- make perldoc CGI object consistent (GH #205)
- clarify reason for absolute URLs (GH #206)
- tweak dependency defs in Makefile.PL (GH #207, GH #208)
- (thanks to karenetheridge and kentfredric)
4.31 2016-06-14
- Add SameSite support to Cookie handling (thanks to pangyre)
- The MultipartBuffer package has been renamed to CGI::MultipartBuffer.
This has been done in a way to ensure any $MultipartBuffer package
variables are still set correctly in CGI::MultipartBuffer. if you are
explicitly using MultipartBuffer in a form such as:
your code will break. you should be calling:
CGI->new->new_MultipartBuffer( $boundary,$length );
to ensure the correctly package is called. if you are extending the
MultipartBuffer package though use of ISA or base (or parent) then you
will need to update your code to use CGI::MultipartBuffer

4.21 2015-06-16
- is now considered "done". See also "mature" and "legacy"
Features requests and non-critical issues will be outright rejected.
The module is now in maintenance mode for critical issues only.
- This release removes the AUTOLOAD and compile optimisations from
that were introduced into twenty (20) years ago as a response to
its large size, which meant there was a significant compile time penalty.
- This optimisation is no longer relevant and makes the code difficult to
deal with as well as making test coverage metrics incorrect. Benchmarks
show that advantages of AUTOLOAD / lazy loading / deferred compile are
less than 0.05s, which will be dwarfed by just about any meaningful code
in a cgi script. If this is an issue for you then you should look at
running in a persistent environment (FCGI, etc)
- To offset some of the time added by removing the AUTOLOAD functionality
the dependencies have been made runtime rather than compile time. The
POD has also been split into its own file. now contains around
4000 lines of code, which compared to some modules on CPAN isn't really
that much
- This essentially deprecates the -compile pragma and ->compile method. The
-compile pragma will no longer do anything, whereas the ->compile method
will raise a deprecation warning. More importantly this also REMOVES the
-any pragma because as per the documentation this pragma needed to be
"used with care or not at all" and allowing arbitrary HTML tags is almost
certainly a bad idea. If you are using the -any pragma and using arbitrary
tags (or have typo's in your code) your code will *BREAK*
- Although this release should be back compatible (with the exception of any
code using the -any pragma) you are encouraged to test it throughly as if
you are doing anything out of the ordinary with (i.e. have bugs
that may have been masked by the AUTOLOAD feature) you may see some issues.
- References: GH #162, GH #137, GH #164
- make the list context warning in param show the filename rather than
the package so we have more information on exactly where the warning
has been raised from (GH #171)
- correct self_url when PATH_INFO and SCRIPT_NAME are the same but we
are not running under IIS (GH #176)
- Add the multi_param method to :cgi export (thanks to xblitz for the patch
and tests. GH #167)
- Fix warning for lack of HTTP_USER_AGENT in CGI::Carp (GH #168)
- Fix imports when called from CGI::Fast, restores the import of CGI functions
into the callers namespace for users of CGI::Fast (GH leejo/cgi-fast#11 and
GH leejo/cgi-fast#12)
- Fix regression of tmpFileName when calling with a plain string (GH #178,
thanks to Simon McVittie for the report and fix)
- CGI::Carp now has $CGI::Carp::FULL_PATH for displaying the full path to the
offending script in error messages
- CGI now has env_query_string() for getting the value of QUERY_STRING from
the environment and not that fiddled with by (which is what
query_string() does) (GH #161)
- CGI::ENCODE_ENTITIES var added to control which chracters are encoded by
the call to the HTML::Entities module - defaults to &<>"' (GH #157 - the
\x8b and \x9b chars have been removed from this list as we are concerned
more about unicode compat these days than old browser support.)
- Fix some typos (GH #173, GH #174)
- All *documentation* for HTML functionality in CGI has been moved into
its own namespace: CGI::HTML::Functions - although the functionality
continues to exist within so there are no code changes required
(GH #142)
- Add missing documentation for env variable fetching routines (GH #163)
- Increase test coverage (GH #3)
- Cwd made a TEST_REQUIRES rather than a BUILD_REQUIRES in Makefile.PL
(GH #170)
- AutoloadClass variables have been removed as AUTOLOAD was removed in
v4.14 so these are no longer necessary (GH #172 thanks to alexmv)
- Remove dependency on constant - internal DEBUG, XHTML_DTD and EBCDIC
constants changes to $_DEBUG, $_XHTML_DTD, and $_EBCDIC
4.13 2014-12-18
- CGI::Pretty is now DEPRECATED and will be removed in a future release.

