Update versions

[Giovanni Giazzon]

Hi all,
my problem is that I want to update an existing version. For each deploy we
have a version, but sometimes bugs show up and we have to update these
versions. It is possible to update versions? I know that I can't commit on
versions and the only solution seems to create a new branch of this version
and update it. But I was looking for another possibility, without new
branches.
 
Thanks for the help.
