Maximiliano Robaina wrote about Python3 fixes for the Firebird Django driver :
I just pushed up a new commit into django-firebird github repository [1] with several python 3 fixes.
If anybody can test it with python 3 and report any issue, it will be appreciated.
Take into account that this improvements are available into github repository, not on PyPI yet. Pull requests are welcome 
FDB release 0.7.2 is out:
http://pypi.python.org/pypi/fdb/0.7.2
Highlights for this release:
ā Python 3 Support (thanks to Philippe Makowski)
ā Support for Distributed Transactions
ā Support for NBACKUP Service
ā Support for Trace Service
And as always, some bugs fixed.
Main target for next version: support for Firebird Events.
Note: Iām really glad that Philippe joined the FDB team, especially to look after Python 3 support (but not only that). Thanks!
