+Daniel (8 February 2005)
+- Gisle fixed problems when libcurl runs out of memory, and worked on making
+  sure the proper error code is returned for those occations.
+
+Daniel (7 February 2005)
+- Maruko pointed out a problem with inflate decompressing exactly 64K
+  contents.
+
+Daniel (5 February 2005)
+- Eric Vergnaud found a use of an uninitialised variable in the ftp when doing
+  PORT on ipv6-enabled hosts.
+
+- David Byron pointed out we could use BUFSIZE to read data (in
+  lib/transfer.c) instead of using BUFSIZE -1.

 changelog of the current development status, as one or more of these problems
 may have been fixed since this was written!
 
+20. valgrind errors occur too often when 'make test' is used. It is because
+  too many third-party libs and tools have problems. When curl is built
+  without --disable-shared, the testing is done with a front-end script which
+  makes the valgrind testing include (ba)sh as well and that often causes
+  valgrind errors. Either we improve the valgrind error scanner a lot to
+  better identify (lib)curl errors only, or we disable valgrind checking by
+  default.
+
 19. FTP 3rd party transfers with the multi interface doesn't work. Test:
   define CURL_MULTIEASY, rebuild curl, run test case 230 - 232.
