Version 0.2.1 (2020-06-18)

  • Fixed an issue where the C implementation of ZoneInfo.__init_subclass__ was not a classmethod, causing errors when attempting to subclass ZoneInfo (GH-82, GH-83).

Version 0.2.0 (2020-05-29)

  • Added support for PyPy 3.6 (GH-74); when installed on PyPy, the library will not use the C extension, since benchmarks indicate that the pure Python implementation is faster.

Version 0.1.0 (2020-05-26)

This is the first public release of backports.zoneinfo. It contains all the features from the zoneinfo release in Python 3.9.0b1, with the following changes:

  • Added support for Python 3.6, 3.7 and 3.8 (GH-69, GH-70).

  • The module is in the backports namespace rather than zoneinfo.

  • There is no support for compile-time configuration of TZPATH.

  • Fixed use-after-free in the module_free function (bpo-40705, GH-69).

  • Minor refactoring to the C extension to avoid compiler warnings (bpo-40686, bpo-40714, CPython PR #20342, GH-72).

  • Removed unused imports, unused variables and other minor de-linting (GH-71).
