error pages. Please read the page at http://squid.nlanr.net/Squid/v2/2.2/
before installing.

Changes to Squid-2.2 ():

        - Removed all SNMP specific ACL code
          SNMP now uses generic squid ACL's
        - Removed view-based access crontrol
        - Cleaned up and simplified SNMP section of squid.conf
        - Changed the SNMP code to use a tree stucture.
        - Added objects to MIB:
                Request Hit Ratio's
                Byte Hit Ratio's
                Number of Clients
        - Changed SNMP Agent to return object instances correctly.
        - Added our own assert() macro so we can use debug() instead of
          printing to stderr.
        - Added eventFreeMemory().
        - Fixed ipcCreate() bug when debug_log has FD <= 2.
        - Changed watchChild() and related code in main.c so that
          Squid can behave more like a proper daemon process.
        - Added 'prefer_direct' option (enabled by default) so that
          people can give parents higher preference than direct.
        - Fixed ipc.c close() bug for async IO. On FreeBSD,
          comm_close() doesn't work for child processes when async IO is
          used.
        - Fixed setting the public key for large ``icons'' (Henrik
          Nordstrom).
        - Rewrote peer digest module to fix memory leaks on reconfigure
          and clean the code. Increased "current" digest version to 5
           ("required" version is still 3). Revised "Peer Select" cache
           manager stats.
        - Added "-k parse" command line option: parses the config file
          but does not send a signal unlike other -k options.
        - Revamped storeAbort() calling. Only store_client.c has all
          the right information to determine if the request should
          be aborted. Now client and server modules just storeUnregister
          without ever needing to call storeAbort.
        - Small change of Squid output for FTP (Andrew Filonov,
          Henrik Nordstrom).
        - clientGetsOldEntry() sends old entry if new request status
          is in the 500-range (Henrik Nordstrom).
        - Changed configure so it works with IRIX6.4 C compiler (broken?)
          option -OPT:fast_io=ON.
        - Fixed comm_connect_addr() non-blocking connections for
          SONY NEWSOS (Makoto MATSUSHITA).
        - Changed "#ifdef __STDC__" to "#if STDC_HEADERS" as recommended
          by autoconf documentation.
        - Fixed client-side cache-control max-age (Henrik Nordstrom).
        - Added a new error page: ERR_SHUTTING_DOWN. fwdStart() returns
          this error if it is called while squid is in the process of
          shutting down.
        - Added support for linuxthreads package under FreeBSD (Tony Finch).
        - Fixed HP-UX StatHist.c assertions by making the "hbase_f"
          functions non-static (Michael Pelletier).
        - Fixed logging of authenticated usernames even if the
          authorization is not cached (Dancer).
        - Fixed pconnPush() bug that prevented holding on to
          persistent connections (Manfred Bathelt).
        - Pid file now rewritten on SIGHUP.
        - Numerous Ident changes:
                - Ident lookups will now be done on demand if you use the
                  'ident' ACL type.
                - The 'ident_lookup on|off' option has been replaced with
                  an access list, so you can do lookups only for some
                  client addresses.
                - Added an 'ident_timeout' option to specifiy the amount
                  of time to wait for an ident lookup.
        - Added a (local) hit rate to mempool metering.
        - FTP Restarts (REST command) is now supported.
        - Check for libintl.a on SCO3.2.
        - Disable poll() on SCO3.2.
        - Numerous Async IO enhancements from Henrik.
        - Removed cache_mem_low and cache_mem_high options (Henrik
          Nordstrom).
        - Replaced 'persistent_client_posts' with 'broken_posts' access
          list.
        - Rewrote the anonymizer.
        - Removed the http_anonymizer option.
        - Added the anonymize_headers option to allow individual
          referencing of headers for addition or removal. See
          'anonymize_headers' in squid.conf for additional
          configuration.
        - Fixed config file parser's handing of optional directives.
          Some people might get new warnings about unknown config
          directives.
        - Added 'myip' ACL type. This is the local IP address for
          connected sockets (Luyer).
        - Fixed parsing of FTP DOS directory listings with spaces
          (Nordstrom).
        - Numerous DELAY_POOL changes/fixes from David Luyer:
                - Makes no-delay neighbors for DELAY_POOLS work by
                  using a fd_set with the connections to no-delay
                  peers marked in it.
                - Makes IP addresses ending in 0 and 255, and
                  network number 255, work with individual and
                  network delay pools (they were previously not
                  permitted, and documented as such).
                - Massive overhaul of delay pools code - dynamically
                  allocated delay pools, as many as required.
                - delayPoolsUpdate stops running if DELAY_POOLS is
                  configured but no delay pools are configured.
                - Initial delay pool levels are now configurable
                  as a percentage of the maximum for the pool in
                  question (used to be all set to 1 second worth
                  of traffic). Pools are restored to this level
                  on reconfiguratoin.
        - Changed storeClientCopy to give a swap-in failure if
          the number of open disk FD's is above the 'max_open_disk_fds'
          limit. Otherwise, a very loaded cache will end up with
          all disk files open for reading, and none for writing.
        - Added lib/inet_ntoa.c from BSD Unix for systems that have
          broken inet_ntoa(). (Erik Hofman).
        - Added more specific FTP error messages for "permission
          denied, "file not found," and "service unavailable."
          (Tony Finch)
        - Added xisspace(), xisdigit(), etc, macros to cast function
          args and eliminate compiler warnings.
        - Fixed case-sensitive comparisons of domain names (Henrik
          Nordstrom).
        - Added proxy-authentication to cachemgr.cgi's requests
          (Henrik Nordstrom).
        - Changed Squid to *truncate* rather than *unlink* purged
          swap files. Can be reversed by undefining
          USE_TRUNCATE_NOT_UNLINK in src/defines.h.
        - Changed internal icon headers to use Cache-control
          Max-age instead of Expires.
        - Changed storeMaintainSwapSpace behavior to be adjusted
          smoothly, instead of discretely, between store_swap_low
          and store_swap_high. This includes the number of
          objects to scan, number to remove, and time until the
          next storeMaintainSwapSpace event.
        - Fixed a quick_abort bug that incorrectly calculated
          content lengths.
        - Added getpwnam() auth module from Erik Hofman.
        - Added 'coredump_dir' option.
        - Fixed a peerDestroy() assertion that required peer->digest
          to be NULL at the end of peerDestroy().
        - configure script now automatically enables dlmalloc for
          Solaris/x86.
        - configure enables poll() on linux 2.2 and later (Henrik).
        - Icon files are now distributed in binary format, install
          will not need to run 'sh' and 'uudecode'.
        - Fixed some bugs with large responses (>READ_AHEAD_GAP) and
          re-forwarding requests and ENTRY_FWD_HDR_WAIT.
          fwdCheckDeferRead() will NOT defer reading if the
          ENTRY_FWD_HDR_WAIT bit is set.
        - Fixed a "F->flags.open" assertion for aborted FTP PUT's.
        - Fixed a (double) cast problem that caused statAvgTick()
          events to be added as fast as possible.
        - Changed httpPacked304Reply() to not include the Content-Length
          header for 304 replies that Squid generates. We used to
          include the length of the cached object, and this broke
          persistent connections.
