// HOW THIS ISSUE IS MADE

We read every release from the 174 tools on our watchlist at the source — GitHub and GitLab release notes, vendor release pages and changelogs, project blogs and feeds, vendor press releases, and the source code behind the tag. Bug-fix-only releases and non-product newsroom noise are dropped; what's left is summarized down to the new capability, how to try it, and any screenshots or videos the release itself published. Every entry links to the sources it was built from.

◆ AI Coding Agents

Anthropic Claude Code

v2.1.63 NOTES

Claude Code is an agentic coding tool that lives in your terminal, understands your codebase, and helps you code faster by executing routine tasks, explaining complex code, and handling git workflows - all through natural language commands.

Claude Code v2.1.63 adds HTTP hooks, /simplify & /batch slash commands, and cross-worktree config sharing.

└──▷ TRY IT

Opt out of claude.ai MCP servers entirely for a session — useful in air-gapped or compliance-restricted environments.

$ ENABLE_CLAUDEAI_MCP_SERVERS=false claude

›Adds /simplify and /batch bundled slash commands.
›Adds HTTP hooks: POST JSON to a URL and receive JSON back, as an alternative to shell command hooks.
›Adds ENABLE_CLAUDEAI_MCP_SERVERS=false environment variable to opt out of claude.ai MCP servers.
›Improves /model command to display the currently active model in the slash command menu.
›Project configs and auto memory are now shared across git worktrees of the same repository.

└──▷ TRY IT

Get personalized programming insights based on your session history directly from the CLI.

$ /insight

›Adds /insight CLI command for personalized programming insights, with weighted tips to increase feature discovery.
›Adds clipboard image support and an attachment UI to the CLI, enabling image content to be pasted directly into prompts.
›Supports MCP readOnlyHint annotation in plan mode, allowing read-only MCP tools to run without triggering write restrictions.
›Adds automatic backup of settings.json before any auth modification.

└──▷ BREAKING ON UPGRADE

!The coder-model and qwen3.5-plus model entries have been merged, and vision auto-switching has been removed — setups relying on automatic vision model switching will no longer behave as before.
!The environment variable GEMINI_CLI_INTEGRATION_TEST is renamed to QWEN_CODE_INTEGRATION_TEST; any CI or scripts that set the old variable must be updated.
