-December 24 1998, Version 3.0.6
-- Fix GetImageSize() to work with non-standard jpg images
-- Add Mersenne Twister functions (mt_rand, mt_srand, etc)
-- Add str_replace() function
-- Add chunk_split() function
-- Fixed a bug in the memory limit code, in cases where $php_errormsg was
-  also used.
-- Add iptcparse() function
-- Adobe FDF supported
-- getallheaders() NULL string fix <michale@utko.fee.vutbr.cz>
-- Add all configuration directives to phpinfo() page
-- Functions pack() and unpack() rewritten to be binary and buffer overrun
-  safe and behave like the Perl functions for all implemented format codes.
-- Ensured that msql_error() will not return error messages generated by
-  previously-run scripts.
-- Add base_convert() function
-- Make sprintf() and printf() output binary safe
-- Made gzgetc binary safe
-- Add convert_cyr_string() and quoted_printable_decode() functions
-- Fix ldap_free_result() core dump bug
-- Add support for current OpenLDAP-2.0-devel library
-- Add php3_asp_tags directive so it can be set from Apache config files
-- Added UTF-8 support in the XML extension
-- Make rand(min,max) safer on older platforms where the low-order bits have 
-  short cycles.
-- Added new pdf (Portable Document Format) module
-- Added an XML parsing extension using James Clark's "expat" library
-- Optimized parts of the token cache code.
-- Terminate on out-of-memory errors.  Until now, PHP could crash in out of
-  memory situations (clean-up, no real effect).
-- Unterminated comments in include files were being reported with the wrong line
-  number.  Fixed.
-- Added ImageCopy() and ImageColorDeallocate(). ImageCopy() is about
-  20% faster than ImageCopyResized(). ImageColorDeallocate() marks
-  palette entries free for reuse (by <mka@satama.com>).
-- In the CGI version, it was impossible to access resources (e.g. SQL links,
-  images) from user-defined shutdown functions.  Fixed.
-- Added optional third parameter to strpos() to specify the offset to
-  start searching from.
-- Fixed a crash bug in unset() when unsetting illegal variables (rare).
-- Made ImageInterlace and ImageTransparentColor parameters optional, and made
-  them return the current/new settings.
-- Optimized GetImageSize() <thies@digicol.de>.
-- Made odbc_autocommit() without args return status
-- Added connect workaround for OpenLink ODBC
-- Added minimal InterBase support. Tested only on 4.0 & Linux.
-- Fixed some memory leaks and bogus error messages in the URL handler of
-  the various file open functions.  Should only affect error handling
-  in bad URLs.
-
-October 5 1998 Version 3.0.5
-- mysql_field_flags now reports all MySQL flags and the result is suitable
-  for automatic parsing. Compatibility warning: The result format has
-  changed. If you have scripts parsing the result of this function, you
-  may need to adapt them.
-- Made nl2br() binary safe (not that it's of much use).
-- Fixed a bug in the API function getThis().  It affected mostly the dir
-  functions, if nested within objects.
-- Fixed a problem in require() in conjunction with switch(), and in some other
-  cases.  Also fixed an identical problem with the call_user_function() API
-  function.
-- Removed -lpthread when compiling with MySQL support.  It caused various
-  serious problems when compiled into Apache.
-- Add serialize() and unserialize() functions from jkl@njet.net
-- Fix in_addr_t check for systems with in_addr_t in netinet/in.h
-- Add atan2() function
-
-September 22 1998 Version 3.0.4
-- Added uksort() - array key sort using a user defined comparison function.
-- Added 'j' support to date() - generates the day of the month, without
-  possible leading zeros.
-- Added support for multiple crypt() encryptions if the system supports it
-- Added optional support for ASP-style <% %> and <%= tags
-- Fixed data loss problems with very large numeric array indices on 64-bit
-  platforms (e.g. DEC UNIX).
-- 2 cursor_type parameters for ifx_query() and ifx_prepare changed
-  to 1 (bitmask). Added a few constants for use in Informix module.
