Claude Code v2.1.310 release introduces a new Monitor tool, improves cloud session management and code review features, and includes several bug fixes.

READY TO POST:

anthropic's claude code v2.1.310 just dropped, adding a new monitor tool for bedrock, vertex, and foundry. pretty neat for devs building on those platforms.

big update for claude code! looks like they're beefing up cloud session permissions and fixing a bunch of annoying bugs with prompts and file handling. always good to see more stability.
