Zed v1.27.0：弃用 Agent Checkpoint，移除 macOS 11 支持

This week's release includes syntax highlighting for Go 1.27 generic methods, an option to open README files by default, and AI commit messages that follow your repository's recent commit style.

Features

• Improved Agent Panel memory usage by loading tool-call diffs and parsing thread message Markdown only when first viewed, instead of when loading a thread. (#65444, #65470; thanks Vanuan)
• Improved AI commit message generation by using the three most recent repository commit messages as style examples. (#61528; thanks matheuslrd)
• Improved CPU usage and disk reads while the agent was working, especially with a long thread history. (#66015)

• Added missing tooltips to the close, commit message, and "View on" buttons in the Git Graph's commit details panel. (#66016; thanks skmanoj322)
• Improved Git Graph rendering performance. (#66180; thanks RemcoSmitsDev)
• Improved the Git Panel's error message when a push was rejected because the local branch was behind the remote, explaining that remote changes must be fetched and integrated before pushing again. (#47296; thanks Aladiah96)

Languages

• Added syntax highlighting for Go 1.27 generic methods. (#64562; thanks ndellosa95)

Breaking Changes and Notices

• Removed support for macOS Catalina and Big Sur. Zed now requires macOS 12.0 (Monterey) or later. (#65994)
• Removed agent checkpoints and the "Restore Checkpoint" button. Taking a checkpoint before every message made the agent slow to respond, or hang, in large Git repositories. To undo the agent's changes, reject its edits or use Git. (#65989)