-- Added php3.ini option ifx.charasvarchar. If set, trailing blanks
-  are stripped from fixed-length char columns. (Makes life easier
-  for people using Informix SE.)
-- Static SNMP module which compiles with ucd-snmp 3.5.2
-- fixed imap_header & header_info from crashing when a header line
-  is > 1024 characters.
-- Added patch for rfc822_parse_adr to return an array of objects instead 
-  of a single object. 
-- Informix Online 7.x & SE 7.x support now fairly complete and stable
-- Add dbase_get_record_with_names() function
-- Added a special case for open_basedir. When open_basedir is set to "."
-  the directory in which the script is stored will be used as basedir.
-- Include alloca.c in the distribution for platforms without alloca().
-- Improved stripping of URL passwords from error messages - the length of the
-  username/password isn't obvious now, and all protocols are handled properly
-  (most importantly, http).
-- Copying objects that had member functions with static variables produced
-  undetermined results.  Fixed.
-- Added function lstat() and cleaned up the status functions,
-  added tests for file status functions (this may break on some plattforms)
-- Fixed is_link() - it was returning always false.
-- Fixed apache_note() - it was corrupting memory.
-- New Function.  void get_meta_tags(string filename);  Parses filename until
-  closing head tag and turns all meta tags into variables prefixed with 'meta_'.
-  The below meta tag would produce $meta_test="some string here"
-	<meta name="test" content="some string here">
-- Generalized some internal functions in order to better support calling
-  user-level functions from C code.  Fixes a few sporadic problems related
-  to constructors inside eval() and more.
-- Fixed an endless loop in explode(), strstr() and strpos() in case of an
-  invalid empty delimiter.
-- rand() now accepts two optional arguments, which denote the requested range
-  of the generated number.  E.g., rand(3,7) would generate a random number
-  between 3 and 7.
-- Added M_PI constant.
-- Added deg2rad() and rad2deg() for converting radians<->degrees.
-- ImageArc() misbehaved when given negative angles, fixed.
-- Fixed a bug in ereg() that may have caused buglets under some circumstances.
-- Added imap_status
-- Shutdown functions, registered via register_shutdown_function(), could never
-  generate output in the Apache module version.  Fixed.
-- Brought IMAP docs into sync with acutal imap code
-- imap_fetchstructure now takes in optional flags 
-- Fix potential core dumps in imap_append and imap_fetchtext_full
-- Fix problem in SetCookie() function related to long cookies
-- Add uasort() function to go along with usort (like sort() and asort())
-- Add port number to Host header as per section 14.23 of the HTTP 1.1 RFC
-- Fix imap_reopen to only take 2 arguments with an optional 3rd flags arg
-- Add optional 2nd argument to imap_close
-- Add CL_EXPUNGE flag to imap_open() flags
-- Fix 4th arg on imap_append().  It was getting converted to a long by mistake.
-- Fix shutdown warning in the LDAP module
-- *COMPATIBILITY WARNING* imap_fetchstructure() "parametres" object and property
-  name changed to "parameters" to match the documentation and to be consistent
-  with the rest of the API.
-- Delete uploaded temporary files automatically at the end of a request
-- Add upload_max_filesize and correponsing php3_upload_max_filesize directive
-  to control the maximum size of an uploaded file.  Setting this to 0 would
-  completely eliminate file uploads.
-- Force $PHP_SELF to PATH_INFO value when running in CGI FORCE_CGI_REDIRECT mode
-- Add apache_lookup_uri() function which does an internal sub-request lookup
-  and returns an object containing the request_rec fields for the URI.  (Yes,
-  you have to be a bit of a gearhead to figure this one out)
-- Fix a few signed char problems causing functions like ucfirst() not to work
-  correctly with non-English charsets
-- md5() function not binary safe - fixed
-
-August 15 1998 Version 3.0.3
-- Changed the name of fopen_basedir to open_basedir, to be a little more
-  accurate about what it does.
