1 Version 3.07
2 1. Fixed typo in mod_perl detection.
3
4 Version 3.06
5
6 1. Fixed bare call to script() in start_html
7 2. Moved Fh::DESTROY out of autoloaded functions so as to avoid
8 clobbering $@ when CGI functions are executed in an eval{}
9 context.
10 3. mod_perl 2.0 version detection patch in CGI::Cookie provided by
11 Allen Day.
12 4. autoEscape() flag is now respected when generating extra
13 attributes.
14 5. Tests for *tag start/end generation from Shlomi Fish.
15 6. Support for can() method provided by Ron Savage.
16 7. Fix for lang='' when outputting XHTML.
17 8. Added support for chunked transfer encoding, as suggested by
18 Hakan Ardo
19 9. Fixed clobbering of row and column headers in tableized radio
20 and checkbox groups, as reported by Nicolas Thierry-Mieg.
21 10. <Label> tags are now associated with form elements, as suggested
22 by accessibility guidelines.
23 11. The <?xml> directive produced by start_html is now turned off by
24 default and the charset is specified in a <meta> directive. Apparently
25 IE6 (and maybe some versions of Opera) were getting confused by this.
26 12. Support for tab indexes.
27 13. Retired the HTML docs. The POD docs are now primary documentation.
28 14. CGI::Carp now correctly detects and handles Apache::Dispatch.
29 15. CGI::Util::utf8_chr now correctly sets the UTF8 flag on 5.006 or
30 higher perls (fix courtesy Slaven Rezic).
31
32
33 Version 3.05
34
35 1. Fixed uninitialized variable warning on start_form() when running
36 from command line.
37 2. Fixed CGI::_set_attributes so that attributes with a - are handled
38 correctly.
39 3. Fixed CGI::Carp::die() so as to avoid problems from _longmess()
40 clobbering @_.
41 4. If HTTP_X_FORWARDED_HOST is defined (i.e. running under a proxy),
42 the various functions that return HOST will use that instead.
43 5. Fix for undefined utf8() call in CGI::Util.
44 6. Changed the call to warningsToBrowser() in
45 CGI::Carp::fatalsToBrowser to call only after HTTP header is sent
46 (thanks to Didier Lebrun for noticing).
47 7. Patches from Dan Harkless to make CGI.pm validatable against HTML
48 3.2.

58 13. During server push, set NPH to 0 rather than 1. This is supposed
59 to fix problems with Apache.
60 14. Fixed incorrect processing of multipart form fields that contain
61 embedded quotes. There's still the issue of how to handle ones
62 that contain embedded semicolons, but no one has complained (yet).
63 15. Fixed documentation bug in -style argument to start_html()
64 16. Added -status argument to redirect().

568 CGI->image_button(), to fail.
569 4. Fixed bug which caused strong('CGI') to fail. Be careful to use
570 CGI::strong('CGI') and not CGI->strong('CGI'). The latter will
571 produce confusing results.
572 5. Added upload() function, as a preferred replacement for the
573 "filehandle as string" feature.
574 6. Added cgi_error() function.
575 7. Rewrote file upload handling to return undef rather than dieing
576 when an error is encountered. Be sure to call cgi_error() to find
577 out what went wrong.
578
579 Version 2.46
580
581 1. Fix for failure of the "include" tests under mod_perl
582 2. Added end_multipart_form to prevent failures during qw(-compile
583 :all)
584
585 Version 2.45
586
587 1. Multiple small documentation fixes
588 2. CGI::Pretty didn't get into 2.44. Fixed now.
589
590 Version 2.44
591
592 1. Fixed file descriptor leak in upload function.
593 2. Fixed bug in header() that prevented fields from containing double
594 quotes.
595 3. Added Brian Paulsen's CGI::Pretty package for pretty-printing
596 output HTML.
597 4. Removed CGI::Apache and CGI::Switch from the distribution.
598 5. Generated start_* shortcuts so that start_table(), end_table(),
599 start_ol(), end_ol(), and so forth now work (see the docs on how
600 to enable this feature).
601 6. Changed accept() to Accept(), sub() to Sub(). There's still a
602 conflict with reset(), but this will break too many existing
603 scripts!
604
605 Version 2.43
606
607 1. Fixed problem with "use strict" and file uploads (thanks to Peter
608 Haworth)
609 2. Fixed problem with not MSIE 3.01 for the power_mac not doing file
610 uploads right.
