+Version 3.49
+
+  [BUG FIXES]
+  1. Fix a regression since 3.44 involving a case when the header includes "Content-Length: 0". 
+     Thanks to Alex Vandiver (RT#51109)
+  2. Suppress uninitialized warnings under -w. Thanks to burak.  (RT#50301)
+  3. url() now uses virtual_port() instead of server_port(). Thanks to MKANAT and Yanick Champoux. (RT#51562)
+
+  [SECURITY]
+  1. embedded newlines are now filtered out of header values in header(). 
+     Thanks to Mark Stosberg and Yanick Champoux.
+
+  [DOCUMENTATION]
+  1. README was updated to reflect that CGI.pm was moved under ./lib. 
+     Thanks to Alex Vandiver.
+
+  [INTERNALS]
+  1. More tests were added for autoescape, thanks to Bob Kuo. (RT#25485)
+  2. Attempt to avoid test failures with t/fast, thanks to Steve Hay. (RT#49599)
