173Version 2.0.3
174=============
175
176Release Date: August 20, 2011
177
178- Security
179
180 - An improvement was made to the MySQL and MySQLi drivers to prevent
181 exposing a potential vector for SQL injection on sites using
182 multi-byte character sets in the database client connection.
183 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
184 *mysql_set_charset()* creates a situation where using multi-byte
185 character sets on these environments may potentially expose a SQL
186 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
187 character sets are unaffected on all environments.
188
189 If you are running or considering running a multi-byte character
190 set for your database connection, please pay close attention to
191 the server environment you are deploying on to ensure you are not
192 vulnerable.

233 library <libraries/loader>` to retrieve global vars set with
234 $this->load->view() and $this->load->vars().
235 - Changed $this->db->having() to insert quotes using escape() rather
236 than escape_str().
237

240
241- Added ENVIRONMENT to reserved constants. (Reactor #196)
242- Changed server check to ensure SCRIPT_NAME is defined. (Reactor #57)

259- Fixed a bug where not setting 'null' when adding fields in db_forge
260 for mysql and mysqli drivers would default to NULL instead of NOT
261 NULL as the docs suggest.
262- Fixed a bug where using $this->db->select_max(),
263 $this->db->select_min(), etc could throw notices. Thanks to w43l for
264 the patch.
265- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
266 whole is more reliable. This should get parameters in crontab
267 working.

Derek Jones8ede1a22011-10-05 13:34:52 -0500377Version 2.0.0
378=============
379
380Release Date: January 28, 2011
381Hg Tag: v2.0.0
382
383- General changes
384
385 - PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.
386 - Scaffolding, having been deprecated for a number of versions, has
387 been removed.
388 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
389 has been converted to a Helper and
390 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
391 calendar plugin was removed due to the ready availability of great
392 JavaScript calendars, particularly with jQuery.
393 - Added new special Library type:
394 :doc:`Drivers <./general/drivers>`.
395 - Added full query-string support. See the config file for details.
396 - Moved the application folder outside of the system folder.
397 - Moved system/cache and system/logs directories to the application
398 directory.
399 - Added routing overrides to the main index.php file, enabling the
400 normal routing to be overridden on a per "index" file basis.
401 - Added the ability to set config values (or override config values)
402 directly from data set in the main index.php file. This allows a
403 single application to be used with multiple front controllers,
404 each having its own config values.
405 - Added $config['directory_trigger'] to the config file so that a
406 controller sub-directory can be specified when running _GET
407 strings instead of URI segments.
408 - Added ability to set "Package" paths - specific paths where the
409 Loader and Config classes should try to look first for a requested
410 file. This allows distribution of sub-applications with their own
411 libraries, models, config files, etc. in a single "package"
412 directory. See the :doc:`Loader class <libraries/loader>`
413 documentation for more details.
414 - In-development code is now hosted at
415 `BitBucket <http://bitbucket.org/ellislab/codeigniter-reactor/>`_.
416 - Removed the deprecated Validation Class.
417 - Added CI\_ Prefix to all core classes.
418 - Package paths can now be set in application/config/autoload.php.
kenjis087a7a82011-10-20 20:08:47 +0900419 - :doc:`Upload library <libraries/file_uploading>` file_name can
Derek Jones8ede1a22011-10-05 13:34:52 -0500420 now be set without an extension, the extension will be taken from
421 the uploaded file instead of the given name.
422 - In :doc:`Database Forge <database/forge>` the name can be omitted
423 from $this->dbforge->modify_column()'s 2nd param if you aren't
424 changing the name.
425 - $config['base_url'] is now empty by default and will guess what
426 it should be.
427 - Enabled full Command Line Interface compatibility with
428 config['uri_protocol'] = 'CLI';.
429
430- Libraries
431
432 - Added a :doc:`Cache driver <libraries/caching>` with APC,

450 that one can specify the object to look for requested methods,
451 instead of assuming it is in the $CI superobject.
452 - Added "is_object" into the list of unit tests capable of being
453 run.
454 - Table library will generate an empty cell with a blank string, or
455 NULL value.

478 $this->zip->read_dir('/path/to/directory', FALSE) to remove the
479 preceding trail of empty folders when creating a Zip archive. This
480 example would contain a zip with "directory" and all of its
481 contents.
482 - Added ability in the Image Library to handle PNG transparency for
483 resize operations when using the GD lib.
484 - Modified the Session class to prevent use if no encryption key is
485 set in the config file.
486 - Added a new config item to the Session class
487 sess_expire_on_close to allow sessions to auto-expire when the

576
577 - Added an optional second parameter to show_404() to disable
578 logging.

