993=============
994
995Release Date: August 20, 2011
996
997- Security
998
999 - An improvement was made to the MySQL and MySQLi drivers to prevent
1000 exposing a potential vector for SQL injection on sites using
1001 multi-byte character sets in the database client connection.
1002 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
1003 *mysql_set_charset()* creates a situation where using multi-byte
1004 character sets on these environments may potentially expose a SQL
1005 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
1006 character sets are unaffected on all environments.
1007
1008 If you are running or considering running a multi-byte character
1009 set for your database connection, please pay close attention to
1010 the server environment you are deploying on to ensure you are not
1011 vulnerable.
1012

1049 item was inserted successfully.
1050 - Added $this->load->get_var() to the :doc:`Loader
1051 library <libraries/loader>` to retrieve global vars set with
1052 $this->load->view() and $this->load->vars().
1053 - Changed $this->db->having() to insert quotes using escape() rather
1054 than escape_str().

1076 of all items in the cart instead of your total count.
1077- Fixed a bug where not setting 'null' when adding fields in db_forge
1078 for mysql and mysqli drivers would default to NULL instead of NOT
1079 NULL as the docs suggest.
1080- Fixed a bug where using $this->db->select_max(),
1081 $this->db->select_min(), etc could throw notices. Thanks to w43l for
1082 the patch.
1083- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
1084 whole is more reliable. This should get parameters in crontab

1205 been removed.
1206 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
1207 has been converted to a Helper and
1208 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
1209 calendar plugin was removed due to the ready availability of great
1210 JavaScript calendars, particularly with jQuery.

1218 normal routing to be overridden on a per "index" file basis.
1219 - Added the ability to set config values (or override config values)
1220 directly from data set in the main index.php file. This allows a
1221 single application to be used with multiple front controllers,
1222 each having its own config values.
1223 - Added $config['directory_trigger'] to the config file so that a
1224 controller sub-directory can be specified when running _GET
1225 strings instead of URI segments.
1226 - Added ability to set "Package" paths - specific paths where the
1227 Loader and Config classes should try to look first for a requested
1228 file. This allows distribution of sub-applications with their own
1229 libraries, models, config files, etc. in a single "package"
1230 directory. See the :doc:`Loader class <libraries/loader>`
1231 documentation for more details.

1241 from $this->dbforge->modify_column()'s 2nd param if you aren't
1242 changing the name.
1243 - $config['base_url'] is now empty by default and will guess what
1244 it should be.

1264 :doc:`Profiler <general/profiling>`
1265 - Added a wildcard option $config['allowed_types'] = '\*' to the
1266 :doc:`File Uploading Class <./libraries/file_uploading>`.
1267 - Added an 'object' config variable to the XML-RPC Server library so
1268 that one can specify the object to look for requested methods,
1269 instead of assuming it is in the $CI superobject.
1270 - Added "is_object" into the list of unit tests capable of being
1271 run.
1272 - Table library will generate an empty cell with a blank string, or
1273 NULL value.
1274 - Added ability to set tag attributes for individual cells in the
1275 Table library
1276 - Added a parse_string() method to the :doc:`Parser
1277 Class <libraries/parser>`.

1294 type value to standardize input in Upload library.
1295 - Added a second parameter (boolean) to
1296 $this->zip->read_dir('/path/to/directory', FALSE) to remove the
1297 preceding trail of empty folders when creating a Zip archive. This
1298 example would contain a zip with "directory" and all of its
1299 contents.
1300 - Added ability in the Image Library to handle PNG transparency for
1301 resize operations when using the GD lib.
1302 - Modified the Session class to prevent use if no encryption key is
1303 set in the config file.
1304 - Added a new config item to the Session class
1305 sess_expire_on_close to allow sessions to auto-expire when the

