                        Making a new wxWidgets release
                        ==============================

Before making the release
-------------------------

Update docs/readme.txt. Please review its contents in addition to just
changing the version number.

Put a date on the release line in docs/changes.txt.

Update the date in the manual (docs/doxygen/mainpages/manual.h).

Update the release announcement post in docs/publicity/announce.txt.


Creating release files
----------------------

Currently our release system uses a Python 2.x script to generate releases.
The script requires Unix utilities such as tar, zip and unix2dos and thus must
be run either on Unix or using Cygwin on Windows. To generate a release, simply
run the following command:

build/tools/create-archive.py --compression=all /path/to/output/dir

This will produce zip, gzip and bzip archives of the tree (without
"compression" argument only .gz is made). Note that this commands produces huge
amounts of output so redirecting it to a file is recommended.

To add a prefix to the release, such as RC1, the SVN revision, or a date, just
pass --postfix="postfix" to the script. More info on the options and their
possible values can be found by calling `create-archive.py --help`.

IMPORTANT NOTE: You *must* run this script from a clean source tree, that is,
          with no junk files in it or modifications. This is because the
          release should be a pristine copy of the tree as of the time of
          release. If you have legitimate modifications in the tree that need
          to be in the release, commit them first.

To generate the windows installer (.exe) and the documentation files (chm and htb formats)
run:

build\tools\bld_chm_exe.bat

which depends on the wxwidgets.iss file, and generates output in the %DAILY% directory. It 
assumes a clean copy of the wxWidgets source tree in %INNO%. Temporary files will be generated 
in the tree from which the batch file is run. It depends on doxygen, a number of gnu
win32 tools and Microsofts htmlhelp compiler. The wxwidgets.iss file should not need 
editing, but you will want to check that the bld_chm_exe.bat has the correct version number.



Alternative non official release scripts
----------------------------------------

If you use git-svn, then you can use alternative script that avoids the
problems such as using non-clean tree and also has better handling of the ends
of lines conversions. To use it you need to run

- build/tools/svn-find-native-eols.pl
- build/tools/git-make-release
- build/tools/make-html-docs

(the last one can also be used without git).


Uploading
---------

Upload the files to SourceForge. This can be done via the web interface or just
scp to sfusername,wxwindows@frs.sf.net:/home/frs/project/w/wx/wxwindows/x.y.z
The following files need to be uploaded:

    wxMSW-Setup-2.9.3.exe
    wxWidgets-x.y.z.7z
    wxWidgets-x.y.z.tar.bz2
    wxWidgets-x.y.z.zip
    wxWidgets-x.y.z_Headers.zip
    wxWidgets-docs-chm-x.y.z.zip
    wxWidgets-docs-html-x.y.z.tar.bz2
    wxWidgets-docs-html-x.y.z.zip

You will need to use the web interface to mark the latest uploaded files as
being "default downloads" for the appropriate platforms (.zip or .exe for MSW,
.tar.bz2 for everything else) as otherwise SourceForge would continue to suggest
people to download old files.

Next, update (at least the versions and SHA1 sums, but maybe more) and upload
docs/release_files.mdwn and docs/release_binaries.mdwn files. They need to be
renamed to README.md on SF to be shown when the directory is viewed, i.e. do:

    scp docs/release_files.mdwn \
        sfuser,wxwindows@frs.sf.net:/home/frs/project/w/wx/wxwindows/x.y.z/README.md
    scp docs/release_binaries.mdwn \
        sfuser,wxwindows@frs.sf.net:/home/frs/project/w/wx/wxwindows/x.y.z/binaries/README.md

And upload the change log too:

    scp docs/changes.txt \
        sfuser,wxwindows@frs.sf.net:/home/frs/project/w/wx/wxwindows/x.y.z


Also upload the files to the FTP mirror at ftp.wxwidgets.org (ask Chris for
access if you don't have it).

Create http://docs.wxwidgets.org/x.y.z/ (ask Bryan to do it if not done yet).


Announcement
------------

Post docs/publicity/announce.txt at least to wx-announce@googlegroups.com.

TODO: where else to announce it?

Update www.wxwidgets.org, usually a news item is enough but something more can
be called for for major releases.

Also update downloads/index.html to mention the new latest release.

Post to wxBlog if necessary.


Version updates
---------------

Trac: mark the milestone corresponding to the release as completed and add a
new version for it to allow reporting bugs against it and create the next
milestone (ask Vadim or Robin to do it or to get admin password).

Run misc/scripts/inc_release to increment micro version, i.e. replace x.y.z
with x.y.z+1 (minor or major versions updates require manual intervention).
