+Notes about GLib-2.2.0
======================
-* On systems without the libintl from GNU gettext() or a recent version
- of the GNU C library, the encoding of translated error messages will be
- incorrect (they should be in UTF-8). A workaround for this is to install
- GNU gettext and use that libintl. This is expected to be fixed in GLib-2.0.1.
- Application programmers should not call g_locale_to_utf8() on these
- strings.
+* GLib changed the seeding algorithm for the pseudo-random number
+ generator Mersenne Twister, as used by GRand and GRandom. This was
+ necessary, because some seeds would yield very bad pseudo-random
+ streams. Further information can be found at:
-* The results of g_strerror() are currently in the encoding of the locale
- rather than in UTF-8. Again, this is a bug, and not behavior that
- should be relied upon.
+ http://www.math.keio.ac.jp/~matumoto/emt.html
-* Similarly, the GLib error logging functions such as g_print(), g_warning(),
- g_error(), currently do not convert the strings they are passed from
- UTF-8 to the encoding of the locale, or check that the strings they
- are passed are valid UTF-8. They should, despite this, be assumed to take
- UTF-8 arguments.
+ Also the pseudo-random integers generated by g_rand_int_range and
+ g_random_int_range will have a slightly better equal distribution
+ with the new version of GLib.
+
+ The original algorithms, as found in GLib-2.0.x, can be used instead
+ of the new ones by setting the environment variable G_RANDOM_VERSION
+ to the value of "2.0".
+ Use the GLib-2.0 algorithms only if you have sequences of numbers
+ generated with Glib-2.0 that you need to reproduce exactly.
