v1.9.3 is a bug-fix release on the v1.9.x line. It ships the small set of fixes accumulated between v1.9.2 and the start of the v2.0.0 work, and is the recommended last stop on the v1.9.x line for deployments that are not yet ready to upgrade to v2.0.0.
- Hotfix roll-up of the fixes accumulated after v1.9.2. The multi-tenancy and password-policy changes are not part of this release; they ship in v2.0.0.
v1.9.3 is a drop-in replacement for v1.9.2: no schema changes, no permission changes, no behavior changes. Apply the upgrade during a normal maintenance window using the standard Migration guide.
When you are ready to move to the multi-tenant Organizations model, plan the v2.0.0 upgrade separately. v2.0.0 is the release that introduces PostgreSQL Row-Level Security and the new Organizations permission model — see the Upgrading to v2.0.0 guide for the full procedure, pre-upgrade checklist, and rollback constraints.
