[ase-users] New stable release: ASE-3.10

[Jens Jørgen Mortensen]

Hi!

ASE version 3.10 has been released.  Many bugs have been fixed since 
version 3.9 from June last year and some of the new features are listed 
here:

**IMPORTANT change**: We want people to convert their old trajectory 
files (based on Python's pickle protocol) to the new file format that 
was introduced in 3.9.  If you try to read an old file with version 
3.10, it will refuse to do so and tell you how to convert the file.  The 
conversion is easy and described here:

ASE works really well on Python 3 now.  I have started to use Python 3.4 
for all my work, but I don't use all corners of ASE.  Therefore, I would 
like some more users and developers to give Python 3 a try so that we 
can find the remaining bugs.

Thanks to everyone who contributed!

Please upgrade and report any problems you run into.
