Yesterday I "blurbified" the 2.7, 3.6, and master branches in CPython.
It's finally official: all* branches have now been "blurbified". This
means that Misc/NEWS is no longer present in any of CPython's active
branches. Instead, Misc/NEWS has been broken up into a zillion little
files in the new Misc/NEWS.d directory tree. (Misc/NEWS can be
reconstituted consistently from this directory tree.) This banishes
forever the annoying problem of Misc/NEWS merge conflicts when you
attempt to merge a pull request, when release managers create a release,
etc.
We announced "blurb" a month or two back, and you should already be creating your news entries in Misc/NEWS.d. But just in case, here's a quick refresher.
The core-workflow team has created a tool called "blurb" that makes it easy to create a news entry for a commit. It's easy to install and use.
You can install it with:
python3 -m pip install blurbIt requires Python 3.5 or newer. (Sorry, it can't get backported to 3.4 without fixing a bug in "re"... and 3.4 is closed for bugfixes.)
To create a news entry, just run blurb from anywhere inside your CPython repo. On POSIX systems just make sure "blurb" is on your path, then simply run "blurb". On Windows the recommended method is "python3 -m blurb".
When you run blurb, it'll guide you through creating a news entry. It'll pop open an editor window on a template. Just modify the template as needed, write your news entry at the bottom, and save and exit. blurb will write out your news entry as a uniquely-named file in Misc/NEWS.d--and even stage it for you in "git"!
If for some reason you want to create news entries by hand, or if you just want more information, please see the Dev Guide:
https://devguide.python.org/committing/#what-s-new-and-news-entriesand the documentation for blurb on PyPI:
https://pypi.org/project/blurb/The migration to Misc/NEWS.d and blurb has a few other implications:
- Existing pending PRs or patches with Misc/NEWS entries will need to be updated to generate the entry with blurb. (Again, there really shouldn't /be/ any by this point.)
- If you want to read a branch's NEWS entries in a convenient format, simply use "blurb merge" to produce a temporary NEWS file. (But don't check it in!) See the blurb documentation.
- As part of the release process, release managers now use blurb to merge all the individual NEWS.d/next files into a single NEWS.d file for that version. They'll also build a traditional monolithic Misc/NEWS included in the release's source tarball (but this won't get checked in).
- If you're building 3.x docs from a cpython git repo, you'll now need to have blurb installed. You can use the "make venv" recipe in Doc/Makefile to create a python3 venv with blurb and sphinx.
Happy blurbing!

- All except 3.3. Ned Deily has taken over as release manager of 3.3, and he thinks we shouldn't bother with blurbifying that branch--it'll reach end-of-life in mere weeks, and we're only going to make one more release of it, and it gets very little work done these days.
p.s. Thanks to Ned Deily who originally wrote this email, which I hacked up and sent.