4.11 2014-12-02
- more hash key ordering bugs fixed in HTML attribute output (GH #158,
thanks to Marcus Meissner for the patch and test case)
- escapeHTML (and unescapeHTML) have been refactored to use the functions
exported by the HTML::Entities module (GH #157)
- change BUILD_REQUIRES to TEST_REQUIRES in Makefile.PL as these are test
dependencies not build dependencies (GH #159)
- replace any remaining uses of indirect object notation (new Object) with
the safer Object->new syntax (GH #156)
4.10 2014-11-27
- favour -content-type arg in header if -type and -charset options are also
passed in (GH #155, thanks to kaoru for the test case). this change also
sorts the hash keys in the rearrange method in CGI::Util meaning the order
of the arrangement will always be the same for params that have multiple
aliases. really you shouldn't be passing in multiple aliases, but this will
make it consistent should you do that
- fix some typos
4.09 2014-10-21
- with this release the large backlog of issues against has been
cleared. All fixes have been made in the versions 4.00 and above so if

charset force numeric encoding of all characters, because that does not
- documentation tweaks for calling param() in list context and the addition
of multi_param()

"Fetching the value or values of a single named parameter" for why
this has been added and how to disable this warning

4.04 2014-09-04
- this release removes some long deprecated modules/functions and
includes refactoring to the temporary file handling in if
you are doing anything out of the ordinary with regards to temp
files you should test your code before deploying this update as
temp files may no longer be stored in previously used locations
- startform and endform methods removed (previously deprecated, you
should be using the start_form and end_form methods)
- both CGI::Apache and CGI::Switch have been removed as these modules
1) have been deprecated for *years*, and 2) do nothing whatsoever
- handle multiple values in X-Forwarded-Host header, we follow the
logic in most other frameworks and take the last value from the list
(RT #54487)
- reverse the order of TEMP dir placement for WINDOWS: TEMP > TMP > WINDIR
(RT #71799, thanks to, this returns the behaviour
to pre e24d04e9bc5fda7722444b02fec135d8cc2ff488 but with the undefined

making it act like perl's delete (RT #51020)
- add .travis.yml (
- test case for RT #53966 - disallow filenames with ~ char
- test case for RT #55166 - calling Vars to get the filename does not return
a filehandle, so this cannot be used in the call to uploadinfo, also
update documentation for the uploadInfo to show that ->Vars should not be
used to get the filename for this method

- support redirects in mod_perl2, or fall back to using env variable
for up to 5 redirects, when getting the query string (RT #36312)

- Typo fixes, (dsteinbrunner).
- use on perls 5.19.0 and later. (rjbs).
- Update CGI::Cookie docs to reflect that HttpOnly is widely supported now.
Version 3.63 Nov 12, 2012

Version 3.62, Nov 9th, 2012
- Changed how the deprecated endform function was defined for compatibility
with the development version of Perl.
- Fix failures in t/tmpdir.t when run as root, RT#80659)
- Made it possible to force a sorted order for things like hash
attributes so that tests are not dependent on a particular hash
ordering. This will be required in modern perls which will
change the ordering per process. (Yves, RT#80659)
Version 3.61 Nov 2nd, 2012
(No code changes)
- formatting of CGI::Carp documentation was improved. Thanks to benkasminbullock.
- un-TODO some tests in t/tmpdir.t that were passing in most cases.
More on this:
Version 3.60 Aug 15th, 2012
- In some caes, When unescapeHTML() hit something it didn't recognize with an ampersand and
and semicolon, it would throw away the semicolon and ampersand. It now does a better job.
of preserving content it doesn't recognize. Thanks to (RT#75595)
- Remove trailing newline after <form> tag inserted by startform and start_form. It can
cause rendering problems in some cases. Thanks to (RT#67719)

Thanks to, and Anonymous Monk
- Clarify that when -status is used, the human-readable phase should be included, per RFC 2616.
Thanks to (RT#76691).
- More tests for header(), thanks to Ryo Anazawa.

Version 3.59 Dec 29th, 2011
- We no longer read from STDIN when the Content-Length is not set, preventing
requests with no Content-Length from freezing in some cases. This is consistent
with the CGI RFC 3875, and is also consistent with CGI::Simple. However, the old
behavior may have been expected by some command-line uses of
Thanks to Philip Potter and Yanick Champoux. See RT#52469 for details:
- remove tmpdirs more aggressively. Thanks to rjbs (RT#73288)
- use Text::ParseWords instead of ancient Thanks to AlexBio.
- remove use of define(@arr). Thanks to rjbs.

