It fixes the in-app browser being completely unusable, brings Windows notifications back, and stops the Project Explorer from showing the wrong project. ###### In-App Browser Works Again - Every in-app browser tool call used to hang for 25–30 seconds and then fail with a misleading timeout error, making the whole feature unusable. Tool calls now return properly. - On Windows the browser failed to start at all. Fixed. - When no browser is attached, the error now tells you what to do — open the side browser panel — instead of leaving the agent guessing. ###### Windows Notifications - Desktop notifications never appeared on Windows even with notifications and scheduled-task alerts turned on. They now deliver correctly. ###### Bug Fixes - Switching between conversations in different projects no longer leaves the Project Explorer painting the previous project's file tree, and no longer wipes a project's saved folder-expand state. - Antigravity team members created through the team-creation flow no longer fail every turn with zero output. - Changing the theme in WebUI now applies immediately instead of waiting on a desktop-only relay. ###### Engine updates (AionCore v0.1.59 → v0.1.61) - The backend halves of the v2.1.49 features now land: client-hosted terminals, preview v2 (force-refresh Office documents from disk, detect in-place content edits), and AskUserQuestion as a first-class capability. - Codex conversations that appeared to "stop replying mid-answer" were background commands being reported as cancelled while still running. Fixed. - A corrupted internal process-registry file no longer breaks session startup — every message send used to fail until the file happened to heal itself, leaking an agent process each time. - Assistant rules created before user-scoping are no longer lost after adopting into an AionPro account. ##### What's Changed * fix(team): create antigravity team members with an empty model instead of the 'default' placeholder by @piorpua in https://github.com/iOfficeAI/AionUi/pull/3887 * fix(notification): register Windows AppUserModelID for NSIS toast delivery by @piorpua in https://github.com/iOfficeAI/AionUi/pull/3890 * docs: refresh README product descriptions across locales by @IceyLiu in https://github.com/iOfficeAI/AionUi/pull/3888 * fix(explorer): publish active project synchronously on conversation switch by @tcp404 in https://github.com/iOfficeAI/AionUi/pull/3875 * fix(browser): stop in-app browser MCP commands hanging, and fix Windows spawn EINVAL (#3883) by @IceyLiu in https://github.com/iOfficeAI/AionUi/pull/3885 * fix(theme): sync webui toggle state immediately by @IceyLiu in https://github.com/iOfficeAI/AionUi/pull/3892 * chore: bump version to 2.1.50 by @kaizhou-lab in https://github.com/iOfficeAI/AionUi/pull/3897 * ci: create source-only draft release upstream while keeping builds gated by @kaizhou-lab in https://github.com/iOfficeAI/AionUi/pull/3899 **Full Changelog**: https://github.com/iOfficeAI/AionUi/compare/v2.1.49...v2.1.50 --- ##### 📦 Download Installers are no longer published on GitHub.
