 Revision history for Perl extension Digest::SHA.
 
+5.43  Sat Aug  5 02:36:18 MST 2006
+	- undid Perl Best Practice of favoring 3-argument "open"
+		-- 3-arg version uses different semantics for "-"
+			causing bugs in addfile and shasum
+	- modified underlying C functions to use ANSI prototypes
+		-- requested by Steve Hay (ref. Smoke [5.9.4] 28630)
+		-- K&R style was causing numerous warnings from
+			Borland compiler
+
 5.42  Mon Jul 24 04:04:40 MST 2006
 	- minor code changes suggested by Perl::Critic
 		-- e.g. no bareword filehandles, no 2-argument open's
