Make a new release soon as the previous one has Python 3 compatibility issues and known-fixed bugs

$ /usr/bin/env python --version
Python 3.9.1

$ ssh2john id_rsa
Traceback (most recent call last):
  File "/usr/bin/ssh2john", line 193, in <module>
    read_private_key(filename)
  File "/usr/bin/ssh2john", line 103, in read_private_key
    data = base64.decodestring(data)
AttributeError: module 'base64' has no attribute 'decodestring'

Same kind of error as for #3345.

$ grep -n decodestring /usr/bin/ssh2john
103:        data = base64.decodestring(data)

It is preset in 1.9.0-jumbo-1 git tag:

https://github.com/openwall/john/blob/a16c8a76259ab870c07e5123c237b1900402d9a6/run/ssh2john.py#L103

But it's fixed in bleeding-jumbo git tag:

https://github.com/openwall/john/blob/07c0f3c6b00e29bedcfd2ef23cd0c8b39888c7be/run/ssh2john.py#L107-L114

tag 1.9.0-jumbo is from May 14, 2019.

So releasing a new version will help fix that bug in distro packages that are mostly using python 3.9 nowadays.

Workaround for distro packager waiting for the new release
