+DONE:
+  * rename L4 acls as L6 ACLs when some content is involved
+
+  * add new L4 ACL checks immediately after accept, before even allocating the
+    buffers ("connection {accept|reject|delay|freeze} {if|unless}").
+
+  * make new patterns available based on stickiness matching :
+      * number of entries in table for the matched pattern
+      * same after having increased the match counter
+
+  * add support for concurrency match in tables
+      * just like stickiness, but counted per session (or request), increased
         on first match and decreased at end of request or connection. This
         requires that the session has a list of matched terms that must be
         released at the end.
 
+  * http_req_first ACL
+
+  * expirable cookies + "preserve"
+
+  * ECV, LDAPv3 & MySQL checks
+
+  * configurable check buffer size
+
+  * stats + ON/OFF
+
+  * halog: sort by URL
+
+  * "PROXY" protocol

 1.6 (will probably change anyway) :
   - wait on resource (mem, socket, server's conn, server's rate, ...)
