Installation
============

See the file 'INSTALL'


How to report bugs
==================

Bugs should be reported to the GNOME bug tracking system.
(http://bugzilla.gnome.org, product glib.) You will need
to create an account for yourself.

In the bug report please include:

* Information about your system. For instance:

   - What operating system and version
   - For Linux, what version of the C library

  And anything else you think is relevant.

* How to reproduce the bug.

  If you can reproduce it with one of the test programs that are built
  in the tests/ subdirectory, that will be most convenient.  Otherwise,
  please include a short test program that exhibits the behavior.
  As a last resort, you can also provide a pointer to a larger piece
  of software that can be downloaded.

* If the bug was a crash, the exact text that was printed out
  when the crash occured.

* Further information such as stack traces may be useful, but
  is not necessary.


Patches
=======

Patches should also be submitted to bugzilla.gnome.org. If the
patch fixes an existing bug, add the patch as an attachment
to that bug report.

Otherwise, enter a new bug report that describes the patch,
and attach the patch to that bug report.

Patches should be in unified diff form. (The -up option to GNU diff.)


Release notes for 3.4
=====================

* Scroll events have been separated from button events, and smooth
  scrolling has been added with a separate event mask. Widgets now
  need to have either GDK_SCROLL_MASK or GDK_SMOOTH_SCROLL_MASK in
  their event mask to receive scroll events.

* The -uninstalled variants of the pkg-config files have been dropped.

Release notes for 3.2
=====================

* The accessible implementations for GTK+ widgets have been integrated
  into libgtk itself, and the gail module does not exist anymore. This
  change should not affect applications very much.

Release notes for 3.0
=====================

* GTK+ 3 is a major new version of GTK+, which is parallel installable
  with GTK+ 2.x. For information about porting applications from GTK+ 2.x
  to GTK+ 3, see the file:

  docs/reference/gtk/html/migrating.html

  Or online at:

  http://library.gnome.org/devel/gtk/3.0/migrating.html

* Note that the library sonames in this release have been changed from
  libgtk-3.0 and libgdk-3.0 to libgtk-3 and libgdk-3, to prevent the
  library versions from going backwards, compared to the 2.90/91/99
  releases. Applications will have to be recompiled.