- Test::More requirement has been bumped to 0.98
Version 3.56 Nov 8th, 2011
Use public and documented API in CGI::Fast
CGI::Fast was using an FCGI API that was deprecated and removed from
documentation more than ten years ago. Usage of this deprecated API with
FCGI >= 0.70 or FCGI <= 0.73 introduces a security issue.
(Thanks to chansen)
- tmp files are now cleaned up on VMS ( RT#69210, thanks to )
- Fixed test failure: done_testing() added to url.t (Thanks to Ryan Jendoubi)
- Clarify preferred bug submission location in docs, and note that Mark Stosberg
is the current maintainer.
Version 3.55 June 3rd, 2011
url() was fixed to return "PATH_INFO" when it is explicitly requested
with either the path=>1 or path_info=>1 flag.
If your code is running under mod_rewrite (or compatible) and you are calling self_url() or
you are calling url() and passing path_info=>1, These methods will actually be
returning PATH_INFO now, as you have explicitly requested, or has self_url()
has requested on your behalf.
The PATH_INFO has been omitted in such URLs since the issue was introduced
in the 3.12 release in December, 2005.
This bug is so old your application may have come to depend on it or
workaround it. Check for application before upgrading to this release.
Examples of affected method calls:
$q->url(-absolute => 1, -query => 1, -path_info => 1 )
Version 3.54, Apr 28, 2011
No code changes

Version 3.52, Jan 24, 2011
- The documentation for multi-line header handling was been updated to reflect
the changes in 3.51. (Mark Stosberg,

Version 3.51, Jan 5, 2011
- A new option to set $CGI::Carp::TO_BROWSER = 0, allows you to explicitly
exclude a particular scope from triggering printing to the browser when
fatatlsToBrowser is set. (RT#62783, Thanks to papowell)
- The <script> tag now supports the "charset" attribute.
(RT#62907, Thanks to Fabrice Metge)
- In CGI::Cookie, "Max-Age" is now supported for better spec compliance.
(Mark Stosberg)
- Setting charset() now works for all content types, not just "text/*".
(RT#57945, Thanks to Yanick and Gerv.)
- support for user temporary directories ($HOME/tmp) was commented out
in 2.61 but the documentation wasn't updated (Peter Gervai, Niko Tyni)
- setting $CGITempFile::TMPDIRECTORY before loading has been
working but undocumented since 3.12 (which listed it in Changes as
$CGI::TMPDIRECTORY) (Peter Gervai, Niko Tyni)
- unfortunately the previous change broke the runtime check for looking
for a new temporary directory if the current one suddenly became
unwritable (Peter Gervai, Niko Tyni)
- A bug was fixed in CGI::Carp triggered by certain death cases in
the BEGIN phase of parent classes.
(RT#57224, Thanks to UNERA, Yanick Champoux, Mark Stosberg)
- CGI::Cookie->new() now follows the documentation and returns undef
if the -name and -value args aren't provided. This new behavior is also
consistent with the docs and code of CGI::Simple::Cookie. (Mark Stosberg)
- CGI::Cookie->parse() now trims leading and trailing whitespace from cookie
elements as intended. The change also makes this part of the parsing
identical to CGI::Simple::Cookie (Mark Stosberg)
- Temp file handling was improved (RT#62762)
- Further improvements have been made to guard against newline injections
in headers. (Thanks to Max Kanat-Alexander, Yanick Champoux, Mark Stosberg)
- Make EBCDIC a compile-time constant so there's zero overhead (and less
compiled code) in subroutines that test for it. (Tim Bunce)
- If you just want to use CGI::Cookie, will no longer be loaded
unless you call the bake() method, which requires it. (Mark Stosberg)
- quit referring to the <link> tag as being "rarely used". (Victor Sanders)
- typo and whitespace fixes (RT#62785, thanks to
- The -dtd argument to start_html() is now documented
(RT#60473, Thanks to giecrilj and

- when creating a temporary file in the directory fails, the error message
could indicate the root of the problem better (Peter Gervai, Niko Tyni)
- Re-fixing https test in http.t. (RT#54768, thanks to SPROUT)
- param_fetch no longer triggers a warning when called with no arguments (ysth, Mark Stosberg)

