Notes about GLib 2.20

friends) now passes a FUSE file:// URI if possible (requires gvfs
with the FUSE daemon to be running and operational). With gvfs 2.26,
FUSE file:// URIs will be mapped back to gio URIs in the GFile

* The recommended way of using GLib has always been to only include the
- toplevel headers glib.h, glib-object.h and gio.h. GLib enforces this by
- generating an error when individual headers are directly included.
- To help with the transition, the enforcement is not turned on by
+ toplevel headers glib.h, glib-object.h and gio.h. GLib enforces this by
+ generating an error when individual headers are directly included.
+ To help with the transition, the enforcement is not turned on by
default for GLib headers (it is turned on for GObject and GIO).
To turn it on, define the preprocessor symbol G_DISABLE_SINGLE_INCLUDES.

Notes about GLib 2.16
=====================
* GLib now includes GIO, which adds optional dependencies against libattr
- and libselinux for extended attribute and SELinux support. Use

--disable-xattr and --disable-selinux to build without these.

* The Unicode support has been updated to Unicode 4.1. This adds several
new members to the GUnicodeBreakType enumeration.

intended to serve as a common implementation of the 'floating reference'
consideration, and use the gstdio wrappers to access files whose
names have been constructed from strings returned from GLib.

* On Windows, GLib no longer opens a console window when printing
stderr if you need to see them.
* The child watch functionality tends to reveal a bug in many

+GLib is part of the GNOME git repository. At the current time, any
+person with write access to the GNOME repository, can make changes to
+GLib. This is a good thing, in that it encourages many people to work
+on GLib, and progress can be made quickly. However, GLib is a fairly
+large and complicated package that many other things depend on, so to
+avoid unnecessary breakage, and to take advantage of the knowledge
+about GLib that has been built up over the years, we'd like to ask
+people committing to GLib to follow a few rules:
+
+0) Ask first. If your changes are major, or could possibly break existing
+ code, you should always ask. If your change is minor and you've
+ been working on GLib for a while it probably isn't necessary
+ to ask. But when in doubt, ask. Even if your change is correct,
+ somebody may know a better way to do things.
+
+ If you are making changes to GLib, you should be subscribed
+ to gtk-devel-list@gnome.org. (Subscription address:
+ gtk-devel-list-request@gnome.org.) This is a good place to ask
+ about intended changes.
+
+ #gtk+ on GIMPNet (irc.gimp.org, irc.us.gimp.org, irc.eu.gimp.org, ...)
+ is also a good place to find GTK+ developers to discuss changes with,
+ however, email to gtk-devel-list is the most certain and preferred
+ method.
+
+1) Ask _first_.
+
+2) With git, we no longer maintain a ChangeLog file, but you are expected
+ to produce a meaningful commit message. Changes without a sufficient
+ commit message will be reverted. See below for the expected format
+ of commit messages.
+
+Notes:
+
+* When developing larger features or complicated bug fixes, it is
+ advisable to work in a branch in your own cloned GLib repository.
+ You may even consider making your repository publically available
+ so that others can easily test and review your changes.
+
+* The expected format for git commit messages is as follows:
+
+=== begin example commit ===
+Short explanation of the commit
+
+Longer explanation explaining exactly what's changed, whether any
+external or private interfaces changed, what bugs were fixed (with bug
+tracker reference if applicable) and so forth. Be concise but not too brief.
+=== end example commit ===
+
+ - Always add a brief description of the commit to the _first_ line of
+ the commit and terminate by two newlines (it will work without the
+ second newline, but that is not nice for the interfaces).
+
+ - First line (the brief description) must only be one sentence and
+ should start with a capital letter unless it starts with a lowercase
+ symbol or identifier. Don't use a trailing period either. Don't exceed
+ 72 characters.
+
+ - The main description (the body) is normal prose and should use normal
+ punctuation and capital letters where appropriate. Normally, for patches
+ sent to a mailing list it's copied from there.
+
+ - When committing code on behalf of others use the --author option, e.g.
+ git commit -a --author "Joe Coder <joe@coder.org>" and --signoff.
