+   - XP-2100 Series
+   - XP-2150 Series
+- `epson2`: Marked XP-452 455 series as supported in documentation.
+- `escl`: Fixed scanning problems on certain scanners due to incorrect URL being used
+  (https://gitlab.com/sane-project/backends/-/issues/479)
+- `escl`: Fixed support for different resolutions when using JPEG format.
+- `escl`: Fixed handling of ipp-usb redirects to localhost which previously caused certain scanners
+   to be always reported as busy.
+- `escl`: Added support for Brother DCP-J772DW and Epson ET-2750 scanners.
+- `escl`: Marked the following scanners as supported in documentation:
+   - Canon PIXMA G4511
+   - Canon PIXMA TR4550 Series
+   - Canon PIXMA TR4551 Series
+   - Epson ET-6100
+- `escl`: Implemented support for disabling PDF output on scanners where it's broken
+  (https://gitlab.com/sane-project/backends/-/issues/510)
+- `escl`: Implemented support for Canon PIXME TR4520 and TR7500 scanners.
+- `genesys`: Improved scan quality on Canon LiDE 35/40/50/60 by using brighter LED illumination.
+- `genesys`: Fixed control of contrast and brigthness on certain scanners
+  (https://gitlab.com/sane-project/backends/-/issues/271).
+- `genesys`: Fixed crashes when handling slightly unexpected conditions
+  (https://gitlab.com/sane-project/backends/-/issues/464).
+- `genesys`: Fixed support for Plustek Opticfilm 7200 v2 scanner.
+- `genesys`: Fixed button support on HP ScanJet G4010.
+- `genesys`: Fixed compilation on gcc-4.8.
+- `genesys`: Fixed incorrect LED exposure calculation leading to wrong color balance on certain
+  resolutions on gl841 scanners
+- `genesys`: Improved gray scan quality on Canon LiDE 110, 120, 210, 220
+  (https://gitlab.com/sane-project/backends/-/issues/106,
+  https://gitlab.com/sane-project/backends/-/issues/52).
+- `genesys`: Fixed issue of motor becoming stuck at certain resolutions on Canon LiDE 50
+  and possibly other gl841 scanners (https://gitlab.com/sane-project/backends/-/issues/357)
+- `genesys`: Fixed periodic black lines in gray scans on Canon LiDE 80.
+- `genesys`: Removed support for broken 75 and 100 dpi hardware resolutions to fix preview
+  scans (https://gitlab.com/sane-project/backends/-/issues/383). These resolutions did
+  not have any benefit compared to next smallest 150 dpi resolution.
+- `genesys`: Add support for running in embedded environments that don't support threads.
+- `genesys`: Fixed gray scans to use white color for illumination instead of red on
+  Canon LiDE 35/40/50/60 and potentially other gl841 scanners. Old behavior can
+  be restored via the color filter setting to select specific color component for
+  the gray scan.
+- `genesys`: The genesys backend is now distributed under GPL v2 or later license.
+  Previously there existed an exception that allowed additional uses of the backend.
+- `gt68xx`: Fixed several memory issues that can potentially lead to crashes or increased memory use.
+- `hp4200`: Fixed crash when using HP ScanJet 4200C
+  (https://gitlab.com/sane-project/backends/-/issues/454).
+- `microtek`: Fixed support for embedded platforms using `uclibc`.
+- `pieusb`: Implemented support for Reflecta RPS 10M scanner.
+- `pieusb`: Fixed support for automatically advancing slides on DigitDia 4000.
+- `pixma`: Fixed compliation with `NDEBUG` macro defined.
+- `pixma`: Marked Canon PIXMA G4511 as supported in documentation
+- `scangearmp2`: Mark GX6000, GX7000, TS5400 and MX455 series as supported.
+- `sm3600-scanutil`: Fixed support for embedded platforms using `uclibc`.
+
+
+### Frontends
+
+- Improved documentation of `scanimage` concerning options provided by backends.
+- `scanimage`: Improved help to specify which options are advanced.
+- `scanimage`: Implemented support for PDF output format.
+
+
+### Miscellaneous
+
+- Added translation to Simplified Chinese.
+
+

+# Creating A New `sane-backends` Release
+
+This file summarizes most points to pay attention to when planning for
+a new `sane-backends` release.  Content has been checked while working
+on `$old_version` and getting ready for `$new_version`, where:
+
+``` sh
+old_version=1.0.31
+new_version=1.0.32
+```
+
+## Timetable
+
+It is easiest to pick a release date well in advance so everyone knows
+what to expect.  Ignoring security bug fix releases, `sane-backends`
+has been released on a roughly half-yearly schedule since `1.0.28`.
