I took a look at 1.5.4 - the manifest was missing the version
information in the firebirdsql-full.jar again? Thought this was
fixed in 1.5.1?

Also - once you get that fixed it would be helpful to include the
entire build number (not just major.minor.0) - Build 1.5.1
had "Implementation-Version: 1.5.0JDK_1.4 .." which was not correct -
should have read "Implementation-Version: 1.5.1JDK_1.4 ...".

This information is very helpful for reporting bugs and just know
which build is in use!

Thanks,

Ron
