What's new in this version:

- Two new context variables LOCALTIME and LOCALTIMESTAMP that are synonyms for CURRENT_TIME and CURRENT_TIMESTAMP, respectively. They can be used in this sub-release and in Firebird 3.0.4 and later, for forward-compatibility with Firebird 4. See Context Variables LOCALTIME and LOCALTIMESTAMP for details
- A read-only transaction will no longer force write the Header\TIP page content to disk immediately after a change. This improvement gives a significant performance gain where there are numerous light read-only transactions. At this stage, it affects only Superserver. For Classic and Superclassic it is more complex to implement and should appear in Firebird 4.0
- The IP address of the remote host is now appended to error messages in firebird.log for TCP connections