901===========
902
903Release Date: October 23, 2008
904Hg Tag: 1.7.0
905
906- Libraries
907
908 - Added a new :doc:`Form Validation
909 Class <libraries/form_validation>`. It simplifies setting
910 rules and field names, supports arrays as field names, allows
911 groups of validation rules to be saved in a config file, and adds
912 some helper functions for use in view files. **Please note that
913 the old Validation class is now deprecated**. We will leave it in
914 the library folder for some time so that existing applications
915 that use it will not break, but you are encouraged to migrate to
916 the new version.
917 - Updated the :doc:`Sessions class <libraries/sessions>` so that
918 any custom data being saved gets stored to a database rather than
919 the session cookie (assuming you are using a database to store
920 session data), permitting much more data to be saved.
921 - Added the ability to store libraries in subdirectories within
922 either the main "libraries" or the local application "libraries"
923 folder. Please see the :doc:`Loader class <libraries/loader>` for
924 more info.
925 - Added the ability to assign library objects to your own variable
926 names when you use $this->load->library(). Please see the :doc:`Loader
927 class <libraries/loader>` for more info.
928 - Added controller class/method info to :doc:`Profiler
929 class <general/profiling>` and support for multiple database
930 connections.
931 - Improved the "auto typography" feature and moved it out of the
932 helper into its own :doc:`Typography
933 Class <libraries/typography>`.
934 - Improved performance and accuracy of xss_clean(), including
935 reduction of false positives on image/file tests.
936 - Improved :doc:`Parser class <./libraries/parser>` to allow
937 multiple calls to the parse() function. The output of each is
938 appended in the output.
939 - Added max_filename option to set a file name length limit in the
940 :doc:`File Upload Class <libraries/file_uploading>`.
941 - Added set_status_header() function to :doc:`Output
942 class <libraries/output>`.
943 - Modified :doc:`Pagination <libraries/pagination>` class to only
944 output the "First" link when the link for page one would not be
945 shown.
946 - Added support for mb_strlen in the :doc:`Form
947 Validation <libraries/form_validation>` class so that
948 multi-byte languages will calculate string lengths properly.
949
950- Database
951
952 - Improved Active Record class to allow full path column and table
953 names: hostname.database.table.column. Also improved the alias
954 handling.
955 - Improved how table and column names are escaped and prefixed. It
956 now honors full path names when adding prefixes and escaping.
957 - Added Active Record caching feature to "update" and "delete"
958 functions.
959 - Added removal of non-printing control characters in escape_str()
960 of DB drivers that do not have native PHP escaping mechanisms
961 (mssql, oci8, odbc), to avoid potential SQL errors, and possible
962 sources of SQL injection.
963 - Added port support to MySQL, MySQLi, and MS SQL database drivers.
964 - Added driver name variable in each DB driver, based on bug report
965 #4436.
966
967- Helpers
968
969 - Added several new "setting" functions to the :doc:`Form
970 helper <helpers/form_helper>` that allow POST data to be
971 retrieved and set into forms. These are intended to be used on
972 their own, or with the new :doc:`Form Validation
973 Class <libraries/form_validation>`.
974 - Added current_url() and uri_segments() to :doc:`URL
975 helper <helpers/url_helper>`.
976 - Altered auto_link() in the :doc:`URL
977 helper <helpers/url_helper>` so that email addresses with
978 "+" included will be linked.
979 - Added meta() function to :doc:`HTML
980 helper <helpers/html_helper>`.
981 - Improved accuracy of calculations in :doc:`Number
982 helper <helpers/number_helper>`.
983 - Removed added newlines ("\\n") from most form and html helper
984 functions.
985 - Tightened up validation in the :doc:`Date
986 helper <helpers/date_helper>` function human_to_unix(),
987 and eliminated the POSIX regex.
988 - Updated :doc:`Date helper <helpers/date_helper>` to match the
989 world's current time zones and offsets.
990 - Modified url_title() in the :doc:`URL
991 helper <helpers/url_helper>` to remove characters and digits
992 that are part of character entities, to allow dashes, underscores,
993 and periods regardless of the $separator, and to allow uppercase
994 characters.
995 - Added support for arbitrary attributes in anchor_popup() of the
996 :doc:`URL helper <helpers/url_helper>`.
997
998- Other Changes
999
1000 - Added :doc:`PHP Style Guide <./general/styleguide>` to docs.
1001 - Added sanitization in xss_clean() for a deprecated HTML tag that
1002 could be abused in user input in Internet Explorer.
1003 - Added a few openxml document mime types, and an additional mobile
1004 agent to mimes.php and user_agents.php respectively.
1005 - Added a file lock check during caching, before trying to write to
1006 the file.
1007 - Modified Cookie key cleaning to unset a few troublesome key names
1008 that can be present in certain environments, preventing CI from
1009 halting execution.
1010 - Changed the output of the profiler to use style attribute rather
1011 than clear, and added the id "codeigniter_profiler" to the
1012 container div.