-- Added Hyperwave module
-- Added config-option (php3_)enable_dl <on/off>. This enables/disables the
-  dl() function.  In safe-mode dl() is always disabled.
-- Auto-prepended files were crashing under some circumstances - fixed.
-- Win32 mail fixes provided by walton@nordicdms.com
-- Comparing between arrays and/or objects now generates a warning (it always
-  returns false, as it used to;  no comparison is made)

-  appear twice under certain circumstances.
-- Fix bug in filetype() function related to symlinks
-- Started integrating Informix SE support to PHP configure/makefile setup.
-- gdttf roundoff fixes from ellson@lucent.com
-- Added initial Informix SE support files from Danny Heijl - This code still
-  needs to be integrated into the PHP configure/makefile setup and the code
-  itself needs more work.
-- return in the global scope now terminates the execution of the current file.
-- Added the ability to register shutdown function(s), via
-  register_shutdown_function($function_name).
-- Clean up const warnings

-- On systems without strerror use Apache version if compiling as Apache module
-- The PHP start tag was being ignored under some circumstances - fixed.
-- The db, dbase and filepro functions are now Safe-Mode aware.
-- Added config-option (php3_)fopen_basedir <path>. This limits the directory-
-  tree scripts can open files in to <path>.
-- Fixed pg_loreadall that didn't always return all the contents in a PostgreSQL
-  large object. Also, doesn't pass through anything if method is HEAD.
-- configure fix to create target Apache module dir
-- Fix core dump in imageTTFtext() function
-- Added static IMAP support
-- Syntax highlighting was generating additional whitespace - fixed.
-- Added ucwords.  Works like ucfirst, but works on all words within a string.
-- Added array_walk() - apply user function to every element of an array
-- Added usort() - array sort that accepts a user defined comparison function!
-- Added the ability to call user-level functions and object methods on demand
-  from the C source using a completely generalized, slick API function.
-  Miracles do happen every once in a while.
-- Added constructors.  Don't even squeek about destructors! :) (we mean that)
-- Make pg_lowrite() binary safe
-- Fixed mod_charset option in ./setup
-- Fixed rewinddir() and dir()::rewind() under Win32 (they didn't work before).
-- Add Win32 COM support!  By-name referencing is supported using the IDispatch
-  interface (automation).  Available functions - COM_Load(), COM_Invoke(),
-  COM_PropGet() and COM_PropSet().
-  
-July 20 1998 Version 3.0.2a
-- Fix a quirk in the configuration file parser, the endless fountain of joy
-  and fun.

-  used in conjunction with error_reporting()
-  (e.g. error_reporting(E_ERROR|E_WARNING|E_NOTICE);
-- Fixed a crash problem with classes that contained function(s) with default
-  values.
-- Fixed a problem in the browscap module.  Browscap files weren't being read
-  properly.
-- Fix -L path in libphp4.module to make ApacheSSL compile without errors
-- Fix StripSlashes so it correctly decodes a \0 to a NUL
-

-- Implemented shift left and shift right operators (<< and >>)
-- Compile fix for cc on HP-UX.
-- Look for beta-version Solid libraries as well.
-- Make GD module show more info in phpinfo().
-- Compile fix for NextStep 3.0.
-- Fix for Oracle extension on OSF/1.
-- Fix gd 1.3 bug in ImageColorAt().
-- pg_loread() hopefully handles binary data now.
-- Turned off some warnings in dns.c
-- Added ImageTTFBBox() and made ImageTTFText() return bounding box.
-- Added constants for Ora_Bind()'s modes.
-- Renamed all hash_*() routines to _php3_hash_*() to avoid clashes with other
-  libraries.
-- Changed uodbc default LONG behaviour: longreadlen 4096 bytes, binmode 1.
-  The module now actually uses the php.ini settings.
