Velocity5.0

Open-source computer-based assessment and testing platform.

Every visible release is a backport, and the same feature flag is being threaded across four version lines

assessment-platformbackportsfeature-flagsrelease-lineseducation
Current state
Four releases inside five days, all of them backports. Three carry the same dual preview feature — first as a feature flag onto the 56.3.1 and 56.3.5 lines, one of them explicitly based on the 2026.07 construct line, then the feature itself onto 56.1.19. The fourth is a UI library version bump backported to a 55.0.1 build.
Where it's heading
What this window shows is release-line management rather than product development: a single feature is being carried across at least four concurrently maintained versions, gated behind a flag on the newer lines. That is the shape of a platform with institutional customers pinned to specific builds, where shipping anything means shipping it several times.
Prediction
Expect the dual preview flag to keep propagating to remaining supported lines, and for it to be enabled by default on a construct line once the flagged rollout holds.
