Re: Updating 1.2.8 and Template Pack
Nothing has been changed in bp-default theme from Buddypress 1.2.7 to 1.2.8. You can see changes have been made only to core files here:
https://trac.buddypress.org/changeset?old_path=%2Ftags%2F1.2.7&old=3570&new_path=%2Ftags%2F1.2.8&new=4078
If you’re unsure about updating, keep a copy of BP1.2.7 handy so you can revert back to it if anything breaks
