Important changes with 4.0.6

4.0.6 is now finally live. Along with it are a small smattering of boomkin changes.

In general:
Moonkin form looses armor bonus, gets 15% damage reduction. Cool, since it should just be spells hitting us in raids anyway.
You'll have more mana as a few things (moonfire/sunfire) cost less mana to cast now.
Planting shrooms is now instant so can be done while moving and they do more damage, very handy for raid AoE damage such as on Cho'Gall.
Starfall is now smarter (won't hit mobs you're not in combat with), except when it bugs (often), and drops more stars more quickly.
Meta gems are fixed, but we also have new ones so who cares. You should now use Burning Shadowspirit Diamond.
If you aren't a LW, enchanting now has an Int to wrist enchant, use it.
The stat priority shifts to move Mastery above crit, as our mastery got a buff, so now the priority is:
int > spirit/hit (to hit cap) > haste > mastery > crit

Really, most of these are minor for us. Our play style is the same, as is our cast priority, we just get a little more out of some of our gear and the new gems.

Also, a note: it appears as if all the glyphs got switched around on the talent tree I had posted before, so here's what you'll want to be using in almost all cases:
Prime: Moonfire, Insect Swarm, Wrath
Major: Starfall, Rebirth...optional last spot as Focus, Monsoon, or Innervate depending on fight.
Minor: Mark of the Wild, Unburdened Rebirth, Dash (all optional, as they don't affect combat, but are often helpful)
Once you reach certain gear levels, and for certain fights, the StarSurge glyph may be good to replace one of the above.
