Python 3.8 was released on October 14th, 2019.
- Added 'Programming Language :: Python :: 3.8' trove classifier.
- Added 'py38' to the tox test matrix.
- Added 'python: 3.8' to the Travis test matrix.
- Removed 'dist: xenial' from Travis configuration; it is now the
default.
- Removed 'dist: trusty' from Travis configuration; it is not longer
necessary.
- Removed 'sudo' from Travis configuration; it is deprecated.

The use_pydatetime configuration option has been removed. Now, always
default to Python's builtin datetime. mxDatetime support continues to be
available as an alternative to Python's builtin datetime.
distutils is not recommended for use and unnecessary for modern Python
environments. Use only setuptools instead. From
https://docs.python.org/3/library/distutils.html:
> Most Python users will not want to use this module directly, but
> instead use the cross-version tools maintained by the Python Packaging
> Authority. In particular, setuptools is an enhanced alternative to
> distutils ...
>
> The recommended pip installer runs all setup.py scripts with
> setuptools, even if the script itself only imports distutils. Refer to
> the Python Packaging User Guide for more information.
The idea is to release a package 'psycopg2-binary' to allow installing
binary, and leave the psycopg2 package to be source only, to avoid
pushing the unreliability of the wheel pacakge by default (see issue #543).
Version number bumped to test with new packages.
Make all library code compatible with both Python 2 and Python 3. Helps
move to modern Python idioms. Can now write for Python 3 (with
workarounds for Python 2) instead of the other way around.
In the future, when it is eventually time to drop Python 2, the library
will be in a better position to remove workarounds
Added a very small comparability module compat.py where required. It
includes definitions for:
- text_type -- A type. str on Python 3. unicode on Python 2.
- string_types -- A tuple. Contains only str on Python 3. Contains str &
unicode on Python 2.
For library end users, there is no need to install tests alongside the
package itself. This keeps the tests available for development without
adding extra packages to user's site-packages directory. Reduces the
size of the installed package. Avoids accidental execution of test code
by an installed package.