1723
1724- Libraries
1725
1726 - Added a new :doc:`Form Validation
1727 Class <libraries/form_validation>`. It simplifies setting
1728 rules and field names, supports arrays as field names, allows
1729 groups of validation rules to be saved in a config file, and adds
1730 some helper functions for use in view files. **Please note that
1731 the old Validation class is now deprecated**. We will leave it in
1732 the library folder for some time so that existing applications
1733 that use it will not break, but you are encouraged to migrate to
1734 the new version.
1735 - Updated the :doc:`Sessions class <libraries/sessions>` so that
1736 any custom data being saved gets stored to a database rather than
1737 the session cookie (assuming you are using a database to store
1738 session data), permitting much more data to be saved.
1739 - Added the ability to store libraries in subdirectories within
1740 either the main "libraries" or the local application "libraries"
1741 folder. Please see the :doc:`Loader class <libraries/loader>` for
1742 more info.
1743 - Added the ability to assign library objects to your own variable
1744 names when you use $this->load->library(). Please see the :doc:`Loader
1745 class <libraries/loader>` for more info.
1746 - Added controller class/method info to :doc:`Profiler
1747 class <general/profiling>` and support for multiple database
1748 connections.
1749 - Improved the "auto typography" feature and moved it out of the
1750 helper into its own :doc:`Typography
1751 Class <libraries/typography>`.
1752 - Improved performance and accuracy of xss_clean(), including
1753 reduction of false positives on image/file tests.
1754 - Improved :doc:`Parser class <./libraries/parser>` to allow
1755 multiple calls to the parse() function. The output of each is
1756 appended in the output.

1758 :doc:`File Upload Class <libraries/file_uploading>`.
1759 - Added set_status_header() function to :doc:`Output
1760 class <libraries/output>`.
1761 - Modified :doc:`Pagination <libraries/pagination>` class to only
1762 output the "First" link when the link for page one would not be
1763 shown.
1764 - Added support for mb_strlen in the :doc:`Form
1765 Validation <libraries/form_validation>` class so that
1766 multi-byte languages will calculate string lengths properly.
1767
1768- Database
1769
1770 - Improved Active Record class to allow full path column and table
1771 names: hostname.database.table.column. Also improved the alias

