conversations, lets the reading column go narrower, and fixes several saving, pasting and display problems.
New
- A wallpaper can be an MP4 or WebM video, played muted and looping; it stays on its first frame while the window is hidden or unfocused, under reduced motion or reduced effects. Refs #14357.
- The find bar gained two switches: match case, and read the query as a regular expression. Refs #14198 by @imcreazy.
- The appearance settings gained a keyboard shortcut sheet listing every chord the window answers to, reachable by searching "shortcut", "Ctrl" or "Esc". Refs #14198 by @imcreazy.
- Agent browser pages can sleep when idle (Settings → Appearance): a page nobody drives for 15 minutes is folded away and wakes as the same tab. Off by default. Refs #14332 by @jf200s.
- A version download, started from the version list or by automatic download, can now be cancelled; cancelling stops the transfer and removes the partial files. Refs #14338.
- An optional history API reads the transcript in bounded pages with stable positions and cross-page tool context; existing clients keep full reads. Refs #14048, #14087 by @SivanCola.
Changed
- Wallpapers have no 12 MB limit and are used as chosen; the upload is written to disk as it arrives and served in ranges, so a large one no longer fills memory. Refs #13980.
- The reading column can be dragged continuously down to 640px instead of stopping at 760px; Home and an untouched window still give 760px. Refs #14384.
- The reading column's resize grips no longer draw at rest; they appear under the pointer or on keyboard focus, and dragging and keys are unchanged. Refs #14352 fixed in #14353.
- Removed Widen mode, its button and Ctrl/Cmd+Shift+B; use the divider or the arrow keys on it to resize. Refs #14324 fixed in #14335 by @lancy69.
- A long conversation folds neighbouring questions in the rail into one line and names the range on hover; right click stars one. Refs #14198 by @imcreazy.
- The run analysis entry reads as words beside its icon, the page has a back arrow, and picking a conversation already on screen returns to reading. Refs #14198 by @imcreazy.
- A conversation can be exported as Markdown, keeping only the questions and answers in order; JSON still carries every field. Refs #14198 by @imcreazy.
- With dispatch on, a task sent to a project in your sidebar no longer stops on its trust card because you hadn't decided about it yet. Refs #13341.
- With no chosen or remembered project, a first launch opens a small folder the app owns instead of your home directory; it is never remembered as a project. Refs #14363.
- Type description keywords after
/to find skills and commands; name matches still rank first. Refs #14323 fixed in #14344 by @lancy69. - A tool call missing a required field, a todo list breaking a rule, and a diff citation for command-made changes now show a valid example or the files-evidence way out. Refs #14311.
- Paging servers show the latest messages first; older pages keep your reading position and controls, and search says when history is incomplete. Refs #14048, #14087 by @SivanCola.
Fixed
- Pasting a screenshot works after returning to the Send feedback tab or clicking the dialog heading, and a paste right after opening is no longer sometimes ignored. Refs #14205 fixed in #14333 by @lancy69, #14333 by @lancy69.
- A question starred in the rail before a new conversation is first saved stays starred, and no longer reappears in another unsaved conversation after a restart. Refs #14296 by @imcreazy.
- A request reported with zero cache hits counts as a full miss, so the hit rate no longer drifts up; over-reported hits are clamped and 99.5% no longer shows as 100%. Refs #14313 by @jf200s.
- The notice shown when a background job starts is worded in the interface language instead of staying the one English line. Refs #14308.
- The reading column's grips no longer stop after the first drag; sidebars give way while dragging and the composer follows the width. Refs #14320 by @imcreazy.
- Opening the todo plan no longer pushes the message rail or the jump buttons up; the panel floats above the composer. Refs #14321 by @imcreazy.
- The line shown after a context fold is one sentence in the interface language, not an English key=value dump. Refs #14307.
- Workbench text menus combine editing and Add to conversation, respect read-only views and selection, and keep focus and undo/redo. Refs #14326 fixed in #14348 by @lancy69.
- An unanswered ask card keeps its picks, typed text, notes and current question when it scrolls out of view and back. Refs #14336 fixed in #14337.
- A conversation bound to an Agent preset no longer turns read-only after an upgrade changes a built-in tool; it continues with the recorded tools and says so once. Refs #14360 fixed in #14370.
- The running / failed / action counts on the activity line now share the title's size and weight. Refs #14364.
- When the title model spends its whole output budget thinking, automatic naming asks once more with room for the title instead of failing. Refs #14374.
- The "Import a native session" card in Settings → Storage no longer shows the browser's own file input; it uses an app-styled button. Refs #14378.
- Reads by child tasks, the Planner and the Guardian use their own records and no longer refresh the executor's stale-file guard and overwrite your edits. Refs #14025, #14133 by @SivanCola.
- The Guardian's own
use_capabilitycalls enforce read-only execution on the real target, refusing writes and declared host mutations. Refs #14025, #14133 by @SivanCola. - After a restart with Git unavailable, an isolated result keeps its files and ID; recovery checks managed paths and repository identity, and a mismatched record stays untouched. Refs #14025, #14133 by @SivanCola.
- Optimistic task writes honour live sibling claims, including dynamically resolved local tools; disjoint writes stay parallel. Refs #14025, #14133 by @SivanCola.
Upgrade notes
- Dispatching to a sidebar project you have not decided about records it as trusted and sends the task; folders that cannot be trusted whole, such as your home directory, still ask. Refs #13341.
- In optimistic mode, a write to a file a sibling task holds is refused with write.path_busy instead of silently overwriting it. Refs #14025.

Full Changelog: studio-v2.50.0...studio-v2.51.0
macOS 已用 Developer ID 签名并公证，打开时不需要清除隔离属性。Windows 的窗口、内核与安装器都经 Certum 代码签名证书做了 Authenticode 签名。Linux Debian 系从 .deb 安装，Fedora、RHEL、openSUSE 等从 .rpm 安装（sudo dnf install ./ReasonixStudio-linux-amd64.rpm）。x86_64 用文件名带 amd64 的包，aarch64（统信 UOS、麒麟等）用带 arm64 的包。也提供 .AppImage（只提供下载，不会自更新；需要 FUSE 2，或用 --appimage-extract-and-run 启动）。
三个平台都能自更新：Linux 的 .deb 走自己的包（.rpm 的自更新尚未提供，请手动下载新包），Windows 运行下一个安装器，macOS 替换自身 bundle。
