Please upgrade to 2.2 here.
The 2.0 and 2.1 branches are no longer being updated.
I find the new location of the post button being to the right completely in the wrong place. I just downloaded a new version of garden, haven't done so in a while, and went to make a post and just instinctively clicked save draft as i assumed that would be where post discussion should be. It seems as if they should be the other way round, we read from left to right so the button with the higher precedence should be at the left.
