The old one was not properly maintained and is now deprecated. The new

As discussed in id:871udhcmks.fsf@zancas.localnet, notmuch-vim doesn't
really meet the standards of the CLI, emacs interface, or python
bindings in terms of being well maintained.
There should be no functional changes, except that you don't need to
make the directories before installing.
