What
Background worker and daemon respawn now understands a second prerelease channel and refuses to upgrade across channels.
Details
- The version regex accepts
engine alongside dev|alpha|beta|rc|test|nightly as a prerelease tag - A new helper set
["dev", "engine"] classifies a version by which of those tags its build string contains - A
-dev. worker is not respawned as -engine. or vice versa; previously only the dev tag was understood - This build reports VERSION "2.1.219"
Evidence
nightly|engine
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
