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.

Invalid AWS region environment values are reported instead of hidden

You'll notice
Useful2 Signal2
Bedrock

An invalid AWS_REGION is now reported as invalid rather than silently treated as default.

AWS_REGIONAWS_DEFAULT_REGION
What

When AWS_REGION or AWS_DEFAULT_REGION is set to something that does not validate, Bedrock region detection now reports the source as env-invalid rather than pretending it used the default, and falls back to us-east-1.

Evidence

env-invalid

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