Introduced package manager release PIP 21.0 , used to install additional Python libraries from PyPI and other repositories. The key change in the new release is the end of support for Python 2.7 and 3.5, as well as the end of compatibility with cache entries created by in pip versions separately.
Additionally, you can check new release of the project Pyston 2.1 , which develops a high-performance implementation of the Python language using the LLVM project. The implementation is notable for the use of modern JIT compilation technologies and is aimed at achieving high performance similar to that of traditional system languages such as C ++. Pyston 2 is about 20% faster than stock Python 3.8 when passing the test suite python-macrobenchmarks .
The new release of Pyston includes only fixes and minor improvements to make it easier to use. Unfortunately, the code for the Pyston 2 branch remains unavailable, but ready-made assemblies and empty archive are offered for download with information that the project is still closed (Pyston 1.0 was distributed under the Apache 2.0 license, but after the separation of the project code from Dropbox is no longer published).
