No. they are separate downloads.
In previous versions, the user was limited to the palettes and borders included in the release, because border names and palettes were hardcoded into the executable. Now they aren't hardcoded anymore, so the user can add and remove palettes and borders, or he can create their own ones.
Note: i've changed the format of the borders and some paths, so old stuff don't work anymore.
If you were using an older version of Ohboy, you should delete it before installing this one.
If you were using an older OPK version of ohboy, you should delete the OPK file and the "$HOME/.config/ohboy/" folder. (new release stores things in "$HOME/.ohboy/" instead).
