 	* edfcat: better handling of overshooting signal portions.
 	* phasic events detection groundwork.

+	* SF: reingeneered Patterns dialog:
+	  o use band-pass for target frequency matching;
+	  o system, user, experiment and subject-wide patterns:
+	  o obtain match index once, for instantaneous finding
+	    against variable criteria;
+	  o mark matches as annotations;
+	* Fix envelope function.
 
 v.0.7.6 (2012-12-20)
 	* Don't forget to save some .expdesign.conf settings.
