Changes to squid-2.5.STABLE4 (15 Sep 2003):
	- Lithuanian error messages added to the distribution
	- Bug #660: segfauld if more than one custom deny_info line
	- cache_dir disd documentation cleanup
	- check open of /dev/null to avoid 100% CPU loop in badly
	  configured chroot environments
	- documentation update on uri_whitespace to refer to the correct RFC
	- Bug #655: icmpRecv: recv: (11) Resource temporarily unavailable
	- Bug #683: external_acl does not wait for ident lookups to complete
	- aufs: Fix a minor use-after-free problem which could cause the
	  count of opening filedescriptors to grow larger than it should
	- Syntax changes to make GCC-3.3 accept Squid without complaints
	- Warning if CARP server defined in incorrect load factor order
	- neighbor_type_domain documentation update
	- http_header_access now works when using cache peers
	- high_memory_warning now uses sbrk as fallback mechanism on
	  platforms where neither mallinfo or mstats are available.
	- hosts_file now handles comments at the end of lines correcly
	- storeCheckCachable() Stats corrected for release_request and
	  wrong_content_length.
	- cachePeerPingsSent MIB type corrected
	- unused minimum_retry_timeout directive removed
	- Bug #702: ERR_TO_BIG spanish translation
	- Bug #705: Memory leak on deny_info TCP_RESET
	- Code cleanup to fix compile error in httpHeaderDelById
	- Bug #699: Host header now forwarded exactly where it was in the
	  original request to work around certain broken firewalls or
	  load balancers which fail if this header is too far into the
	  request headers.
	- Bug #704: Memory leak on reply_body_max_size
	- Bug #686: requests denied due to http_reply_access are now
	  logged with TCP_DENIED (instead of TCP_MISS, etc).
	- Bug #708: ie_refresh now sends no-cache to have the reload
	  request propagate properly in cache meshes
	- Bug #700: Crashes related to ftpTimeout: timeout in SENT_PASV state
	- Bug #709: cbdata.c:186: "c->valid" assertion due to peer
	  digest not found
	- Bug #710: round-robin cache_dir selection incorrectly
	  compares max-size.
	- Statistics corrections in HTTP header statitics
	- QUICKSTART cleanups
	- Bug #715: statCounter.syscalls.disk counters treated
	  inconsistently.  Now increment the counters in AUFS
	  functions and for unlinkd.
	- Improvements to the (experimental) COSS storage scheme.
	- Bug #721: User name field in access.log sometimes blank
	- Bug #94: assertion failed: http.c: "-1 == cfd ||
	  FD_SOCKET == fd_table[cfd].type"
	- Bug #716: assertion failed: client_side.c:1478: "size > 0"
	- Bug #732: aufs calculates number of threads and limits wrongly
	- Bug #663: Username not logged into access.log in case of /407
	- Bug #267: Form POSTing troubles with NTLM authentication
	  and occationally in differen other error conditions.

	  passwd file
	- Bug #267, #757: POST with NTLM stops after persistent connection
	  timeout
	- Bug #742: Wrong status code on access denials if delay_access
	  is used. Most notably 407 instead of 403 could be returned.
	- Bug #763: segfault if using ntlm in http_reply_access
	- Bug #638: assertion error if using proxy_auth in delay_access
	- Bug #756: segmentation fault if using ntlm proxy_auth in delay_access
	- The issue of reply_body_max_size limiting the size of error
	  messages no longer applies.
	- external_acl_type concurrency= option renamed to children= to
	  prepare for Squid-3 upgrades. Old syntax still accepted for the
	  duration of the Squid-2.5 release.
	- number of filedescriptors rounded down to an even multiple of 64
	  to work around issues in certain libc implementations.
	- winbind helpers less noisy in cache.log on restarts/shutdown.
	- Squid now automatically restarts helpers if too many of them
	  have crashed.
