Zed Ships 1.5.3 Stable and 1.6.0 Preview on the Same Day

Zed Industries released two versions on June 3: version 1.5.3 to the stable channel and version 1.6.0 to the preview channel. They cover different ground, but together they sketch out where the editor is heading on AI and Git tooling.

Zed 1.5.3: What’s Stable

Mermaid rendering got a speed and accuracy pass. Diagrams render faster and the output is more reliable than in previous versions. This is a relatively minor improvement on top of the Mermaid support that landed a few releases back, but it matters if you’re using the agent to generate diagrams in the panel.

Document links are now enabled by default. Language servers can emit clickable links in their output, which Zed will now render as actual hyperlinks in the editor. If you want the previous behavior, you can turn it off with "lsp_document_links": false in settings.

Thread renaming arrives in the sidebar. You can now rename agent threads directly from the panel without going into settings. This is a small quality-of-life improvement for anyone running multiple sessions, since auto-generated thread names based on the first message are often too long or too vague to scan at a glance.

Git hosting got more logo support: Bitbucket, Codeberg, Forgejo, Gitea, and GitLab now all have icons in the Git panel alongside the existing GitHub support. Markdown got a UI control for wrapping and unwrapping code block contents. Remote development in dev containers got improved local feature support.

Bug fixes include a long-standing issue where commit message generation ignored global instructions, agent panel crashes, and a batch of Helix mode keybinding conflicts.

Zed 1.6.0 Preview: What’s Coming

Fast mode is the headline preview feature. It’s available for Anthropic and OpenAI models in the agent panel. Fast mode trades per-token cost for response speed: you pay more per token but the agent responds faster. The exact pricing depends on which model and plan you’re on.

This follows a similar feature that Claude Code and other tools have offered. The tradeoff is explicit rather than automatic, so you decide when the speed is worth it.

Shareable agent skill links let you distribute a skill configuration by URL. If you’ve built a skill for a specific workflow and want teammates to use the same setup, you can share a link rather than walking them through the configuration.

agent.commit_message_instructions is a new setting that lets you customize how Zed generates AI commit messages. If you have a specific format your team requires, like a ticket number prefix or a particular summary style, you can encode that here instead of editing every generated message by hand.

Claude Opus 4.8 is now supported as a BYOK (bring your own key) option. Thread management expanded to include regenerate, rename, and archive actions beyond the existing rename-only support.

Git improvements in the preview include split diff mode in commit history, total added and removed line counts in the Git panel, SHA-256 object format repository support, and a new “compare with branch” action.

File finder got a usability fix: you can now open a file from the finder without dismissing it, using the right arrow key or a “Keep Open” button. Previously, selecting a file closed the finder.

Markdown frontmatter is now rendered as metadata rather than raw text. Language model connections got support for custom HTTP headers, which is useful for enterprise deployments that route API traffic through proxies.

Status

Version 1.5.3 is stable and available to all users now. Version 1.6.0 is in the preview channel, which you can opt into in Zed’s settings.
