Ecosystem Impact
All three enterprise cloud providers (Bedrock, Vertex, Foundry) reappear together after being absent from the last 5 releases—echoing the coordinated pattern last seen in v2.1.31. VS Code, present in 4 of the last 10 releases, is notably absent from this 22-item drop.

May Help If You've Noticed
Claude Code unexpectedly launches inside itself and you end up with two nested sessions conflicting with each other
You can't log in or check auth status without going through the full interactive setup wizard each time
Claude crashes mid-task with no visible error when a tool processes or returns image data during streaming
Hook scripts fail and you see the exit code but have no idea what stderr output caused the block
@file references with a #section anchor never resolve, even though the file clearly exists
