348Version 2.0.3
349=============
350
351Release Date: August 20, 2011
352
353- Security
354
355 - An improvement was made to the MySQL and MySQLi drivers to prevent
356 exposing a potential vector for SQL injection on sites using
357 multi-byte character sets in the database client connection.
358 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
359 *mysql_set_charset()* creates a situation where using multi-byte
360 character sets on these environments may potentially expose a SQL
361 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
362 character sets are unaffected on all environments.
363
364 If you are running or considering running a multi-byte character
365 set for your database connection, please pay close attention to
366 the server environment you are deploying on to ensure you are not
367 vulnerable.
368
369- General Changes

416- Added ENVIRONMENT to reserved constants. (Reactor #196)
417- Changed server check to ensure SCRIPT_NAME is defined. (Reactor #57)
418- Removed APPPATH.'third_party' from the packages autoloader to negate
419 needless file stats if no packages exist or if the developer does not
420 load any other packages by default.
421- Fixed a bug (Reactor #231) where Sessions Library database table
422 example SQL did not contain an index on last_activity. See :doc:`Upgrade
423 Notes <installation/upgrade_203>`.
424- Fixed a bug (Reactor #229) where the Sessions Library example SQL in
425 the documentation contained incorrect SQL.
426- Fixed a bug (Core #340) where when passing in the second parameter to
427 $this->db->select(), column names in subsequent queries would not be
428 properly escaped.
429- Fixed issue #199 - Attributes passed as string does not include a
430 space between it and the opening tag.
431- Fixed a bug where the method $this->cart->total_items() from :doc:`Cart
432 Library <libraries/cart>` now returns the sum of the quantity
433 of all items in the cart instead of your total count.
434- Fixed a bug where not setting 'null' when adding fields in db_forge
435 for mysql and mysqli drivers would default to NULL instead of NOT
436 NULL as the docs suggest.
437- Fixed a bug where using $this->db->select_max(),
438 $this->db->select_min(), etc could throw notices. Thanks to w43l for
439 the patch.
440- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
441 whole is more reliable. This should get parameters in crontab
442 working.

560 - PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.
561 - Scaffolding, having been deprecated for a number of versions, has
562 been removed.
563 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
564 has been converted to a Helper and
565 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
566 calendar plugin was removed due to the ready availability of great
567 JavaScript calendars, particularly with jQuery.
568 - Added new special Library type:
569 :doc:`Drivers <./general/drivers>`.
570 - Added full query-string support. See the config file for details.
571 - Moved the application folder outside of the system folder.
572 - Moved system/cache and system/logs directories to the application
573 directory.
574 - Added routing overrides to the main index.php file, enabling the
575 normal routing to be overridden on a per "index" file basis.
576 - Added the ability to set config values (or override config values)

578 single application to be used with multiple front controllers,
579 each having its own config values.
580 - Added $config['directory_trigger'] to the config file so that a
581 controller sub-directory can be specified when running _GET
582 strings instead of URI segments.
583 - Added ability to set "Package" paths - specific paths where the
584 Loader and Config classes should try to look first for a requested
585 file. This allows distribution of sub-applications with their own
586 libraries, models, config files, etc. in a single "package"
587 directory. See the :doc:`Loader class <libraries/loader>`
588 documentation for more details.
589 - In-development code is now hosted at

Derek Jones8ede1a22011-10-05 13:34:52 -0500595 now be set without an extension, the extension will be taken from
596 the uploaded file instead of the given name.
597 - In :doc:`Database Forge <database/forge>` the name can be omitted
598 from $this->dbforge->modify_column()'s 2nd param if you aren't
599 changing the name.

625 that one can specify the object to look for requested methods,
626 instead of assuming it is in the $CI superobject.
627 - Added "is_object" into the list of unit tests capable of being
628 run.
629 - Table library will generate an empty cell with a blank string, or
630 NULL value.

