What's new in this version:

Renamed functions RSA_SIGN and RSA_VERIFY:
- Functions priorly introduced as RSA_SIGN and RSA_VERIFY have been renamed to RSA_SIGN_HASH and RSA_VERIFY_HASH respectively

Session time zone is available via the system context:
- The SYSTEM namespace of the built-in function RDB$GET_CONTEXT has been extended with the SESSION_TIMEZONE parameter that returns the time zone of the current session.

More efficient implementation of SUBSTRING for UTF-8 character set:
- Built-in function SUBSTRING has been improved to provide better performance when called with UTF-8 input strings

Allow replication plugins to refuse the current attachment:
- The replication plugin API has been extended to allow the plugin to validate the attachment and return an error if it refuses to replicate its changes

Immediate execution of DSQL_drop and DSQL_unprepare commands:
- Delayed execution of DSQL_drop and DSQL_unprepare options of the dsql_free_statement() operation has been replaced with an immediate execution in order to release resource locks faster.

Provide time zone ID constants in public headers:
- Time zone IDs used by the Firebird engine have been made available in the header files of the public API

Make RDB$GET_TRANSACTION_CN working the same way in Super and Classic:
- Built-in function GET_TRANSACTION_CN has been fixed to return the same result (proper commit number) for the given transaction number in all architectures. Priorly it might return NULL in Classic Server.