+
+Once you pick a date (and time), say `DT`, the planning is simply a
+matter of counting back from there:
+
+ - `$DT -  0 days`: **release** :confetti_ball:
+ - `$DT - 21 days`: **branch off** after which the release branch will not get any new features,
+   only bug fixes and translations.
+ - `$DT - 35 days`: **schedule announcement** including the timetable.
+
+Feel free to adjust the offsets if that works better.  Also, pinging
+on the mailing list well in advance, say two, three months, about a
+suitable date for everyone involved is a good idea.
+
+> If you mention time of day, on the mailing list, in issues or merge
+> requests, use UTC times and mention that, e.g. 09:00 UTC.  People
+> are in time zones all over the place and converting to and from UTC
+> should be relatively easy for everyone.  Converting from other
+> time zones is generally cumbersome, even without things like DST.
+
+## Schedule Announcement
+
+Send an announcement to the `sane-devel` mailing list announcing the schedule.
+
+All notable changes are tracked as separate files in the newsfragments directory which means there's
+no need to track them manually.
+
+## Branch off
+
+A separate branch for the upcoming release is created on the repository. This marks the point when
+the code for the release effectively enters a feature freeze and no new features will land into
+the release branch.
+
+Use branch in the format of `release-1.2.x` so that it's clear that further bugfix releases will
+happen on that branch.
+
+Notify `sane-devel` of the Branch Off and point out that merge requests that have to be included
+in the upcoming release need to be targeted at release branch. Anything else can go to `master` as
+usual.
+
+For backends added since the `$old_version`, make sure that its
+`.desc` file includes a `:new :yes` near the top.  You can find such
+backends from the list of added files with:
+
+``` sh
+git ls-files -- backend | while read f; do
+  git log --follow --diff-filter=A --find-renames=40% \
+          --format="%ai  $f" $old_version..release/$new_version -- "$f"
+done | cat
+```
+
+Feature changes are no longer allowed, bar exceptional circumstances, so now is a good time to
+sync the `po/*.po` files in the repository for translators.
+
+Announce the Branch Off on `sane-devel` and invite translators to contribute their updates.
+Release manager should ensure that whichever branch the translator work on, their work lands on
+both the release branch and the master branch.
+
+Occasionally, you may notice changes that have not been documented,
+either in a `.desc` file or a manual page.  Now is a good time to
+rectify the omission.
+
+The `NEWS` file is updated during the release time, there's no need to do anything with the
+release notes now.
+
+## Release
+
+The release consists of two parts: a release notes MR and the actual release.
+
+The release notes are handled by the towncrier tool. The easiest way to use it is from virtualenv:
+
+``` sh
+virtualenv some/path/to/virtualenv
+source some/path/to/virtualenv
+pip install towncrier
+```
+
+To update the `NEWS `document, run the following:
+
+```
+towncrier --version $new_version --date `date -u  +%F`
+```
+
+After that, create a new MR, merge it and fetch the new release branch.
+
+The actual release is as easy as pushing a tag and clicking a web UI button.  GitLab CI/CD
+takes care of the rest.
+
+``` sh
+git tag -a -s $new_version -m "Release $new_version"
+git push --tags origin release-$new_release
+```
+
+The final job in the release pipeline that is triggered by the above
+is a manual job.  You have to press a button in the web UI.  However,
+before you do so, create a Personal Access Token (with `api` scope) in
+your own GitLab account's `Settings` > [`Access Tokens`][] and use its
+value to set the `PRIVATE_TOKEN` variable for the `upload` job in the
+`Release` stage.  You need to set this on the page that triggers the
+`upload` job.
+
+ [`Access Tokens`]: https://gitlab.com/-/profile/personal_access_tokens
+ [`CI/CD`]: https://gitlab.com/sane-project/backends/-/settings/ci_cd
+
+### Updating The Website
+
+After the release artifacts, i.e. the source tarball, have hit the
+GitLab [Release][] tab, grab the source tarball to create updated
+lists of supported devices and HTML manual pages for the website.
+
+With the `$new_version`'s source tarball:
+
+``` sh
+tar xaf sane-backends-$new_version.tar.gz@
+cd sane-backends-$new_version
+./configure
+make -C lib
+make -C sanei
+make -C doc html-pages
+LANG=C make -C doc html-man
+```
+
+The last command assumes you have `man2html` in your `$PATH`.  There
+are various versions of this command but `make` assumes you are using
+the version from one of:
+
+- https://savannah.nongnu.org/projects/man2html/
+- https://web.archive.org/web/20100611002649/http://hydra.nac.uci.edu/indiv/ehood/tar/man2html3.0.1.tar.gz
+
+Using anything else is asking for trouble.
+
+> See also #261.