-- New PostgreSQL functions:  pg_fetch_row(), pg_fetch_array()
-  and pg_fetch_object()
-- Fix a segmentation fault when calling invalid functions in certain
-  circumstances
-- Fix bug that caused link-related functions to not pay attention to
-  run-time safe mode setting (it was using whatever was set at compile time).

-
-June 6 1998 Version 3.0
-- Add checkdnsrr function (check availability DNS records)
-- Add getmxrr function (get MX hostnames and weights)
-- Fixed bug in nl2br() function
-- Fix for an RC5 related problem in the Sybase module, when dealing
-  with very long data types.
-- Speed up string concatenation by roughly a factor of 2
-- Add escape-handling to date function
-- Make base64 functions binary safe
-- Add strrpos function to complement strpos function added in RC5
-- Add ltrim function (strips only at the start of string)
-- Add rtrim as an alias to chop() for completeness sake
-- Add trim function (similar to chop, except it strips at the start as well)
-- Added 2 optional args to fsockopen function - errno and errstr
-- Fixed bug in split() function related to leading matches
-- Fixed problem in error_log() function (thanks to Jan Legenhausen)
-- empty("0") was returning true - fixed
-- Removed the old sybsql module.  Use the new sybase_*() functions instead.
-- Several fixes to the configuration file parser
-- LDAP fixes - fixed return values on several functions
-
-May 23 1998 Version 3.0RC5
-- The BC math library functions now compile in by default.
-- Fixed a bug in virtual() and other types of SSI's (e.g. <!--#exec).  Under
-  certain circumstances, this used to result in random problems.
-- Fixed a bug in virtual().  It was misbehaving if it was called before any
-  other output.
-- Added mysql.default_port, mysql.default_host, mysql.default_user and
-  mysql.default_password ini-file directives.
-- Improved handling of the MySQL default port.  It now honors /etc/services
-  and $MYSQL_TCP_PORT.
-- Fixed a crash in opening of broken ftp:// URLs, and improved error reporting
-  in opening of URLs.
-- Fixed several non-critical scanner issues with syntax highlighting mode and
-  the <script language=php> tag.
-- Fixed fseek on windows.  (windows only): fseek will not return proper results
-  on files opened as text mode.  PHP uses binary mode as the default for file
-  operations, but this can be overiden by fopen.  Do not open files in text
-  mode and use fseek on them!
-- Add strpos() function
-- Added zlib module, requires zlib >= 1.0.9
-- Improved the module API implementation.  Dynamic modules may now register
-  persistent resources (not that it makes much sense, but at least PHP
-  won't crash).  The API itself remains unchanged.
-- bcmod() wasn't always behaving like modulus should behave (it was behaving
-  exactly like GNU bc's % operator).  Fixed.
-- Changed the Sybase-DB module to always return strings, instead of auto-typing
-  result sets.  This was done for consistency with the other database modules,
-  and in order to avoid overflows due to the platform-dependant limitations
-  of the numeric data types of PHP.  You can turn compatability mode on using
-  the sybase.compatability_mode directive in the php3.ini file.
-- Fixed problems with the TINYINT field in the Sybase-CT module.
-- Applied some small speed optimizations to the Sybase-DB module querying code.
-- Added 'numeric' and 'type' properties to the object returned by
-  sybase_fetch_field().
-- The 'new' operator doesn't accept all expressions anymore.  Instead, it
-  accepts a class name, or a variable reference (scalar, array element, etc).
-- Add ora_numcols() function
-- Add ora_do() and ora_fetch_into() functions to Oracle driver
-- Add persistent connection support to Oracle driver
-- Make Oracle driver clean up open connections and open cursors automatically
-- Added fread() and fwrite() that properly handle binary data.
-- Add Ora_ColumnSize() to Oracle code
-- The string "0" means FALSE again.  This was done in order to maintain type
-  conversion consistency.
-- Added solid_fetch_prev() for fetching the previous result row from Solid.
-- Huge integers are now automatically converted to floating point numbers
-  (that have a wider range).
