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 occurred.
* Further information such as stack traces may be useful, but
is not necessary.
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)
Even better are git-formatted patches. (Use git format-patch)
Release notes for releases of GTK+ 3.x are part of the migration
guide in the GTK+ documentation. See
