Hi, welcome to the Cataclysm version of this thread
* As you have noticed, the new raid bosses have been added already, but the heroic mode detection is still work in progress. The fight validator is also not active yet.
* The new talent detection code is live, poke me if you have a report with unknown specs.
* The shield healing code uses the amount remaining field in the SPELL_AURA_* events now, so the tracking should match any other source exactly for any 4.0+ logs. I haven't manually verified it against other analyzers yet, but it matches the manual count exactly.
* To see which build/feature level the parser is using, check the footer for the version number. v13329 is the 4.0+ parser, v10192 is the previous one with the crit-ticks addition.
That seems to be it for now - the rest is still in the todo queue.