-- Floating point numbers are now displayed using scientific notation when
-  they're extremely big or extremely small.  The 'precision' php3.ini directive
-  no longer designates the number of decimal digits, but rather, the maximum
-  number of significant digits required.
-- Added support for scientific notation for floating point numbers (e.g. 1E7)
-  throughout the entire language.
-- Fixed a potential/probable memory corruption problem with HEAD request
-  handling.
-- Using un-encapsulated strings now generates a NOTICE-level warning
-  (e.g. $a = foo; instead of $a = "foo";)
-- Added defined("name") function to check if a certain constant is defined
-  or not.
-- Support new Apache mechanism for setting SERVER_SUBVERSION
-- Added PHP_OS and PHP_VERSION constants
-- Added the ability to define constants in runtime!  Constants are script-wide,
-  (there's no scope, once the constant is defined, it's valid everywhere).
-  Syntax is define("name", $value [, $case_insensitive]).  'name' can be any name
-  that is a valid variable name, *without* the $ prefix.  'value' can be
-  any *scalar* value.  If the optional 'case_insensitive' parameter is 1,
-  then the constant is created case-insensitive (the default is case
-  sensitive).  Note:  define() is currently *NOT* supported in preprocessed
-  scripts.
-- Added general support for constants.  The Syslog constants (e.g.
-  LOG_ERR, LOG_CRIT, etc.) should be accessed as constants from now on (that
-  is, without a $ prefix).  You can still set define_syslog_variables to On
-  in the php3.ini file if you want to define the various $ variables.  The
-  default for this directive in the php3.ini-dist file has been changed to
-  Off.
-- The configuration file path variable now expands . and .. into their
-  respective directories.  You can obtain the path of the php3.ini file
-  that was used by printing get_cfg_var("cfg_file_path").
-- Fixed a crash-recovery parser crash ($a=7; $a[3]+=5;)
-- Add gmmktime() function
-- Fixed a crash with implode() and empty arrays.
-- Fixed a bug that, under fairly rare circumstances, caused PHP not to
-  recognize if(), require() and other statements as statements, and
-  to complain about them as being unsupported functions.
-- Beautified php3.ini-dist and added more comments to it.  Also changed
-  the behavior of the configuration file parser to be brighter about
-  the various constants (TRUE/FALSE/ON/OFF etc).
-- Fixed a bug in openlog() - the specified device name was being mangled.
-- Memory leaks were sometimes reported erroneously - fixed.
-- Improved the convertor to handle some quirks of the PHP/FI 2 parser with
-  comments.
-- Fixed number_format() to properly handle negative numbers, and optimized it
-  a bit.
-- Fixed static variables inside class member functions.  Note that using such
-  static variables inside member functions usually defeats the purpose of
-  objects, so it is not recommended.
-- Fixed a bug in fpassthru() (the file was being closed twice).
-- Added strftime().
-- Add set_socket_blocking() function to control blocking on socket fd's
-- The sendmail_path in php3.ini was being ignored - fixed.
-- Fixed a bug with file upload, with files that contained the MIME boundary
-  inside them.
-- Fixed a bug with form variables of type array, with spaces in their
-  index (e.g. name="foo[bar bar]").
-- gd-1.3 autodetect and support
-- Year 2000 compliance is now togglable from the php3.ini file.  Setting PHP
-  to be y2k compliant effects the way it creates cookies, and means it'll
-  NOT work with many browsers out there that are not y2k compliant!  For
-  that reason, the default for this option is off.
-- safe mode / fix from monti@vesatec.com
-- Integrated the FreeType support in the GD extension.
-- Added --with-gd=DIR and --without-gd options to configure
-
-April 18 1998 Version 3.0 Release Candidate 4
-- Auto-prepended and auto-appended files were reporting the wrong filename
-  in errors and in __FILE__ - fixed.
-- Fix GPC problem related to mixed scalar and array vars with the same name
-- Made putenv() Apache-safe.  Environment variables may no longer leak in
-  between requests.
