I've been playing around with this build and found a couple very minor things.
I installed it on top of a b10 build that had been freshly installed.
I saw in the release notes that the texture packing generation template TempJson* was removed, but I still see them in my template list when I open the generate sprite sheet dialog. (no biggy, maybe because I didn't do a clean install?)
I installed my texture packer application in a different (non-default) directory and am prompted almost every time for it's location when I need generate a new spritesheet. I think it asks the first time you open spriter, but it does not remember the location once closed.
When saving a spritesheet, I clicked the browse button to navigate to the directory from where I would save the file. If I cancel, it clears out whatever value was in that output file name line edit. If I browse to a directory that has a folder with the same name I chose to name the file and then I click the save button, it opens that directory instead of saving. Example, the directory I am navigated to has a Boss folder and I type 'boss' into the filename field (intending to make a boss.tps file). I click the Save button. Instead of saving the dialog navigates into the Boss folder.
