And definitely a revolutionary and not evolutionary step towards the next-gen Ganglia. From a developers point of view I love it. The question is - is this not worth a bump in the major number? - From my adminstrators view (and maybe my advanced age :-) I do not like lrevolutions. So the concerns from my side are: --> Compatibility to pre-2.6 Ganglia. Moving to the new framework will be difficult if to many things have to be changed. The GUIs should not change to much and we need to preserve the historical data. --> Continuation of the 2.5.x series with bug-fixes and [minimal] new features maybe necessary for the near future. anyway, I am looking forward to seeing the new stuff in more action. ===== ------------------------------------------------------ Martin Knoblauch email: k n o b i AT knobisoft DOT de www: http://www.knobisoft.de
