🐍 Python 3 Support
--------------------
🐍 Python 2
-----------
Python 3 support has been introduced starting with Tahoe-LAFS 1.16.0, alongside Python 2.
System administrators are advised to start running Tahoe on Python 3 and should expect Python 2 support to be dropped in a future version.
Please, feel free to file issues if you run into bugs while running Tahoe on Python 3.
Python 3.7 or later is now required.
If you are still using Python 2.7, use Tahoe-LAFS version 1.17.1.
