 +Notmuch 0.26 (UNRELEASED)
 +=========================
 +
 +Test Suite
 +----------
 +
 +Out-of-tree builds
 +
 +  The test suite now works properly with out-of-tree builds, i.e. with
 +  separate source and build directories. The --root option to tests
 +  has been dropped. The same can now be achieved more reliably using
 +  out-of-tree builds.
 +
 +Encrypted Mail
 +--------------
 +
 +Indexing cleartext of encrypted e-mails
 +
 +  It's now possible to include the cleartext of encrypted e-mails in
 +  the notmuch index.  This makes it possible to search your encrypted
 +  e-mails with the same ease as searching cleartext.  This can be done
 +  on a per-message basis with the --try-decrypt argument to indexing
 +  commands (new, insert, reindex), or by default by running "notmuch
 +  config set index.try_decrypt true".
 +
 +  Note that the contents of the index are sufficient to roughly
 +  reconstruct the cleartext of the message itself, so please ensure
 +  that the notmuch index itself is adequately protected.  DO NOT USE
 +  this feature without considering the security of your index.
 +
+ Notmuch 0.25.2 (2017-11-05)
+ ===========================
+ 
+ Command Line Interface
+ ----------------------
+ 
+ Fix segfault in notmuch-show crypto handling when compiled against
+ GMime 2.6; this was a regression in 0.25.
+ 
+ General
+ -------
+ 
+ Support for GMime before 3.0 is now deprecated, and will be removed in
+ a future release.
