321 turn automatic indexes back on.
322 7. The url() and self_url() methods now work better in the context of Apache
323 mod_rewrite. Be advised that path_info() may give you confusing results
324 when mod_rewrite is active because Apache calculates the path info *after*
325 rewriting. This is mostly worked around in url() and self_url(), but you
326 may notice some anomalies.
327 8. Removed empty (and non-validating) <div> from code emitted by end_form().
328 9. Fixed CGI::Carp to work correctly with Mod_perl 1.29 in an Apache 2 environment.

334 3. Workaround for a bug that appears in Apache2 versions through 2.0.54
335 in which SCRIPT_NAME and PATH_INFO are incorrect if the additional path_info
336 contains a double slash. This workaround will handle the common case of
337 http://mysite.com/cgi-bin/log.cgi/http://www.some.other.site/args, but will
338 not handle the uncommon case of a ScriptAlias directive that adds additional
339 path information to the end of the translated URI.
342 1. Added Apache2::RequestIO, which is necessary for mp2 interoperability.
345 1. Fixed tabindex="0" when using CGI to create forms without a prior start_html
346 2. Removed warning about non-numeric MOD_PERL_API_VERSION.

363 4. autoEscape() flag is now respected when generating extra
365 5. Tests for *tag start/end generation from Shlomi Fish.
366 6. Support for can() method provided by Ron Savage.
367 7. Fix for lang='' when outputting XHTML.
368 8. Added support for chunked transfer encoding, as suggested by
370 9. Fixed clobbering of row and column headers in tableized radio
371 and checkbox groups, as reported by Nicolas Thierry-Mieg.
372 10. <Label> tags are now associated with form elements, as suggested
373 by accessibility guidelines.
374 11. The <?xml> directive produced by start_html is now turned off by
375 default and the charset is specified in a <meta> directive. Apparently
376 IE6 (and maybe some versions of Opera) were getting confused by this.
377 12. Support for tab indexes.
378 13. Retired the HTML docs. The POD docs are now primary documentation.
379 14. CGI::Carp now correctly detects and handles Apache::Dispatch.
380 15. CGI::Util::utf8_chr now correctly sets the UTF8 flag on 5.006 or
381 higher perls (fix courtesy Slaven Rezic).
386 1. Fixed uninitialized variable warning on start_form() when running
388 2. Fixed CGI::_set_attributes so that attributes with a - are handled
390 3. Fixed CGI::Carp::die() so as to avoid problems from _longmess()
392 4. If HTTP_X_FORWARDED_HOST is defined (i.e. running under a proxy),
393 the various functions that return HOST will use that instead.
394 5. Fix for undefined utf8() call in CGI::Util.
395 6. Changed the call to warningsToBrowser() in
396 CGI::Carp::fatalsToBrowser to call only after HTTP header is sent

400 8. Fixed an extraneous "foo=bar" appearing when extra style
401 parameters passed to start_html;

407 12. Fixed query string stripping in order to handle URLs containing
409 13. During server push, set NPH to 0 rather than 1. This is supposed
410 to fix problems with Apache.
411 14. Fixed incorrect processing of multipart form fields that contain
412 embedded quotes. There's still the issue of how to handle ones
413 that contain embedded semicolons, but no one has complained (yet).
414 15. Fixed documentation bug in -style argument to start_html()
415 16. Added -status argument to redirect().
419 1. Fixed the problem with mod_perl crashing when "defaults" button

442 5. Added upload_hook functionality from Jamie LeTaul
443 6. Workarounds for mod_perl 2 IO issues. Check that file upload and
444 state saving still working.
445 7. Added code for underreads.
446 8. Fixed misleading description of redirect() and relative URLs in
448 9. Workaround for weird interaction of CGI::Carp with Safe module

