Claude Code 2.1.80 adds rate limit visibility, MCP push messaging, and memory improvements
Claude Code 2.1.80 is a release that adds several practical features for developers using the AI coding assistant, focusing on visibility, configuration, and performance improvements.
Key features in 2.1.80
- Rate limits visible in statusline: You can now see rate limit status directly in the interface instead of guessing when you're being throttled.
- Inline plugin config via settings.json: Configure MCP plugins directly in the settings.json file without editing separate configuration files.
- --channels flag (research preview): Enables MCP push messaging for server-to-client notifications.
- Per-command effort overrides: Set different effort levels for specific slash commands.
- 80 MB saved on startup: Memory reduction that's noticeable when running multiple sessions.
- Fixed --resume dropping parallel tool results: Resolves an issue where parallel tool results were lost when using the --resume flag.
The release notes mention that the --channels flag is currently in research preview, indicating it's an experimental feature for testing MCP push messaging functionality.
