+Command-Line Interface
+----------------------
+
+Stopped `notmuch dump` failing if someone writes to the database
+
+ The dump command now takes the write lock when running. This
+ prevents other processes from writing to the database during the
+ dump which would cause the dump to fail. Note, if another notmuch
+ process already has the write lock the dump will not start, so
+ script callers should still check the return value.
+
+`notmuch insert` requires succesful message indexing for success status
+
+ Previously the `notmuch insert` subcommand indicated success even if
+ the message indexing failed, as long as the message was delivered to
+ file system. This could have lead to delivered messages missing
+ tags, etc. `notmuch insert` is now more strict, also requiring
+ succesful indexing for success status. Use the new `--keep` option
+ to revert to the old behaviour (keeping the delivered message file
+ and returning success even if indexing fails).
+
+`notmuch insert` has gained support for `post-insert` hook
+
+ The new `post-insert` hook is run after message delivery, similar to
+ `post-new`. There's also a new option `notmuch insert --no-hooks` to
+ skip the hook. See the notmuch-hooks(1) man page for details.
+
+`notmuch search` now supports `--duplicate=N` option with `--output=messages`
+
+ Complementing the `notmuch search --duplicate=N --output=files`
+ options, the new `--duplicate=N --output=messages` combination
+ limits output of message IDs to messages matching search terms that
+ have at least `N` files associated with them.
+
+Emacs Interface
+---------------
+
+Use the `j` key to access saved searches from anywhere in notmuch
+
+ `j` is now globally bound to `notmuch-jump`, which provides fast,
+ interactive keyboard shortcuts to saved searches. For example,
+ with the default saved searches `j i` from anywhere in notmuch will
+ bring up the inbox.
+
+Expanded default saved search settings
+
+ The default saved searches now include several more common searches,
+ as well as shortcut keys for `notmuch-jump`.
+
+Improved `q` binding in notmuch buffers
+
+ `q` will now bury rather than kill a notmuch search, show or tree
+ buffer if there are multiple windows showing the buffer. If only a
+ single window is showing the buffer, it is killed.
+
+Library changes
+---------------
+
+Introduced database version 3 with support for "database features."
+
+ Features are independent aspects of the database schema.
+ Representing these independently of the database version number will
+ let us evolve the database format faster and more incrementally,
+ while maintaining better forwards and backwards compatibility.
+
+Library users are no longer required to call `notmuch_database_upgrade`
+
+ Previously, library users were required to call
+ `notmuch_database_needs_upgrade` and `notmuch_database_upgrade`
+ before using a writable database. Even the CLI didn't get this
+ right, and it is no longer required. Now, individual APIs may
+ return `NOTMUCH_STATUS_UPGRADE_REQUIRED` if the database format is
+ too out of date for that API.
+
+Library users can now abort an atomic section by closing the database
+
+ Previously there was no supported way to abort an atomic section.
+ Callers can now simply close the database, and any outstanding
+ atomic section will be aborted.
+
+Add return status to notmuch_database_close and
+notmuch_database_destroy
+
+Bug fixes and performance improvements for thread linking
+
+ The database now represents missing-but-referenced messages ("ghost
+ messages") similarly to how it represents regular messages. This
+ enables an improved thread linking algorithm that performs better
+ and fixes a bug that sometimes prevented notmuch from linking
+ messages into the same thread.
+
+nmbug
+-----
+
+The Perl script has been translated to Python; you'll need Python 2.7
+or anything from the 3.x line. Most of the user-facing interface is
+the same, but `nmbug help` is not `nmbug --help`, and the following nmbug
+commands have slightly different interfaces: `archive`, `commit`,
+`fetch`, `log`, `pull`, `push`, and `status`. For details on the
+new interface for a given command, run `nmbug COMMAND --help`.
+
+nmbug-status
+------------
+
+`nmbug-status` can now optionally load header and footer templates
+from the config file. Use something like:
+
+ {
+ "meta": {
+ "header": "<!DOCTYPE html>\n<html lang="en">\n...",
+ "footer": "</body></html>",
+ ...
+ },
+ ...
+ },
+
+Python Bindings
+---------------
+
+Add support for `notmuch_query_add_tag_exclude`
+
+Build System
+------------
+
+The notmuch binaries and libraries are now build with debugging symbols
+by default. Users concerned with disk space should change the
+defaults when configuring or use the strip(1) command.
+
+Notmuch 0.18.2 (2014-10-25)
+===========================
+
+Test Suite
+----------
+
+Translate T380-atomicity to use gdb/python
+
+ The new version is compatible with gdb 7.8
+
+Emacs 24.4 related bug fixes
+
+ The Messages buffer became read-only, and the generated mime
+ structure for signatures changed slightly.
+
+Simplify T360-symbol-hiding
+
+ Replace the use of `objdump` on the object files with `nm` on the
+ resulting lib.
+
+Notmuch 0.18.1 (2014-06-25)
+===========================
+
+This is a bug fix and portability release.
+
+Build System
+------------
+
+Add a workaround for systems without zlib.pc
+
+Make emacs install robust against the non-existence of emacs
+
+Put notmuch lib directory first in RPATH
+
+Fix handling of html_static_path in sphinx
+
+ Both the python bindings and the main docs had spurious settings of
+ this variable.
+
+Test Suite
+----------
+
+Use --quick when starting emacs
+
+ This avoids a hang in the T160-json tests.
+
+Allow pending break points in atomicity script
+
+ This allows the atomicity tests to run on several more architectures/OSes.
+
+Command-Line Interface
+----------------------
+
+To improve portability use fsync instead of fdatasync in
+`notmuch-dump`. There should be no functional difference.
+
+Library changes
+---------------
+
+Resurrect support for single-message mbox files
+
+ The removal introduced a bug with previously indexed single-message
+ mboxes. This support remains deprecated.
+
+Fix for phrase indexing
+
+ There were several bugs where words intermingled from different
+ headers and MIME parts could match a single phrase query. This fix
+ will affect only newly indexed messages.
+
+Emacs Interface
+---------------
+
+Make sure tagging on an empty query is harmless
+
+ Previously tagging an empty query could lead to tags being
+ unintentionally removed.
+
+Notmuch 0.18 (2014-05-06)
