Monday, April 20, 2020Python 2.7.18, the last release of Python 2The CPython core developers are pleased to announce the immediate availability of Python 2.7.18.

Python 2.7.18 is the last Python 2.7
release and therefore the last Python 2 release. It's time for the CPython
community to say a fond but firm farewell to Python 2.

Python 2.7 has been under active development since the release of Python 2.6,
more than 11 years ago. Over all those years, CPython's core developers and
contributors sedulously applied bug fixes to the 2.7 branch, no small task as
the Python 2 and 3 branches diverged. There were large changes midway through
Python 2.7's life such as PEP 466's feature backports to the ssl module and
hash randomization. Traditionally, these features would never have been added
to a branch in maintenance mode, but exceptions were made to keep Python 2 users
secure. Thank you to CPython's community for such dedication.

Python 2.7 was lucky to have the services of two generations of binary builders
and operating system experts, Martin von Löwis and Steve Dower for Windows, and
Ronald Oussoren and Ned Deily for macOS. The reason we provided binary Python
2.7 releases for macOS 10.9, an operating system obsoleted by Apple 4 years ago,
or why the "Microsoft Visual C++ Compiler for Python 2.7" exists is the
dedication of these individuals.

Python 3 would be nowhere without the dedication of the wider community. Library
maintainers followed CPython by maintaining Python 2 support for many years but
also threw their weight behind the Python 3 statement.
Linux distributors chased Python 2 out of their
archives. Users migrated hundreds of millions of lines of code, developed
porting guides, and kept Python 2 in their brain while Python 3 gained 10 years
of improvements.

Finally, thank you to GvR for creating Python 0.9, 1, 2, and 3.

Long live Python 3+!
Python2.7.18是Python2.7的最后一个发行版,也是最后一个Python2发行版。是时候对Python 2说一声亲切而坚定的告别了。