611 3. Fixed problem with file upload on IIS 4.0 when authorization in
612 use.
613 4. -content_type and '-content-type' can now be provided to header()
614 as synonyms for -type.
615 5. CGI::Carp now escapes the ampersand BEFORE escaping the > and <
616 signs.
617 6. Fixed "not an array reference" error when passing a hash reference
618 to radio_group().
619 7. Fixed non-removal of uploaded TMP files on NT platforms which
620 occurs when server runs on non-C drive (thanks to Steve Kilbane
621 for finding this one).
622
623 Version 2.42
624
625 1. Too many screams of anguish at changed behavior of url(). Is now
626 back to its old behavior by default, with options to generate all
627 the variants.
628 2. Added regression tests. "make test" now works.
629 3. Documentation fixes.
630 4. Fixes for Macintosh uploads, but uploads STILL do not work pending
631 changes to MacPerl.
632
633 Version 2.41
634
635 1. url() method now includes the path info. Use script_name() to get
636 it without path info().
637 2. Changed handling of empty attributes in HTML tag generation. Be
638 warned! Use table({-border=>undef}) rather than
639 table({-border=>''}).
640 3. Changes to allow uploaded filenames to be compared to other
641 strings with "eq", "cmp" and "ne".
642 4. Changes to allow CGI.pm to coexist more peacefully with
643 ActiveState PerlEX.
644 5. Changes to prevent exported variables from clashing when importing
645 ":all" set in combination with cookies.
646
647 Version 2.40
648
649 1. CGI::Carp patched to work better with mod_perl (thanks to Chris
650 Dean).
651 2. Uploads of files whose names begin with numbers or the Windows
652 \\UNC\shared\file nomenclature should no longer fail.
653 3. The <STYLE> tag (for cascading style sheets) now generates the
654 required TYPE attribute.
655 4. Server push primitives added, thanks to Ed Jordan.
656 5. Table and other HTML3 functions are now part of the :standard set.
657 6. Small documentation fixes.
658
659 TO DO:
660 1. Do something about the DTD mess. The module should generate
661 correct DTDs, or at least offer the programmer a way to specify
662 the correct one.
663 2. Split CGI.pm into CGI processing and HTML-generating modules.
664 3. More robust file upload (?still not working on the Macintosh?).
665 4. Bring in all the HTML4 functionality, particular the accessibility
666 features.
667
668 Version 2.39
669
670 1. file uploads failing because of VMS patch; fixed.
671 2. -dtd parameter was not being properly processed.
672
673 Version 2.38
674
675 I finally got tired of all the 2.37 betas and released 2.38. The main
676 difference between this version and the last 2.37 beta (2.37b30) are
677 some fixes for VMS. This should allow file upload to work properly on
678 all VMS Web servers.
679
680 Version 2.37, various beta versions
681
682 1. Added a CGI::Cookie::parse() method for lucky mod_perl users.
683 2. No longer need separate -values and -labels arguments for
684 multi-valued form elements.

691 importing.
692 7. Documented the import pragmas a little better.
693 8. Added a -compile switch to the use clause for the long-suffering
694 mod_perl and Perl compiler users.

696 work correctly (and hash initialization doesn't fail!).
697 10. Better deletion of temporary files on NT systems.
698 11. Added documentation on escape(), unescape(), unescapeHTML() and
699 unescapeHTML() subroutines.
700 12. Added documentation on creating subclasses.

710 20. Fixed vanishing cookie problem.
711 21. Fixed warning in initialize_globals() under mod_perl.
712 22. File uploads from Macintosh versions of MSIE should now work.
713 23. Pragmas now preceded by dashes (-nph) rather than colons (:nph).
714 Old style is supported for backward compatability.
715 24. Can now pass arguments to all functions using {} brackets,
716 resolving historical inconsistencies.
717 25. Removed autoloader warnings about absent MultipartBuffer::DESTROY.
718 26. Fixed non-sticky checkbox() when -name used without -value.
719 27. Hack to fix path_info() in IIS 2.0. Doesn't help with IIS 3.0.
720 28. Parameter syntax for debugging from command line now more
721 straightforward.
722 29. Added $DISABLE_UPLOAD to disable file uploads.
723 30. Added $POST_MAX to error out if POSTings exceed some ceiling.
