+Notmuch 0.34 (2021-10-20)
+=========================
+
+General
+-------
+
+An optional new s-expression based query parser is available if
+notmuch is built with the `sfsexp` library. See
+notmuch-sexp-queries(7) for syntax, and use `notmuch config get
+built_with.sexpr_queries` to check if notmuch is compiled with
+s-expression query support.
+
+CLI
+---
+
+Support multiple `Delivered-To` headers in notmuch-reply(1).
+
+Emacs
+-----
+
+Functions are now allowed in `notmuch-search-result-format`.
+
+Improvements to unthreaded view on large threads.
+
+Tolerate bad/missing working directory for most commands.
+
+Allow customization of tree drawing symbols in notmuch-tree mode.
+
+Notmuch 0.33.2 (2021-09-30)
+===========================
+
+Tests
+-----
+
+Improve reliability of T355-smime by changing gpgsm initialization.
+
+Notmuch 0.33.1 (2021-09-10)
+===========================
+
+General
+-------
+
+Replace the fully-qualified-domain-name of the host with "localhost"
+in the default email address. This should fix two flaky subtests in
+T590-libconfig.
+
+Notmuch 0.33 (2021-09-03)
+=========================
+
+Library
+-------
+
+Correct documentation about transactions.
+
+Add a configurable automatic commit of transactions. See
+`database.autocommit` in notmuch-config(1).
+
+Document the algorithm used to find a database.
+
+CLI
+---
+
+Define format version 5, which supports sorting the output of
+notmuch-show.
+
+Emacs
+-----
+
+`notmuch` no longer sets `mail-user-agent` on load. To restore the
+previous behaviour of using notmuch to send mail by default, customize
+`mail-user-agent` to `notmuch-user-agent`.
+
+`notmuch-company` now works in `org-msg`.
+
+Improve the display of messages from long threads in unthreaded mode.
+
+Prefer email addresses over User ID when showing valid signatures.
+
+Define a new face `notmuch-jump-key`.
+
+New commands in notmuch-tree view: `notmuch-tree-filter` and `notmuch-tree-filter-by-tag`.
+
+Honour `notmuch-show-text/html-blocked-images` when using `w3m` to
+render html.
+
+Support toggling sort order in notmuch-tree mode.
+
+Ruby
+----
+
+Memory management of allocated notmuch objects (database, messages,
+etc...) is now done via the Ruby GC. This removes all constraints on
+the order of object destruction. Database close and destroy are
+split, following an old library API change.
+
+Vim
+---
+
+Respect excluded tags when showing a thread.
+
+Documentation
+-------------
+
+Fix doc build for Sphinx 4.0.
+
+Improve the markup and linking of the documentation.
+
+Notmuch 0.32.3 (2021-08-17)
+===========================
+
+Library
+-------
+
+Restore location of database via `MAILDIR` environment variable, which
+was broken in 0.32.
+
+Bump libnotmuch minor version to match the documentation in
+`notmuch.h`.
+
+Correct documentation for deprecated database opening functions to
+point out that they (still) do not load configuration information.
+
+CLI
+---
+
+Restore "notmuch config get built_with.*", which was broken in 0.32.
+
+Notmuch 0.32.2 (2021-06-27)
+===========================
+
+General
+-------
+
+Fix a bug from 2017 that can add duplicate thread-id terms to message
+documents.
+
+CLI
+---
+
+Fix small memory leak in notmuch new.
+
+Emacs
+-----
+
+Add `(require 'seq)` for `seq-some`.
+
+Documentation
+-------------
+
+Fix man page build for Sphinx 4.x. Fix variable name in emacs docs.
+
+Tests
+-----
+
+Fix backup creation in `perf-test/T00-new`. Check openssl
+prerequisite in `add_gpgsm_home`.
+
+Notmuch 0.32.1 (2021-05-15)
+===========================
+
+General
+-------
+
+Restore handling of relative values for `database.path` that was
+broken by 0.32. Extend this handling to `database.mail_root`,
+`database.backup_dir`, and `database.hook_dir`.