Version 2.68
1. No longer attempts to escape characters when dealing with non
ISO-8861 character sets.

into document.
1. Fixed two bugs that caused the -compile pragma to fail with a
syntax error.
Version 2.67
1. Added XHTML support (incomplete; tags need to be lowercased).
2. Fixed CGI/Carp when running under mod_perl. Probably broke in
other contexts.
3. Fixed problems when passing multiple cookies.

reserved characters.
3. Minor documentation fix in javascript example.
Version 2.64

creating cookies.
3. Fixed escape() method so that +'s are treated correctly.
4. Updated CGI::Pretty module.
Version 2.53
1. Forgot to upgrade regression tests before releasing 2.52. NOTHING

running under Apache, to fix self-referencing URIs.
3. Fixed bug in escapeHTML() which caused certain constructs, such as
CGI->image_button(), to fail.
4. Fixed bug which caused strong('CGI') to fail. Be careful to use
CGI::strong('CGI') and not CGI->strong('CGI'). The latter will
produce confusing results.
5. Added upload() function, as a preferred replacement for the
"filehandle as string" feature.
6. Added cgi_error() function.
7. Rewrote file upload handling to return undef rather than dieing
when an error is encountered. Be sure to call cgi_error() to find

start_ol(), end_ol(), and so forth now work (see the docs on how
to enable this feature).

required TYPE attribute.
4. Server push primitives added, thanks to Ed Jordan.
5. Table and other HTML3 functions are now part of the :standard set.
6. Small documentation fixes.
1. Do something about the DTD mess. The module should generate
correct DTDs, or at least offer the programmer a way to specify
the correct one.
2. Split into CGI processing and HTML-generating modules.
3. More robust file upload (?still not working on the Macintosh?).
4. Bring in all the HTML4 functionality, particular the accessibility

Version 2.38
I finally got tired of all the 2.37 betas and released 2.38. The main
difference between this version and the last 2.37 beta (2.37b30) are

resolving historical inconsistencies.
25. Removed autoloader warnings about absent MultipartBuffer::DESTROY.
26. Fixed non-sticky checkbox() when -name used without -value.

41. <LAYER> and <ILAYER> added to :html3 functions.
42. Fixed problems with private tempfiles and NT/IIS systems.

4. Removed operator overloading throughout to make compatible with
new versions of perl.
5. -expires now implies the -date header, to avoid clock skew.

Version 2.30
1. Automatic detection of operating system at load time.
2. Changed select() function to Select() in order to avoid conflict

initializers took on default values from earlier CGI objects.
4. Documentation fixes.
Version 2.27
1. Small but important bug fix: the automatic capitalization of tag
attributes was accidentally capitalizing the VALUES as well as the
ATTRIBUTE names (oops).
Version 2.26
1. Changed behavior of scrolling_list(), checkbox() and
checkbox_group() methods so that defaults are honored correctly.
The "fix" causes endform() to generate additional <INPUT
TYPE="HIDDEN"> tags -- don't be surpised.
2. Fixed bug involving the detection of the SSL protocol.

2. Fixed hidden fields (again).
3. Radio_group() and checkbox_group() now return an appropriate
scalar value when called in a scalar context, rather than
returning a numeric value!

4. Made the module more configurable for different operating systems.
5. Fixed a dumb bug in JavaScript button() method.
Version 2.18
1. Fixed a bug that corrects a hang that occurs on some platforms
when processing file uploads. Unfortunately this disables the
check for bad Netscape uploads.
2. Fixed bizarre problem involving the inability to process uploaded
files that begin with a non alphabetic character in the file name.
3. Fixed a bug in the hidden fields involving the -override directive
being ignored when scalar defaults were passed.

a few more.
9. Checkbox_group() and radio_group() now return the buttons as
arrays, so that you can incorporate the individual buttons into
specialized tables.
10. Added the '-nolabels' option to checkbox_group() and
radio_group(). Probably should be added to all the other
HTML-generating routines.
11. Added the url() method to recover the URL without the entire query
string appended.
12. Added request_method() to list of environment variables available.
13. Would you believe it? Fixed hidden fields again!
Version 2.16
1. Fixed hidden fields yet again.
2. Fixed subtle problems in the file upload method that caused
intermittent failures (thanks to Keven Hendrick for this one).

