1135=============
1136
1137Release Date: August 20, 2011
1138
1139- Security
1140
1141 - An improvement was made to the MySQL and MySQLi drivers to prevent
1142 exposing a potential vector for SQL injection on sites using
1143 multi-byte character sets in the database client connection.
1144 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
1145 *mysql_set_charset()* creates a situation where using multi-byte
1146 character sets on these environments may potentially expose a SQL
1147 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
1148 character sets are unaffected on all environments.
1149
1150 If you are running or considering running a multi-byte character
1151 set for your database connection, please pay close attention to
1152 the server environment you are deploying on to ensure you are not
1153 vulnerable.
1154

1180 helper <helpers/inflector_helper>` to support considerably
1181 more words.
1182

1191 item was inserted successfully.
1192 - Added $this->load->get_var() to the :doc:`Loader
1193 library <libraries/loader>` to retrieve global vars set with
1194 $this->load->view() and $this->load->vars().
1195 - Changed $this->db->having() to insert quotes using escape() rather
1196 than escape_str().
1197

1218 of all items in the cart instead of your total count.
1219- Fixed a bug where not setting 'null' when adding fields in db_forge
1220 for mysql and mysqli drivers would default to NULL instead of NOT
1221 NULL as the docs suggest.
1222- Fixed a bug where using $this->db->select_max(),
1223 $this->db->select_min(), etc could throw notices. Thanks to w43l for
1224 the patch.
1225- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
1226 whole is more reliable. This should get parameters in crontab
1227 working.

1343 been removed.
1344 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
1345 has been converted to a Helper and
1346 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
1347 calendar plugin was removed due to the ready availability of great
1348 JavaScript calendars, particularly with jQuery.

1356 normal routing to be overridden on a per "index" file basis.
1357 - Added the ability to set config values (or override config values)
1358 directly from data set in the main index.php file. This allows a
1359 single application to be used with multiple front controllers,
1360 each having its own config values.
1361 - Added $config['directory_trigger'] to the config file so that a
1362 controller sub-directory can be specified when running _GET
1363 strings instead of URI segments.
1364 - Added ability to set "Package" paths - specific paths where the
1365 Loader and Config classes should try to look first for a requested
1366 file. This allows distribution of sub-applications with their own
1367 libraries, models, config files, etc. in a single "package"
1368 directory. See the :doc:`Loader class <libraries/loader>`
1369 documentation for more details.

1378 from $this->dbforge->modify_column()'s 2nd param if you aren't
1379 changing the name.
1380 - $config['base_url'] is now empty by default and will guess what
1381 it should be.

1405 that one can specify the object to look for requested methods,
1406 instead of assuming it is in the $CI superobject.
1407 - Added "is_object" into the list of unit tests capable of being
1408 run.
1409 - Table library will generate an empty cell with a blank string, or
1410 NULL value.

1431 type value to standardize input in Upload library.
1432 - Added a second parameter (boolean) to
1433 $this->zip->read_dir('/path/to/directory', FALSE) to remove the
1434 preceding trail of empty folders when creating a Zip archive. This
1435 example would contain a zip with "directory" and all of its
1436 contents.
1437 - Added ability in the Image Library to handle PNG transparency for
1438 resize operations when using the GD lib.
1439 - Modified the Session class to prevent use if no encryption key is

1519 helper <./helpers/html_helper>` will now generate an empty
1520 string as an alt attribute if one is not provided.
1521 - If CSRF is enabled in the application config file, form_open()
1522 will automatically insert it as a hidden field.
1523 - Added sanitize_filename() into the :doc:`Security
1524 helper <./helpers/security_helper>`.
1525 - Added ellipsize() to the :doc:`Text
1526 Helper <./helpers/text_helper>`

1538 - Increased randomness with is_really_writable() to avoid file
1539 collisions when hundreds or thousands of requests occur at once.
1540 - Switched some DIR_WRITE_MODE constant uses to FILE_WRITE_MODE
1541 where files and not directories are being operated on.

