2002-11-26 Sebastian Wilhelmi <wilhelmi@ira.uka.de> * glib/grand.c, gthread/gthread-impl.c, tests/rand-test.c: Improved the seeding algorithm. Old behaviour can be achived by setting envvar G_RANDOM_VERSION to "2.0". (#99262) * docs/reference/glib/glib-docs.sgml, docs/reference/glib/Makefile.am: Renamed docs/reference/glib/changes-2.0.sgml to docs/reference/glib/changes.sgml and added section for changes from 2.0 to 2.2 (Also corrected 1.0 to 1.2). * README.in, docs/reference/glib/running.sgml, docs/reference/glib/tmpl/random_numbers.sgml, docs/reference/glib/changes.sgml: Added notes about the new seeding algorithm.
