Zed ships 1.28.1 stable and 1.29.1 preview with new Git and Claude features

Zed Industries released version 1.28.1 on its stable channel and 1.29.1 on its preview channel on November 11, 2026, adding Git workflow tools, an agent safety fix for oversized file reads, and preview support for new Claude models, according to the stable release notes.

What changed in 1.28.1 and 1.29.1

• The stable channel adds optional automatic Git fetching through the git.auto_fetch.enabled setting.
• The stable channel adds a resizable Refs column in the Git Graph view and lets users drag and drop files from the Git Panel into terminals or editors.
• The stable channel's agent read_file tool now truncates lines over 2,000 characters to avoid context window overflow.
• The stable channel also fixes Helix mode clipboard handling and macOS SSH connection issues.
• The preview channel adds a Git Panel branch mode that lists every file changed since a base branch, a bookmark picker, and configurable Git date formats through the git.date_format setting.
• The preview channel adds support for Claude Fable 5.2 and Claude Mythos 5.2 in the Anthropic provider, plus a new agent.auto_generate_thread_titles setting enabled by default.

What it means for people building with AI

Zed Industries continues to tighten its native agent and Git tooling on a near weekly cadence. The read_file truncation in the stable channel guards against a common agent failure mode: blowing out the context window when an agent reads an oversized file. The branch aware Git Panel in the preview channel lets developers list everything changed since a base branch, making it easier to review agent made changes before merging.

Availability

The Git auto fetch option, resizable Refs column, drag and drop support, read_file truncation, and the Helix and SSH fixes are live now in Zed's stable channel, version 1.28.1. The branch mode Git Panel, git.date_format setting, support for Claude Fable 5.2 and Claude Mythos 5.2, and the new agent.auto_generate_thread_titles setting are available on Zed's preview channel, version 1.29.1, as detailed in the preview release notes.
