-Changes with Apache 2.0a7
-  *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
-     [Mike Abbott <mja@sgi.com>]
+Changes with Apache 2.0a8
+  *) Add a directive to mod_mime so that filters can be associated with
+     a given mime-type.
+     [Ryan Bloom]
+
+  *) Get multi-views working again.  We were setting the path_info
+     field incorrectly if we couldn't find the specified file.
+     [Ryan Bloom]
 
-  *) Remove ap_send_fb.  This is no longer used in Apache, and it doesn't
-     make much sense, because Apache uses buckets instead of BUFFs now.
+  *) Fix 304 processing.  The core should never try to send the headers
+     down the filter stack.  Always, just setup the table in the request
+     record, and let the header filter convert it to data that is ready
+     for the network.
      [Ryan Bloom]
 
-  *) send_the_file now falls back to a read/write loop on platforms that
-     do not have sendfile.
-     [Ryan Bloom and Brian Havard]
+  *) More fixes for the proxy.  There are still bugs in the proxy code,
+     but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
+     successfully.
+     [Ryan Bloom]
 
-  *) Install apachectl correctly, and substitute the proper values so
-     that it works again.  [Ryan Bloom]
+  *) Fix params for apr_getaddrinfo() call in connect proxy handler.
+     [Chuck Murcko]
 
-  *) Better(??) handle platforms that lack sendfile().
-     [Jim Jagielski]
+  *) APR: Add new apr_getopt_long function to handle long options.
+     [B. W. Fitzpatrick <fitz@red-bean.com>]
 
-  *) APR now has UUID generation/formatting/parsing support.
-     [Greg Stein]
+  *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
+     Add generic apr_create_socket().  Add apr_getaddrinfo() for doing
+     hostname resolution/address string parsing and building
+     apr_sockaddr_t.  Add apr_get_sockaddr() for getting the address
+     of one of the apr_sockaddr_t structures for a socket.  Change
+     apr_bind() to take apr_sockaddr_t.  [David Reid and Jeff Trawick]
 
-  *) Begin the http_filter.  This is an input filter that understands
-     the absolute basic amount required to parse an HTTP Request.  The
-     goal is to be able to split headers from request body before passing
-     the data back to the other filters.
+  *) Remove the BUFF from the HTTP proxy.  This is still a bit ugly, but
+     I have proxied pages with it, cleanup will commence soon.
      [Ryan Bloom]
 
-  *) Bring forward from 1.3.13 the config directory implementation
-     [Jim Jagielski]
+  *) Make the proxy work with filters.  This isn't perfect, because we
+     aren't dealing with the headers properly.  [Ryan Bloom]
 
-  *) install apxs if it is created
+  *) Do not send a content-length iff the C-L is 0 and this is a head
+     request.  [Ryan Bloom]
+
+  *) Make cgi-bin work as a regular directory when using mod_vhost_alias
+     with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
+
+  *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
+
+  *) Get the default_handler to stop trying to deal with HEAD requests.
+     The idea is to let the content-length filter compute the C-L before
+     we try to send the data.  If we can get the C-L correctly, then we
+     should send it in the HEAD response.
      [Ryan Bloom]
 
-  *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
-     conversions.  [William Rowe]
+  *) The Header filter can now determine if a body should be sent based
+     on r->header_only.  The general idea of this is that if we delay
+     deciding to send the body, then we might be able to compute the
+     content-length correctly, which will help caching proxies to cache
+     our data better.  Any handler that doesn't want to try to compute
+     the content-length can just send an EOS bucket without data and
+     everything will just work.
+     [Ryan Bloom]
 
-  *) Now that we have ap_add_input_filter(), rename ap_add_filter() to 
-     ap_add_output_filter().  [Jeff Trawick]
+  *) Add the referer to the error log if one is available.
+     [Markus Gyger <mgyger@itr.ch>]
 
-  *) Multiple build and configuration fixes
-    Build process:
+  *) Mod_info.c has now been ported to Apache 2.0.  As a part of this
+     change, the root of the configuration tree has been exposed to modules
+     as ap_conftree.