1548 - Updated the output library to no longer compress output or send
1549 content-length headers if the server runs with

1860
1861- Libraries
1862
1863 - Added a new :doc:`Form Validation
1864 Class <libraries/form_validation>`. It simplifies setting
1865 rules and field names, supports arrays as field names, allows
1866 groups of validation rules to be saved in a config file, and adds
1867 some helper functions for use in view files. **Please note that
1868 the old Validation class is now deprecated**. We will leave it in
1869 the library folder for some time so that existing applications
1870 that use it will not break, but you are encouraged to migrate to
1871 the new version.
1872 - Updated the :doc:`Sessions class <libraries/sessions>` so that
1873 any custom data being saved gets stored to a database rather than
1874 the session cookie (assuming you are using a database to store
1875 session data), permitting much more data to be saved.
1876 - Added the ability to store libraries in subdirectories within
1877 either the main "libraries" or the local application "libraries"
1878 folder. Please see the :doc:`Loader class <libraries/loader>` for
1879 more info.
1880 - Added the ability to assign library objects to your own variable
1881 names when you use $this->load->library(). Please see the :doc:`Loader
1882 class <libraries/loader>` for more info.
1883 - Added controller class/method info to :doc:`Profiler
1884 class <general/profiling>` and support for multiple database
1885 connections.

1887 helper into its own :doc:`Typography
1888 Class <libraries/typography>`.
1889 - Improved performance and accuracy of xss_clean(), including
1890 reduction of false positives on image/file tests.
1891 - Improved :doc:`Parser class <./libraries/parser>` to allow
1892 multiple calls to the parse() function. The output of each is
1893 appended in the output.

1895 :doc:`File Upload Class <libraries/file_uploading>`.
1896 - Added set_status_header() function to :doc:`Output
1897 class <libraries/output>`.
1898 - Modified :doc:`Pagination <libraries/pagination>` class to only

1900 shown.
1901 - Added support for mb_strlen in the :doc:`Form
1902 Validation <libraries/form_validation>` class so that
1903 multi-byte languages will calculate string lengths properly.
1904
1905- Database
1906
1907 - Improved Active Record class to allow full path column and table
1908 names: hostname.database.table.column. Also improved the alias
1909 handling.
1910 - Improved how table and column names are escaped and prefixed. It
1911 now honors full path names when adding prefixes and escaping.
1912 - Added Active Record caching feature to "update" and "delete"
1913 functions.
1914 - Added removal of non-printing control characters in escape_str()
1915 of DB drivers that do not have native PHP escaping mechanisms
1916 (mssql, oci8, odbc), to avoid potential SQL errors, and possible
1917 sources of SQL injection.
1918 - Added port support to MySQL, MySQLi, and MS SQL database drivers.
1919 - Added driver name variable in each DB driver, based on bug report
1920 #4436.
1921
1922- Helpers
1923
1924 - Added several new "setting" functions to the :doc:`Form
1925 helper <helpers/form_helper>` that allow POST data to be
1926 retrieved and set into forms. These are intended to be used on
1927 their own, or with the new :doc:`Form Validation
1928 Class <libraries/form_validation>`.
1929 - Added current_url() and uri_segments() to :doc:`URL
1930 helper <helpers/url_helper>`.
1931 - Altered auto_link() in the :doc:`URL
1932 helper <helpers/url_helper>` so that email addresses with
1933 "+" included will be linked.
1934 - Added meta() function to :doc:`HTML
1935 helper <helpers/html_helper>`.
1936 - Improved accuracy of calculations in :doc:`Number
1937 helper <helpers/number_helper>`.

1941 helper <helpers/date_helper>` function human_to_unix(),
1942 and eliminated the POSIX regex.
1943 - Updated :doc:`Date helper <helpers/date_helper>` to match the
1944 world's current time zones and offsets.
1945 - Modified url_title() in the :doc:`URL
1946 helper <helpers/url_helper>` to remove characters and digits
1947 that are part of character entities, to allow dashes, underscores,
1948 and periods regardless of the $separator, and to allow uppercase
1949 characters.
1950 - Added support for arbitrary attributes in anchor_popup() of the
1951 :doc:`URL helper <helpers/url_helper>`.
1952
1953- Other Changes
1954
1955 - Added :doc:`PHP Style Guide <./general/styleguide>` to docs.
1956 - Added sanitization in xss_clean() for a deprecated HTML tag that
1957 could be abused in user input in Internet Explorer.

