    1.50
	 * New set of process spawn functions.  [T6249]
	 * Fixed return type for gpgrt_b64dec_proc and gpgrt_b64dec_finish to
	   gpg_err_code_t.  This enum return type is in almost all cases
	   compatible to the formerly used gpg_error_t (i.e. unsigned int).
	 * Interface changes relative to the 1.49 release:
		 gpgrt_process_t                     CHANGED (never used).
		 gpgrt_spawn_actions_t               NEW type.

    1.49
	 * Two new functions to improve the logging interface.  The
	   gpgrt_logv_domain is currently the same as gpgrt_logv_prefix but
	   allows to pass a domain string so that in future we will be able to
	   select log output by domain.  It also provide a non yet functional
	   feature to include a hex dump.
	 * Add a "trunc" keyword to gpgrt_log_printhex.  [rE0a39fbefcb]
	 * Avoid an endless loop in the argparser due to a conf file read
	   error.  [rE2dc93cfecc]
	 * Interface changes relative to the 1.48 release:
		 gpgrt_add_post_log_func        NEW.
		 gpgrt_logv_domain              NEW.
