Memcached 1.6.19

Many fixes and new features for the Proxy feature. Rest are small fixes or code \ 
cleanups to the cache daemon. If you're trying out the Proxy code, please \ 
upgrade or continue to track the next branch.

If you use the lru_crawler metadump hash command, specifically the hash mode, \ 
there is a fix for potential slowdowns.

-Werror is no longer the default when compiling. Add --enable-werror to restore \ 
the feature.
