Engine builds recognised by the version-timestamp parser

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.
