Notmuch 0.9 (2011-10-01)
========================

New, general features
---------------------

### Correct handling of interruptions during `notmuch new`

`notmuch new` now operates as a series of small, self-consistent
transactions, so it can correctly resume after an interruption or
crash.  Previously, interruption could lose existing tags, fail to
detect messages on resume, or leave the database in a state
temporarily or permanently inconsistent with the mail store.

Library changes
---------------

### New functions

`notmuch_database_begin_atomic` and `notmuch_database_end_atomic`
allow multiple database operations to be performed atomically.

`notmuch_database_find_message_by_filename` does exactly what it says.

### API changes

`notmuch_database_find_message` (and `n_d_f_m_by_filename`) now return
a status indicator and uses an output parameter for the
message. This change required changing the SONAME of libnotmuch to
libnotmuch.so.2

Python bindings changes
-----------------------

  - Re-encode python unicode objects to utf-8 before passing back to
    libnotmuch.
  - Support `Database().begin_atomic()/end_atomic()`
  - Support `Database().find_message_by_filename()`
    NB! This needs a db opened in READ-WRITE mode currently, or it will crash
    the python process. The is a limitation (=bug) of the underlying libnotmuch.
  - Fixes where we would not throw NotmuchErrors when we should (Justus Winter)
  - Update for `n_d_find_message*` API changes (see above).

Ruby bindings changes
---------------------

  - Wrap new library functions `notmuch_database_{begin,end}_atomic.`
  - Add new exception `Notmuch::UnbalancedAtomicError.`
  - Rename destroy to destroy! according to Ruby naming conventions.
  - Update for `n_d_find_message*` API changes (see above).

Emacs improvements
------------------

  * Add gpg callback to crypto sigstatus buttons to retrieve/refresh
    signing key.
  * Add `notmuch-show-refresh-view` function (and corresponding binding)
    to refresh the view of a notmuch-show buffer.

Reply formatting cleanup
------------------------

`notmuch reply` no longer includes notification that non-leafnode
MIME parts are being suppressed.
