+# 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!