+
+With the various HTML pages generated in `sane-backends-$new_version`,
+check out the latest code of the sane-project/website and:
+
+``` sh
+cd website
+rm man/*
+cp .../sane-backends-$new_version/doc/*.[1578].html man/
+git add man/
+git mv sane-backends.html sane-backends-$old_version.html
+cp .../sane-backends-$new_version/doc/sane-{backends,mfgs}.html .
+git add sane-{backends,mfgs}.html
+```
+
+Next, add a hyperlink to the `$old_version`'s file in
+`sane-supported-devices.html` and add an entry for the new release to
+`index.html`.
+
+Finally
+
+``` sh
+git add sane-supported-devices.html index.html
+git commit -m "Update for sane-backends-$new_version release"
+git push
+```
+
+The push will trigger a GitLab CI/CD pipeline that will update the
+website.  Make sure it succeeds (see sane-project/website#33 for one
+reason it might fail).
+
+ [Release]: https://gitlab.com/sane-project/backends/-/releases
+
+### Mailing List Announcement
+
+Once the website has been updated successfully, announce the release
+on the `sane-announce` mailing list (and Cc: `sane-devel`).  You may
+want to ping the `sane-announce` list's moderator (@kitno455) to get
+your post approved sooner rather than later.
+
+## Post-Release
+
+With the release all done, there are still a few finishing touches that need taking care of:
+
+* remove the `:new` tag from all `doc/descriptions*/*.desc` files
+* update this file!
+
+That's All Folks!

-This text summarizes some points to pay attention to when a new release
-of sane-backends is planned.
-
-Timetable (approximate periods):
-
-Day  0: Announcement of upcoming release on sane-devel including timetable
-        and pointer to the GitLab milestone
-Day 14: Feature freeze (only bugfixes + documentation updates)
-Day 28: Code freeze (only fixes for bugs that can destroy hardware, can cause
-        compilation problems or render a backend completely unusable, and
-        documentation updates are allowed)
-Day 35: Release
-
-Before the release:
-
-* set :new :yes on any new backend .desc files, by looking for added files:
-
-  version=1.0.27
-  git ls-files -- backend | while read f; do
-    git log --follow --diff-filter=A --find-renames=40% \
-            --format="%ai  $f" $version..HEAD -- "$f"
-  done | cat
-
-* NEWS: update and enter date of release, etc
-  Get list of heavily change backends via: git diff --stat $version..HEAD
-  Get list of details from: git log $version..HEAD
-* git commit -a
-* git push origin master
-
-Making the release:
-
-* temporarily set a PRIVATE_TOKEN variable in the GitLab CI/CD
-  variables.  You have to create one in your own Settings > Access
-  Tokens.  Set it to expire the next day to avoid abuse.  Better yet,
-  remove it from the CI/CD variables when the job is finished.
-* git tag -a -s 1.0.28 -m Release
-* git push --tags origin master
-* trigger the manual 'release' stage of the build via the web UI when
-  this becomes possible.  This requires a valid PRIVATE_TOKEN.
-
-Updating the website and announcing the release:
-
-* checkout the sane/website.git module and:
-* copy sane-backends.html to sane-backends-"old-version".html
-* update sane-supported-devices.html with link to above "old" file
-* rebuild sane-backends.html and sane-mfgs.html (make -C doc html-pages)
-* [TBD] use man2html from http://hydra.nac.uci.edu/indiv/ehood/man2html.html
-  to rebuild html man pages (make -C doc html-man) (no other version works)
-* update announcement to index.html
-* git commit -a && git push
-* check that website's pipeline succeeded
-* announce release on sane-announce mailing list (and Cc: sane-devel).
-  Ping the sane-announce list's moderator (m. allan noah) to get your
-  post approved ASAP.
-
-After the release:
-
-* remove the ':new' tag from all doc/descriptions*/*.desc files
-* git add new and changed files and commit
-* git push

+This is the directory for release note fragments processed by
+[towncrier](https://github.com/twisted/towncrier).
+
+When making a user-visible change create a file in this directory and it will be automatically be
+included into the release note document when the next release is published.
+
+The file extension specifies the type of a change. The following are currently supported:
+
+ - .backend: a new feature or a bugfix for a backend.
+ - .frontend: a new feature or a bugfix for a backend.
+ - .security: a fix for security issue.
+ - .removal: a deprecation or removal of functionality.
+ - .misc: miscellaneous changes
+
+Please don't add links to the merge requests into the release notes. If it's not clear where
+the feature is coming from by looking into the git history (e.g. if a release note is being
+made after the MR has landed) then add link to the MR to the commit description.
+
+Please add links to fixed issues in Gitlab by using full URLs to them instead of Gitlab
+shorthand syntax.
