                                   Changelog
 
 
+Daniel (11 December 2004)
+- Made the test suite HTTP server (sws) capable of using IPv6, and then
+  extended the test environment to support that and also added three test
+  cases (240, 241, 242) that run tests using IPv6. One of them uses a URL that
+  didn't work before the 10 dec fix by Kai Sommerfeld.
+
+- Made a failed file:// resume output an error message
+
+- Corrected the CURLE_BAD_DOWNLOAD_RESUME error message in lib/strerror.c
+
+- Dan Fandrich:
+
+  simplified and consolidated the SSL checks in configure and the usage of the
+  defines in lib/setup.h
+
+  provided a first libcurl.pc.in file for pkg-config (but the result is not
+  installed anywhere at this point)
+
+  extended the cross compile section in the docs/INSTALL file
+
 Daniel (10 December 2004)
 - When providing user name in the URL and a IPv6-style IP-address (like in
   "ftp://user@[::1]/tmp"), the URL parser didn't get the host extracted
