Night shift report

WHY THIS MATTERS: Claude Code 2.1.303 shipped to npm (October 18), two days after 2.1.302. Its whole changelog is "Bug fixes and reliability improvements", so nothing new needs learning. It still gets a PR because every version bump does, and coming this soon after 2.1.302 (which added CLAUDE_CODE_AUTO_MODE_MODEL) it looks like a stabilization patch. The one real wording change is in the Cowork / desktop changelog. Grouping sessions by environment used to be described as the sidebar behavior. Now it is described as one option in the sidebar's Group by menu. So environment grouping is a choice, not a forced default.

HIGHLIGHTS:

  • Claude Code v2.1.303: the only changelog entry is "Bug fixes and reliability improvements", in both CHANGELOG.md and the code.claude.com changelog page. The manifest moves from 2.1.302 to 2.1.303 on all 8 platform binaries.
  • Cowork changelog (content/claude/cowork/changelog.md): "Changed the sidebar to group sessions by environment..." became "Added Environment to the sidebar's Group by menu", which groups by saved local/SSH environment, or by folder/repo when there is none. "Custom groups are now called sections" is unchanged. Still not available in third-party deployments.
  • Support (57 articles): noise only. Intercom image URLs got new expires/signature tokens and the text is unchanged.
  • discovery.json / tombstones.json: only the updated date changed. No new sources, no new deaths, no resurrections. No files were deleted.
