GC3Pie 2.5.3 has been released

[Riccardo Murri]

Dear GC3Pie users,

We are proud to announce release 2.5.3 of GC3Pie. This is
a bugfix release; noteworthy changes from 2.5.2 include:

* Use `~/.gc3/gc3pie.log.conf` for configuring logging.
GC3Utils still continue to use the `gc3.gc3utils` logger and the
logging configuration file `~/.gc3/gc3utils.log.conf`.

* Allow submitting jobs which request exactly the max amount of memory.

Previously, the SLURM backend would add 1MB to every request, to
ensure that rounding requests of less <1MB resulted in a 0MB request.
However, this ended up in jobs that request exactly the amount of
available memory not being accepted by `sbatch`, since they request
1MB more than available...

Now all backends respect the request, converting into MBs and rounding
off towards 0, but never asking less than 1MB.

Yours,
the GC3Pie development team

Dear GC3Pie users,

We are proud to announce release 2.6.0 of GC3Pie.

With this release, GC3Pie becomes compatible with Python 3,
without changing its programming API (hence the release number
only records this as a "minor" change).

Porting to Python 3 has been no small endeavour, and much of the
grunt work has been done by the fantastic tool `futurize` [1], whose
authors I would like to wholeheartedly thank :-) I would also like to extend
my gratitude to Sergio Maffioletti, Lars Malmstroem, and Kenneth Hoste
who tested pre-release code and reported a number of bugs and issues.

Release series 2.6.x is quite likely the last to include support for Python 2.6;
future release series will require Python 2.7 or Python 3.5+.

Additional information is available from the NEWS file [2] and,
as always, through:

* the GC3Pie documentation website: http://gc3pie.readthedocs.io/
* the mailing-list: gc3...@googlegroups.com