+
+Reload certain metadata from Xapian database in
+notmuch_database_reopen. This fixes a bug when adding messages to the
+database in a pre-new hook.
+
+Fix default of `$HOME/mail` for `database.path`. In release 0.32, this
+default worked only in "notmuch config".
+
+Emacs
+-----
+
+Restore the dynamically bound variables `tag-changes` and `query` in
+in `notmuch-before-tag-hook` and `notmuch-after-tag-hook`.
+
+Add `notmuch-jump-key` face to fontify keys in `notmuch-jump` and
+related functions. To ensure backward compatibility, the new face
+inherits from `minibuffer-prompt`.
+
+Notmuch 0.32 (2021-05-02)
+=========================
+
+General
+-------
+
+This release includes a significant overhaul of the configuration
+management facilities for notmuch. The previous distinction between
+configuration items that can be modified via plain text configuration
+files and those that must be set in the database via the "notmuch
+config" subcommand is gone, and all configuration items can be set in
+both ways. The external configuration file overrides configuration
+items in the database. The location of database, hooks, and
+configuration files is now more flexible, with several new
+configuration variables. In particular XDG locations are now supported
+as fallbacks for database, configuration and hooks. For more
+information see `notmuch-config(1)`.
+
+Library
+-------
+
+To support the new configuration facilities, several functions and
+constants have been added to the notmuch API. Most notably:
+
+- `notmuch_database_create_with_config`
+- `notmuch_database_open_with_config`
+- `notmuch_database_load_config`
+- `notmuch_config_get`
+
+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 formatted documentation in `notmuch(3)`.
+
+CLI
+---
+
+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.
+
+Emacs
+-----
+
+Completion related updates include: de-duplicating tags offered for
+completion, use the actual initial input in address completion, allow
+users to opt out of notmuch address completion, and do not force Ido
+when prompting for senders.
+
+Some keymaps used to contain bindings for unnamed commands. These
+lambda expressions have been replaced by named commands (symbols), to
+ease customization.
+
+Lexical binding is now used in all notmuch-emacs libraries.
+
+Fix bug in calling `notmuch-mua-mail` with a non-nil RETURN-ACTION.
+
+Removed, inlined or renamed functions and variables:
+ `notmuch-address-locate-command`,
+ `notmuch-documentation-first-line`, `notmuch-folder`,
+ `notmuch-hello-trim', `notmuch-hello-versions` => `notmuch-version`,
+ `notmuch-remove-if-not`, `notmuch-search-disjunctive-regexp`,
+ `notmuch-sexp-eof`, `notmuch-split-content-type`, and
+ `notmuch-tree-button-activate`.
+
+Keymaps are no longer fset, which means they need to be referred to in
+define-key directly (without quotes). If your Emacs configuration has a
+keybinding like:
+ (define-key 'notmuch-show-mode-map "7" 'foo)
+you should change it to:
+ (define-key notmuch-show-mode-map "7" 'foo)
+
+Notmuch 0.31.4 (2021-02-18)
+===========================
+
+Library
+-------
+
+Fix include bug triggered by glib 2.67.
+
+Test
+----
+
+Fix race condition in T568-lib-thread.
+
+Notmuch 0.31.3 (2020-12-25)
+===========================
+
+Bindings
+--------
+
+Fix for exclude tags in notmuch2 bindings.
+
+Build
+-----
+
+Portability update for T360-symbol-hiding.
+
+Library
+-------
+
+Fix for memory error in notmuch_database_get_config_list.
+
+Notmuch 0.31.2 (2020-11-08)
+===========================
+
+Build
+-----
+
+Catch one more occurence of "version" in the build system, which
+caused the file to be regenerated in the release tarball.
+
+Notmuch 0.31.1 (2020-11-08)
+===========================
+
+Library
+-------
+
+Fix a memory initialization bug in notmuch_database_get_config_list.
+
+Build
+-----
+
+Rename file 'version' to 'version.txt'. The old file name conflicted
+with a C++ header for some compilers.
+
+Replace use of coreutils `realpath` in configure.