request of Stephen Dahmen.
5. Added the -xbase parameter to the start_html() method, also at the
request of Stephen Dahmen.
6. Added JavaScript form buttons at Stephen's request. I'm not sure
how to use this Netscape extension correctly, however, so for now
the form() method is in the module as an undocumented feature. Use
at your own risk!
Version 2.15
1. Added the -override parameter to all field-generating methods.
2. Documented the user_name() and remote_user() methods.
3. Fixed bugs that prevented empty strings from being recognized as
valid textfield contents.
4. Documented the use of framesets and added a frameset example.
Version 2.14
This was an internal experimental version that was never released.
Version 2.13
1. Fixed a bug that interfered with the value "0" being entered into
text fields.
Version 2.01
1. Added -rows and -columns to the radio and checkbox groups. No
doubt this will cause much grief because it seems to promise a
level of meta-organization that it doesn't actually provide.
2. Fixed a bug in the redirect() method -- it was not truly HTTP/1.0
Version 2.0
The changes seemed to touch every line of code, so I decided to bump
up the major version number.
1. Support for named parameter style method calls. This turns out
to be a big win for extending when Netscape adds new HTML
2. Changed behavior of hidden fields back to the correct "sticky"
behavior. This is going to break some programs, but it is for
the best in the long run.
3. Netscape 2.0b2 broke the file upload feature. now handles
both 2.0b1 and 2.0b2-style uploading. It will probably break again
in 2.0b3.
4. There were still problems with library being unable to distinguish
between a form being loaded for the first time, and a subsequent
loading with all fields blank. We now forcibly create a default
name for the Submit button (if not provided) so that there's
always at least one parameter.
5. More workarounds to prevent annoying spurious warning messages
when run under the -w switch. -w is seriously broken in perl
Version 1.57
1. Support for the Netscape 2.0 "File upload" field.
2. The handling of defaults for selected items in scrolling lists and
multiple checkboxes is now consistent.
Version 1.56
1. Created true "pod" documentation for the module.
2. Cleaned up the code to avoid many of the spurious "use of
uninitialized variable" warnings when running with the -w switch.
3. Added the autoEscape() method. v
4. Added string interpolation of the CGI object.
5. Added the ability to pass additional parameters to the <BODY> tag.
6. Added the ability to specify the status code in the HTTP header.
Bug fixes in version 1.55
1. Every time self_url() was called, the parameter list would grow.
This was a bad "feature".
2. Documented the fact that you can pass "-" to radio_group() in
order to prevent any button from being highlighted by default.
Bug fixes in version 1.54
1. The user_agent() method is now documented;
2. A potential security hole in import() is now plugged.
3. Changed name of import() to import_names() for compatibility with
CGI:: modules.
Bug fixes in version 1.53
1. Fixed several typos in the code that were causing the following
subroutines to fail in some circumstances
1. checkbox()
2. hidden()
2. No features added
New features added in version 1.52
1. Added backslashing, quotation marks, and other shell-style escape
sequences to the parameters passed in during debugging off-line.
2. Changed the way that the hidden() method works so that the default
value always overrides the current one.
3. Improved the handling of sticky values in forms. It's now less
likely that sticky values will get stuck.
4. If you call server_name(), script_name() and several other methods
when running offline, the methods now create "dummy" values to
work with.
Bugs fixed in version 1.51
1. param() when called without arguments was returning an array of
length 1 even when there were no parameters to be had. Bad bug!
2. The HTML code generated would break if input fields contained the
forbidden characters ">< or &. You can now use these characters
New features added in version 1.50
1. import() method allows all the parameters to be imported into a
namespace in one fell swoop.
2. Parameters are now returned in the same order in which they were
Bugs fixed in version 1.45
1. delete() method didn't work correctly. This is now fixed.
2. reset() method didn't allow you to set the name of the button.
Bugs fixed in version 1.44
1. self_url() didn't include the path information. This is now fixed.
New features added in version 1.43
1. Added the delete() method.
New features added in version 1.42
1. The image_button() method to create clickable images.
2. A few bug fixes involving forms embedded in <PRE> blocks.
New features added in version 1.4
1. New header shortcut methods
+ redirect() to create HTTP redirection messages.
+ start_html() to create the HTML title, complete with the
recommended <LINK> tag that no one ever remembers to include.
+ end_html() for completeness' sake.
2. A new save() method that allows you to write out the state of an
script to a file or pipe.
3. An improved version of the new() method that allows you to restore
the state of a script from a file or pipe. With (2) this gives you
dump and restore capabilities! (Wow, you can put a "121,931
customers served" banner at the bottom of your pages!)
