Re: 10.2.7 and xtradb in changelog


I don't find this extremely confusing (if it's a change to the code, it's not weird to see it in the changelog; filtering out things exposes us to bugs in the filtering process, which may hide important information) but I think that there is another confusing part. In this page:

I read:
"Note, we still consider incorporating XtraDB optimizations, but as patches, rather than XtraDB as a whole"

But then, it is not clear what exactly is or is not in MariaDB's InnoDB. Percona has a nice list of features:

It would be useful to have a list of which changes are applied to MariaDB's InnoDB. Hope it is not too hard to maintain.

 I agree that it's confusing, but what can we do?

 at least some filters make sense because things like
