Thank you Fabiano for your reply.
I have checked the release notes you have suggested.
However, I am still not able to find any information on the
performance speed comparisons between the two versions: 2.0.5 and 2.1.2.

Are you aware of any speed advantage when using version 2.1.2 with
Delphi 7 applications (standard range of queries, not using any
advanced database features offered by version 2.1.2), as compared to
the older version 2.0.5 ?

There must be a reason why Firebird continues to maintain two parallel
versions (2.0.x and 2.1.x), not to mention the old series 1.5.x.
I would like to see some proper information provided by the developers
why they are maintaining and offering all these different versions of
Firebird ??
All this range of versions and options is simply confusing.

Regards
Mario