724 31. Fixed url_param(), which wasn't working at all.
725 32. Fixed variable suicide problem in s///e expressions, where the
726 autoloader was needed during evaluation.
727 33. Removed excess spaces between elements of checkbox and radio
728 groups
729 34. Can now create "valueless" submit buttons
730 35. Can now set path_info as well as read it.
731 36. ReadParse() now returns a useful function result.
732 37. import_names() now allows you to optionally clear out the
733 namespace before importing (for mod_perl users)
734 38. Made it possible to have a popup menu or radio button with a value
735 of "0".
736 39. link() changed to Link() to avoid overriding native link function.
737 40. Takes advantage of mod_perl's register_cleanup() function to clear
738 globals.
739 41. <LAYER> and <ILAYER> added to :html3 functions.
740 42. Fixed problems with private tempfiles and NT/IIS systems.
741 43. No longer prints the DTD by default (I bet no one will complain).
742 44. Allow underscores to replace internal hyphens in parameter names.
743 45. CGI::Push supports heterogeneous MIME types and adjustable delays
744 between pages.
745 46. url_param() method added for retrieving URL parameters even when a
746 fill-out form is POSTed.
747 47. Got rid of warnings when radio_group() is called.
748 48. Cookies now moved to their very own module.
749 49. Fixed documentation bug in CGI::Fast.
750 50. Added a :no_debug pragma to the import list.
751
752 Version 2.36
753
754 1. Expanded JavaScript functionality
755 2. Preliminary support for cascading stylesheets
756 3. Security fixes for file uploads:
757 + Module will bail out if its temporary file already exists
758 + Temporary files can now be made completely private to avoid
759 peeking by other users or CGI scripts.
760 4. use CGI qw/:nph/ wasn't working correctly. Now it is.
761 5. Cookie and HTTP date formats didn't meet spec. Thanks to Mark
762 Fisher (fisherm@indy.tce.com) for catching and fixing this.
763
764 p
765
766 Version 2.35
767
768 1. Robustified multipart file upload against incorrect syntax in
769 POST.
770 2. Fixed more problems with mod_perl.
771 3. Added -noScript parameter to start_html().
772 4. Documentation fixes.
773
774 Version 2.34
775
776 1. Stupid typo fix
777
778 Version 2.33

786
787 1. Improved support for Apache's mod_perl.
788 2. Changes to better support inheritance.
789 3. Support for OS/2.
790
791 Version 2.31
792
793 1. New uploadInfo() method to obtain header information from uploaded
794 files.
795 2. cookie() without any arguments returns all the cookies passed to a
796 script.
797 3. Removed annoying warnings about $ENV{NPH} when running with the -w
798 switch.
799 4. Removed operator overloading throughout to make compatible with
800 new versions of perl.
801 5. -expires now implies the -date header, to avoid clock skew.
802 6. WebSite passes cookies in $ENV{COOKIE} rather than
803 $ENV{HTTP_COOKIE}. We now handle this, even though it's O'Reilly's
804 fault.
805 7. Tested successfully against new sfio I/O layer.
806 8. Documentation fixes.
807
808 Version 2.30
809
810 1. Automatic detection of operating system at load time.
811 2. Changed select() function to Select() in order to avoid conflict
812 with Perl built-in.
813 3. Added Tr() as an alternative to TR(); some people think it looks
814 better that way.
815 4. Fixed problem with autoloading of MultipartBuffer::DESTROY code.
816 5. Added the following methods:
817 + virtual_host()
818 + server_software()
819 6. Automatic NPH mode when running under Microsoft IIS server.
820
821 Version 2.29
822
823 1. Fixed cookie bugs
824 2. Fixed problems that cropped up when useNamedParameters was set to
825 1.
826 3. Prevent CGI::Carp::fatalsToBrowser() from crapping out when
827 encountering a die() within an eval().
828 4. Fixed problems with filehandle initializers.
829
830 Version 2.28
831
832 1. Added support for NPH scripts; also fixes problems with Microsoft
833 IIS.
834 2. Fixed a problem with checkbox() values not being correctly saved
835 and restored.
836 3. Fixed a bug in which CGI objects created with empty string
837 initializers took on default values from earlier CGI objects.
838 4. Documentation fixes.
