	The [[Regex processing\|regular expression engine]] can now produce traces of regular expression processing to ~~hep~~ debug and optimize regular expressions. There are new user parameters [[REGEXTR parameter\|REGEXTR]] and [[MREGEXTR parameter\|MREGEXTR]], as well as a new [[Regex_processing#Common_regex_options\|"t" option]] on regex method and $function invocations to control this tracing.

			<p>
			Prior to V7.9, daemons did not output header lines.
			Starting with V7.9, HDRCTL may be set to 8 to force daemons to output header lines.</p>

			===New MSGCTLU command to allow message changes by non-managers===
			<p>
			Message behavior may now be changed by non-managers effecting the user's thread only.
			For instance, anyone may now produce a snap on a specific message within their thread which does not affect anyone else.
			See [[MSGCTLU_command\|MSGCTLU]] command for more details.</p>

			===Regex Rewrite===
	<p>		<p>
	The [[Regex processing\|regular expression engine]] has been completely rewritten to make it significantly faster. Tests indicate simple regex is at least three times as fast as the earlier regular expression engine, and 10 times or more faster for more complex regular expressions. In addition, constant regular expressions are now compiled when the containing procedure is compiled to eliminate the runtime cost of regular expression compilation and to detect errors in regular expressions at SOUL compile-time lather than evaluation time.