+
+Notmuch 0.31 (2020-09-05)
+=========================
+
+Emacs
+-----
+
+Notmuch now supports Emacs 27.1. You may need to set
+`mml-secure-openpgp-sign-with-sender` and/or
+`mml-secure-smime-sign-with-sender` to continue signing messages.
+
+The minimum supported major version of GNU Emacs is now 25.1.
+
+Add support for moving between threads after notmuch-tree-from-search-thread.
+
+New `notmuch-unthreaded` mode (added in Notmuch 0.30)
+
+ Unthreaded view is a mode where each matching message is shown on a
+ separate line.
+
+ The main key entries to unthreaded view are
+
+ 'u' enter a query to view in unthreaded mode (works in hello,
+ search, show and tree mode)
+
+ 'U' view the current query in unthreaded mode (works from search,
+ show and tree)
+
+ Saved searches can also specify that they should open in unthreaded
+ view.
+
+ Currently it is not possible to specify the sort order: it will
+ always be newest first.
+
+Notmuch-Mutt
+------------
+
+The shell pipeline executed by notmuch-mutt, which symlinked matched
+files to a maildir for mutt to access is replaced with internal perl
+processing. This search operation is now more portable, and somewhat
+faster.
+
+Library
+-------
+
+Improve exception handling in the library. This should
+largely eliminate terminations inside the library due to uncaught
+exceptions or internal errors. No doubt there are a few uncovered
+code paths still; please report them as bugs.
+
+Add `notmuch_message_get_flag_st` and
+`notmuch_message_has_maildir_flag_st`, and deprecate the existing
+non-status providing versions.
+
+Move memory de-allocation from `notmuch_database_close` to
+`notmuch_database_destroy`.
+
+Handle relative filenames in `notmuch_database_index_file`, as
+promised in the documentation.
+
+Python Bindings
+---------------
+
+Documentation for the python bindings is merged into the main
+sphinx-doc documentation tree. The merged documentation can be built
+with e.g. `make sphinx-html`
+
+Dependencies
+------------
+
+We now support building notmuch against Xapian 1.5 (the current
+development version).
+
+Test Suite
+----------
+
+Test suite fixes for compatibility with Emacs 27.1.
+
+Build System
+------------
+
+Man pages are now compressed reproducibly.
+
+Notmuch 0.30 (2020-07-10)
+=========================
+
+S/MIME
+------
+
+Handle S/MIME (PKCS#7) messages -- one-part signed messages, encrypted
+messages, and multilayer messages. Treat them symmetrically to
+OpenPGP messages. This includes handling protected headers
+gracefully.
+
+If you're using Notmuch with S/MIME, you currently need to configure
+gpgsm appropriately.
+
+Mixed-up MIME Repair
+--------------------
+
+Detect and automatically repair a common form of message mangling
+created by Microsoft Exchange (see index.repaired=mixedup in
+notmuch-properties(7)).
+
+Protected Headers
+-----------------
+
+Avoid indexing the legacy-display part of an encrypted message that
+has protected headers (see
+index.repaired=skip-protected-headers-legacy-display in
+notmuch-properties(7)).
+
+Python
+------
+
+Drop support for python2, focus on python3.
+
+Introduce new CFFI-based python bindings in the python module named
+"notmuch2". Officially deprecate (but still support) the older
+"notmuch" module.
+
+Dependencies
+------------
+
+Support for Xapian 1.2 is removed. The minimum supported version of
+Xapian is now 1.4.0.
+
+Notmuch 0.29.3 (2019-11-27)
+===========================
+
+General
+-------
+
+Fix for use-after-free in notmuch_config_list_{key,val}.
+
+Fix for double close of file in notmuch-dump.
+
+Debian
+------
+
+Drop python2 support from shipped debian packaging.
+
+Notmuch 0.29.2 (2019-10-19)
+===========================
+
+General
+-------
+
+Fix for file descriptor leak when opening gzipped mail files. Thanks
+to James Troup for the bug report and the fix.
+
+Notmuch 0.29.1 (2019-06-11)
+===========================
+
+Build
+-----
+
+Fix for installation failure with `configure --without-emacs`.
+
+Notmuch 0.29 (2019-06-07)
