DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Module initialisers replaced by plain constants

Under the hood
Useful1 Signal0
Startup

Many message and pattern tables became plain constants with identical contents.

What

Many lazily built module bodies are now top-level constants with identical contents: Bash safety patterns and flag sets, plugin cache error strings, the MCP transport table, Remote Control refusal messages, cloud-hook explanations, workflow harness preamble text, PowerShell and environment sanitisation lists, and session name word lists. Load shape only, no visible change.

Evidence

bridge_carrier_no_ingress_origin

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
