+148) Add a config directive to change the CGI_SITE_2_HOST
+     (default: config.privoxy.org).
+
+     If Privoxy is used as reverse proxy or intercepting proxy without
+     getting intercepted requests, error pages created from default templates
+     currently can result in client requests to config.privoxy.org on the
+     Internet which may not be desirable.
+
+149) Use poll() for socket selection so the number of sockets Privoxy
+     can deal with isn't limited to FD_SETSIZE anymore.
+
+150) Add blacklistd support.
+
+151) Let the dok-tidy target work cross-platform without introducing
+     a ton of white-space changes that hide the content changes.
+
+152) Fix CSS references in the website documentation.
+     For many pages p_doc.css is specified twice using different paths.
+     Usually at least one works, but not all of them do and the
+     duplicated requests are pointless even if they don't end up with
+     a 404.
+
+153) Catch SIGINT and use it to close the listen socket, serve
+     remaining connections and shut down. This would allow higher
+     uptime and make testing more convenient.
+
+154) Underline links in docs and cgi pages. More precisely,
+     don't mess with the browser defaults for link underlining.
+
+155) The sig_handler() shouldn't call log_error().
+     While it isn't known to cause actual problems in normal operation,
+     it's technically incorrect and causes crashes when running in
+     valgrind.
+
+156) Reject socks requests with an explicit error message similar
+     to the one used for ftp. Motivation:
+     https://lists.privoxy.org/pipermail/privoxy-users/2017-March/000195.html
+
+157) Add a directive to control the currently hardcoded receive-buffer size.
+
+158) Use a single thread to wait for new requests on reused client connections.
+     Currently the thread that handles the first request on a connection
+     stays responsible for the client connect until it gets closed.
+     In case of lots of idle connections lots of waiting threads are used.
+     While it's conceivable that this ineffiency is irrelevant from a
+     performance point of view, using a single thread should reduce Privoxy's
+     memory footprint a bit which may be noticeable in case of multi-user setups
+     with hundreds of idle connections.
