Zed v1.5.3 Changelog

This update focuses heavily on polishing Zed's built-in AI assistant, making it smoother and more helpful for developers who want to automate their workflow. It also brings welcome visual improvements, like better diagram rendering and more clickable links, making the editor feel more connected and responsive for everyone.

What's new

• AI Assistant Upgrades: You can now rename your AI chat threads directly in the sidebar, reorder your projects up and down, and click on file paths wrapped in backticks (like src/main.rs) to instantly open that file at the exact line.
• Faster AI Models: Added "Fast Mode" for OpenAI models, which puts your requests at the front of the line so you get answers quicker. The list of available models also now refreshes automatically without needing to restart the app.
• Clickable Documentation Links: If a language server (a background helper that understands your code) includes a web link in its documentation, you can now click it directly in the editor.
• Better Git Integration: You can now change the font size when writing commit messages. Zed also added recognizable icons for different code-hosting websites like GitLab, Bitbucket, and Codeberg.
• Markdown and Mermaid Improvements: Mermaid diagrams (which let you draw charts using text) are now faster and more accurate. You can also use shift+click to select text in Markdown previews, and there's a new button to wrap or unwrap long lines of code in Markdown files.
• Remote Dev Containers: When using dev containers (isolated coding environments that package up everything you need), you can now use local features that weren't available before.

Improvements

• AI Readability: When the AI reads a file, it now shows line numbers next to the code, making it much easier to follow along. Scrolling through large files the AI reads is also noticeably smoother.
• AI Notifications: If an AI task finishes while you have that project collapsed in the sidebar, a little indicator will pop up so you don't miss it. If the AI asks for your permission to run a tool and you scroll past it, it will stay visible so you don't get stuck waiting.
• Git Performance: Opening the view to see what you've changed (the diff view) is now much faster, even if you've edited a ton of different parts of a file. Creating a new Git worktree (a way to work on multiple branches at the same time) is smarter because it now fetches the latest main code before building it.
• Rust Toolchains: If you're coding in Rust, Zed is better at using the exact set of tools your project asks for, rather than a default one.

Fixes

• AI Glitches: Fixed a bug where the AI wouldn't follow your global instructions when writing Git commit messages. Also fixed an issue where you wouldn't see an error message if the AI tried to edit a file and failed.
• AI Crashes: Squashed two crashes—one that happened when folding sections of the AI panel, and another that happened when searching for tools in the AI settings.
• Helix Mode Fixes: Fixed several issues in Helix mode (a keyboard-centric editing style), including crashes when pasting at the end of a file and keyboard shortcuts that were accidentally triggering Vim commands instead of Helix ones.
• Git and Project Fixes: Fixed an issue where failing to fetch a Git branch would stop the rest of your Git status from updating. Also fixed a glitch where switching recent projects would always send you to the main workspace instead of the exact folder you left off in.
• UI Fixes: Fixed a visual bug where the AI's suggested code edits would get hidden behind the right sidebar.
