**[Google Antigravity 2.2.1: Integrated System Keyring and Multi-Agent Deadlock Fixes]** According to monitoring by Beating, Google Antigravity has released version 2.2.1. Addressing the frequent issue of authorization failures faced by developers, the new version supports automatically writing refreshed OAuth credentials into the operating system's secure keyring (e.g., Apple Keychain or Windows Credential Manager), eliminating repetitive web authorization pop-ups. Additionally, workspace search has been upgraded to substring matching mode, fixing path-not-found errors caused by prefix-based searches and resolving deadlock issues during sub-agent operations. Multimedia and environmental compatibility have also been optimized. The new version introduces the ability to directly play audio formats such as .mp3 and .wav in the sidebar and deliverables window, while also adding syntax highlighting for C++, Python, and Protobuf in Markdown. For Windows platform users, the update resolves repeated UAC permission prompts and errors accessing the system environment variable PATH directory. The system also includes a built-in "Antigravity Guide" skill to address platform usage questions. However, some developers encountered obstacles during the upgrade and usage experience. Community feedback indicates that anomalies in the upgrade channel have left some users stuck on version 2.1.4, with no updates available. Additionally, the client is now forcibly fixed at a resolution of 1400x900 pixels upon each startup, and the new version has removed the inline command editing feature previously triggered by Ctrl+I, drawing complaints from many users.
