I think that this fix should be applied also in 2.7 branch.

ssl_version is a class attribute so you can simply set that before
instantiating FTP_TLS class:
import ftplib
ftplib.FTP_TLS.ssl_version = ...
client = ftplib.FTP_TLS(...)
...

I know that, but it seems pretty unusual. And I would never had guessed from
the documentation, I had to read the source.
My point is that it should be easier to just connect to a TLSv1.2 server: the
documentation should mention the fact that ssl_version is a class

Well, because the ssl_version parameter should have a purpose. If it doesn't,
the least we could do is remove it from the docs.

The only way to establish a successful connection is to pass a custom SSL
context to the constructor.
Why don't you do just that?

New submission from varde:
When trying to connect to a server which only supports TLS version 1.1 or 1.2,
the following error is raised:
ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:598)
For some reason, the SSL version is set to ssl.PROTOCOL_TLSv1 before
