Outlook / MAPI

Administration / Architecture

• BM-22136 : Fix: Interpretation of ; character as separator in CSV imports.

API

• BM-22743: Fixed: IMailboxFoldersByOwner does not work for groups.

Clone

• Fix: Exclude external URL from sysconf comparison, as Redis only has an external URL. This could prevent the cloning process from starting.
• Fix: Always apply the blacklist before doing anything else. Otherwise, older entries that have not been deleted (from version 5.2.x onwards) are problematic.

Core

• BM-22153: Fixed: Unable to send hoster report.

sds

• Feature: Added support for split paths in S3 storage — Designed to help MinIO-type stores like S3. ↳ Now uses a path such as v1/a/b/c/d/e/[sha1] instead of /[sha1] alone. This helps MinIO, which uses the file system to store objects directly, resulting in a very large folder in XFS, which is not at all ideal for file system operations.

Others

• BM-21651: Fix: Errors in SBOM generated for v5.2.0.
• HikariCP version upgrade to 7.0.2.
