Claude Code Now Tells You Every Time It Blocked a Tool Call, and Your GitHub CLI Token Can Finally Expire

22 Oct 2026

Claude Code's stable, latest and next channels now serve the same build, and it can report every tool call it stopped to your telemetry.
Claude Code no longer sends an HTTP MCP tool call twice when a connection drops, and self-hosted runner checkout hooks now have a default time limit.
GitHub CLI can sign in with short lived tokens that refresh themselves, which breaks scripts that save a token for later.
A Copilot CLI prerelease retires two remote startup flags, and the current release stops duplicate subagent approval prompts.