1258 3. Radio_group() and checkbox_group() now return an appropriate
1259 scalar value when called in a scalar context, rather than
1260 returning a numeric value!
1261 4. Cleaned up the formatting of form elements to avoid unesthetic
1262 extra spaces within the attributes.
1263 5. HTML elements now correctly include the closing tag when
1264 parameters are present but null: em('')
1265 6. Added password_field() to the export list.
1269 1. Dumped the SelfLoader because of problems with running with taint
1270 checks and rolled my own. Performance is now significantly
1272 2. Added HTML shortcuts.
1273 3. import() now adheres to the Perl module conventions, allowing
1274 CGI.pm to import any or all method names into the user's name
1276 4. Added the ability to initialize CGI objects from strings and
1278 5. Made it possible to initialize CGI objects with filehandle
1279 references rather than filehandle strings.
1280 6. Added the delete_all() and append() methods.
1281 7. CGI objects correctly initialize from filehandles on NT/95 systems
1283 8. Fixed the problem with binary file uploads on NT/95 systems.
1284 9. Fixed bug in redirect().
1285 10. Added '-Window-target' parameter to redirect().
1286 11. Fixed import_names() so that parameter names containing funny
1288 12. Broke the unfortunate connection between cookie and CGI parameter
1290 13. Fixed problems with hidden fields whose values are 0.
1291 14. Cleaned up the documentation somewhat.
1295 1. Added cookie() support routines.
1296 2. Added -expires parameter to header().
1297 3. Added cgi-lib.pl compatability mode.
1298 4. Made the module more configurable for different operating systems.
1299 5. Fixed a dumb bug in JavaScript button() method.
1303 1. Fixed a bug that corrects a hang that occurs on some platforms
1304 when processing file uploads. Unfortunately this disables the
1305 check for bad Netscape uploads.
1306 2. Fixed bizarre problem involving the inability to process uploaded
1307 files that begin with a non alphabetic character in the file name.
1308 3. Fixed a bug in the hidden fields involving the -override directive
1309 being ignored when scalar defaults were passed.
1310 4. Added documentation on how to disable the SelfLoader features.
1314 1. Added support for the SelfLoader module.
1315 2. Added oodles of JavaScript support routines.
1316 3. Fixed bad bug in query_string() method that caused some parameters
1317 to be silently dropped.
1318 4. Robustified file upload code to handle premature termination by
1320 5. Exported temporary file names on file upload.
1321 6. Removed spurious "uninitialized variable" warnings that appeared
1322 when running under 5.002.
1323 7. Added the Carp.pm library to the standard distribution.
1324 8. Fixed a number of errors in this documentation, and probably added
1326 9. Checkbox_group() and radio_group() now return the buttons as
1327 arrays, so that you can incorporate the individual buttons into
1329 10. Added the '-nolabels' option to checkbox_group() and
1330 radio_group(). Probably should be added to all the other
1331 HTML-generating routines.
1332 11. Added the url() method to recover the URL without the entire query
1334 12. Added request_method() to list of environment variables available.
1335 13. Would you believe it? Fixed hidden fields again!
1339 1. Fixed hidden fields yet again.
1340 2. Fixed subtle problems in the file upload method that caused
1341 intermittent failures (thanks to Keven Hendrick for this one).
1342 3. Made file upload more robust in the face of bizarre behavior by
1343 the Macintosh and Windows Netscape clients.
1344 4. Moved the POD documentation to the bottom of the module at the
1345 request of Stephen Dahmen.
1346 5. Added the -xbase parameter to the start_html() method, also at the
1347 request of Stephen Dahmen.
1348 6. Added JavaScript form buttons at Stephen's request. I'm not sure
1349 how to use this Netscape extension correctly, however, so for now
1350 the form() method is in the module as an undocumented feature. Use
1355 1. Added the -override parameter to all field-generating methods.
1356 2. Documented the user_name() and remote_user() methods.
1357 3. Fixed bugs that prevented empty strings from being recognized as
1358 valid textfield contents.
1359 4. Documented the use of framesets and added a frameset example.
1363 This was an internal experimental version that was never released.
1367 1. Fixed a bug that interfered with the value "0" being entered into
1372 1. Added -rows and -columns to the radio and checkbox groups. No
1373 doubt this will cause much grief because it seems to promise a
1374 level of meta-organization that it doesn't actually provide.
1375 2. Fixed a bug in the redirect() method -- it was not truly HTTP/1.0
1380 The changes seemed to touch every line of code, so I decided to bump
1381 up the major version number.
1382 1. Support for named parameter style method calls. This turns out
1383 to be a big win for extending CGI.pm when Netscape adds new HTML
1385 2. Changed behavior of hidden fields back to the correct "sticky"
1386 behavior. This is going to break some programs, but it is for
1387 the best in the long run.
1388 3. Netscape 2.0b2 broke the file upload feature. CGI.pm now handles
