Changelog for the c-ares project
+* May 26 2009 (Yang Tse)
+- Added --enable-curldebug configure option to enable and disable building
+ with the low-level curl debug memory tracking 'feature' to allow decoupled
+ setting from --enable-debug, allowing again to build c-ares independently
+ out of the CVS tree.
+
* May 19 2009 (Yang Tse)
- Introduced ares_library_init() and ares_library_cleanup() functions.