-      -replace $foobar by $(foobar) to be usefull in the makefile

-  *) Fix a bug where a client which only sends \n to delimit header
-     lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED 
-     message.  Start working on ebcdic co-existance with input 
-     filtering.
-     [William Rowe, Greg Ames]
+  *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
+     a bogus bytes-sent value when the only thing being sent was trailers
+     and writev() returned an error (or EAGAIN).  [Jeff Trawick]
 
-  *) If mod_so is enabled in the server always create libexec, even
-     if there are no modules installed in this directory.  This is a
-     requirement for APXS to work correctly.
+  *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again.  This uses the
+     hints file to determine which platforms define
+     SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
      [Ryan Bloom]
 
-  *) Connection oriented output filters are now stored in the 
-     conn_rec instead of the request_rec.  This allows us to add the
-     output filter in the pre-connection phase instead of the
-     post_read_request phase, which keeps us from trying to write an
-     error page before we have a filter to write to the network.
-     [Ryan Bloom, Jeff Trawick, and Greg Ames]
+  *) APR: add apr_get_home_directory()  [Jeff Trawick]
 
-  *) Cleaning up an mmap bucket no longer deletes the mmap.  An
-     mmap can be used across multiple buckets (default_handler with
-     byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
-     the mmap itself can't be associated with the bucket.
-     [Jeff Trawick]
+  *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
 
-  *) Add .dll caching directive ISAPICacheFile to mod_isapi.
-     [William Rowe]
+  *) Not all platforms have INADDR_NONE defined by default.  Apache
+     used to make this check and define INADDR_NONE if appropriate,
+     but APR needs the check too, and I suspect other applications will
+     as well.  APR now defines APR_INADDR_NONE, which is always a valid
+     value on all platforms.
+     [Branko Èibej <brane@xbc.nu>]
 
-  *) Radical surgery to improve mod_isapi support under Win32.
-     Includes a number of newer ServerSupportFunction calls, support
-     for ReadClient (in order to retrieve POSTs greater than 48KB),
-     and general bug fixes to more reliably load ISAPI .dll's and
-     prevent leaking handle resources.  Note: There are still 
-     discrepancies between IIS's and Apache's ServerVariables, and
-     async calls are still not supported.  Additional warnings are
-     logged to facilitate debugging of unsupported ISAPI calls.
-     [William Rowe]
+  *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
+     [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
 
-  *) Add input filtering to Apache.  The basic idea for the input
-     filters is the same as the ideas for output filters.  The biggest
-     difference is that instead of calling ap_pass_brigade, ap_get_brigade
-     should be called, and the order of execution for the filter itself is
-     different.  When writing an output filter, a brigade is passed in,
-     and filters operate directly on that brigade, when done, they call
-     ap_pass_brigade.  Input filters are the exact opposite.  Because input
-     is not a push operation, filters first call ap_get_brigade.  When this
-     function returns, the input filter will be left with a valid brigade.
-     The input filter should then operate on the brigade, and return.
+  *) Relax the syntax checking of Host: headers in order to support
+     iDNS. PR#6635 [Tony Finch]
+
+  *) When reading from file buckets we convert to an MMAP if it makes
+     sense.  This also simplifies the default handler because the
+     default handler no longer needs to try to create MMAPs.
+     [Ryan Bloom]
+
+  *) BUFF has been removed from the main server.  The BUFF code will remain
+     in the code until it has been purged from the proxy module as well.
      [Ryan Bloom]
 