1881=============
1882
1883Release Date: September 21, 2006
1884
1885- Added a new feature that passes URI segments directly to your
1886 function calls as parameters. See the
1887 :doc:`Controllers <general/controllers>` page for more info.
1888- Added support for a function named _output(), which when used in
1889 your controllers will received the final rendered output from the
1890 output class. More info in the :doc:`Controllers <general/controllers>`
1891 page.
1892- Added several new functions in the :doc:`URI
1893 Class <./libraries/uri>` to let you retrieve and manipulate URI
1894 segments that have been re-routed using the :doc:`URI
1895 Routing <general/routing>` feature. Previously, the URI class did not
1896 permit you to access any re-routed URI segments, but now it does.
1897- Added :doc:`$this->output->set_header() <./libraries/output>`
1898 function, which allows you to set server headers.
1899- Updated plugins, helpers, and language classes to allow your
1900 application folder to contain its own plugins, helpers, and language
1901 folders. Previously they were always treated as global for your
1902 entire installation. If your application folder contains any of these
1903 resources they will be used *instead* the global ones.
1904- Added :doc:`Inflector helper <./helpers/inflector_helper>`.
1905- Added element() function in the :doc:`array
1906 helper <./helpers/array_helper>`.
1907- Added RAND() to active record orderby() function.
1908- Added delete_cookie() and get_cookie() to :doc:`Cookie
1909 helper <./helpers/cookie_helper>`, even though the input class
1910 has a cookie fetching function.
1911- Added Oracle database driver (still undergoing testing so it might
1912 have some bugs).
1913- Added the ability to combine pseudo-variables and php variables in
1914 the template parser class.
1915- Added output compression option to the config file.
1916- Removed the is_numeric test from the db->escape() function.
1917- Fixed a MySQLi bug that was causing error messages not to contain
1918 proper error data.

1920 explicitly set alternative headers.
1921- Fixed a bug that was causing a PHP error when the Exceptions class
1922 was called within the get_config() function since it was causing
1923 problems.
1924- Fixed an oversight in the cookie helper in which the config file
1925 cookie settings were not being honored.
1926- Fixed an oversight in the upload class. An item mentioned in the 1.4
1927 changelog was missing.
1928- Added some code to allow email attachments to be reset when sending
1929 batches of email.
1930- Deprecated the application/scripts folder. It will continue to work
1931 for legacy users, but it is recommended that you create your own
1932 :doc:`libraries <./general/libraries>` or
1933 :doc:`models <./general/models>` instead. It was originally added
1934 before CI had user libraries or models, but it's not needed anymore.
1935- Deprecated the $autoload['core'] item from the autoload.php file.
1936 Instead, please now use: $autoload['libraries']
1937- Deprecated the following database functions:
1938 $this->db->smart_escape_str() and $this->db->fields().

1946 into and modify the inner workings of the framework without hacking
1947 the core files.
1948- Added the ability to organize controller files :doc:`into
1949 sub-folders <general/controllers>`. Kudos to Marco for
1950 `suggesting <http://codeigniter.com/forums/viewthread/627/>`_ this
1951 (and the next two) feature.
kenjis087a7a82011-10-20 20:08:47 +09001952- Added regular expressions support for :doc:`routing

1967- Moved the MIME type array out of the Upload class and into its own
1968 file in the applications/config/ folder.
1969- Updated the Upload class to allow the upload field name to be set
1970 when calling :doc:`do_upload() <./libraries/file_uploading>`.
1971- Updated the :doc:`Config Library <./libraries/config>` to be able to
1972 load config files silently, and to be able to assign config files to
1973 their own index (to avoid collisions if you use multiple config
1974 files).
1975- Updated the URI Protocol code to allow more options so that URLs will
1976 work more reliably in different environments.
1977- Updated the form_open() helper to allow the GET method to be used.
1978- Updated the MySQLi execute() function with some code to help prevent
1979 lost connection errors.
1980- Updated the SQLite Driver to check for object support before
1981 attempting to return results as objects. If unsupported it returns an

1992- Renamed display() to _display() in the Output class to make it clear
1993 that it's a private function.
1994- Deprecated the hash() function due to a naming conflict with a native
1995 PHP function with the same name. Please use dohash() instead.
1996- Fixed an bug that was preventing the input class from unsetting GET

2034
2035- Models do **not** connect automatically to the database as of this
2036 version. :doc:`More info here <./general/models>`.
2037- Updated the Sessions class to utilize the active record class when
2038 running session related queries. Previously the queries assumed MySQL

2059=============
2060
2061Release Date: April 17, 2006
2062
2063- Changed the behavior of the validation class such that if a
2064 "required" rule is NOT explicitly stated for a field then all other
2065 tests get ignored.
2066- Fixed a bug in the Controller class that was causing it to look in
2067 the local "init" folder instead of the main system one.
2068- Fixed a bug in the init_pagination file. The $config item was not

