15 @section Development phases
17 There are 2.5 states of development for LilyPond.
21 @item @strong{Stable phase}:
22 Starting from the release of a new major version @code{2.x.0}, the
23 following patches @strong{MAY NOT} be merged with master:
26 @item Any change to the input syntax. If a file compiled with a
27 previous @code{2.x} version, then it must compile in the new
30 @item New features with new syntax @emph{may be committed},
31 although once committed that syntax cannot change during the
32 remainder of the stable phase.
34 @item Any change to the build dependencies (including programming
35 libraries, documentation process programs, or python modules used
36 in the buildscripts). If a contributor could compile a previous
37 lilypond @code{2.x}, then he must be able to compile the new
42 @item @strong{Development phase}:
43 Any commits are fine. Readers may be familiar with the term
44 @qq{merge window} from following Linux kernel news.
47 @item @strong{Release prep phase}:
48 TODO: I don't like that name.
50 A new git branch @code{stable/2.x} is created, and a major release
55 @item @code{stable/2.x branch}:
56 Only translation updates and important bugfixes are allows.
59 Normal @qq{stable phase} development occurs.
63 If we discover the need to change the syntax or build system, we
64 will apply it and re-start the release prep phase.
68 This marks a radical change from previous practice in LilyPond.
69 However, this setup is not intended to slow development -- as a
70 rule of thumb, the next development phase will start within a
71 month of somebody wanting to commit something which is not
72 permitted during the stable phase.

226 * write release notes. note: stringent size requirements for
227 various websites, so be brief.
229 * write preface section for manual.
231 * submit pots for translation : send url of tarball to
232 translation@@iro.umontreal.ca, mentioning lilypond-VERSION.pot
236 * Check all 2ly scripts.
238 * Run convert-ly on all files, bump parser minimum version.
240 * update links to distros providing lilypond packages? link in
241 Documentation/web/download.itexi . This has nothing to do with
242 the release, but I'm dumping this here so I'll find it when I
243 reorganize this list later. -gp
245 * Make FTP directories on lilypond.org
248 - Make new table in download.html
250 - add to documentation list
252 - revise examples tour.html/howto.html
254 - add to front-page quick links
256 - change all links to the stable documentation
258 - doc auto redirects to v2.LATEST-STABLE
260 - add these two lines to http://www.lilypond.org/robots.txt:

425 A translator can ask for an official lilypond-xy mailing list once
426 they've finished all @qq{priority 1} translation items.
428 @subsubheading Performing yearly copyright update (@qq{grand-replace})
430 At the start of each year, copyright notices for all source files
431 should be refreshed by running the following command from the top of
438 Internally, this invokes the script @file{scripts/build/grand-replace.py},
439 which performs a regular expression substitution for old-year -> new-year
440 wherever it finds a valid copyright notice.
442 Note that snapshots of third party files such as @file{texinfo.tex} should
443 not be included in the automatic update; @file{grand-replace.py} ignores these
444 files if they are listed in the variable @code{copied_files}.