2650 whether it's supported by the server.
2651- Added the ability to :doc:`rename or relocate the "application"
2652 folder <./general/managing_apps>`.
2653- Added more thorough initialization in the upload class so that all
2654 class variables are reset.
2655- Added "is_numeric" to validation, which uses the native PHP
2656 is_numeric function.
2657- Improved the URI handler to make it more reliable when the
2658 $config['uri_protocol'] item is set to AUTO.
2659- Moved most of the functions in the Controller class into the Loader
2660 class, allowing fewer reserved function names for controllers when
2661 running under PHP 5.
2662- Updated the DB Result class to return an empty array when
2663 $query->result() doesn't produce a result.
2664- Updated the input->cookie() and input->post() functions in :doc:`Input
2665 Class <./libraries/input>` to permit arrays contained cookies
2666 that are arrays to be run through the XSS filter.
2667- Documented three functions from the Validation
2668 class that were missing from the user
2669 guide: set_select(), set_radio(), and set_checkbox().
2670- Fixed a bug in the Email class related to SMTP Helo data.
2671- Fixed a bug in the word wrapping helper and function in the email
2672 class.
2673- Fixed a bug in the validation class.
2674- Fixed a bug in the typography helper that was incorrectly wrapping
2675 block level elements in paragraph tags.
2676- Fixed a problem in the form_prep() function that was double encoding
2677 entities.
2678- Fixed a bug that affects some versions of PHP when output buffering
2679 is nested.
2680- Fixed a bug that caused CI to stop working when the PHP magic
2681 __get() or __set() functions were used within models or
2682 controllers.
2683- Fixed a pagination bug that was permitting negative values in the
2684 URL.
2685- Fixed an oversight in which the Loader class was not allowed to be
2686 extended.
2687- Changed _get_config() to get_config() since the function is not a
2688 private one.
2689- **Deprecated "init" folder**. Initialization happens automatically
2690 now. :doc:`Please see documentation <./general/creating_libraries>`.
2691- **Deprecated** $this->db->field_names() USE
2692 $this->db->list_fields()
2693- **Deprecated** the $config['log_errors'] item from the config.php
2694 file. Instead, $config['log_threshold'] can be set to "0" to turn it
2695 off.
2696
2697Version 1.4.1
2698=============
2699
2700Release Date: September 21, 2006
2701
2702- Added a new feature that passes URI segments directly to your
2703 function calls as parameters. See the
2704 :doc:`Controllers <general/controllers>` page for more info.
2705- Added support for a function named _output(), which when used in
2706 your controllers will received the final rendered output from the
2707 output class. More info in the :doc:`Controllers <general/controllers>`
2708 page.
2709- Added several new functions in the :doc:`URI
2710 Class <./libraries/uri>` to let you retrieve and manipulate URI
2711 segments that have been re-routed using the :doc:`URI
2712 Routing <general/routing>` feature. Previously, the URI class did not
2713 permit you to access any re-routed URI segments, but now it does.
2714- Added :doc:`$this->output->set_header() <./libraries/output>`
2715 function, which allows you to set server headers.
2716- Updated plugins, helpers, and language classes to allow your
2717 application folder to contain its own plugins, helpers, and language
2718 folders. Previously they were always treated as global for your
2719 entire installation. If your application folder contains any of these
2720 resources they will be used *instead* the global ones.
2721- Added :doc:`Inflector helper <./helpers/inflector_helper>`.
2722- Added element() function in the :doc:`array
2723 helper <./helpers/array_helper>`.
2724- Added RAND() to active record orderby() function.
2725- Added delete_cookie() and get_cookie() to :doc:`Cookie
2726 helper <./helpers/cookie_helper>`, even though the input class
2727 has a cookie fetching function.
2728- Added Oracle database driver (still undergoing testing so it might
2729 have some bugs).
2730- Added the ability to combine pseudo-variables and php variables in
2731 the template parser class.
2732- Added output compression option to the config file.
2733- Removed the is_numeric test from the db->escape() function.
2734- Fixed a MySQLi bug that was causing error messages not to contain
2735 proper error data.
2736- Fixed a bug in the email class which was causing it to ignore
2737 explicitly set alternative headers.
2738- Fixed a bug that was causing a PHP error when the Exceptions class
2739 was called within the get_config() function since it was causing
2740 problems.
2741- Fixed an oversight in the cookie helper in which the config file
2742 cookie settings were not being honored.
2743- Fixed an oversight in the upload class. An item mentioned in the 1.4
2744 changelog was missing.
2745- Added some code to allow email attachments to be reset when sending
2746 batches of email.
2747- Deprecated the application/scripts folder. It will continue to work
2748 for legacy users, but it is recommended that you create your own
2749 :doc:`libraries <./general/libraries>` or
2750 :doc:`models <./general/models>` instead. It was originally added
2751 before CI had user libraries or models, but it's not needed anymore.
2752- Deprecated the $autoload['core'] item from the autoload.php file.
2753 Instead, please now use: $autoload['libraries']
2754- Deprecated the following database functions:
2755 $this->db->smart_escape_str() and $this->db->fields().

2762- Added :doc:`Hooks <./general/hooks>` feature, enabling you to tap
2763 into and modify the inner workings of the framework without hacking
2764 the core files.
2765- Added the ability to organize controller files :doc:`into
2766 sub-folders <general/controllers>`. Kudos to Marco for
2767 `suggesting <http://codeigniter.com/forums/viewthread/627/>`_ this
2768 (and the next two) feature.
kenjis087a7a82011-10-20 20:08:47 +09002769- Added regular expressions support for :doc:`routing
Derek Jones8ede1a22011-10-05 13:34:52 -05002770 rules <./general/routing>`.