654 preceding trail of empty folders when creating a Zip archive. This
655 example would contain a zip with "directory" and all of its
656 contents.
657 - Added ability in the Image Library to handle PNG transparency for
658 resize operations when using the GD lib.
659 - Modified the Session class to prevent use if no encryption key is
660 set in the config file.
661 - Added a new config item to the Session class

693 Class <database/utilities>`.
694 - Semantic change to db->version() function to allow a list of

1079Hg Tag: 1.7.0
1080
1081- Libraries
1082
1083 - Added a new :doc:`Form Validation
1084 Class <libraries/form_validation>`. It simplifies setting
1085 rules and field names, supports arrays as field names, allows
1086 groups of validation rules to be saved in a config file, and adds
1087 some helper functions for use in view files. **Please note that
1088 the old Validation class is now deprecated**. We will leave it in
1089 the library folder for some time so that existing applications
1090 that use it will not break, but you are encouraged to migrate to
1091 the new version.
1092 - Updated the :doc:`Sessions class <libraries/sessions>` so that
1093 any custom data being saved gets stored to a database rather than
1094 the session cookie (assuming you are using a database to store
1095 session data), permitting much more data to be saved.
1096 - Added the ability to store libraries in subdirectories within
1097 either the main "libraries" or the local application "libraries"
1098 folder. Please see the :doc:`Loader class <libraries/loader>` for
1099 more info.
1100 - Added the ability to assign library objects to your own variable
1101 names when you use $this->load->library(). Please see the :doc:`Loader
1102 class <libraries/loader>` for more info.
1103 - Added controller class/method info to :doc:`Profiler
1104 class <general/profiling>` and support for multiple database
1105 connections.
1106 - Improved the "auto typography" feature and moved it out of the
1107 helper into its own :doc:`Typography
1108 Class <libraries/typography>`.
1109 - Improved performance and accuracy of xss_clean(), including
1110 reduction of false positives on image/file tests.
1111 - Improved :doc:`Parser class <./libraries/parser>` to allow
1112 multiple calls to the parse() function. The output of each is
1113 appended in the output.
1114 - Added max_filename option to set a file name length limit in the
1115 :doc:`File Upload Class <libraries/file_uploading>`.
1116 - Added set_status_header() function to :doc:`Output
1117 class <libraries/output>`.
1118 - Modified :doc:`Pagination <libraries/pagination>` class to only
1119 output the "First" link when the link for page one would not be
1120 shown.
1121 - Added support for mb_strlen in the :doc:`Form
1122 Validation <libraries/form_validation>` class so that
1123 multi-byte languages will calculate string lengths properly.
1124
1125- Database
1126
1127 - Improved Active Record class to allow full path column and table
1128 names: hostname.database.table.column. Also improved the alias
1129 handling.
1130 - Improved how table and column names are escaped and prefixed. It
1131 now honors full path names when adding prefixes and escaping.
1132 - Added Active Record caching feature to "update" and "delete"
1133 functions.
1134 - Added removal of non-printing control characters in escape_str()
1135 of DB drivers that do not have native PHP escaping mechanisms
1136 (mssql, oci8, odbc), to avoid potential SQL errors, and possible
1137 sources of SQL injection.
1138 - Added port support to MySQL, MySQLi, and MS SQL database drivers.
1139 - Added driver name variable in each DB driver, based on bug report
1140 #4436.
1141
1142- Helpers
1143
1144 - Added several new "setting" functions to the :doc:`Form
1145 helper <helpers/form_helper>` that allow POST data to be
1146 retrieved and set into forms. These are intended to be used on
1147 their own, or with the new :doc:`Form Validation
1148 Class <libraries/form_validation>`.
1149 - Added current_url() and uri_segments() to :doc:`URL
1150 helper <helpers/url_helper>`.
1151 - Altered auto_link() in the :doc:`URL
1152 helper <helpers/url_helper>` so that email addresses with
1153 "+" included will be linked.
1154 - Added meta() function to :doc:`HTML
1155 helper <helpers/html_helper>`.
1156 - Improved accuracy of calculations in :doc:`Number
1157 helper <helpers/number_helper>`.
1158 - Removed added newlines ("\\n") from most form and html helper
1159 functions.
1160 - Tightened up validation in the :doc:`Date
1161 helper <helpers/date_helper>` function human_to_unix(),
1162 and eliminated the POSIX regex.
1163 - Updated :doc:`Date helper <helpers/date_helper>` to match the
1164 world's current time zones and offsets.
1165 - Modified url_title() in the :doc:`URL
1166 helper <helpers/url_helper>` to remove characters and digits
1167 that are part of character entities, to allow dashes, underscores,
1168 and periods regardless of the $separator, and to allow uppercase
1169 characters.
1170 - Added support for arbitrary attributes in anchor_popup() of the
1171 :doc:`URL helper <helpers/url_helper>`.
1172
1173- Other Changes
1174
1175 - Added :doc:`PHP Style Guide <./general/styleguide>` to docs.
1176 - Added sanitization in xss_clean() for a deprecated HTML tag that
1177 could be abused in user input in Internet Explorer.
1178 - Added a few openxml document mime types, and an additional mobile
1179 agent to mimes.php and user_agents.php respectively.
1180 - Added a file lock check during caching, before trying to write to
1181 the file.
1182 - Modified Cookie key cleaning to unset a few troublesome key names
1183 that can be present in certain environments, preventing CI from
1184 halting execution.
1185 - Changed the output of the profiler to use style attribute rather
1186 than clear, and added the id "codeigniter_profiler" to the
1187 container div.