2080- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
2081- Added the ability to pass objects to the **insert()** and
2082 **update()** database functions. This feature enables you to (among
2083 other things) use your :doc:`Model class <./general/models>`
2084 variables to run queries with. See the Models page for details.
2085- Added the ability to pass objects to the :doc:`view loading
2086 function <./general/views>`: $this->load->view('my_view',
2087 $object);
2088- Added getwhere function to :doc:`Active Record
2089 class <./database/active_record>`.
2090- Added count_all function to :doc:`Active Record
2091 class <./database/active_record>`.
2092- Added language file for scaffolding and fixed a scaffolding bug that
2093 occurs when there are no rows in the specified table.
2094- Added :doc:`$this->db->last_query() <./database/queries>`, which
2095 allows you to view your last query that was run.
2096- Added a new mime type to the upload class for better compatibility.
2097- Changed how cache files are read to prevent PHP errors if the cache
2098 file contains an XML tag, which PHP wants to interpret as a short
2099 tag.
2100- Fixed a bug in a couple of the active record functions (where and
2101 orderby).
2102- Fixed a bug in the image library when realpath() returns false.

2107
2108Version 1.3
2109===========
2110
2111Release Date: April 3, 2006
2112
2113- Added support for :doc:`Models <general/models>`.
2114- Redesigned the database libraries to support additional RDBMs
2115 (Postgres, MySQLi, etc.).
2116- Redesigned the :doc:`Active Record class <./database/active_record>`
2117 to enable more varied types of queries with simpler syntax, and
2118 advanced features like JOINs.
2119- Added a feature to the database class that lets you run :doc:`custom
2120 function calls <./database/call_function>`.
2121- Added support for :doc:`private functions <general/controllers>` in your
2122 controllers. Any controller function name that starts with an
2123 underscore will not be served by a URI request.
2124- Added the ability to pass your own initialization parameters to your
2125 :doc:`custom core libraries <general/creating_libraries>` when using
2126 $this->load->library()
2127- Added support for running standard :doc:`query string URLs <general/urls>`.
2128 These can be optionally enabled in your config file.
2129- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
2130 appended to your URLs. For example, you could add .html to your URLs,
2131 making them appear static. This feature is enabled in your config
2132 file.
2133- Added a new error template for use with native PHP errors.
2134- Added "alternator" function in the :doc:`string
2135 helpers <./helpers/string_helper>`.
2136- Removed slashing from the input class. After much debate we decided
2137 to kill this feature.
2138- Change the commenting style in the scripts to the PEAR standard so
2139 that IDEs and tools like phpDocumenter can harvest the comments.
2140- Added better class and function name-spacing to avoid collisions with
2141 user developed classes. All CodeIgniter classes are now prefixed with
2142 CI\_ and all controller methods are prefixed with _ci to avoid
2143 controller collisions. A list of reserved function names can be
2144 :doc:`found here <general/controllers>`.
2145- Redesigned how the "CI" super object is referenced, depending on
2146 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2147 way to manage objects that utilizes a bit less resources.
2148- Deprecated: $this->db->use_table() has been deprecated. Please read
2149 the :doc:`Active Record <./database/active_record>` page for
2150 information.
2151- Deprecated: $this->db->smart_escape_str() has been deprecated.
2152 Please use this instead: $this->db->escape()
2153- Fixed a bug in the exception handler which was preventing some PHP
2154 errors from showing up.
2155- Fixed a typo in the URI class. $this->total_segment() should be
2156 plural: $this->total_segments()
2157- Fixed some typos in the default calendar template
2158- Fixed some typos in the user guide
2159

2163Release Date: March 21, 2006
2164
2165- Redesigned some internal aspects of the framework to resolve scoping
2166 problems that surfaced during the beta tests. The problem was most
2167 notable when instantiating classes in your constructors, particularly
2168 if those classes in turn did work in their constructors.
2169- Added a global function named
2170 :doc:`get_instance() <general/ancillary_classes>` allowing the main
2171 CodeIgniter object to be accessible throughout your own classes.
2172- Added new :doc:`File Helper <./helpers/file_helper>`:
2173 delete_files()
2174- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2175 index_page()
2176- Added the ability to create your own :doc:`core
2177 libraries <general/creating_libraries>` and store them in your local
2178 application directory.
2179- Added an overwrite option to the :doc:`Upload
2180 class <./libraries/file_uploading>`, enabling files to be
2181 overwritten rather than having the file name appended.
2182- Added Javascript Calendar plugin.
2183- Added search feature to user guide. Note: This is done using Google,
2184 which at the time of this writing has not crawled all the pages of
2185 the docs.
2186- Updated the parser class so that it allows tag pars within other tag
2187 pairs.
2188- Fixed a bug in the DB "where" function.
2189- Fixed a bug that was preventing custom config files to be
