+Notmuch 0.21 (UNRELEASED)
+=========================
+
+General
+-------
+
+Notmuch now requires gmime >= 2.6.7. The gmime 2.4 series is no longer
+supported.
+
+Database revision tracking: `lastmod:` queries
+
+ Each message now has a metadata revision number that increases with
+ every tagging operation. See the discussion of `lastmod:` in
+ `notmuch-search-terms(7)` for more information.
+
+Notmuch database upgrade to support `lastmod:` queries
+
+ The above mentioned `lastmod:` prefix. This will be done
+ automatically, without prompting on the next time `notmuch new` is
+ run after the upgrade. The upgrade is not reversible, and the
+ upgraded database will not be readable by older versions of
+ Notmuch. As a safeguard, a database dump will be created in the
+ `.notmuch` directory before upgrading.
+
+Build System
+------------
+
+The ruby bindings are now built as part of the main notmuch build
+process. This can be disabled with the `--without-ruby` option to
+configure.
+
+Building the documentation can be disabled with the `--without-docs`
+option to configure.
+
+Skipped individual tests are no longer considered as failures.
+
+Command Line Interface
+----------------------
+
+Database revision tracking
+
+ Two new options were added to support revision tracking. A global
+ option "--uuid" (`notmuch(1)`) was added for to detect counter
+ rollover and reinitialization, and `notmuch-count(1)` gained a
+ `--lastmod` option to query database revision tracking data.
+
+Emacs Interface
+---------------
+
+`notmuch-emacs-version` is used in `User-Agent` header
+
+ The value of recently introduced variable `notmuch-emacs-version` is
+ now used as a part of `User-Agent` header when sending emails.
+
+Removed `notmuch-version` function by renaming it to `notmuch-cli-version`
+
+ With existing variable `notmuch-emacs-version` the accompanied
+ function which retrieves the version of `notmuch-command` is
+ better named as `notmuch-cli-version`.
+
+Query input now supports completion for "is:<tag>".
+
+New message composition mode: `notmuch-compose-mode`
+
+ This is mainly to fix fcc handling, but may be useful for user
+ customization as well.
+
+Library
+-------
+
+The use of absolute paths is now enforced when calling
+`notmuch_database_{open, create}`.
+
+Database revision tracking
+
+ Revision tracking is supported via a new prefix "lastmod:" in the
+ query parser and the new function
+ `notmuch_database_get_revision`. For the latter, see `notmuch(3)`.
+
+New status code returning API for n_query_count_{messages,threads}.
+
+Deprecated functions
+
+ `notmuch_query_search_threads`, `notmuch_query_search_messages`,
+ `notmuch_query_count_messages`, and `notmuch_query_count_threads`
+ are all deprecated as of this release. Clients are encouraged to
+ transition to the `_st` variants supporting better error reporting.
+
+nmbug-status
+------------
+
+nmbug-status now supports specifying the sort order for each view
+
+Notmuch 0.20.2 (2015-06-27)
+===========================
+
+Emacs Interface
+---------------
+
+Bug fix for marking messages read in `notmuch-tree` mode.
+
+Notmuch 0.20.1 (2015-06-01)
+===========================
+
+Test Suite
+----------
+
+Work around apparent gdb bug on arm64.
+
+Notmuch 0.20 (2015-05-31)
+=========================
+
+Command-Line Interface
+----------------------
+
+There is a new `mimetype:` search prefix
+
+ The new `mimetype:` search prefix allows searching for the
+ content-type of attachments, which is now indexed. See the
+ `notmuch-search-terms` manual page for details.
+
+Path to gpg is now configurable
+
+ On systems with multiple versions of gpg, you can tell
+ notmuch which one to use by setting `crypto.gpg_path`
+
+Emacs
+-----
+
+Avoid rendering large text attachements.
+
+Improved rendering of CID references in HTML.
+
+Vim
+---
+
+Vim client now respects excluded tags.
+
+Notmuch-Mutt
+------------
+
+Support messages without Message-IDs.
+
+Library
+-------
+
+Undeprecate single message mboxes
+
+ It seems more trouble to remove this feature than expected, so
+ `notmuch new` will no longer nag about mboxes with a single message.
+
+New error logging facility
+
+ Clients should call `notmuch_database_status_string` to retrieve
+ output formerly printed to stderr.
+
+Several bug fixes related to stale iterators
+
+New status code returning API for n_query_search_{messages,thread}
+
+Fix for library `install_name` on Mac OS X
+
+Fix for rounding of seconds
+
+Documentation
+-------------
+
+Sphinx is now mandatory to build docs
+
+ Support for using rst2man in place of sphinx to build the
+ docmumentation has been removed.
+
+Improved notmuch-search-terms.7
+
+ The man page `notmuch-search-terms(7)` has been extended, merging
+ some material from the relicensed wiki.
+
+Contrib
+-------
+
+`notmuch-deliver` is removed. As far as we know, all functionality
+previously provided by `notmuch-deliver` should now be provided by
+`notmuch insert`, provided by the main notmuch binary.
+
+nmbug-status
+------------
+
+`nmbug-status` now only matches local branches when reading
+`status-config.json` from the `config` branch of the `NMBGIT`
+repository. To help new users running `nmbug-status`, `nmbug clone`
+now creates a local `config` branch tracking `origin/config`. Folks
+who use `nmbug-status` with an in-Git config (i.e. you don't use the
+`--config` option) who already have `NMBGIT` set up are encouraged to
+run:
+
+ git checkout config origin/config
+
+in their `NMBGIT` repository (usually `~/.nmbug`).
+
+Notmuch 0.19 (2014-11-14)
+=========================
+
+Overview
+--------
+
+This release improves the reliability of `notmuch dump` and the error
+handling for `notmuch insert`. The new `notmuch address` command is
+intended to make searching for email addresses more convenient. At the
+library level the revised handling of missing messages fixes at least
+one bug in threading. The release also includes several interface
+improvements to the emacs interface, most notably the ability to bind
+keyboard shortcuts to saved searches.
+
+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 deliver` is deprecated
+
+ With this release we believe that `notmuch insert` has reached
+ parity with `notmuch deliver`. We recommend that all users of
+ `notmuch deliver` switch to `notmuch insert` as the former is
+ currently unmaintained.
+
+`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.
+
+Added `notmuch address` subcommand
+
+ This new subcommand searches for messages matching the given search
+ terms, and prints the addresses from them. Duplicate addresses are
+ filtered out. The `--output` option controls which of the following
+ information is printed: sender addresses, recipient addresses and
+ count of duplicate addresses.
+
+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.
+
+Improved handling of the unread tag
+
+ Notmuch now marks an open message read (i.e., removes the unread
+ tag) if point enters the message at any time in a show buffer
+ regardless of how point got there (mouse click, cursor command, page
+ up/down, notmuch commands such as n,N etc). This fixes various
+ anomalies or bugs in the previous handling. Additionally it is
+ possible to customize the mark read handling by setting
+ `notmuch-show-mark-read-function` to a custom function.
+
+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.
+
+`notmuch-show-stash-mlarchive-link-alist` now supports functions
+
+ Some list archives may use a more complicated scheme for referring
+ to messages than just concatenated URL and message ID. For example,
+ patchwork requires a query to translate message ID to a patchwork
+ patch ID. `notmuch-show-stash-mlarchive-link-alist` now supports
+ functions to better cover such cases. See the help documentation for
+ the variable for details.
+
+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 now `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.
