Subject Re: [DISCUSS] DB upgrade issue workaround for 4.10.0.0 users upgrading to 4.11.0.0
Date Wed, 14 Feb 2018 16:26:29 GMT
Rene,

The issue is certainly not due the git workflow but to upgrade schemes we
have.

The result of this workflow for us is that it is easier to find to which
branches a particular commit is added as by merging forward the commit id
of the actual fix doesn't change. so instead of looking in each branch for
a bit of code you can look for a commit id on a branches log.
