Hi!
On the official python site, it is possible to download python 3.4.4 here:
https://www.python.org/downloads/release/python-344/
There are binary installation files for Windows. But Python 3.4.4 is two
years old. There is 3.4.7 that was just released, but there are no
binaries.

To answer my own question:
- You can convert a firebird 1.5 database into 2.5 with this tool:

- You can install firebird 2.5 instead of 1.5. Old BDE based program
will still work with it, because the Firebird 2.5 server can talk with a
1.5 c

False
The most commonly used objects don't define equality as identity, e

Your footnote for [1] appears to be missing. What's a hash consing set? It
appears to be nothing more than frozen sets which you put in a cache so as to

Python 3.4 is now in "security fixes only" mode. This is the final
stage of support for Python 3.4. Python 3.4 now only receives security
fixes, not bug
