You might want to clarify what you mean with 'licensed', technically
most (if not all) software is licensed, even if it is free.

That is unanswerable. If you look at the release notes of Firebird 2.0,
2.1 and 2.5 there are some changes that might break compatibility, but
that highly depends on what your code does. You are the only one who can
answer that by studying the release notes and your source code, or by
testing your application against a higher version of Firebird.

What do you mean with 'licensing issue' and 'licensing thing'? As most
software Firebird has a license, however Firebird is free and in most
respects you can do whatever you want with it (within the confines of
the license).
