Realm Core v13.9.0

Enhancements

• Enable multiple processes to operate on an encrypted Realm simultaneously. (#1845)

Fixed

• Fix a stack overflow crash when using the query parser with long chains of AND/OR conditions. (#6428, since v11.7.0)
• Changing the log level on the fly would not affect the core level log output (#6440, since 13.7.0)
• SyncManager::immediately_run_file_actions() no longer ignores the result of trying to remove a realm. This could have resulted in a client reset action being reported as successful when it actually failed on windows if the Realm was still open (#6050).
• Fix a data race in DB::VersionManager. If one thread committed a write transaction which increased the number of live versions above the previous highest seen during the current session at the same time as another thread began a read, the reading thread could read from a no-longer-valid memory mapping (PR #6411, since v13.0.0).
• Performing count() on an undefined Query would crash. (#6443, since v13.7.0)

Compatibility

• Fileformat: Generates files with format v23. Reads and automatically upgrade from fileformat v5.

Internals