-  *) Fix building on BSD/OS using its native make. The build system
-     falls back to the BSD .include directive on that host platform.
+  *) Byteranges have been completely re-written to be a filter.  This
+     has been tested, and I believe it is working correctly, but it could
+     doesn't work for the Adobe Acrobat plug-in.  The output almost matches
+     the output from 1.3, the only difference being that 1.3 includes
+     a content-length in the response, and this does not.
+     [Ryan Bloom]
+
+  *) APR read/write functions and bucket read functions now operate
+     on unsigned integers, instead of signed ones.  It doesn't make
+     any sense to use signed ints, because we return the error codes,
+     so if we have an error we should report 0 bytes read or written.
+     [Ryan Bloom]
+
+  *) Always compute the content length, whether it is sent or not.
+     The reason for this, is that it allows us to correctly report
+     the bytes_sent when logging the request.  This also simplifies
+     content-length filter a bit, and fixes the actual byte-reporing
+     code in mod_log_config.c
+     [Ryan Bloom]
+
+  *) Remove AP_END_OF_BRIGADE definition.  This does not signify what
+     it says, because it was only used by EOS and FLUSH buckets.  Since
+     neither of those are required at the end of a brigade, this was
+     really signifying FLUSH_THE_DATA, but that can be determined better
+     by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH.  EOS and FLUSH
+     buckets now return a length of 0, which is actually the amount of data
+     read, so they make more sense.
+     [Ryan Bloom]
+
+  *) Allow the core_output_filter to save some data past the end of a
+     request.  If we get an EOS bucket, we only send the data if it
+     makes sense to send it.  This allows us to pipeline request
+     responses.  As a part of this, we also need to allocate mmap
+     buckets out of the connection pool, not the request pool.  This
+     allows the mmap to outlive the request.
+     [Ryan Bloom]
+
+  *) Make blocking and non-blocking bucket reads work correctly for
+     sockets and pipes.  These are the only bucket types that should
+     have non-blocking reads, because the other bucket types should
+     ALWAYS be able to return something immediately.
+     [Ryan Bloom]
+
+  *) In the Apache/Win32 console window, accept Ctrl+C to stop the
+     server, but use Ctrl+Break to initiate a graceful restart
+     instead of duplicating behavior. [John Sterling]
+
+  *) Patch mod_autoindex to set the Last-Modified header based on
+     the directory's mtime, and add the ETag header.  [William Rowe]
+
+  *) Merge the 1.3 patch to add support for logging query string in
+     such a way that "%m %U%q %H" is the same as "%r".
+     [Bill Stoddard]
+
+  *) Port three log methods from mod_log_config 1.3 to 2.0:
+     CLF compliant '-' byte count, method and protocol.
+     [Bill Stoddard]
+
+  *) Add a new LogFormat directive, %c, that will log connection
+     status at the end of the response as follows:
+     'X' - connection aborted before the response completed.
+     '+' - connection may be kept-alive by the server.
+     '-' - connection will be closed by the server.
+     [Bill Stoddard]
+
+  *) Expand APR for WinNT to fully accept and return utf-8 encoded
+     Unicode file names and paths for Win32, and tag the Content-Type
+     from mod_autoindex to reflect that charset if the the feature
+     macro APR_HAS_UNICODE_FS is true.  [William Rowe]
+
+  *) Compute the content length (and add appropriate header field) for
+     the response when no content length is available and we can't use
+     chunked encoding.  [Jeff Trawick]
+
+  *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
+     so that content input filters get dechunked data when using
+     the default handler. Also removed REQUEST_CHUNKED_PASS.
      [Sascha Schumann]
 
-  *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
-     SHA1 and plaintext password encodings.  Make feature tests a
-     bit more flexible.  [William Rowe]
-
-  *) Charset translation: mod_charset_lite handles output content 
-     translation in a filter.  mod_charset_lite no longer ignores 
-     subrequests.  A bunch of cruft related to BUFF's support for
-     translating response bodies was removed.  [Jeff Trawick]
-
-  *) Move the addition of the CORE filter to the post_read_request
-     hook in http_core.c.  This removes the need to add the filter in
-     multiple places and allows for an SSL module to be added much
-     simpler. [Ryan Bloom]
-
-  *) Fix a security problem that affects certain configurations of
-     mod_rewrite. If the result of a RewriteRule is a filename that
-     contains expansion specifiers, especially regexp backreferences
-     $0..$9 and %0..%9, then it may be possible for an attacker to
-     access any file on the web server. [Tony Finch]
-
-  *) Fix a bug where errors that are detected during early request parsing
-     don't produce visible HTTP error messages at the browser, because
-     the core_filter wasn't present.  [Greg Ames]
-
-  *) Provide apr_socklen_t as a portability aid. 
-     [Victor  J. Orlikowski]
-
-  *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
-     as well as a comment arg to the add, adduser and update cmds.
-     update allows the user to clear or preserve pw/groups/comment.
-     Fixed a bug in dbmmanage that prevented the check option from 
-     parsing a password followed by :group... text.  Corrected the
-     seed calcualation for Win32 systems, and added -lsdbm support.
-     [William Rowe]
+  *) Add mod_ext_filter as an experimental module.  This module allows
+     the administrator to use external programs as filters.  Currently,
+     only filtering of output is supported.  [Jeff Trawick]
 
