New in version 1.23:
 - Fixed CVE-2015-1548, a buffer overflow via snprintf.

New in version 1.22:
 - Don't do TCP_NOPUSH on SSL connections. It doesn't help and causes problems.
 - Use memmove() for self-overlapping string copies instead of strcpy().

New in version 1.21:
 - Disable SSL 3 because of the "poodle" attack.

New in version 1.20:
 - Better handling for very large files.
 - Use TCP_CORK if it's available and TCP_NOPUSH is not.
 - Ignore ECONNABORTED on accept().
 - Removed mailto: link from the default index page.
 - Allow CGIs to provide both Location and Status headers. (A. Skrobov)
 - Better logic for figuring out CGI SERVER_NAME environment variable. (Oleg)
 - Updated for clang, and general cleanup.

New in version 1.19:
 - Prohibit "Host: ." and "Host: .." (David Leadbeater).
 - Use the specified charset in directory listings and errors (Jonas Ohlsson).
 - Close and re-open the log file on SIGHUP. This includes code to chown 
    the log file when starting up as root so that after switching
    uids to nobody (or whatever user you configure) it can still be re-opened.
    And there's also code to tweak the logfile pathname after a chroot so that
    it still works.
 - Generate multiple MIME encodings in the correct order,
    and with the correct separator.
 - Re-wrote the read() and write() loops to handle EINTR and EAGAIN.
 - Save and restore errno in signal handlers.
 - Corrected possible buffer overflow in building CGI 
    environment (Bernhard Reiter).
 - Simplified handling of HAVE_INT64T (Trisk). If this causes problems, e.g. 
    if there are still systems which don't have "long long", we can back out the change.
 - Automatically add no-cache control header on error responses.

New in version 1.18:
 - Added a bunch of MIME types.
 - Allow blank lines in the config file.
 - Digital Unix 4.0d doesn't have int64_t.
 - Use unsigned short consistently for port number.
 - Prohibit slashes in the Host: header (Marcus Breiing).
 - For some reason there was never a timeout on writing the response, only on reading the request; fixed.
 - Don't send Content-Length header on 304 Not Modified responses.
 - Allow user-agent log entries to be up to 200 characters long, instead only of 80.
 - Changed most uses of \r and \n to \015 and \012 (Jens Bauer).
 - Got rid of extra slash in PATH_TRANSLATED (Benedikt Hochstrasser).

New in version 1.17:
 - Simplified the IPv6 ifdefs.
 - Remove /./ in de_dotdot() (Dana Dahlstrom).
 - Added an madvise(MADV_SEQUENTIAL) call for the cases that use mmap().
 - Added .xhtml and .xht to mime_types.txt (suggested by Dave Hodder).
 - Made the list of possible index filenames into an array instead of hard-coded.
 - Added a bunch of syslogs.
 - On generated pages which set BGCOLOR, also set TEXT LINK and VLINK.
 - Added some OpenOffice MIME types (Dave Hodder).

New in version 1.16:
 - Some fixes for unusual cases in the CGI file-descriptor shuffling (Michael Gorlick).
 - On SysV use sigset() instead of signal() (David Koblas).
 - Set up accept filters after listen() (Kris Spinka).
 - Preserve query string when doing a missing-slash directory redirect.
 - New port.h defines for NetBSD.
 - Fix for security hole that exposed contents of .htpasswd in some cases (noticed by zeno@cgisecurity.com).
 - Allow (and ignore) extra fields in .htpasswd files.
 - Added PATH_INFO to CGI environment (Benedikt Hochstrasser).
 - Close log file before running CGI (Damien Miller).
 - Integrated directory lister (Damien Miller).
 - Added a shutdown() call to cgi_interpose_output().
 - Added some Microsoft MIME types (Kevin Day).
 - Use binary search to figure MIME types (suggested by Sascha Schumann and Rob Ekl).
 - Linux's sendfile has a different calling sequence.
 - Set TCP_NOPUSH socket option.
 - Switch htpasswd from using tmpnam to mkstemp.
 - Use memmove instead of memcpy.
 - Fix to de_dotdot (Mark Dunlap).
 - Added portability defines for Digital Unix.
 - Off-by-one error in base-64 decoding (Archie Cobbs).
 - URL-encoding in directory listings.
 - Fix (harmless) subprocess SEGV on null requests (noticed by Tyler Mitchell).
 - Ignore EINTR on select call when doing IPv4 and IPv6 (noticed by Tyler Mitchell).
 - Added -V version flag.
 - Added a timeout on request reading.
 - Corrected some uses of size_t and off_t.
 - Now able to serve files larger than 2GB.
 - Default installation direction is now /usr/local/sbin, not /usr/local/bin.
 - Added a scripts subdirectory with some sample code for FreeBSD systems.
 - Added a -P flag for setting the P3P header.
 - Added a -C config-file option similar to thttpd's.
 - Added flags to specify the SSL certificate file and cipher set.
 - Simplified the OS-detection ifdef maze in port.h (Damien Miller).
 - Split match() into a separate file, like it is in thttpd.
 - Added non-local referer filtering similar to thttpd's.
 - Implemented content-encoding header.
 - Added rudimentary option to set cache-control headers.

New in version 1.15c:
 - Fix for the garbage characters after POST data hack.

New in version 1.15b:
 - Fix syntax oops when SSL is defined.

New in version 1.15:
 - Update SSL support to current version of OpenSSL.
 - Close extraneous file descriptors on CGI calls - from Russell Dill.
 - Hack to deal with garbage characters after POST data generated by some browsers.
 - Use sendfile() if available.
 - Use accept filters if available.

New in version 1.14:
 - Added hack to prevent MSIE 5 from censoring error messages.

 - Documented the -D flag.

New in version 1.13:
 - Added some MIME types to support WAP/WML.
 - Made MIME text character-set an option, with iso-8859-1 the default.

New in version 1.12:
 - Fix for directory indexes on Linux - symlinks were not indexing right 
    due to a bug in Linux's ls.
 - Solaris/SysV fix - it was exitting after serving a single request, due
    to SIGCHLD generating an EINTR.
 - A change in the way wildcard matching works - now a single * only matches 
    strings that don't include a slash. To match entire pathnames including 
    slashes you have to use **.
 - Fix for index.cgi - it was returning the file's contents instead of running it.
 - On systems with IPv6, automatically bind to both v4 and v6 sockets.
 - Added charset=iso-8859-1 to text MIME types.

    gets looked up before the chroot().

New in version 1.03:
 - Bugfix for CGI header parsing 
    if the CGI was sending binary data (e.g. images),
    the result could get truncated or corrupted.
