Changes with Apache 2.0-dev
  
  *) apr_send{,v}, apr_recv, ap_sendfile API clarification --
     bytes_read/bytes_written is always valid (never -1).  Plus
     some fixes to buff.c to correct problems introduced by the
     errno => apr_status_t changes a while back.  Plus a fix to
     chunked encoding introduced right at the beginning of 2.0.
     [Dean Gaudet]

  *) port mod_rewrite to 2.0. [Paul J. Reder ]

  *) More rigorous checking of Host: headers to fix security problems
     with mass name-based virtual hosting (whether using mod_rewrite
     or mod_vhost_alias).
     [Ben Hyde, Tony Finch]
  
  *) Add back support for UseCanonicalName in  containers.
     [Manoj Kasichainula]

  *) Added APLOG_STARTUP log type.  This allows us to write an error
     message without any of the date and time information.  As a part
     of this change, I also removed all of the calls to fprintf(stderr
     and replaced them with calls to ap_log_error using APLOG_STARTUP
     writing to stderr is no longer portable, because we don't direct 
     stderr to the error log on all platforms.
     [Ryan Bloom] 
 
  *) Convert error logging functions to take errno as an argument.
     This makes our error logs more portable, because some Windows API's 
     don't set errno.  This change allows us to still output a valid
     message on all of our platforms.
     [Ryan Bloom]

  *) mod_mime_magic runs in 2.0-dev now.
     [Paul Reder ]

  *) sendfile has been added to APR.
     [John Zedlewski ]

  *) buff.c has been converted to no longer use errno.
     [Manoj Kasichainula]

  *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
     interface adaption to APR functions did it. [Martin Kraemer]

  *) Support DSOs properly on 32-bit HP-UX 11.0
     [Dilip Khandekar ]

  *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
     [Ralf S. Engelschall]

  *) Cleaned APR build environment integration and bootstrap APR 
     automatically for developers from src/Configure.
     [Ralf S. Engelschall]

  *) Fixed building of src/support/htpasswd.c
     [Ralf S. Engelschall]

  *) When generating the Location: header, mod_speling forgot
     to escape the spelling-fixed uri. (Forw-Port from 1.3)
     [Martin Kraemer]

  *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]

  *) Change all pools to APR contexts.  This is the first step to
     incorporating APR into Apache. [Ryan Bloom]

  *) Move "handler not found" warning message to below the check
     for a wildcard handler.  [Dirk , Roy Fielding]
     PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807

  *) Support line-continuation feature in config.option file and
     allow the loading of multiple option sections at once via
     ``--with-option=,,...''
     [Ralf S. Engelschall]

  *) Rebuilt CVS repository with Apache 1.3.9 as basis.  [Roy Fielding]

Changes with Apache MPM

  *) Implement the APACI --with-option facility 
     (per default used the config.option file).
     [Ralf S. Engelschall]

  *) MPM BEOS port.  [David Reid ]

  *) Start to implement module-defined hooks that are a) fast and b) typesafe.
     Replace pre_connection module call with a register_hook call and
     implement pre_connection as a hook. The intent is that these hooks will
     be extended to allow Apache to be multi-protocol, and also to allow the
     calling order to be specified on a per-hook/per-module basis.
     [Ben Laurie]

  *) Implement mpm_* methods as "modules". Each method gets its own
     subdir in src/modules (eg: src/modules/prefork). Selection
     of method uses Rule MPM_METHOD.  [Jim Jagielski]

  *) Port the hybrid server from the apache-apr repository as
     mpm_mpmt_pthread.  [Manoj Kasichainula]

  *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
     amongst the unix MPMs.

  *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
     signal handling for the new world order.  [Dean Gaudet]

  *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
     of alloc.c for now.  [Dean Gaudet]

  *) Handle partial large writes correctly.  [Ben Laurie]

  *) Eliminate conn_rec's pointer to server. All it knows is the base server
     based on IP/port.  [Ben Laurie]

  *) Port a bunch of modules to the new module structure.
     ["Michael H. Voase" ]

  *) I/O layering and BUFF revamp.  See docs/buff.txt.  [Dean Gaudet]

  *) Basic restructuring to introduce the MPM concept; includes various
     changes to the module API... better described by
     docs/initial_blurb.txt.  [Dean Gaudet]

Changes with Apache pthreads

  *) New buff option added: BO_TIMEOUT. It describes the timeout for
     buff operations (generally over a network).
     [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]

  *) Created http_accept abstraction. Added 4 new functions (not exported):
     init_accept(), begin_accepting_requests(), get_request(), 
     stop_accepting_requests() [Bill Stoddard]

  *) Fix to ap_rprintf call that allows mod_info to work properly.
     [James Morris ]

  *) user and ap_auth_type fields were moved from connection_rec to 
     request_rec. [Ryan Bloom] 

  *) Removed the ap_block_alarms and ap_unblock_alarm calls.  These aren't
     needed in a threaded server.
