In your commit log, you can remove:

- Regular bug-fix release

As you already have the full changelog below

For the following :

- Rename ft-index to PerconaFT

There's no mention/context of what in the port changed

Perhaps something like:

- Re-patch files due to path change in WRKSRC

commit log mentions:

databases/mariadb100-server

but there are changes to both client/server

Try:

databases/mariadb100-{server,client}:

TLDR: The summary should match the changes
