A previously requested API change is that `notmuch_database_reopen` is
now exposed (and generalized).
+The previously severe slowdowns from large numbers calls to
+notmuch_database_remove_message or notmuch_message_delete in one
+session has been fixed.
+
As always, the canonical source of API documentation is
`lib/notmuch.h`, or the doxygen formated documentation in `notmuch(3)`
The `notmuch config set` subcommand gained a `--database` argument to
specify that the database should be updated, rather than a config file.
+The speed of `notmuch new` and `notmuch reindex` in dealing with large
+numbers of mail file deletions is significantly improved.