-- The trailing semicolon is no longer required in class declarations.
-- Fixed a memory leak in the (array) and (object) operators under certain
-  conditions.
-- <script> tags weren't working unless short tags were enabled - Fixed.
-- Fixed a bug in certain array indices that weren't treated as numbers
-  even though they looked like numbers (e.g. "10", "20").
-- Changes to support renamed API functions in Apache-1.3
-- Fixed the -p and -e command line switches
-- Fix a segfault when calling command line version without parameters
-- Fix for feof() when used on a socket
-- Fix off-by-one error in fgets() when used on a socket
-- Fix bug in ImageSetPixel() (Thanks to ecain@Phosphor.net)
-
-March 31 1998 Version 3.0 Release Candidate 3
-- Tiny bugfix for magic_quotes_sybase
-- Fix Apache build problems introduced in RC2
-- $a["0"]==$a[0] fix
-- Apache-1.3 build changes to support 100% automatic builds and shared library
-  module builds.  See INSTALL file.
- 
-March 30 1998 Version 3.0 Release Candidate 2
-- Changed the socket implementation under UNIX to not use FILE pointers, in
-  order to work around the buggy Solaris libc (and possibly buggy libc's
-  in other platforms).
-- Fixed a bug in min() and max() with certain arrays.
-- *WARNING* Move Apache 1.3 php3 file install to src/modules/php4 instead of 
-  src/modules/extra.  Make sure you change your AddModule line correctly
-  in your Apache Configuration file.  This change is to take advantage of 
-  new Apache-1.3 configuration mechanism which makes it easier to build an
-  Apache server with PHP automatically enabled.  It will also help building
-  a shared library module version of PHP soon.
-- Fixed a crash bug with auto-appended files.
-- Made --enable-discard-path work on all Unix servers #!/path/php CGI scripts 
-  should now work everywhere.  I have tested on Apache, WN and Netscape 2.0
-- Made $a["123"] and $a[123] be identical.  $a["0123"] is still different,
-  though.
-- Added 'precision' ini directive, to set the number of decimal digits
-  displayed for floating point numbers (default - 6).
-- Made integer/integer divisions evaluate to floating point numbers when
-  applicable (e.g., 5/2==2.5(float), but 4/2==2(int))
-- Get rid of reliance on tied streams and move all socket reads and writes
-  to recv/send calls
-- Cleaned up head.c a bit and fixed CGI SetCookie order problem
-- Changed default variable parsing order to Get-Cookie-Post (GPC)
-- Fixed setup so it has all configure options and defaults.
-- Added optional decimal point and thousands seperator to number_format()
-  e.g., number_format(1500,2,',','.') == 1.500,00
-- Fixed cgi bug in windows that prevented files from being parsed on many
-  systems and servers.
-
-March 23 1998 Version 3.0 Release Candidate
-- Added support for the Raima database (ALPHA)
-- Fixed a bug in persistent PostgreSQL links and the connection-string method.
-- Added EXTENSION_STATUS file, that specifies the stability and status of
-  every module in the distribution.
-- Added optional parameters to user functions with default values, variables
-  that are forced to be passed by reference and variables that can be
-  optionally passed by reference.  The ini file directive
-  'ignore_missing_userfunc_args' is no longer supported.
-- Added fhttpd support (by Alex Belits)
-- Improved performance by approximately 20-30%.
-- Added mysql_error(), mysql_errno() (if available) and msql_error().
-  Errors coming back from the database backend no longer issue warnings.
-  Instead, use these functions to retreive the error.
-- Patched count(), each(), prev(), next(), reset() and end() to work around
-  the implementation side effects of unset().  As far as the users are
-  concerned, this should be transparent now (even though it's slower now,
-  until it's thoroughly fixed in 3.1).
-- Added number_format().  number_format(2499,2)=='2,499.00'.
-- error_reporting() now sets the error reporting level to the supplied
-  argument, without any interpretations.
