CONF_modules_unload() now calls CONF_modules_finish() automatically. Default use of section openssl_conf moved to CONF_modules_load() Load config file in several openssl utilities. Most utilities now load modules from the config file, though in a few (such as version) this isn't done because it couldn't be used for anything. In the case of ca and req the config file used is the same as the utility itself: that is the -config command line option can be used to specify an alternative file.