2837Release Date: September 21, 2006
2838
2839- Added a new feature that passes URI segments directly to your
2840 function calls as parameters. See the
2841 :doc:`Controllers <general/controllers>` page for more info.
2842- Added support for a function named _output(), which when used in
2843 your controllers will received the final rendered output from the
2844 output class. More info in the :doc:`Controllers <general/controllers>`
2845 page.
2846- Added several new functions in the :doc:`URI
2847 Class <./libraries/uri>` to let you retrieve and manipulate URI
2848 segments that have been re-routed using the :doc:`URI
2849 Routing <general/routing>` feature. Previously, the URI class did not
2850 permit you to access any re-routed URI segments, but now it does.
2851- Added :doc:`$this->output->set_header() <./libraries/output>`
2852 function, which allows you to set server headers.
2853- Updated plugins, helpers, and language classes to allow your
2854 application folder to contain its own plugins, helpers, and language
2855 folders. Previously they were always treated as global for your
2856 entire installation. If your application folder contains any of these
2857 resources they will be used *instead* the global ones.
2858- Added :doc:`Inflector helper <./helpers/inflector_helper>`.
2859- Added element() function in the :doc:`array
2860 helper <./helpers/array_helper>`.
2861- Added RAND() to active record orderby() function.
2862- Added delete_cookie() and get_cookie() to :doc:`Cookie
2863 helper <./helpers/cookie_helper>`, even though the input class
2864 has a cookie fetching function.
2865- Added Oracle database driver (still undergoing testing so it might
2866 have some bugs).
2867- Added the ability to combine pseudo-variables and php variables in
2868 the template parser class.
2869- Added output compression option to the config file.
2870- Removed the is_numeric test from the db->escape() function.
2871- Fixed a MySQLi bug that was causing error messages not to contain
2872 proper error data.
2873- Fixed a bug in the email class which was causing it to ignore
2874 explicitly set alternative headers.
2875- Fixed a bug that was causing a PHP error when the Exceptions class
2876 was called within the get_config() function since it was causing
2877 problems.
2878- Fixed an oversight in the cookie helper in which the config file
2879 cookie settings were not being honored.
2880- Fixed an oversight in the upload class. An item mentioned in the 1.4
2881 changelog was missing.
2882- Added some code to allow email attachments to be reset when sending
2883 batches of email.
2884- Deprecated the application/scripts folder. It will continue to work
2885 for legacy users, but it is recommended that you create your own
2886 :doc:`libraries <./general/libraries>` or
2887 :doc:`models <./general/models>` instead. It was originally added
2888 before CI had user libraries or models, but it's not needed anymore.
2889- Deprecated the $autoload['core'] item from the autoload.php file.
2890 Instead, please now use: $autoload['libraries']
2891- Deprecated the following database functions:
2892 $this->db->smart_escape_str() and $this->db->fields().
2893

2896
2897Release Date: September 17, 2006
2898
2899- Added :doc:`Hooks <./general/hooks>` feature, enabling you to tap
2900 into and modify the inner workings of the framework without hacking
2901 the core files.
2902- Added the ability to organize controller files :doc:`into
2903 sub-folders <general/controllers>`. Kudos to Marco for
Master Yodabd2a7e42015-03-25 02:36:31 -07002904 suggesting this (and the next two) feature.
kenjis087a7a82011-10-20 20:08:47 +09002905- Added regular expressions support for :doc:`routing
Derek Jones8ede1a22011-10-05 13:34:52 -05002906 rules <./general/routing>`.
2907- Added the ability to :doc:`remap function
2908 calls <./general/controllers>` within your controllers.

2915 helper.
2916- Added support for changing the port number in the :doc:`Postgres
2917 driver <./database/configuration>`.
2918- Moved the list of "allowed URI characters" out of the Router class
2919 and into the config file.
2920- Moved the MIME type array out of the Upload class and into its own
Alan Jenkinsa51f8ec2012-11-19 10:29:52 +00002921 file in the application/config/ folder.
Derek Jones8ede1a22011-10-05 13:34:52 -05002922- Updated the Upload class to allow the upload field name to be set
2923 when calling :doc:`do_upload() <./libraries/file_uploading>`.
2924- Updated the :doc:`Config Library <./libraries/config>` to be able to
2925 load config files silently, and to be able to assign config files to
2926 their own index (to avoid collisions if you use multiple config
2927 files).
2928- Updated the URI Protocol code to allow more options so that URLs will
2929 work more reliably in different environments.
2930- Updated the form_open() helper to allow the GET method to be used.
2931- Updated the MySQLi execute() function with some code to help prevent
2932 lost connection errors.
2933- Updated the SQLite Driver to check for object support before
2934 attempting to return results as objects. If unsupported it returns an
2935 array.

2937 same model.
2938- Updated the MS SQL driver so that single quotes are escaped.

