On behalf of the IronPython team, I'm very happy to announce the release of IronPython 3.4.0-beta1. The runtime targets are .NET Framework 4.6, .NET Core 3.1 and .NET 6. The baseline for this release is Python 3.4.
IronPython 3.4 uses Python 3.4 syntax and standard libraries and so your Python code will need to be updated accordingly. For details on upgrading from IronPython 2 to 3 see the Upgrading from IronPython 2 to 3 article.
While compatibility with CPython has been one of our main goals with IronPython 3, there are still some differences that may cause issues, for more information see the Differences from CPython article.
This release brings in numerous bug fixes, improvements and features from newer versions of Python. Notably:
- int/long unification (thanks @BCSharp )
- f-string support (from 3.6)
- % formatting for bytes (from 3.5)
- improved module support (for example venv, ensurepip on Linux, django, typing)
- improved test coverage
- improved compatibility with CPython
Thanks to @BCSharp for the numerous contributions!
