Major changes in 4.0

Version 3.4 was the last version in the 3.x range. Version 4.0 drops the following modules, as they are insecure:

  • rsa._version133
  • rsa._version200
  • rsa.bigfile
  • rsa.varblock

Those modules were marked as deprecated in version 3.4.

Furthermore, in 4.0 the I/O functions is streamlined to always work with bytes on all supported versions of Python.

Version 4.0 drops support for Python 2.6 and 3.3.
