#2* at the end of 2019
I guess it's due -- Python 3 finally has some improvements to the runtime that I think will start to pull more Python2 people over.

#3Good to see that it will be a quiet transition. Linus would approve.

#4How dedicated to keep it going so long! Maintenance this long-term is a time-sucking activity.

Their plan is more nuanced than "at the end of 2019". From a numpy feature standpoint, it's EOY 2018, bugs through EOY 2019:
> Until December 31, 2018, all NumPy releases will fully support both Python2 and Python3.
Starting on January 1, 2019, any new feature releases will support only Python3.
The last Python2 supporting release will be designated as a long term support (LTS) release, meaning that we will continue to merge bug fixes and make bug fix releases for a longer period than usual. Specifically, it will be supported by the community until December 31, 2019.

#6At the SciPy 2017 conference, for the first time I saw speakers who were presenting new libraries say that they were not going to be developing Python2 versions. Quite a change from a year or two ago.

#7That’s about the same time python 2 support drops in general. Sounds strange to support packages after the underlying python has moved on.
Kudos to the numpy team for writing the most awesome python module under the sun, and for providing great support!

All my libraries have been py3-only since around last year. I'm also not caring much about supporting 2 on the old ones I maintain. 2 is pretty old, it's time to move on.

#9It would be interesting to see whether Python 2 is the longest supported major version for a programming language.

#10Good. The glacial migration from Python 2 to 3 is one of the worst things about an otherwise fantastic ecosystem. The tide is turning though, with Django having already dropped support for 2, and now with Numpy too hopefully Python 2 can be properly consigned to the history books.
For people wondering why it's been like this for almost a decade(!) since Python 3.0 was released: Python 3.0 was actually terrible. It lacked many critical things, and was riddled with bugs and security flaws until 3.3, which was released 4 years after 3.0. This cemented in many people's minds the idea that Python 3 was a bad thing. Python 2 was and is a fantastic programming language, so it was a very high bar to move up from. Python 3 has come a long way since then, Python 3.6 is now a decent step up from 2.7.
