In the release notes there is a whole chapter on SQL Language
Enhancements. For this feature, p42-43. It was introduced in Firebird 1.0.

Try:

C:\Program Files\Firebird\Firebird_1_5\doc

Or you can download the release notes individually. If you have not
yet taken the chance to read them, it is time well spent.
