# Major fixes: Chat input is now truly silently intercepted to prevent titles and descriptions from being broadcast. Fixed issues with voting result caching rollback, duplicate topics, and asynchronous reactivation after deletion. Management operations and scheduled maintenance are now handled asynchronously by the database. Fixed issues where notifications of voting completion failed and were not retried. Added tests for abnormal chat paths and cache race conditions in Paper/Bukkit. Fixed an abnormal rollback issue with the Folia adapter.