839
840 Version 2.27
841
842 1. Small but important bug fix: the automatic capitalization of tag
843 attributes was accidentally capitalizing the VALUES as well as the
844 ATTRIBUTE names (oops).
845
846 Version 2.26
847
848 1. Changed behavior of scrolling_list(), checkbox() and
849 checkbox_group() methods so that defaults are honored correctly.
850 The "fix" causes endform() to generate additional <INPUT
851 TYPE="HIDDEN"> tags -- don't be surpised.
852 2. Fixed bug involving the detection of the SSL protocol.
853 3. Fixed documentation error in position of the -meta argument in
854 start_html().
855 4. HTML shortcuts now generate tags in ALL UPPERCASE.
856 5. start_html() now generates correct SGML header:
857 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
858
859 6. CGI::Carp no longer fails "use strict refs" pragma.
860
861 Version 2.25
862
863 1. Fixed bug that caused bad redirection on destination URLs with
864 arguments.
865 2. Fixed bug involving use_named_parameters() followed by
866 start_multipart_form()
867 3. Fixed bug that caused incorrect determination of binmode for
868 Macintosh.
869 4. Spelling fixes on documentation.
870
871 Version 2.24
872
873 1. Fixed bug that caused generation of lousy HTML for some form
874 elements
875 2. Fixed uploading bug in Windows NT
876 3. Some code cleanup (not enough)
877
878 Version 2.23
879
880 1. Fixed an obscure bug that caused scripts to fail mysteriously.
881 2. Fixed auto-caching bug.
882 3. Fixed bug that prevented HTML shortcuts from passing taint checks.
883 4. Fixed some -w warning problems.
884
885 Version 2.22
886
887 1. New CGI::Fast module for use with FastCGI protocol. See pod
888 documentation for details.
889 2. Fixed problems with inheritance and autoloading.
890 3. Added TR() (<tr>) and PARAM() (<param>) methods to list of
891 exported HTML tag-generating functions.
892 4. Moved all CGI-related I/O to a bottleneck method so that this can
893 be overridden more easily in mod_perl (thanks to Doug MacEachern).
894 5. put() method as substitute for print() for use in mod_perl.
895 6. Fixed crash in tmpFileName() method.
896 7. Added tmpFileName(), startform() and endform() to export list.
897 8. Fixed problems with attributes in HTML shortcuts.
898 9. Functions that don't actually need access to the CGI object now no
899 longer generate a default one. May speed things up slightly.
900 10. Aesthetic improvements in generated HTML.
901 11. New examples.
902
903 Version 2.21
904
905 1. Added the -meta argument to start_html().
906 2. Fixed hidden fields (again).
907 3. Radio_group() and checkbox_group() now return an appropriate
908 scalar value when called in a scalar context, rather than
909 returning a numeric value!
910 4. Cleaned up the formatting of form elements to avoid unesthetic
911 extra spaces within the attributes.
912 5. HTML elements now correctly include the closing tag when
913 parameters are present but null: em('')
914 6. Added password_field() to the export list.
915
916 Version 2.20
917
918 1. Dumped the SelfLoader because of problems with running with taint
919 checks and rolled my own. Performance is now significantly
920 improved.
921 2. Added HTML shortcuts.
922 3. import() now adheres to the Perl module conventions, allowing
923 CGI.pm to import any or all method names into the user's name
924 space.
925 4. Added the ability to initialize CGI objects from strings and
926 associative arrays.
927 5. Made it possible to initialize CGI objects with filehandle
928 references rather than filehandle strings.
929 6. Added the delete_all() and append() methods.
930 7. CGI objects correctly initialize from filehandles on NT/95 systems
931 now.
932 8. Fixed the problem with binary file uploads on NT/95 systems.
933 9. Fixed bug in redirect().
934 10. Added '-Window-target' parameter to redirect().
935 11. Fixed import_names() so that parameter names containing funny
936 characters work.
937 12. Broke the unfortunate connection between cookie and CGI parameter
938 name space.
939 13. Fixed problems with hidden fields whose values are 0.
940 14. Cleaned up the documentation somewhat.
941
942 Version 2.19
943
944 1. Added cookie() support routines.
945 2. Added -expires parameter to header().
946 3. Added cgi-lib.pl compatability mode.
947 4. Made the module more configurable for different operating systems.
948 5. Fixed a dumb bug in JavaScript button() method.
949
950 Version 2.18
951
952 1. Fixed a bug that corrects a hang that occurs on some platforms
953 when processing file uploads. Unfortunately this disables the
954 check for bad Netscape uploads.
