Summary

Timelake became something to install and keep running: every release on the usual registries, tables that record their format version and upgrade without data loss, and one registry of settings that turns each feature on or off per table, session or call. Releases follow releases.

  • 2026-10-14: format versions, timelake upgrade and rollback (0.3.0); registries and installers (0.4.0)
  • 2026-10-17: settings registry (0.5.0)
  • 2026-10-19: milestone written when the specs were regrouped one per feature.
