commit 96678bc includes mappings for H and L, which now override the preexisting mappings in .vimrc.
The pre-existing mappings allowed you to navigate among your tabs quickly with H and L.
The new mappings take you to the start and end of the line you're on. ^ or 0 and $ already did that, so my preference would be to remove the new mappings.
Pre-existing mappings (still there, just non-functional now):
if !exists('g:spf13_no_fastTabs')
map <S-H> gT
map <S-L> gt
endif
New mappings:
"go to first and last char of line
nnoremap H ^
nnoremap L g_
vnoremap H ^
vnoremap L g_