-  *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
-     [William Rowe]
+  *) Most Apache functions work on EBCDIC machines again, as protocol
+     data is now translated (again).  [Jeff Trawick]
 
-  *) Avoid a segfault when parsing .htaccess files.  An 
-     uninitialized tree pointer was passed to ap_build_config().
-     [Jeff Trawick]
+  *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
+     the EBCDIC support.  They are noops on ASCII machines, so this
+     type of translation doesn't have to be surrounded by #ifdef
+     CHARSET_EBCDIC.  [Jeff Trawick]
 
-  *) Change the way that inet_addr & inet_network are checked for
-     in APR's configure process to allow BeOS BONE to correctly
-     find them. With this change BeOS BONE now builds from source
-     with no problems.  [David Reid]
-
-  *) Fix a bug in apr_create_process() for Unix.  The NULL signifying
-     the end of the parameters to execve() was stored in the wrong
-     location, overlaying the storage beyond the newargs[] array and 
-     also passing uninitialized storage to execve(), which would 
-     sometimes fail with EFAULT.  [Jeff Trawick]
-
-  *) Fix a bug parsing configuration file containers.  With a sequence
-     like this in the config file
-
-       <IfModule mod_kilroy.c>
-       any stuff
-       </IfModule>
-       <IfModule mod_lovejoy.c>
-       (blank line)
-       any stuff
-       </IfModule>
-
-     the second container would be terminated at the blank line due to
-     sediment in the buffer from reading the prior </IfModule> and an 
-     error message would be generated for the real </IfModule> for the
-     second container.  Also due to this problem, any two characters 
-     could be used for "</" in the close of a container.  
-     [Jeff Trawick]
+  *) Fix mod_include.  tag commands work again, and the server will
+     send the FAQ again.  This also allows mod_include to set aside
+     buckets that include partial buckets.
+     [Ryan Bloom and David Reid]
+
+  *) Add suexec support back.  [Manoj Kasichainula]
 
-  *) ap_add_filter prototype changed to remove the ctx pointer.  The
-     pointer still remains in the filter structure, but it can not be
-     a part of the ap_add_filter prototype.  The reason is that when
-     the core uses AddFilter to add a filter to the stack it doesn't
-     know how to allocate the ctx pointer, or even how much memory should
-     be allocated.  The filters will have to be responsible for allocating
-     the ctx memory when they need it.
+  *) Lingering close now uses the socket directly instead of using
+     BUFF.  This has been tested, but since all we can tell is that it
+     doesn't fail, this needs to be really hacked on.
      [Ryan Bloom]
 
-  *) Add an AddFilter directive.  This directive takes a list of filters
-     that should be activated for the requested resource.
+  *) Allow filters to modify headers and have those headers be sent to
+     the client.  The idea is that we have an http_header filter that
+     actually sends the headers to the network.  This removes the need
+     for the BUFF to send headers.
      [Ryan Bloom]
 
-  *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
-     some other platforms).  [Jeff Trawick]
+  *) Charset translation: mod_charset_lite handles translation of
+     request bodies.  Get rid of the xlate version of ap_md5_digest()
+     since we don't compute digests of filtered (e.g., translated)
+     response bodies this way anymore.  (Note that we don't do it at
+     all at the present; somebody needs to write a filter to do so.)
+     [Jeff Trawick]
+
+  *) Input filters and ap_get_brigade() now have a input mode parameter
+     (blocking, non-blocking, peek) instead of a length parameter.
+     [hackathon]
+
+  *) Update the mime.types file to the registered media types as
+     of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
+     Tony Finch]
+
+  *) Namespace protect some macros declared in ap_config.h
+     [Ryan Bloom]
+
+  *) Support HTTP header line folding with input filtering.
+     [Greg Ames]
+
+  *) Mod_include works again.  This should still be re-written, but at
+     least now we can serve an SHTML page again.
+     [Ryan Bloom]
 
-  *) Modify mod_include to be a filter.  Currently, it has only been tested
-     on actual files, but it should work for CGI scripts too.
+  *) Begin to remove BUFF from the core.  Currently, we keep a pointer
+     to both the BUFF and the socket in the conn_rec.  Functions that
+     want to use the BUFF can, functions that want to use the socket,
+     can.  They point to the same place.
      [Ryan Bloom]
 
