+Here are the steps to follow to create a new cairo release:
+
+0) Decide type of release and checkout the appropriate branch.
+
+ The Cairo project makes three types of releases: Development
+ snapshot releases, stable minor releases, and stable micro (aka
+ "point") releases. Micro releases should be only bugfixes and
+ no API additions. If there are API additions consider making a
+ Minor release. Snapshot releases can be done of the current
+ development tree between Minor releases, as desired.
+
+ For stable releases (both minor and micro), the work should be
+ done on the given release branch. E.g. for 1.14.12, check out
+ the 1.14 branch via "git checkout origin/1.14 -b 1.14".
+
+1) Ensure that there are no local, uncommitted/unpushed mods.
+
+ You're probably in a good state if both "git diff
+ HEAD" and "git log master..origin/master" give no output. Also make
+ sure you have libglib2.0-doc installed (else you'll get
+ excessive gtk-doc cross reference warnings in the next step).
+
+2) Verify that the code passes "make distcheck"
+
+ First, make sure you have 'nm' and 'readelf' commands in PATH.
+ this should be OK with any Linux distro.
+
+ Running "make distcheck" should result in no warnings or
+ errors and end with a message of the form:
+
+ =============================================
+ cairo-X.Y.Z archives ready for distribution:
+ cairo-X.Y.Z.tar.gz
+ =============================================
+
+ (But the tar file isn't actually ready yet, as we still have
+ some more steps to follow).
+
+ Note that it's allowed (and perhaps recommended) to run the
+ "make distcheck" step against an all-software X server such as
+ Xvfb to avoid getting tripped up by any X-server-driver-specific
+ bugs. See test/README for details
+
+ If you get errors about local PLT entries, you get the list of
+ cairo entries with the error. For each of these, a call to
+ slim_hidden_def and slim_hidden_proto is needed in the cairo
+ implementation in the style of other similar calls.
+
+ In the unfortunate case that you have to push a snapshot out
+ (note, I said snapshot, not release) without the entire test
+ suite passing, here's the magic env vars to set when doing
+ 'make distcheck' and 'make release-publish' that will let you
+ get away with it. At any cost, never ever release without
+ (implied) distchecking. Every time we got around it, it turned
+ out to be a disaster. Anyway, here's the pass code:
+
+ DISPLAY= CAIRO_TEST_TARGET=" "
+
+3) Decide what the new version number for the release will be.
+
+ Cairo uses even numbers for official releases, and odd numbers
+ for development snapshots. Thus, for a Minor release it would
+ be:
+
+ LAST_RELEASE="X.Y.Z" # e.g. 1.12.0
+ THIS_RELEASE="X.Y+2.0" # e.g. 1.14.0
+
+ While for a Micro release the version numbers should be:
+
+ LAST_RELEASE="X.Y.Z" # e.g. 1.14.0
+ THIS_RELEASE="X.Y.Z+2" # e.g. 1.14.2
+
+ Snapshots are similar but have odd minor versions. Also, the
+ first snapshot release in a new series will be .2 rather than
+ .0, e.g.:
+
+ LAST_RELEASE="X.Y.Z" # e.g. 1.14.0
+ THIS_RELEASE="X.Y+1.0" # e.g. 1.15.2
+
+ and subsequent snapshots in that series are just normal micro
+ releases:
+
+ LAST_RELEASE="X.Y.Z" # e.g. 1.15.2
+ THIS_RELEASE="X.Y.Z+2" # e.g. 1.15.4
+
+4) Fill out an entry in the NEWS file
+
+ Sift through the logs since the last release. This is most
+ easily done with a command such as:
+
+ git log --stat ${LAST_RELEASE}..
+
+ Summarize major changes briefly in a style similar to other
+ entries in NEWS. Take special care to note any additions in
+ the API. These should be easy to find by noting modifications
+ to .h files in the log command above. And more specifically,
+ the following command will show each patch that has changed a
+ public header file since the given version:
+
+ find src/ -name '*.h' ! -name '*-private.h' \
+ ! -name 'cairoint.h' ! -name 'cairo-*features*.h' | \
+ xargs git diff ${LAST_RELEASE}.. --
+
+ Include a link to the incremental ChangeLog for this release,
+ which we'll be uploading in a later step:
+
+ https://cairographics.org/releases/ChangeLog.cairo-${THIS_RELEASE}
+
+4) Increment cairo_version_{minor|micro} in cairo-version.h:
+
+ If there are backward-incompatible changes in the API, stop
+ now and don't release. Go back and fix the API instead. Cairo
+ is intended to remain backwards-compatible as far as API.
