Pre-launch changelog: entries describe the foundation under active validation, not a generally available production release.
Pre-launch foundation
Introduced the RankUp brand, mobile-first five-destination app shell, source-versioned content model, deterministic mastery and progression rules, competitive match foundation, and consent-aware AI workflows.
How content changes are recorded
Publishing creates an immutable question version. Corrections create a new version, while retired items remain visible in historical results and disappear from new study and competitive sessions.
What future entries will include
Each release entry will summarize user-visible changes, affected platforms, important source or policy updates, migration notes when needed, and the date the change became available.