-- Fixed a lookahead parser bug that occured under rare circumstances.
-- Change the comparison operators to compare numeric strings as numbers.  If
-  you want to compare them as strings, you can use the new C-like strcmp()
-- Fixed Ora_GetColumn() bug when fetching strings
-- Added Ora_ColumnName() and Ora_ColumnType()
-- Preliminary LONG and LONG RAW support in Oracle extension
-- Add \123 and \xAB style octal and hex escapes to "" and `` strings
-- Add "-c" command line flag for specifying path to php3.ini file
-- Improved list() so that elements can be skipped, for example:
-  list($name,,,$realname) = explode(":",fgets($passwd_file));
-- Fixed a tiny bug in the hash initialization which caused excessive use of
-  memory. Report and fix by short@k332.feld.cvut.cz
-- Fixed strtolower() and strtoupper() to work with 8-bit chars

-  script termination (e.g. eval("exit();").
-- Fixed a syntax highlighting problem with keywords used as variable
-  names.
-- Fixed a possible crash and/or file descriptor leak
-- Fixed line number being off by one in #! shell style execution
-- Made it possible to disable auto_prepend/append with "none" filename
-- Allow safe CGI calling through #!php style scripts
-

-  which are refered to as objects.
-- Fixed several fields that were being incorrectly read in Sybase CT.
-- Fix Apache-1.3 related SIGHUP problem which was preventing php3.ini from 
-  getting re-read on a SIGHUP
-- *** WARNING *** Downwards incompatible change:  The plus operator (+) is not
-  longer overloaded as concatenation for strings.  Instead, it converts its
-  arguments to numbers and performs numeric addition.

-- Walked around an implementation side effect of switch().  <? switch(expr) { ?>
-  now works.
-- Added memory caching, resulting in a significant performance boost
-- Added support for for(): .. endfor; loops
-- Added a new predicate - empty($var).  Returns true if $var is not set,
-  or is FALSE.  Returns false otherwise.
-- Added is_integer() (same as is_long()) and is_real() (same as is_double()).
-- Added sizeof() as an alias to the count() function
-- Added --enable-force-cgi-redirect, to prevent the CGI from working if
-  someone directly accesses PHP not through Apache's CGI redirect
-  (off by default).
-- Fixed marking of deleted dBase records. Noticed by Simon Gornall
-  <simon@oyster.co.uk>.

-- Added highlight_string() - behaves like highlight_file(), only instead
-  of highlighting a file, it syntax highlights the contents of its
-  argument.
-- Renamed show_source() to highlight_file().  show_source() is still
-  supported for downwards compatability.
-- Fixed a bug in class inheritence - member functions with upper case
-  letters in their names couldn't be redefined.

-  octal and hex numbers recognized.
-- Fixed a possible segfault bug in several functions, when using the concat
-  operator and possibly other operators/functions.

-  under Windows.
-- Fixed ereg_replace replacing empty matches and a one off buffer overflow
-- Fixed File upload on windows platform
-- Fixed a bug that caused 'HTTP/1.1 100 Continue' messages with 
-  Internet Explorer 4.0 and certain scripts that receive POST variables
-- Get/POST/Cookie data variables are from now *ALWAYS* strings.  If you want
-  to use them in integer/real context, you must explicitly change their types.

-- Made the regexp function automatically take arguments by reference
-  when necessary
-- Added builtin support for auto append and prepend in the parser level
-- Improved the Sybase/CT sybase_query().  Should be more stable now, and
-  hopefully work with a wider range of queries.  It's difficult to work
-  without docs, though, so it may still not be 100% right...
-- Changed error messages to show error type, file and line with bold
-- Added support for autoprepend and autoprepend
-- Added some more warning flags if gcc is used
-
-December 03 1997 Version 3.0a4
-- Improved the internal functions API - no need to explicitly pass
-  parameters by reference to internal functions that specifically
-  require them, e.g. sort(), ksort(), reset(), count(), etc.
