You heard right, update your clients and love the updates because its just what we asked for! Heres what Notch says he added from his blog, The Word of Notch.
* Working server-side inventory! Finally! (And as a result of that, a whole pile of bugs and issues got fixed) * Made SMP servers save chunks way less often in most cases. Chunks don’t resave if they got saved in the last 30 seconds * Moving too far away from a container, or having it blow up, closes the inventory screen * Fixed /kill * Introduced leaf decay again. It acts differently from before * You can now throw eggs * On a whim, added super exclusive clan cloaks for Mojang Employees * .. and something else, which is even more rare
I don't know whether to be scared or happy about that last one....but I certainly like the leaf decay. Helps out when you are playing a server, find a tree, and no wood; we all have probably had that happen to us. The egg throw seems usefull for fighting zombiepig menand skeleton archers...possibly...tell me how that works out.
