It's been added to CustomBuild 2.0, now available on files1.
The changes are quite messy, as they've changed both the naming format from:
- "MySQL-server" to "mysql-community-server"
- from "linubx2.6" to "el6" or "el7"
- frrom 32-bit "i386" to "i686"
and it all varies depending on version.. so 5.5.53 is old, 5.5.58 is the new format.
Same sort of mess for 5.6.
Note, we've added 5.7 support now.
------------
Note! for ALL of the above versions, it will only work with CustomBuild 2.0.
Handling the mess of if-then-else statements in CustomBuild 1.2 or 1.1 was not done.
1.x is essentially end-of-life now anyway.
