• .cursor/rules: Users can write several repository-level rules to disk in the .cursor/rules directory. The Agent will automatically choose which rule to follow.
• Deepseek models: Deepseek R1 and Deepseek v3 are supported in 0.45 and 0.44. You can enable them in Settings > Models. We self-host these models in the US.
• Summarize Previous Composers: When conversations grow too long, you can start a new conversation while referencing the previous one.
• Agent sees recent changes: The agent can use a tool to see your recent changes. It also sees changes made between user messages.
• Better Codebase Understanding: We've trained a new model for Codebase Understanding. We'll be rolling it out to all users on 0.45 in the coming week.
• Fusion Model: We've trained a new Tab Model that is substantially better at jumps and long context. We'll also be rolling this out to users shortly.
• Optional Long Context: When tagging long files, users have the option to request a larger context window with premium models. This will use more fast requests.

UPDATE (0.45.1-0.45.11): Fixes issue with older agent conversations, indexing stability, downloading incorrect extension versions, missing package on windows, crash on opening long composer sessions, latency on pasting code.

Also adds MCP support, team-configurable blocklists, fixes Composer stuck on generating issue for some windows builds, exit code 5 crashes, and improves MCP UI. Also several improvements to memory usage.

UPDATE (0.45.12-13): Update infrastructure improvements. The F1 > "Check for Updates" command should now work.

• Agent sees terminal exit codes, can run commands in the background, and commands are now editable
• Agent reads linter errors to automatically fix issues
• With Yolo Mode, the agent can auto-run terminal commands
• @docs, @git, @web, and @folder are now available in the agent
• Agent auto-saves changes to disk
• Agent can decide to edit multiple locations in parallel
• Agent can reapply edits with a smarter apply model
• Composer changes and checkpoints are now persisted across reloads
• Cursor Tab can make larger edits at a time
• Better UX to review changes in Composer
• 4o Support for Agent
• Cheaper and faster Bug Finding Model

Bug Fixes

• Fixed edge case where Cursor Tab crashed
• Fixed stuck on generating bug in chat/composer
• Composer no longer looks at files that were deleted
• Fixed code selection edge-case for chat/apply
• Cursor starts up faster

UPDATE (0.44.1–0.44.11): Fixes and improvements to dev containers, chat codeblocks on windows, and the agent. Decreases Cursor Tab Latency on Remote SSH. Fixes bug that prematurely triggered the free trial ended popup. Better observability for errors and crashes.

• Composer UI in the sidebar with inline diffs
• Early version of an agent in composer that can pick its own context and use the terminal
• Generation of git commit messages
• File pill recommendations in chat/composer
• @Recommended in chat/composer to semantically search for context
• Nicer image-dropping experience
• Several performance improvements
• Beta: Sneak peek at an upcoming bug finder feature

• Composer history lets you access previous composer sessions after restart. You can also edit and resubmit from previous messages within a session.
• We have made slight improvements to Debug with AI and added back @Lint Errors in Chat.
• VS Code 1.93.1: Cursor is now based on VS Code 1.93.1.
• Python auto import for Cursor Tab is much more stable in this release.
• Switching models is a lot easier with model search (Cmd-option-/) in the chat, composer, and cmd-k input boxes.
• Composer now only applies files that are in context to prevent hallucinations.
• Using cursor . with WSL should now be more stable.

UPDATE (0.42.1 - 0.42.5): Fixes the following upstream security issue: CVE-2024-43601. Also fixes a few composer bugs and a bug with Cursor Tab. Allows composer to auto apply to files not in its context. Also includes additional mitigations to CVE-2024-48919. Reduces a few long-tail connection errors. Adds escape hatch when Claude predicts the wrong filepath in chat.