-  *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
-     writes.  apr_flush() for Unix: handle interrupted writes.
+  *) apr_psprintf doesn't understand %lld as a format.  Make it %ld.
+     [Tomas "Ögren" <stric@ing.umu.se>]
+
+  *) APR pipes on Unix and Win32 are now cleaned up automatically when the
+     associated pool goes away.  (APR pipes on OS/2 were already had this
+     logic.)  This resolvs a fatal file descriptor leak with CGIs.
      [Jeff Trawick]
 
-  *) NameVirtualHost can now take "*" as an argument instead of
-     an IP address. This allows you to create a purely name-based
-     virtual hosting server that does not have any IP addresses in
-     the configuration file and which ignores the local address
-     of any connections. PR #5595, PR #4455 [Tony Finch]
+  *) The final line of the config file was not being read if there was
+     no \n at the end of it.  This was caused by apr_fgets returning
+     APR_EOF even though we had read valid data.  This is solved by
+     making cfg_getline check the buff that was returned from apr_fgets.
+     If apr_fgets return APR_EOF, but there was data in the buf, then we
+     return the buf, otherwise we return NULL.
+     [Ryan Bloom]
+
+  *) Piped logs work again in the 2.0 series.
+     [Ryan Bloom]
+
+  *) Restore functionality broken by the mod_rewrite security fix:
+     rewrite map lookup keys and default values are now expanded
+     so that the lookup can depend on the requested URI etc.
+     PR #6671 [Tony Finch]
 
-  *) Fix some compile warnings in mod_mmap_static.c
-     [Mike Abbott <mja@sgi.com>]
+  *) Tighten up the syntax checking of Host: headers to fix a
+     security bug in some mass virtual hosting configurations
+     that can allow a remote attacker to retrieve some files
+     on the system that should be inaccessible. [Tony Finch]
 
-  *) Fix chunking problem with CGI scripts.  The general problem was that
-     the CGI modules were adding an EOS bucket and then the core added an
-     EOS bucket.  The chunking filter finalizes the chunked response when it
-     encounters an EOS bucket.  Because two EOS buckets were sent, we
-     finalized the response twice.  The fix is to make sure we only send one
-     EOS, by utilizing a flag in the request_rec.
+  *) Add a pool bucket type.  This bucket is used for data allocated out
+     of a pool.  If the pool is cleaned before the bucket is destroyed, then
+     the data is converted to a heap bucket, allowing it to survive the
+     death of the pool.

-  *) apr_put_os_file() now sets up the unget byte appropriately on Unix
-     and Win32.  Previously, the first read from an apr_file_t set up via
-     apr_put_os_file() would return a '\0'.  [Jeff Trawick]
+  *) Add a flush bucket.  This allows modules to signal that the filters
+     should all flush whatever data they currently have.  There is no way
+     to actually force them to do this, so if a filter ignores this bucket,
+     that's life, but at least we can try with this.
+     [Ryan Bloom]
 
-  *) Mod_cgid now creates a single element bucket brigade, with a pipe
-     bucket, instead of using BUFF's and ap_r*.
+  *) Add an output filter for sub-requests.  This filter just strips the
+     EOS bucket so that we don't confuse the main request's core output
+     filter by sending multiple EOS buckets.  This change also makes sub
+     requests start to send EOS buckets when they are finished.
      [Ryan Bloom]
 
-  *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
-     [Mike Abbott <mja@sgi.com>]
+  *) Make ap_bucket_(read|destroy|split|setaside) into macros.  Also
+     makes ap_bucket_destroy a return void, which is okay because it
+     used to always return APR_SUCCESS, and nobody ever checked its
+     return value anyway.
+     [Cliff Woolley <cliffwoolley@yahoo.com>]
 
-  *) Remove ap_bopenf from buff code.  This required modifying the file_cache
-     code to use APR file's directly instead of going through BUFFs.
+  *) Remove the index into the bucket-type table from the buckets
+     structure.  This has now been replaced with a pointer to the
+     bucket_type.  Also add some macros to test the bucket-type.
      [Ryan Bloom]
 
-  *) Fix compile break on some platforms for mod_mime_magic.c
-     [John K. Sterling <sterling@covalent.net>]
+  *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
+     for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
+     and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
+     All _VAR_ flavors changes to _DATA to be absolutely clear.
+     [William Rowe]
 
