This was - necessary, because some seeds would yield very bad pseudo-random - streams. Further information can be found at: - - http://www.math.keio.ac.jp/~matumoto/emt.html - - 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. +* GObject now enforces CONSTRUCT_ONLY properties; due to an oversight + in previous versions, it was possible to set CONSTRUCT_ONLY properties + after construct time. + +* The child watch functionality tends to reveal a bug in many + thread implementations (in particular the older LinuxThreads implementation + on Linux) where it's not possible to call waitpid() for a child + created in a different thread. For this reason, for maximum portability, + you should structure your code to fork all child processes that you want + to wait for from the main thread. + +* A problem was recently discovered with g_signal_connect_object(); + it doesn't actually disconnect the signal handler once the object being + connected to dies, just disables it. See the API docs for the function + for further details and the correct workaround that will continue to + work with future versions of GLib. How to report bugs ================== |