2943 compatibility.
2944- Removed backticks from Postgres class since these are not needed.
2945- Renamed display() to _display() in the Output class to make it clear
2946 that it's a private function.
2947- Deprecated the hash() function due to a naming conflict with a native
2948 PHP function with the same name. Please use dohash() instead.
2949- Fixed an bug that was preventing the input class from unsetting GET
2950 variables.
2951- Fixed a router bug that was making it too greedy when matching end
2952 segments.
2953- Fixed a bug that was preventing multiple discrete database calls.
2954- Fixed a bug in which loading a language file was producing a "file
2955 contains no data" message.
2956- Fixed a session bug caused by the XSS Filtering feature inadvertently
2957 changing the case of certain words.
2958- Fixed some missing prefixes when using the database prefix feature.
2959- Fixed a typo in the Calendar class (cal_november).
2960- Fixed a bug in the form_checkbox() helper.
2961- Fixed a bug that was allowing the second segment of the URI to be
2962 identical to the class name.

2975 being called properly.
2976- Fixed a bug in the validation class that was not permitting callbacks
2977 if the form field was empty.
2978- Fixed a problem that was preventing scaffolding from working properly
2979 with MySQLi.
2980- Fixed some MS SQL bugs.
2981- Fixed some doc typos.
2982
2983Version 1.3.3
2984=============
2985
2986Release Date: June 1, 2006
2987
2988- Models do **not** connect automatically to the database as of this
2989 version. :doc:`More info here <./general/models>`.
2990- Updated the Sessions class to utilize the active record class when
2991 running session related queries. Previously the queries assumed MySQL
2992 syntax.
2993- Updated alternator() function to re-initialize when called with no
2994 arguments, allowing multiple calls.
2995- Fixed a bug in the active record "having" function.
2996- Fixed a problem in the validation class which was making checkboxes
2997 be ignored when required.
2998- Fixed a bug in the word_limiter() helper function. It was cutting
2999 off the fist word.
3000- Fixed a bug in the xss_clean function due to a PHP bug that affects
3001 some versions of html_entity_decode.
3002- Fixed a validation bug that was preventing rules from being set twice
3003 in one controller.

3012=============
3013
3014Release Date: April 17, 2006
3015
3016- Changed the behavior of the validation class such that if a
3017 "required" rule is NOT explicitly stated for a field then all other
3018 tests get ignored.
3019- Fixed a bug in the Controller class that was causing it to look in
3020 the local "init" folder instead of the main system one.
3021- Fixed a bug in the init_pagination file. The $config item was not
3022 being set correctly.
3023- Fixed a bug in the auto typography helper that was causing
3024 inconsistent behavior.

3030
3031Release Date: April 11, 2006

3033- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
3034- Added the ability to pass objects to the **insert()** and
3035 **update()** database functions. This feature enables you to (among
3036 other things) use your :doc:`Model class <./general/models>`
3037 variables to run queries with. See the Models page for details.
3038- Added the ability to pass objects to the :doc:`view loading
3039 function <./general/views>`: $this->load->view('my_view',
3040 $object);

Derek Jonesce79be02012-06-25 23:23:46 -07003044 class <./database/query_builder>`.
Derek Jones8ede1a22011-10-05 13:34:52 -05003045- Added language file for scaffolding and fixed a scaffolding bug that
3046 occurs when there are no rows in the specified table.
3047- Added :doc:`$this->db->last_query() <./database/queries>`, which
3048 allows you to view your last query that was run.
3049- Added a new mime type to the upload class for better compatibility.
3050- Changed how cache files are read to prevent PHP errors if the cache
3051 file contains an XML tag, which PHP wants to interpret as a short
3052 tag.
3053- Fixed a bug in a couple of the active record functions (where and
3054 orderby).
3055- Fixed a bug in the image library when realpath() returns false.