955 2. Fixed bizarre problem involving the inability to process uploaded
956 files that begin with a non alphabetic character in the file name.
957 3. Fixed a bug in the hidden fields involving the -override directive
958 being ignored when scalar defaults were passed.
959 4. Added documentation on how to disable the SelfLoader features.
960
961 Version 2.17
962
963 1. Added support for the SelfLoader module.
964 2. Added oodles of JavaScript support routines.
965 3. Fixed bad bug in query_string() method that caused some parameters
966 to be silently dropped.
967 4. Robustified file upload code to handle premature termination by
968 the client.
969 5. Exported temporary file names on file upload.
970 6. Removed spurious "uninitialized variable" warnings that appeared
971 when running under 5.002.
972 7. Added the Carp.pm library to the standard distribution.
973 8. Fixed a number of errors in this documentation, and probably added
974 a few more.
975 9. Checkbox_group() and radio_group() now return the buttons as
976 arrays, so that you can incorporate the individual buttons into
977 specialized tables.
978 10. Added the '-nolabels' option to checkbox_group() and
979 radio_group(). Probably should be added to all the other
980 HTML-generating routines.
981 11. Added the url() method to recover the URL without the entire query
982 string appended.
983 12. Added request_method() to list of environment variables available.
984 13. Would you believe it? Fixed hidden fields again!
985
986 Version 2.16
987
988 1. Fixed hidden fields yet again.
989 2. Fixed subtle problems in the file upload method that caused
990 intermittent failures (thanks to Keven Hendrick for this one).
991 3. Made file upload more robust in the face of bizarre behavior by
992 the Macintosh and Windows Netscape clients.
993 4. Moved the POD documentation to the bottom of the module at the
994 request of Stephen Dahmen.
995 5. Added the -xbase parameter to the start_html() method, also at the
996 request of Stephen Dahmen.
997 6. Added JavaScript form buttons at Stephen's request. I'm not sure
998 how to use this Netscape extension correctly, however, so for now
999 the form() method is in the module as an undocumented feature. Use
1000 at your own risk!
1001
1002 Version 2.15
1003
1004 1. Added the -override parameter to all field-generating methods.
1005 2. Documented the user_name() and remote_user() methods.
1006 3. Fixed bugs that prevented empty strings from being recognized as
1007 valid textfield contents.
1008 4. Documented the use of framesets and added a frameset example.
1009
1010 Version 2.14
1011
1012 This was an internal experimental version that was never released.
1013
1014 Version 2.13
1015
1016 1. Fixed a bug that interfered with the value "0" being entered into
1017 text fields.
1018
1019 Version 2.01
1020
1021 1. Added -rows and -columns to the radio and checkbox groups. No
1022 doubt this will cause much grief because it seems to promise a
1023 level of meta-organization that it doesn't actually provide.
1024 2. Fixed a bug in the redirect() method -- it was not truly HTTP/1.0
1025 compliant.
1026
1027 Version 2.0
1028
1029 The changes seemed to touch every line of code, so I decided to bump
1030 up the major version number.
1031 1. Support for named parameter style method calls. This turns out
1032 to be a big win for extending CGI.pm when Netscape adds new HTML
1033 "features".
1034 2. Changed behavior of hidden fields back to the correct "sticky"
1035 behavior. This is going to break some programs, but it is for
1036 the best in the long run.
1037 3. Netscape 2.0b2 broke the file upload feature. CGI.pm now handles
1038 both 2.0b1 and 2.0b2-style uploading. It will probably break again
1039 in 2.0b3.
1040 4. There were still problems with library being unable to distinguish
1041 between a form being loaded for the first time, and a subsequent
1042 loading with all fields blank. We now forcibly create a default
1043 name for the Submit button (if not provided) so that there's
1044 always at least one parameter.
1045 5. More workarounds to prevent annoying spurious warning messages
1046 when run under the -w switch. -w is seriously broken in perl
1047 5.001!
1048
1049 Version 1.57
1050
1051 1. Support for the Netscape 2.0 "File upload" field.
1052 2. The handling of defaults for selected items in scrolling lists and
1053 multiple checkboxes is now consistent.
1054
1055 Version 1.56
1056
1057 1. Created true "pod" documentation for the module.