2779 helper.
2780- Added support for changing the port number in the :doc:`Postgres
2781 driver <./database/configuration>`.
2782- Moved the list of "allowed URI characters" out of the Router class
2783 and into the config file.
2784- Moved the MIME type array out of the Upload class and into its own
Alan Jenkinsa51f8ec2012-11-19 10:29:52 +00002785 file in the application/config/ folder.
Derek Jones8ede1a22011-10-05 13:34:52 -05002786- Updated the Upload class to allow the upload field name to be set
2787 when calling :doc:`do_upload() <./libraries/file_uploading>`.
2788- Updated the :doc:`Config Library <./libraries/config>` to be able to
2789 load config files silently, and to be able to assign config files to
2790 their own index (to avoid collisions if you use multiple config
2791 files).
2792- Updated the URI Protocol code to allow more options so that URLs will
2793 work more reliably in different environments.
2794- Updated the form_open() helper to allow the GET method to be used.
2795- Updated the MySQLi execute() function with some code to help prevent
2796 lost connection errors.
2797- Updated the SQLite Driver to check for object support before

2807 compatibility.
2808- Removed backticks from Postgres class since these are not needed.

2810 that it's a private function.
2811- Deprecated the hash() function due to a naming conflict with a native
2812 PHP function with the same name. Please use dohash() instead.
2813- Fixed an bug that was preventing the input class from unsetting GET
2814 variables.
2815- Fixed a router bug that was making it too greedy when matching end
2816 segments.
2817- Fixed a bug that was preventing multiple discrete database calls.
2818- Fixed a bug in which loading a language file was producing a "file
2819 contains no data" message.
2820- Fixed a session bug caused by the XSS Filtering feature inadvertently
2821 changing the case of certain words.
2822- Fixed some missing prefixes when using the database prefix feature.
2823- Fixed a typo in the Calendar class (cal_november).
2824- Fixed a bug in the form_checkbox() helper.

2849
2850Release Date: June 1, 2006
2851
2852- Models do **not** connect automatically to the database as of this
2853 version. :doc:`More info here <./general/models>`.
2854- Updated the Sessions class to utilize the active record class when
2855 running session related queries. Previously the queries assumed MySQL
2856 syntax.
2857- Updated alternator() function to re-initialize when called with no
2858 arguments, allowing multiple calls.
2859- Fixed a bug in the active record "having" function.
2860- Fixed a problem in the validation class which was making checkboxes

2878Release Date: April 17, 2006
2879
2880- Changed the behavior of the validation class such that if a
2881 "required" rule is NOT explicitly stated for a field then all other
2882 tests get ignored.
2883- Fixed a bug in the Controller class that was causing it to look in
2884 the local "init" folder instead of the main system one.
2885- Fixed a bug in the init_pagination file. The $config item was not
2886 being set correctly.
2887- Fixed a bug in the auto typography helper that was causing
2888 inconsistent behavior.

2894
2895Release Date: April 11, 2006

2897- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
2898- Added the ability to pass objects to the **insert()** and
2899 **update()** database functions. This feature enables you to (among
2900 other things) use your :doc:`Model class <./general/models>`
2901 variables to run queries with. See the Models page for details.
2902- Added the ability to pass objects to the :doc:`view loading
2903 function <./general/views>`: $this->load->view('my_view',
2904 $object);

Derek Jonesce79be02012-06-25 23:23:46 -07002906 class <./database/query_builder>`.
Derek Jones8ede1a22011-10-05 13:34:52 -05002907- Added count_all function to :doc:`Active Record
Derek Jonesce79be02012-06-25 23:23:46 -07002908 class <./database/query_builder>`.
Derek Jones8ede1a22011-10-05 13:34:52 -05002909- Added language file for scaffolding and fixed a scaffolding bug that
2910 occurs when there are no rows in the specified table.
2911- Added :doc:`$this->db->last_query() <./database/queries>`, which
2912 allows you to view your last query that was run.
2913- Added a new mime type to the upload class for better compatibility.
2914- Changed how cache files are read to prevent PHP errors if the cache
2915 file contains an XML tag, which PHP wants to interpret as a short
2916 tag.
2917- Fixed a bug in a couple of the active record functions (where and
2918 orderby).
2919- Fixed a bug in the image library when realpath() returns false.