3060
3061Version 1.3
3062===========
3063
3064Release Date: April 3, 2006
3065
3066- Added support for :doc:`Models <general/models>`.
3067- Redesigned the database libraries to support additional RDBMs
3068 (Postgres, MySQLi, etc.).
Derek Jonesce79be02012-06-25 23:23:46 -07003069- Redesigned the :doc:`Active Record class <./database/query_builder>`
Derek Jones8ede1a22011-10-05 13:34:52 -05003070 to enable more varied types of queries with simpler syntax, and
3071 advanced features like JOINs.
3072- Added a feature to the database class that lets you run :doc:`custom
3073 function calls <./database/call_function>`.
3074- Added support for :doc:`private functions <general/controllers>` in your
3075 controllers. Any controller function name that starts with an
3076 underscore will not be served by a URI request.
3077- Added the ability to pass your own initialization parameters to your
3078 :doc:`custom core libraries <general/creating_libraries>` when using
3079 $this->load->library()
3080- Added support for running standard :doc:`query string URLs <general/urls>`.
3081 These can be optionally enabled in your config file.
3082- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
3083 appended to your URLs. For example, you could add .html to your URLs,
3084 making them appear static. This feature is enabled in your config
3085 file.
3086- Added a new error template for use with native PHP errors.
3087- Added "alternator" function in the :doc:`string
3088 helpers <./helpers/string_helper>`.
3089- Removed slashing from the input class. After much debate we decided
3090 to kill this feature.
3091- Change the commenting style in the scripts to the PEAR standard so
3092 that IDEs and tools like phpDocumenter can harvest the comments.
3093- Added better class and function name-spacing to avoid collisions with
3094 user developed classes. All CodeIgniter classes are now prefixed with
3095 CI\_ and all controller methods are prefixed with _ci to avoid
3096 controller collisions. A list of reserved function names can be
3097 :doc:`found here <general/controllers>`.
3098- Redesigned how the "CI" super object is referenced, depending on
3099 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
3100 way to manage objects that utilizes a bit less resources.
3101- Deprecated: $this->db->use_table() has been deprecated. Please read
Derek Jonesce79be02012-06-25 23:23:46 -07003102 the :doc:`Active Record <./database/query_builder>` page for
Derek Jones8ede1a22011-10-05 13:34:52 -05003103 information.
3104- Deprecated: $this->db->smart_escape_str() has been deprecated.
3105 Please use this instead: $this->db->escape()
3106- Fixed a bug in the exception handler which was preventing some PHP
3107 errors from showing up.
3108- Fixed a typo in the URI class. $this->total_segment() should be
3109 plural: $this->total_segments()
3110- Fixed some typos in the default calendar template
3111- Fixed some typos in the user guide
3112

3114===========
3115
3116Release Date: March 21, 2006
3117
3118- Redesigned some internal aspects of the framework to resolve scoping
3119 problems that surfaced during the beta tests. The problem was most
3120 notable when instantiating classes in your constructors, particularly
3121 if those classes in turn did work in their constructors.
3122- Added a global function named
3123 :doc:`get_instance() <general/ancillary_classes>` allowing the main
3124 CodeIgniter object to be accessible throughout your own classes.
3125- Added new :doc:`File Helper <./helpers/file_helper>`:
3126 delete_files()
3127- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
3128 index_page()
3129- Added the ability to create your own :doc:`core
3130 libraries <general/creating_libraries>` and store them in your local
3131 application directory.
3132- Added an overwrite option to the :doc:`Upload
3133 class <./libraries/file_uploading>`, enabling files to be
3134 overwritten rather than having the file name appended.
3135- Added Javascript Calendar plugin.
3136- Added search feature to user guide. Note: This is done using Google,
3137 which at the time of this writing has not crawled all the pages of
3138 the docs.
3139- Updated the parser class so that it allows tag pars within other tag
3140 pairs.
3141- Fixed a bug in the DB "where" function.
3142- Fixed a bug that was preventing custom config files to be
3143 auto-loaded.
3144- Fixed a bug in the mysql class bind feature that prevented question
3145 marks in the replacement data.
3146- Fixed some bugs in the xss_clean function

3155 applications <general/managing_apps>` that share a common CodeIgniter
3156 backend.

3164 auto-load routine.
3165- Fixed a bug that can happen with PHP versions that do not support the
3166 E_STRICT constant
3167- Fixed a data type error in the form_radio function (form helper)
3168- Fixed a bug that was preventing the xss_clean function from being
3169 called from the validation class.
3170- Fixed the cookie related config names, which were incorrectly
3171 specified as $conf rather than $config
3172- Fixed a pagination problem in the scaffolding.
3173- Fixed a bug in the mysql class "where" function.
3174- Fixed a regex problem in some code that trimmed duplicate slashes.
3175- Fixed a bug in the br() function in the HTML helper
3176- Fixed a syntax mistake in the form_dropdown function in the Form
3177 Helper.
3178- Removed the "style" attributes form the form helpers.
