My dear Artem,
It is more difficult to explain to customers that it is necessary to go back (it is an acknowledgment of failure) than to tell them to wait, that the problem is known and that it will be solved.
Only a blocking bug can justify a reversal, here this is not the case.
It is impossible to go back because customers use now the Version History for Blog Posts, Feature that was long awaited.
If you can't give a date, which we can accept, say it frankly, it's better than proposing a solution that isn't one.
I will announce 3 weeks to my customers because it is about the average release of the GridBox versions
This post is closed for me. Don't waste time answering me.
Thanks for all.
Claude
