In `@source/administration-guide/upgrade/important-upgrade-notes.rst`:
- Around line 32-45: The upgrade note’s lock-timing statement is too absolute.
Update the description around the useraccesstokens migration and its
lastnotifiedat column to state that PostgreSQL performs a catalog-only operation
without a table rewrite, and that execution is quick after acquiring the
required ACCESS EXCLUSIVE lock, which may wait behind conflicting transactions.

In `@source/deployment-guide/software-hardware-requirements.rst`:
- Around line 140-142: Update the Release Date entries for v10.11 ESR and v11.7
ESR in the software and hardware requirements table to the canonical metadata
dates: 2025-08-15 and 2026-05-15, respectively.

In `@source/product-overview/ui-ada-changelog.rst`:
- Line 38: Update the changelog entry’s UI labels by applying bold formatting to
“Regenerate” and “Account Settings > Security,” matching the formatting style
used by surrounding entries while preserving the existing wording.
