Hi maoling,

I reformatted your original message, because it was pretty hard to read (all in 
a single line) after Apache converted into plain text. Would you please try to 
send plain text messages by default to avoid the conversion? It might help.

Answers inline.

I don’t feel it too fast. I’m happy to see people willing to work on releases 
and I believe it’s a good thing to speed up ZooKeeper releases. 4 years release 
cycle is not something that we should follow in the future.

The discussion about the next major release is just started and doesn’t mean we 
have to cut tomorrow. Talk about it. Your list of upcoming patches are more 
than welcome, we need to discuss where to fit them.

Friends@Facebook are also working hard to get patches into 3.6.0. We need to 
synchronize with all contributors.

Sure. Awesome list.

I think this should go into 4.0.0 instead if it’s only is design phase 
currently. This is probably true for the rest of patches too: everything which 
already has a PR or close to it can fit into 3.6.0, others should go to 4.0.0.