+
+ So cairo_version_major will not be incremented unless we come
+ up with a new versioning scheme to take advantage of it.
+
+ If there are API additions, then increment cairo_version_minor
+ and reset cairo_version_micro to 0. NOTE: The minor version is
+ only incremented for releases, not for snapshots.
+
+ Otherwise, (i.e. there are only bug fixes), increment
+ cairo_version_micro to the next larger (even) number.
+
+5) For Minor releases, add an index entry to doc/public/cairo-docs.xml
+
+ Towards the end of the file, add a new section for the stable
+ release. It'll look something like:
+
+ <index id="index-X.Y" role="X.Y">
+ <title>Index of new symbols in X.Y</title>
+ </index>
+
+6) Commit the changes to NEWS and cairo-version.h
+
+ It's especially important to mention the new version number in your
+ commit log.
+
+7) Run "make release-publish" which will perform the following steps
+ for you:
+
+ * Generate ChangeLog files out of git repository
+ * Check that ChangeLog files were generated properly
+ * Check that the version number ends with an even micro component
+ * Check that no release exists with the current version
+ * Verify that make distcheck completes successfully
+ * Generate the final tar file
+ * Generate an sha1sum file
+ * Sign the sha1sum using your GPG setup (asks for your GPG password)
+ * scp the three files to appear on https://cairographics.org/releases
+ * Generate a versioned manual and upload it to appear as both:
+ https://cairographics.org/manual-${THIS_RELEASE}
+ https://cairographics.org/manual
+ * Place local copies of the three files in the releases directory
+ * Create a LATEST-package-version file (after deleting any old one)
+ * Tag the entire source tree with a ${THIS_RELEASE} tag, and sign
+ the tag with your GPG key (asks for your GPG password, and you
+ may need to set GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL to match
+ your public-key's setting or this fails.)
+ * Provide some text for the release announcement (see below).
+ If for some reason you lost this message, "make release-publish-message"
+ prints it for you.
+
+ Upload the incremental ChangeLog generated by the above:
+
+ scp ChangeLog.cache-${LAST_RELEASE}.. \
+ cairographics.org:/srv/cairo.freedesktop.org/www/releases/ChangeLog.cairo-${THIS_RELEASE}
+
+ To undo a release-publish, before you've sent any emails or
+ pushed changes to master, delete the locally created tag (git
+ tag -d ${THIS_RELEASE}); then log into the webserver, repoint
+ the manual and LATEST-cairo-${THIS_RELEASE} symlinks to the
+ previous versions, remove manual-${THIS_RELEASE} and
+ release/cairo-${THIS_RELEASE}.
+
+8) Push the new tag out to the central tree with a command like:
+
+ git push origin master ${THIS_RELEASE}
+
+9) Update master (or the stable branch) version number.
+
+ For Micro releases (X.Y.Z+2), increment cairo_version_micro to
+ the next larger (odd) number in cairo-version.h, commit, and
+ push.
+
+ DEVEL_VERSION="X.Y.Z+1" # e.g. 1.15.10 -> 1.15.11
+
+ For Minor releases (X.Y.0), increment cairo_version_minor to the
+ next larger (odd) number, and set cairo_version_micro to 1. Then
+ commit and push.
+
+ DEVEL_VERSION="X.Y.Z+1" # e.g. 1.16.0 -> 1.17.1
+
+ git commit cairo-version.h -m "Bump version for ${DEVEL_VERSION}"
+
+10) Edit the cairo bugzilla product and add the new version numbers.
+
+ Note that you need to add two versions. One for the
+ release/snapshot (with an even micro version), another with the
+ post-release version (with an odd micro version).
+
+11) Send out an announcement message.
+
+ Send a message to cairo-announce@cairographics.org and CC
+ cairo@cairographics.org, gnome-announce-list@gnome.org and
+ ftp-release@lists.freedesktop.org (pr@lwn.net as well for major
+ releases) to announce the new release using the text provided from
+ "make release-publish", adding the excerpt from NEWS and
+ the shortlog of all changes since last release, generated by:
+
+ git shortlog ${LAST_RELEASE}...
+
+12) Add the announcement to the website as a new entry in the news/
+ dir. It will automatically get indexed onto the homepage when the
+ site refreshes.
