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.
Engine builds recognised by the version-timestamp parser
Under the hood
Useful1Signal0
Elsewhere
Build-age checks now read timestamps correctly from a second class of internal builds.

What
The helper that pulls a build timestamp out of a version string now understands -engine. prerelease tags, so engine builds get correct build-age handling.
Details
previously only -dev. tags matched
the version-normalising replace matches both forms as well
Evidence
/-(?:dev|engine)\.(\d{8})\.t(\d{6})(?:\.|$)/g
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
