Fixes:

• Refactor and fix crash with TempSpace class. RS-219036.
• Crash on parsing an invalid section in directories.conf. RS-219756.
• Fix server hang when trying to stop a server with active connections with event notifications. RS-206648.
• Add an extra check during jump nodes validation. RS-209398.
• Remove write permission check for GSS lib and GSS key parameters (read is enough). RS-209956.
• Mark only old statements as updated in aggtrace. RS-216145.
• Fix incorrect maximum size when reading dbb parameter values in SHOW DATABASE. RS-215490.
• Don't throw an exception during mapping if the regular expression in the USER part can't be processed. RS-211221.
• Hang when opening shared memory file. FB-8416.
• Release mutex via activeThreadGuard pointer, not the optional one (threadGuard instead of dummyGuard for crypto thread). FB-8414.
• Fix potential deadlock when starting the encryption thread. FB-8403 B3_0_Release backport. FB-8412.
• Remove config parameters values printing in security measures. RS-210560.
• Get HINSTANCE to correctly initialize root prefixes for determining the path to executable/dll before getting MemoryWipePasses from config. RS-196872.
• Remove redundant plugin reload on super server, update it only on classic after stateLock ast. FB-8393.
• Add missing mergeStats in garbage collector and cache writer threads. FB-8392.
• Put auth block for migartion connection. RS-211093.

• Backport fix use :@ characters and add sub-section to configure username and password for replica_database. RS-200912.

• Add pointers tree to TempSpace. RS-185051.

Improvements:

• Allow use of dash ('-') in SIMILAR TO pattern outside of character classes. RS-195027.
• Aggregate transactions in aggtrace. RS-202832.
• If BugcheckAbort is enabled, a dump will be created when an index corruption is detected.
