BlueMind Webmail (Mail App)​

  • BM-23961: Fixes: Internal anchor links in emails do not work.
  • BM-24196: Improved performance of the folder context menu.
  • Fixes: Several out-of-office emails are active in the database, causing an incorrect out-of-office status to be displayed.

Calendar​

  • BM-23762: Fixes: When adding an external ICS file whose URL contains an ‘&’, an “Invalid URL” error message is returned.

Search (Contacts & Calendar)​

Thunderbird​

  • BlueMind preferences now open the new version of the preferences manager.

Administration​

Directory (AD)​

  • BM-24214: Fixes: Inconsistency during the connection test in GC mode; the test button does not take the mode into account.
  • BM-24217: Fixes: A standard domain administrator was able to change the import type — only ‘admin0’ should be authorised to make this change.
  • BM-24218: Fixes: The label for the ‘split domain’ field remains visible in GC mode even though the field is hidden.

Core​

  • BM-24172: Fixes: Upgrade is interrupted if it starts whilst the authentication service (Keycloak) is not yet fully ready.
  • BM-24216: Fixes: Failure to perform an upgrade on certain enhanced database configurations, due to an optional diagnostic feature.

Indexing (Elasticsearch)​

  • BM-24173: Fixes: Search errors lasting several seconds after a search engine node is restarted.

MAPI / Outlook (reliability/performance)​

  • Fixes and optimisations to improve the reliability and speed of mass reconnections by Outlook clients (for example, following a server restart):
    • New server settings have been added to adjust the management of MAPI connections, sessions and queues during periods of high reconnection activity.
    • Implementation of a throttling mechanism (admission gate) limiting the number of connections processed simultaneously during a massive influx, to prevent server overload and enable a faster and more stable recovery.
    • Reduced the time taken to establish an Outlook session (caching, asynchronous processing, batching of folder checks) during these peak load periods.
  • Fixes: Unnecessary and repeated repairs to access rights for system folders upon reconnection.
  • Fixes: A bug that could prevent the directory (address book) from functioning correctly after a restart of the index database (KeyDB), resulting in certain entries becoming untraceable.
