I meant all the commits in my _git_ local repository for debian/ :)
I admit I didn't make it very clear, sorry.

BTW there's another good reason to hold back 0.147.
Please have a look at this bug report:
https://bugs.launchpad.net/ubuntu/+source/mame/+bug/1063993

I've just realized 0.146-4 is potentially affected by the same issue,
so a new fixed release is strongly recommended IMHO.
I will then sync it in Ubuntu.
