+  **General**
+
+  * Fixed a startup freeze on Macs that keep applications in iCloud Drive with Optimize Mac Storage turned on.
+  * Fixed scheduled task problems: "every N days/months" schedules ran on the wrong days (existing tasks move to the correct days on their next run), re-enabling a task or editing its schedule immediately started a catch-up run for a time slot that passed while it was off, and manually run tasks sometimes did not record when they last ran.
+  * Fixed the app crashing when signing in with Touch ID on macOS; Touch ID passkey sign-in is temporarily unavailable.
+  * Fixed the app quitting on macOS when the disk was full or when stopping dictation.
+
+  **Code**
+
+  * Fixed archiving an SSH session discarding uncommitted or unmerged work in its remote worktree; the worktree is now kept, and unarchiving recreates it if it is missing so the session can pick up where it left off.
+  * Fixed session history no longer updating or appearing lost on macOS for sessions in folders whose names contain accented, Korean, or Japanese characters.
+  * Fixed sessions you hadn't opened for 30 days or more losing their conversation history even though the app was in regular use.
+  * Fixed SSH connections on slow or unstable networks failing on the first attempt and needing a manual retry.
+  * Fixed SSH sessions losing a task that was still running when the app reconnected after an app update.
+  * Fixed the side chat answering once and then failing with an authentication error for the rest of a long session.
+
+  **Cowork**
+
+  * Fixed conversations failing to open when a message contained a very long run of bracketed text, a very long line starting with an unclosed `[`, or a very long run of `>` characters.
+  * Fixed message ratings and "Send feedback" links sometimes appearing when your organization has product feedback turned off.
+  * Fixed sessions failing to start on managed Macs where the app's temporary directory is not writable.
+
+  **3P**
+
+  * Changed gateway device-code sign-in to refresh silently when the gateway also issues a refresh token, instead of prompting you to sign in again each time the access token expires.
+  * Fixed an ended gateway device-code sign-in going unnoticed while the app was idle; the app now notices at its next periodic configuration check or shortly after the computer wakes from sleep and asks you to sign in again, and the Setup window says "Session expired" instead of "Denied".
+  * Fixed Cowork file previews showing "Preview unavailable" until the app was restarted once a preview pane had been closed for a few minutes.

     "Nonessential" covers two things: **product-usage analytics** (which features get used, navigation patterns; no prompts or completions) and the **Send** action in Help → Generate Diagnostic Report. Turning this on stops both.
 
-    Destination for both: `claude.ai`. Already listed under Egress Requirements → Nonessential telemetry.

   <Accordion title="disableNonessentialServices details">
-    "Nonessential services" covers four outbound fetches the app runs without: **connector favicons** (the icon proxy), the **connector directory** lookup (the Anthropic MCP registry), the **artifact-preview** iframe origin, and the **MCP Apps widget** iframe origin (`*.claudemcpcontent.com`). Turning this on blocks all four.

-    **What you lose when this is on:** connectors show without icons, the connector directory can't be fetched, artifacts do not render in conversations, and connectors that return MCP Apps show the text tool result instead of the widget.