2924
2925Version 1.3
2926===========
2927
2928Release Date: April 3, 2006
2929
2930- Added support for :doc:`Models <general/models>`.
2931- Redesigned the database libraries to support additional RDBMs
2932 (Postgres, MySQLi, etc.).
Derek Jonesce79be02012-06-25 23:23:46 -07002933- Redesigned the :doc:`Active Record class <./database/query_builder>`
Derek Jones8ede1a22011-10-05 13:34:52 -05002934 to enable more varied types of queries with simpler syntax, and
2935 advanced features like JOINs.
2936- Added a feature to the database class that lets you run :doc:`custom
2937 function calls <./database/call_function>`.
2938- Added support for :doc:`private functions <general/controllers>` in your
2939 controllers. Any controller function name that starts with an
2940 underscore will not be served by a URI request.
2941- Added the ability to pass your own initialization parameters to your
2942 :doc:`custom core libraries <general/creating_libraries>` when using
2943 $this->load->library()
2944- Added support for running standard :doc:`query string URLs <general/urls>`.
2945 These can be optionally enabled in your config file.
2946- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
2947 appended to your URLs. For example, you could add .html to your URLs,
2948 making them appear static. This feature is enabled in your config
2949 file.
2950- Added a new error template for use with native PHP errors.
2951- Added "alternator" function in the :doc:`string
2952 helpers <./helpers/string_helper>`.
2953- Removed slashing from the input class. After much debate we decided
2954 to kill this feature.
2955- Change the commenting style in the scripts to the PEAR standard so
2956 that IDEs and tools like phpDocumenter can harvest the comments.
2957- Added better class and function name-spacing to avoid collisions with
2958 user developed classes. All CodeIgniter classes are now prefixed with
2959 CI\_ and all controller methods are prefixed with _ci to avoid
2960 controller collisions. A list of reserved function names can be
2961 :doc:`found here <general/controllers>`.
2962- Redesigned how the "CI" super object is referenced, depending on
2963 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2964 way to manage objects that utilizes a bit less resources.
2965- Deprecated: $this->db->use_table() has been deprecated. Please read
Derek Jonesce79be02012-06-25 23:23:46 -07002966 the :doc:`Active Record <./database/query_builder>` page for
Derek Jones8ede1a22011-10-05 13:34:52 -05002967 information.
2968- Deprecated: $this->db->smart_escape_str() has been deprecated.
2969 Please use this instead: $this->db->escape()
2970- Fixed a bug in the exception handler which was preventing some PHP
2971 errors from showing up.
2972- Fixed a typo in the URI class. $this->total_segment() should be
2973 plural: $this->total_segments()
2974- Fixed some typos in the default calendar template
2975- Fixed some typos in the user guide

2980Release Date: March 21, 2006
2981
2982- Redesigned some internal aspects of the framework to resolve scoping
2983 problems that surfaced during the beta tests. The problem was most
2984 notable when instantiating classes in your constructors, particularly
2985 if those classes in turn did work in their constructors.
2986- Added a global function named
2987 :doc:`get_instance() <general/ancillary_classes>` allowing the main
2988 CodeIgniter object to be accessible throughout your own classes.
2989- Added new :doc:`File Helper <./helpers/file_helper>`:
2990 delete_files()
2991- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2992 index_page()
2993- Added the ability to create your own :doc:`core
2994 libraries <general/creating_libraries>` and store them in your local
2995 application directory.
2996- Added an overwrite option to the :doc:`Upload
2997 class <./libraries/file_uploading>`, enabling files to be
2998 overwritten rather than having the file name appended.
2999- Added Javascript Calendar plugin.
3000- Added search feature to user guide. Note: This is done using Google,
3001 which at the time of this writing has not crawled all the pages of
3002 the docs.
3003- Updated the parser class so that it allows tag pars within other tag
3004 pairs.
3005- Fixed a bug in the DB "where" function.
3006- Fixed a bug that was preventing custom config files to be
3007 auto-loaded.
