Please review the attached news item. This is intended as a head-up
before I adjust the default PYTHON_TARGETS setting in our profiles.

Any improvements are welcome.

Title: Python 3.4 enabled by default
Author: Mike Gilbert <floppym@gentoo.org>
Content-Type: text/plain

Revision: 1
News-Item-Format: 1.0

Python 3.4 will be enabled by default soon, replacing Python 3.3 as the
default Python 3 interpreter.

PYTHON_TARGETS will be adjusted to contain python2_7 and python3_4.
PYTHON_SINGLE_TARGET will remain set to python2_7 for the time being.

If you have PYTHON_TARGETS set in make.conf, that setting will still be
respected. This change only affects the profile defaults.

At the same time, support for Python 3.2 will be removed from the
python-r1 family of eclasses. This version no longer receives regular
bug fixes, and is currently only receiving security updates.

Once the changes have taken place, a world update should take care of
reinstalling any python libraries you have installed. You should also
switch your default python3 interperter using eselect python, and
possibly run python-updater if you have some older python libraries
installed.

Expect these changes to take place around one week from the date of
this news item.

s/soon/on YYYY-MM-DD/ :). You'll fill in the date when you commit it.

I would emphasize that this is about 'the default values'.

I think you could suggest that the user may want to adjust it manually.

You may want to mention --changed-use. Also, I don't think
python-updater is relevant here since python.eclass doesn't support
3.4.

Yay, thanks for working on this!

I agree with all the things Michał pointed out.

Also, you have the non-word interperter in there. :)

Cheers,

Dirkjan

Thanks for the feedback; I forgot that we don't support 3.4 in the old eclass.

Here's version 2.

Python 3.4 will be enabled by default on 2014-11-22, replacing
Python 3.3 as the default Python 3 interpreter.

PYTHON_TARGETS will be adjusted to contain python2_7 and python3_4 by
default via your profile.

PYTHON_SINGLE_TARGET will remain set to python2_7 by default.

If you have PYTHON_TARGETS set in make.conf, that setting will still be
respected. You may want to adjust this setting manually.

At the same time, support for Python 3.2 will be removed from the
python-r1 family of eclasses. This version no longer receives regular
bug fixes, and is currently only receiving security updates.

Once the changes have taken place, a world update should take care of
reinstalling any python libraries you have installed. You should also
switch your default python3 interperter using eselect python.

For example:

eselect python set --python3 python3.4
emerge -uDv --changed-use @world

And version 3, with the spelling mistake fixed (thanks djc).

Problem: Gentooers are conditioned to consider -r1 a version indicator, 
making "python-r1" the closest back-reference to which "This version" can 
refer.  At least here that was rather confusing, because on first parse 
it looked as if python-r1 (the eclass family) is only getting security 
updates, in which case why is python 3.2 being removed from it?

Solution: Make explicit that it's python 3.2 that is security-update only.

One possible rewrite (which also changes the order quite a bit and with 
it the emphasis, don't know if that's desired but it appears to do the 
job from here):

Python 3.2, now security-update-only as it's nearing end-of-life, will be 
dropped from the python-r1 family of eclasses at the same time.

It would be easier to just restate "Python 3.2" as the subject of the
second sentence.
