The release notes
=================

The release notes should contain the following sections:

- about Sofia-SIP
    - copied verbatim from sofia-sip/README
- list of changes since last release
    - maintained in sofia-sip/RELEASE
    - see diff between cvs/darcs between previous and
      this version
    - written in freshmeat.net "Changes:" style 
- notes on API/ABI interface changes 
    - maintained in sofia-sip/RELEASE
    - all changes in public interfaces, plus other
      notes that developers should be aware of
- contributors to this release
    - maintained in sofia-sip/RELEASE
    - also sofia-sip/AUTHORS should be updated (file
      should list all persons/companies who have code/scripts/etc
      copyrighted to them in the sofia-sip tree)

See the RELEASE.template file for a full list of release note
sections.

Making the release tarball 
==========================

- basics: check system clock of the build host ;)
- update the version number in sofia-sip/configure.ac
- make sure the library versions are correct, and you've
  frozen all library interfaces (with correct entries in
  ChangeLog files), see README.developers for more information
  on library versioning in general
- make sure everything that is supposed to be in the
  release is in the master darcs tree
- run 'make distcheck' to verify everything is ready for
  release (requires automake-1.7 or newer)
- tag repos (darcs and any slave trees) with release tag
  'rel-sofia-sip-x_y_z', where x_y_z is the version number (see
  README.developers):
    sh> darcs tag -m"rel-sofia-sip-x_y_z"
    sh> cvs tag rel-sofia-sip-x_y_z
- take a fresh checkout of the release using the release tag
    sh> darcs get http://sofia-sip.org/repos/sofia-sip --tag=rel-sofia-sip-1_yy_z
- create the release tarball with "make distcheck"
- calculate md5 and sha1 hashes using md5sum and sha1sum utilities,
  and copy the values to the release-notes (see below)

Creating the release notes and updating the website
===================================================

- combine the sofia-sip/RELEASE contents with
  the template found from sfnet_www/templates/relnotes.txt
- store the resulting release notes to 
  sfnet_www/relnotes/relnotes-sofia-sip-x.y.z.txt
- add explicit link to the release notes to 
  sfnet_www/download.html (three most recent releases,
  see guidelines in the html comments)
- update sfnet_www/index.html to mention the latest
  release
- commit the change to sf.net website CVS, and run the 
  sfnet_www/put_online.sh script at the sourceforge.net
  shell server

Uploading the release to sourceforge.net
========================================

- use the the 'Admin' -> 'File releases' tool for
  creating a new release
- to upload the file, you can use for example ncftpput:
  ncftpput -u anonymous -p USER@users.sourceforge.net upload.sourceforge.net /incoming/ sofia-sip-x.y.z.tar.gz
- attach the release notes (relnotes-sofia-sip-x.y.z.txt)
  to the file release

Announcing releases
===================

- send an announcement mail, containing the
  release notes, to sofia-sip-devel@lists.sourceforge.net
- post a news item to freshmeat.net 'sofia-sip'
  project (current project owner: Kai Vehmanen)

After release
=============

- replace the RELEASE file with RELEASE.template, and
  commit it to master source repository (see sofia-sip/README.developers)
- change version in configure.ac from "X.Y.Z" to 
  "X.Y.Zwork" (as it is in many cases unknown what the 
  next version will be)
- make a "tree open for development" commit

Syncing CVS and darcs (or some other VCS)
=========================================

Some tips for synchronizing from/to different version controlled
tree.

- As CVS cannot trace file addition/move/removals, you need
  to be extra careful with these. With darcs, you can use the
  'darcs changes -v' command to track down all fileops since
  last synchronization.

- Always tag the src-tree with "syncuser-fromvcs-to-tovcs-yearmmdd".

- Add a top-level ChangeLog entry that documents all the 
  changes made outside the target tree (what, who and when -
  for example produced with the "darcs changes --summary" 
  command).

Checking API/ABI compatibility
==============================

- Use a unit test binary built against an old library, 
  to verify a new library version (forwards-compatibility).
- Use the 'icheck' tool (in Debian) to make comparison
  between two released versions.
