Hi Zd;

Thank you. It's clear now.

We (here in our Company) are doing my own Alpha cicle for my onw
product which is an 20 years old product for the vertical market of
lawyers.

As our developing cicle was too large (30 months, because we are
comming from XBase), we used, in all that while, Firebird versions
2.0.3, 2.1.0, 2.1.1, and we are using 2.5.0 since it was published on
the FirebirdOrg.

From my point of view, Firebird 2.5.0 is the best of all of them.

BTW, if it is possible to contribute in this way, I want to say that
we will enter in a big beta-testing process in the next month, and we
can be good testers of any new beta version of Firebird.

Thank you.

Dany