1058 2. Cleaned up the code to avoid many of the spurious "use of
1059 uninitialized variable" warnings when running with the -w switch.
1060 3. Added the autoEscape() method. v
1061 4. Added string interpolation of the CGI object.
1062 5. Added the ability to pass additional parameters to the <BODY> tag.
1063 6. Added the ability to specify the status code in the HTTP header.
1064
1065 Bug fixes in version 1.55
1066
1067 1. Every time self_url() was called, the parameter list would grow.
1068 This was a bad "feature".
1069 2. Documented the fact that you can pass "-" to radio_group() in
1070 order to prevent any button from being highlighted by default.
1071
1072 Bug fixes in version 1.54
1073
1074 1. The user_agent() method is now documented;
1075 2. A potential security hole in import() is now plugged.
1076 3. Changed name of import() to import_names() for compatability with
1077 CGI:: modules.
1078
1079 Bug fixes in version 1.53
1080
1081 1. Fixed several typos in the code that were causing the following
1082 subroutines to fail in some circumstances
1083 1. checkbox()
1084 2. hidden()
1085 2. No features added
1086
1087 New features added in version 1.52
1088
1089 1. Added backslashing, quotation marks, and other shell-style escape
1090 sequences to the parameters passed in during debugging off-line.
1091 2. Changed the way that the hidden() method works so that the default
1092 value always overrides the current one.
1093 3. Improved the handling of sticky values in forms. It's now less
1094 likely that sticky values will get stuck.
1095 4. If you call server_name(), script_name() and several other methods
1096 when running offline, the methods now create "dummy" values to
1097 work with.
1098
1099 Bugs fixed in version 1.51
1100
1101 1. param() when called without arguments was returning an array of
1102 length 1 even when there were no parameters to be had. Bad bug!
1103 Bad!
1104 2. The HTML code generated would break if input fields contained the
1105 forbidden characters ">< or &. You can now use these characters
1106 freely.
1107
1108 New features added in version 1.50
1109
1110 1. import() method allows all the parameters to be imported into a
1111 namespace in one fell swoop.
1112 2. Parameters are now returned in the same order in which they were
1113 defined.
1114
1115 Bugs fixed in version 1.45
1116
1117 1. delete() method didn't work correctly. This is now fixed.
1118 2. reset() method didn't allow you to set the name of the button.
1119 Fixed.
1120
1121 Bugs fixed in version 1.44
1122
1123 1. self_url() didn't include the path information. This is now fixed.
1124
1125 New features added in version 1.43
1126
1127 1. Added the delete() method.
1128
1129 New features added in version 1.42
1130
1131 1. The image_button() method to create clickable images.
1132 2. A few bug fixes involving forms embedded in <PRE> blocks.
1133
1134 New features added in version 1.4
1135
1136 1. New header shortcut methods
1137 + redirect() to create HTTP redirection messages.
1138 + start_html() to create the HTML title, complete with the
1139 recommended <LINK> tag that no one ever remembers to include.
1140 + end_html() for completeness' sake.
1141 2. A new save() method that allows you to write out the state of an
1142 script to a file or pipe.
1143 3. An improved version of the new() method that allows you to restore
1144 the state of a script from a file or pipe. With (2) this gives you
1145 dump and restore capabilities! (Wow, you can put a "121,931
1146 customers served" banner at the bottom of your pages!)
1147 4. A self_url() method that allows you to create state-maintaining
1148 hypertext links. In addition to allowing you to maintain the state
1149 of your scripts between invocations, this lets you work around a
1150 problem that some browsers have when jumping to internal links in
1151 a document that contains a form -- the form information gets lost.
1152 5. The user-visible labels in checkboxes, radio buttons, popup menus
1153 and scrolling lists have now been decoupled from the values sent
1154 to your CGI script. Your script can know a checkbox by the name of
1155 "cb1" while the user knows it by a more descriptive name. I've
1156 also added some parameters that were missing from the text fields,
1157 such as MAXLENGTH.
1158 6. A whole bunch of methods have been added to get at environment
1159 variables involved in user verification and other obscure
1160 features.
1161
1162 Bug fixes
1163
1164 1. The problems with the hidden fields have (I hope at last) been
1165 fixed.
1166 2. You can create multiple query objects and they will all be
1167 initialized correctly. This simplifies the creation of multiple
1168 forms on one page.
1169 3. The URL unescaping code works correctly now.
