Re: [rules-dev] Re: [rules-users] Drools5M3 Issues

one option is to put drools api under a totaly new namespace - org.drools5 instead of org.drools. But I'm not keen to do this, although I know hibernate did it moving to hibernate 3. I'm trying to get a CR out in a week or so, so what ever we decide, we are rapidly running out of time. Mark Mark Proctor wrote: > keithnielsen wrote: >> Ok, >> >> I tried to upgrade from M2 to M3.