1389 both 2.0b1 and 2.0b2-style uploading. It will probably break again
1391 4. There were still problems with library being unable to distinguish
1392 between a form being loaded for the first time, and a subsequent
1393 loading with all fields blank. We now forcibly create a default
1394 name for the Submit button (if not provided) so that there's
1395 always at least one parameter.
1396 5. More workarounds to prevent annoying spurious warning messages
1397 when run under the -w switch. -w is seriously broken in perl
1402 1. Support for the Netscape 2.0 "File upload" field.
1403 2. The handling of defaults for selected items in scrolling lists and
1404 multiple checkboxes is now consistent.
1408 1. Created true "pod" documentation for the module.
1409 2. Cleaned up the code to avoid many of the spurious "use of
1410 uninitialized variable" warnings when running with the -w switch.
1411 3. Added the autoEscape() method. v
1412 4. Added string interpolation of the CGI object.
1413 5. Added the ability to pass additional parameters to the <BODY> tag.
1414 6. Added the ability to specify the status code in the HTTP header.
1416 Bug fixes in version 1.55
1418 1. Every time self_url() was called, the parameter list would grow.
1419 This was a bad "feature".
1420 2. Documented the fact that you can pass "-" to radio_group() in
1421 order to prevent any button from being highlighted by default.
1423 Bug fixes in version 1.54
1425 1. The user_agent() method is now documented;
1426 2. A potential security hole in import() is now plugged.
1427 3. Changed name of import() to import_names() for compatability with
1430 Bug fixes in version 1.53
1432 1. Fixed several typos in the code that were causing the following
1433 subroutines to fail in some circumstances
1436 2. No features added
1438 New features added in version 1.52
1440 1. Added backslashing, quotation marks, and other shell-style escape
1441 sequences to the parameters passed in during debugging off-line.
1442 2. Changed the way that the hidden() method works so that the default
1443 value always overrides the current one.
1444 3. Improved the handling of sticky values in forms. It's now less
1445 likely that sticky values will get stuck.
1446 4. If you call server_name(), script_name() and several other methods
1447 when running offline, the methods now create "dummy" values to
1450 Bugs fixed in version 1.51
1452 1. param() when called without arguments was returning an array of
1453 length 1 even when there were no parameters to be had. Bad bug!
1455 2. The HTML code generated would break if input fields contained the
1456 forbidden characters ">< or &. You can now use these characters
1459 New features added in version 1.50
1461 1. import() method allows all the parameters to be imported into a
1462 namespace in one fell swoop.
1463 2. Parameters are now returned in the same order in which they were
1466 Bugs fixed in version 1.45
1468 1. delete() method didn't work correctly. This is now fixed.
1469 2. reset() method didn't allow you to set the name of the button.
1472 Bugs fixed in version 1.44
1474 1. self_url() didn't include the path information. This is now fixed.
1476 New features added in version 1.43
1478 1. Added the delete() method.
1480 New features added in version 1.42
1482 1. The image_button() method to create clickable images.
1483 2. A few bug fixes involving forms embedded in <PRE> blocks.
1485 New features added in version 1.4
1487 1. New header shortcut methods
1488 + redirect() to create HTTP redirection messages.
1489 + start_html() to create the HTML title, complete with the
1490 recommended <LINK> tag that no one ever remembers to include.
1491 + end_html() for completeness' sake.
1492 2. A new save() method that allows you to write out the state of an
1493 script to a file or pipe.
1494 3. An improved version of the new() method that allows you to restore
1495 the state of a script from a file or pipe. With (2) this gives you
1496 dump and restore capabilities! (Wow, you can put a "121,931
1497 customers served" banner at the bottom of your pages!)
1498 4. A self_url() method that allows you to create state-maintaining
1499 hypertext links. In addition to allowing you to maintain the state
1500 of your scripts between invocations, this lets you work around a
1501 problem that some browsers have when jumping to internal links in
1502 a document that contains a form -- the form information gets lost.
1503 5. The user-visible labels in checkboxes, radio buttons, popup menus
1504 and scrolling lists have now been decoupled from the values sent
1505 to your CGI script. Your script can know a checkbox by the name of
1506 "cb1" while the user knows it by a more descriptive name. I've
1507 also added some parameters that were missing from the text fields,
1509 6. A whole bunch of methods have been added to get at environment
1510 variables involved in user verification and other obscure
1515 1. The problems with the hidden fields have (I hope at last) been
1517 2. You can create multiple query objects and they will all be
1518 initialized correctly. This simplifies the creation of multiple
1520 3. The URL unescaping code works correctly now.
