Changelog

.cursor/rules, Better Codebase Understanding, New Tab Model

• .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 (0.45.1-0.45.6): 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 and team-configurable blocklists.