-  *) Fix merging of AddDefaultCharset directive.
-     PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
+  *) Add support for /, //, //servername and //server/sharename
+     parsing of <Directory> blocks under Win32 and OS2.
+     [Tim Costello, William Rowe, Brian Harvard]
 
-  *) Minor revamp of the rlimit sections of code. We now test
-     explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
-     is now "available" even if the platform doesn't support
-     the rlimit family (it's just a noop though). [Jim Jagielski]
+  *) Remove the function pointers from the ap_bucket type.  They have been
+     replaced with a global table.  Modules are allowed to register bucket
+     types and use then use those buckets.
+     [Ryan Bloom]
 
-  *) Migrate the pre-selection of which MPM to use for specific
-     platforms to hints.m4, which contains (or should contain)
-     all platform specific "hints". [Jim Jagielski]
+  *) mod_cgid: In the handler, shut down the Unix socket (only for write)
+     once we finish writing the request body to the cgi child process;
+     otherwise, the client doesn't hit EOF on stdin.  Small request bodies
+     worked without this change (for reasons I don't understand), but large
+     ones didn't.  [Jeff Trawick]
 
-  *) Remove IOLs from Apache.  With filtering, IOLs are no longer necessary
+  *) Remove file bucket specific information from the ap_bucket type.
+     This has been moved to a file_bucket specific type that hangs off
+     the data pointer in the ap_bucket type.
      [Ryan Bloom]
 
-  *) Add tables with non-string/binary values to APR.
-     [Ken Coar]
+  *) Input filtering now has a third argument.  This is the amount of data
+     to read from lower filters.  This argument can be -1, 0, or a positive
+     number.  -1 means give me all the data you have, I'll deal with it and
+     let you know if I need more.  0 means give me one line and one line
+     only.  A positive number means I want no more than this much data.
 
-  *) Fix some bad calls to ap_log_rerror() in mod_rewrite. 
-     [Jeff Trawick]
+     Currently, only 0 and a positive number are implemented.  This allows
+     us to remove the remaining field from the conn_rec structure, which
+     has also been done.
+     [Ryan Bloom]
+
+  *) Big cleanup of the input filtering.  The goal is that http_filter
+     understands two conditions, headers and body.  It knows where it is
+     based on c->remaining.  If c->remaining is 0, then we are in headers,
+     and http_filter returns a line at a time.  If it is not 0, then we are
+     in body, and http_filter returns raw data, but only up to c->remaining
+     bytes.  It can return less, but never more.
+     [Greg Ames, Ryan Bloom, Jeff Trawick]
+
+  *) mod_cgi: Write all of the request body to the child, not just what
+     the kernel would accept on the first write.  [Jeff Trawick]
+
+  *) Back out the change that moved the brigade from the core_output_filters
+     ctx to the conn_rec.  Since all requests over a given connection
+     go through the same core_output_filter, the ctx pointer has the
+     correct lifetime.
+     [Ryan Bloom]
+
+  *) Fix another bug in the send_the_file() read/write loop. A partial
+     send by apr_send would cause unsent data in the read buffer to
+     get clobbered. Complete making send_the_file handle partial
+     writes to the network.
+     [Bill Stoddard]
+
+  *) Fix a couple of type fixes to allow compilation on AIX again
+     [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
 
-  *) Update PCRE to version 3.2.  [Ryan Bloom]
+  *) Fix bug in send_the_file() which causes offset to be ignored
+     if there are no headers to send.
+     [Bill Stoddard]
 
-  *) Change the way buckets' destroy functions are called so that
-     they can be more directly used when changing the type of a
-     bucket in place. [Tony Finch]
+  *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
+     filter. Useful for supporting Windows 9* with a binary
+     compiled on Windows NT.
+     [Bill Stoddard]
 
-  *) Add generic support for reference-counting the resources used by
-     buckets, and alter the HEAP and MMAP buckets to use it. Change
-     the way buckets are initialised to support changing the type of
-     buckets in place, and use it when setting aside TRANSIENT buckets.
-     Change the implementation of TRANSIENT buckets so that it can be
-     mostly shared with IMMORTAL buckets, which are now implemented.