1379 Helper for using some common
1380 PHP 5 functions safely in applications that might run on PHP 4
1381 servers (thanks Seppo for the hard work and code contribution!)
1382 - Added form_button() in the :doc:`Form
1383 helper <helpers/form_helper>`.

1415 need to use them for legacy reasons, they must now be manually
1416 loaded in each Controller.

1418 the userguide, and migrated reserved controller names into it.
1419 - Added a :doc:`Common Functions <general/common_functions>` page

2097 was called within the get_config() function since it was causing
2098 problems.
2099- Fixed an oversight in the cookie helper in which the config file
2100 cookie settings were not being honored.

2104 batches of email.
2105- Deprecated the application/scripts folder. It will continue to work
2106 for legacy users, but it is recommended that you create your own
2107 :doc:`libraries <./general/libraries>` or
2108 :doc:`models <./general/models>` instead. It was originally added
2109 before CI had user libraries or models, but it's not needed anymore.
2110- Deprecated the $autoload['core'] item from the autoload.php file.
2111 Instead, please now use: $autoload['libraries']

2145 when calling :doc:`do_upload() <./libraries/file_uploading>`.
2146- Updated the :doc:`Config Library <./libraries/config>` to be able to
2147 load config files silently, and to be able to assign config files to
2148 their own index (to avoid collisions if you use multiple config
2149 files).
2150- Updated the URI Protocol code to allow more options so that URLs will
2151 work more reliably in different environments.

2239 "required" rule is NOT explicitly stated for a field then all other
2240 tests get ignored.
2241- Fixed a bug in the Controller class that was causing it to look in
2242 the local "init" folder instead of the main system one.

2305 appended to your URLs. For example, you could add .html to your URLs,
2306 making them appear static. This feature is enabled in your config
2307 file.
2308- Added a new error template for use with native PHP errors.
2309- Added "alternator" function in the :doc:`string
2310 helpers <./helpers/string_helper>`.
2311- Removed slashing from the input class. After much debate we decided
2312 to kill this feature.
2313- Change the commenting style in the scripts to the PEAR standard so
2314 that IDEs and tools like phpDocumenter can harvest the comments.
2315- Added better class and function name-spacing to avoid collisions with
2316 user developed classes. All CodeIgniter classes are now prefixed with
2317 CI\_ and all controller methods are prefixed with _ci to avoid
2318 controller collisions. A list of reserved function names can be
2319 :doc:`found here <general/controllers>`.
2320- Redesigned how the "CI" super object is referenced, depending on
2321 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2322 way to manage objects that utilizes a bit less resources.
2323- Deprecated: $this->db->use_table() has been deprecated. Please read
2324 the :doc:`Active Record <./database/active_record>` page for
2325 information.
2326- Deprecated: $this->db->smart_escape_str() has been deprecated.
2327 Please use this instead: $this->db->escape()
2328- Fixed a bug in the exception handler which was preventing some PHP
2329 errors from showing up.
2330- Fixed a typo in the URI class. $this->total_segment() should be
2331 plural: $this->total_segments()
2332- Fixed some typos in the default calendar template
2333- Fixed some typos in the user guide

2338Release Date: March 21, 2006
2339
2340- Redesigned some internal aspects of the framework to resolve scoping
2341 problems that surfaced during the beta tests. The problem was most
2342 notable when instantiating classes in your constructors, particularly
2343 if those classes in turn did work in their constructors.

2348 delete_files()
2349- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2350 index_page()
2351- Added the ability to create your own :doc:`core
2352 libraries <general/creating_libraries>` and store them in your local
2353 application directory.
2354- Added an overwrite option to the :doc:`Upload
2355 class <./libraries/file_uploading>`, enabling files to be
2356 overwritten rather than having the file name appended.
2357- Added Javascript Calendar plugin.
2358- Added search feature to user guide. Note: This is done using Google,
2359 which at the time of this writing has not crawled all the pages of
2360 the docs.
2361- Updated the parser class so that it allows tag pars within other tag
2362 pairs.
2363- Fixed a bug in the DB "where" function.
