Hi Sergei,
Appreciate you considering other options. Unfortunately in this case it seems Percona did not release a new 5.6 version in time for this 10.1.25 merge.
However, interestingly, they did tag a release for 5.7.18-15 in the PerconaFT repository (which is common to both 5.6 and 5.7) in late May, that did include the fix I wanted :)
Percona tells me that they will only be doing a 5.6 release once Oracle releases 5.6.37, which could be quite some time (plus the time for Percona to do their thing).
Is there potentially a way to deal with this, e.g. accept any tagged release from PerconaFT (be it 5.6 or 5.7 .. but perhaps use a different versioning indicator for consistency)
I have a feeling that similarly to MariaDB 10.1 only getting quarterly release from now on, Percona 5.6 is probably not going to get as regular attention as 5.7.
For example, this year, PerconaFT has had 5 tags for 5.7, but only 3 for 5.6.
Thanks,
Phil
