Fixes:

• Crash on releasing timer during server halt. RS-74745.
• Shutting down idle LDAP connections uses time() instead of a timer, which should eliminate the crash during server halts. RS-73290.
• On ARM64 architecture, DWARF-2 debug information format is used.
• Memory corruption caused by "inline" operator "delete".
• After multifactor authentication and policy handling, cached connections to the security database are terminated. RS-74745.
• Fixed LDAP role lookup for users having parentheses in their DNs. RS-35932.
• LDAP session initialization is protected by critical section. This shoud elliminate a possible crash during multi-threaded initialization. RS-70970.
• Errors in "ON DISCONNECT" triggers are outputt o trace if the log_errors parameter is set.
• Refactored binding of the sort buffers to their owners. That should fix memory corruption when releasing sorts. RS-73597.

Improvements:

• LDAP error diagnostics have been improved.
