What's new in at-spi2-core 1.91.90: * BGO#641164: Fixed several build errors. * Fixed some memory leaks and possible crashes. * Fixed atspi_selection_get_selected_child and atspi_selection_get_n_selected_children. * Fixed wrong introspection information in some places. * BGO#641869: Removed the --enable-relocate option. * Avoid returning uninitialized data on error for some methods. * Use the GSettings rather than GConf key to test that accessibility is enabled. * Change some enums from 16-bit to 32-bit to match spec.
