CHANGELOG.md

@@ -27,6 +27,9 @@ All notable changes to this project will be documented in this file.
 - Mobile: Chats — sessions that belong to no project — now appear in the sessions sheet above the project list; opening an already-open agent switches to its editor instead of duplicating it (thanks to @bashrusakh); Android connections can trust user-installed certificate authorities, such as a local proxy's (thanks to @Silvenga).
 - Settings: the editor font size survives a restart (thanks to @pascalandr); a change made right before closing the window is saved (thanks to @makeittech); number fields and selects no longer clip at large font sizes (thanks to @makeittech); refreshing GitHub account state no longer interrupts the page (thanks to @floze-the-genius); the Cloudflare Tunnel download link is fixed (thanks to @AyoubAchour); Windows skill paths are classified correctly, so disabled and duplicate skills are hidden as intended (thanks to @Ttungx).
 - Small model: requests send the provider's configured headers, such as an API-gateway subscription key (thanks to @dmitrii-galantsev); a configured Anthropic endpoint is used without a doubled `/v1`, and Google models without reasoning no longer receive a thinking option (thanks to @mpeter and @IngTian).
+- Projects: the folder picker can select several directories at once and add them together (thanks to @herjarsa).
+- Files: files reached through a symlink inside the workspace, or under a project root that is itself a symlink, open again instead of failing with an access error (thanks to @herjarsa).
+- Settings/Providers: after saving an API key or signing in, the provider no longer shows "Credentials missing" with its models hidden until you switch away and back (thanks to @herjarsa).
 - Projects: the folder picker can enter a directory that is already a project to browse from there (thanks to @weixiang1862), and sending, forking, and image attachments work in projects whose path has non-ASCII characters, such as `Masaüstü` (thanks to @fitzgpt).
 - Git: the status panel refreshes from real repository state after checkout, branch, stash, merge, rebase, or reset, and remote branches that were never fetched appear in branch lists (thanks to @makeittech); the Branch diff scope no longer compares against the wrong base for branches created from the current branch (thanks to @gaojunran); picking `origin/main` in the branch selector checks out the local branch instead of a detached `HEAD` (thanks to @yulia-ivashko); branch search hides non-matching branches (thanks to @bashrusakh).
 - Updates: "Update OpenCode" no longer fails with a bare "Bad Request" — OpenChamber names the release to install and shows OpenCode's reason when refused — and the desktop "Restart to Update" button shows why an install failed, including an unsigned local build, and stays available to retry (thanks to @mdatsev and @yulia-ivashko).

 - Sidebar: pending permission and question badges are no longer covered by the hover actions (thanks to @makeittech); worktree branch search hides non-matching branches (thanks to @bashrusakh).

 - Settings: number fields and selects no longer clip at large font sizes (thanks to @makeittech), and Windows skill paths are classified correctly, so disabled and duplicate skills are hidden as intended (thanks to @Ttungx).
 - Windows: closing VS Code now stops the managed OpenCode process instead of leaving it running (thanks to @a0000001).
 - The extension reuses its OpenCode output channel across managed-server restarts instead of creating duplicates (thanks to @TTTPOB).
