Release 8.43

This release brings refinements across the UI and middleware for improved stability, configurability, and performance. The UI now offers extended options to promote storage upgrades and includes a wide range of fixes improving accessibility, consistency, and reliability across mail, calendar, and task features. On the middleware side, new configuration properties enhance calendar conflict checks, attendee lookups, and reminder handling. Additional improvements include updated library dependencies, timezone data, and optimized data processing routines for smoother operation and easier maintenance.
