+Changes to Squid-2.3.DEVEL1 ():
+
+       - Added WCCP support.  This adds the 'wccp_router' squid.conf
+         option.
+       - Added internal DNS queries; Most installations can run
+         without the external dnsserver processes.
+       - Rewrote much of the code that stores cache objects on
+         disk.  Developed a programming interface that should
+         allow new storage systems to be added easily.  This still
+         is pretty ugly and needs a lot of work, however.
+       - Replaced async_io.c "tags" with callback data locks.
+         This probably breaks async IO in a bad way.
+       - Tried to write an Async IO disk storage module.
+       - Added code to replace the StoreEntry linked list with a
+         heap structure.  This allows for different replacement
+         algorithms, instead of being stuck with LRU.  This adds
+         the 'replacement_policy' squid.conf option. (John Dilley
+         et al).
+       - Fixed HTCP queries by actually checking for freshness
+         based on the HTCP header fields.
+       - Fixed passing of redirector command line arguments.
+       - Added 'request_header_max_size' squid.conf option.
+       - Added 'request_body_max_size' squid.conf option.
+       - Added 'reply_body_max_size' squid.conf option.
+       - Added 'peer_connect_timeout' squid.conf option.
+       - Added 'redirector_bypass' squid.conf option.
+       - Added RFC 2518 (WEBDAV) request methods.
+

 Changes to Squid-2.2 (April 19, 1999):
