@section Development phases
-There are 2.5 states of development for LilyPond.
+There are 2 states of development on @code{master}:
-@itemize
+@enumerate
+
+@item @strong{Normal development}:
+Any commits are fine.
+
+@item @strong{Build-frozen}:
+Do not require any additional or updated libraries or make
+non-trivial changes to the build process. Any such patch (or
+branch) may not be merged with master during this period.
+
+This should occur approximately 1 month before any alpha version
+of the next stable release, and ends when the next unstable branch
+begins.
+
+@end enumerate
-@item @strong{Stable phase}:
-Starting from the release of a new major version @code{2.x.0}, the
-following patches @strong{MAY NOT} be merged with master:
+
+After announcing a beta release, branch @code{stable/2.x}. There
+are 2 states of development for this branch:
+
+@enumerate
+@item @strong{Normal maintenance}:
+The following patches @strong{MAY NOT} be merged with this branch:
@itemize
@item Any change to the input syntax. If a file compiled with a
-previous @code{2.x} version, then it must compile in the new
-version.
+previous @code{2.x} (beta) version, then it must compile in the
+new version.
+
+Exception: any bugfix to a Critical issue.
@item New features with new syntax @emph{may be committed},
although once committed that syntax cannot change during the
@end itemize
-@item @strong{Development phase}:
-Any commits are fine. Readers may be familiar with the term
-@qq{merge window} from following Linux kernel news.
-
-
-@item @strong{Release prep phase}:
-TODO: I don't like that name.
-
-A new git branch @code{stable/2.x} is created, and a major release
-is made in two weeks.
-
-@itemize
-
-@item @code{stable/2.x branch}:
-Only translation updates and important bugfixes are allows.
-
-@item @code{master}:
-Normal @qq{stable phase} development occurs.
-
-@end itemize
-
-If we discover the need to change the syntax or build system, we
-will apply it and re-start the release prep phase.
-
-@end itemize
-
-This marks a radical change from previous practice in LilyPond.
-However, this setup is not intended to slow development -- as a
-rule of thumb, the next development phase will start within a
-month of somebody wanting to commit something which is not
-permitted during the stable phase.

+Only translation updates and important bugfixes are allowed.

Switch to the release branch, get changes, prep release

+announcement. This requires a clean index and work tree. If the
+checkout displays modified files, you might want to run @code{git reset
+--hard} before continuing.
@example
-git checkout release/unstable

git merge origin

If you do not have the previous release test-output tarball, download
it and put it in @code{regtests/}

+# HOME, HTTP_PROXY, TERM
+env -i \
+ HOME=$HOME \
+ HTTP_PROXY=$HTTP_PROXY \
+ bash --rcfile my-bashrc

+@example
+### my-bashrc
+export PS1="\[\e[1;33mGUB-ENV \w\]$ \[\e[0m\]"
+export PATH=$PATH
+export TERM=xterm

+@ref{Precompiled regression tests}.
@item If any work was done on GUB since the last release, upload
binaries to a temporary location, ask for feedback, and wait a day
-or two in case there's any major problems. Or live dangerously
-and just add a sentence to the release notes. Or live even more
-dangerously, and don't tell anybody anything.

+This is the current official guidelines.
+
+@itemize
+@item
+0 Critical issues for two weeks (14 days) after the latest release
+candidate.
+
+@end itemize
-Before release:
-* write release notes. note: stringent size requirements for
- various websites, so be brief.
+@subheading Potential requirements
-* write preface section for manual.
+These might become official guidelines in the future.
+
+@itemize
+@item
+Check reg test
-* submit pots for translation : send url of tarball to
-translation@@iro.umontreal.ca, mentioning lilypond-VERSION.pot
+@item
+Check all 2ly scripts
+
+@item
+Check for emergencies the docs:
+
+@example
+grep FIXME --exclude "misc/*" --exclude "*GNUmakefile" \
+ --exclude "snippets/*" ????*/*
+@end example
-* Check reg test
+@item
+Check for altered regtests, and document as necessary. (update
+numbers in the following command as appropriate)
-* Check all 2ly scripts.
+@example
+git diff -u -r release/2.12.0-1 -r release/2.13.13-1 input/regression/

-* Run convert-ly on all files, bump parser minimum version.
+@end itemize
-* update links to distros providing lilypond packages? link in
-Documentation/web/download.itexi . This has nothing to do with
-the release, but I'm dumping this here so I'll find it when I
-reorganize this list later. -gp
-* Make FTP directories on lilypond.org
+@subheading Housekeeping requirements
-* website:
- - Make new table in download.html
+Before the release:
- - add to documentation list
+@itemize
+@item
+write release notes. note: stringent size requirements for
+various websites, so be brief.
- - revise examples tour.html/howto.html
+@item
+Run convert-ly on all files, bump parser minimum version.
- - add to front-page quick links
+@item
+Update lilypond.pot:
- - change all links to the stable documentation
+@example
+make po-replace
+@end example
- - make a link from the old unstable to the next stable in
- lilypond.org's /doc/ dir. Keep all previous unstable->stable
- doc symlinks.
+@item
+Make directories on lilypond.org:
- - doc auto redirects to v2.LATEST-STABLE
+@example
+~/web/download/sources/v2.14
+~/web/download/sources/v2.15
+@end example
- - add these two lines to http://www.lilypond.org/robots.txt:
+@item
+Shortly after the release, move all current contributors to
+previous contributors in:
@example
-Disallow: /doc/v2.PREVIOUS-STABLE/
-Disallow: /doc/v2.CURRENT-DEVELOPMENT/
+Documentation/included/authors.itexi
@end example
-- check for emergencies the docs:
+Also, delete old material in:
@example
-grep FIXME --exclude "misc/*" --exclude "*GNUmakefile" \
- --exclude "snippets/*" ????*/*
+Documentation/changes.tely
@end example
-- check for altered regtests, and document as necessary. (update
- tags as appropriate)
+but don't forget to check it still compiles! also update the
+version numbers.

+@item
+Website:
+
+@itemize
+@item
+make a link from the old unstable to the next stable in
+lilypond.org's /doc/ dir. Keep all previous unstable->stable doc
+symlinks.
+
+Also, make the old docs self-contained -- if there's a redirect in
+/doc/v2.12/Documentation/index.html , replace it with the
+index.html.old-2.12 files.
+
+The post-2.13 docs will need another way of handling the
+self-containment. It won't be hard to whip up a python script
+that changes the link to ../../../../manuals.html to
+../website/manuals.html , but it's still a 30-minute task that
+needs to be done before 2.16.
+
+@item
+doc auto redirects to v2.LATEST-STABLE
+
+@item
+add these two lines to http://www.lilypond.org/robots.txt:
@example
-git diff -u -r release/2.12.0-1 -r release/2.13.13-1 input/regression/
+Disallow: /doc/v2.PREVIOUS-STABLE/

+coordinator@@translationproject.org, mentioning lilypond-VERSION.pot
+
+@item
+update links to distros providing lilypond packages? link in:
+@file{Documentation/web/download.itexi}
+
+This has nothing to do with the release, but it's a "periodic
+maintenance" task that might make sense to include with releases.
