197Version 2.0.3
198=============
199
200Release Date: August 20, 2011
201
202- Security
203
204 - An improvement was made to the MySQL and MySQLi drivers to prevent
205 exposing a potential vector for SQL injection on sites using
206 multi-byte character sets in the database client connection.
207 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
208 *mysql_set_charset()* creates a situation where using multi-byte
209 character sets on these environments may potentially expose a SQL
210 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
211 character sets are unaffected on all environments.
212
213 If you are running or considering running a multi-byte character
214 set for your database connection, please pay close attention to
215 the server environment you are deploying on to ensure you are not
216 vulnerable.

232 - Added CSRF protection URI whitelisting.
Timothy Warren01b56bc2011-10-10 10:45:45 -0400233 - Fixed a bug where :doc:`Email library <libraries/email>`
Derek Jones8ede1a22011-10-05 13:34:52 -0500234 attachments with a "." in the name would using invalid MIME-types.
Derek Jones8ede1a22011-10-05 13:34:52 -0500235

240 - form_open() now only adds a hidden (Cross-site Reference Forgery)
241 protection field when the form's action is internal and is set to

244 helper <helpers/inflector_helper>` to support considerably
245 more words.

257 library <libraries/loader>` to retrieve global vars set with
258 $this->load->view() and $this->load->vars().
259 - Changed $this->db->having() to insert quotes using escape() rather
260 than escape_str().
261
262Bug fixes for 2.0.3
263-------------------
264
265- Added ENVIRONMENT to reserved constants. (Reactor #196)
266- Changed server check to ensure SCRIPT_NAME is defined. (Reactor #57)

283- Fixed a bug where not setting 'null' when adding fields in db_forge
284 for mysql and mysqli drivers would default to NULL instead of NOT
285 NULL as the docs suggest.
286- Fixed a bug where using $this->db->select_max(),
287 $this->db->select_min(), etc could throw notices. Thanks to w43l for
288 the patch.
289- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
290 whole is more reliable. This should get parameters in crontab
291 working.

404Release Date: January 28, 2011
405Hg Tag: v2.0.0
406
407- General changes
408
409 - PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.
410 - Scaffolding, having been deprecated for a number of versions, has
411 been removed.
412 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
413 has been converted to a Helper and
414 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
415 calendar plugin was removed due to the ready availability of great
416 JavaScript calendars, particularly with jQuery.
417 - Added new special Library type:
418 :doc:`Drivers <./general/drivers>`.
419 - Added full query-string support. See the config file for details.
420 - Moved the application folder outside of the system folder.
421 - Moved system/cache and system/logs directories to the application
422 directory.
423 - Added routing overrides to the main index.php file, enabling the
424 normal routing to be overridden on a per "index" file basis.
425 - Added the ability to set config values (or override config values)
426 directly from data set in the main index.php file. This allows a
427 single application to be used with multiple front controllers,
428 each having its own config values.
429 - Added $config['directory_trigger'] to the config file so that a
430 controller sub-directory can be specified when running _GET
431 strings instead of URI segments.
432 - Added ability to set "Package" paths - specific paths where the
433 Loader and Config classes should try to look first for a requested
434 file. This allows distribution of sub-applications with their own
435 libraries, models, config files, etc. in a single "package"
436 directory. See the :doc:`Loader class <libraries/loader>`
437 documentation for more details.
438 - In-development code is now hosted at
439 `BitBucket <http://bitbucket.org/ellislab/codeigniter-reactor/>`_.
440 - Removed the deprecated Validation Class.
441 - Added CI\_ Prefix to all core classes.
442 - Package paths can now be set in application/config/autoload.php.
kenjis087a7a82011-10-20 20:08:47 +0900443 - :doc:`Upload library <libraries/file_uploading>` file_name can
Derek Jones8ede1a22011-10-05 13:34:52 -0500444 now be set without an extension, the extension will be taken from
445 the uploaded file instead of the given name.
446 - In :doc:`Database Forge <database/forge>` the name can be omitted
447 from $this->dbforge->modify_column()'s 2nd param if you aren't
448 changing the name.
449 - $config['base_url'] is now empty by default and will guess what
450 it should be.
451 - Enabled full Command Line Interface compatibility with
452 config['uri_protocol'] = 'CLI';.
453
454- Libraries
455
456 - Added a :doc:`Cache driver <libraries/caching>` with APC,

461 page links by setting their values to FALSE in the :doc:`Pagination
462 library <./libraries/pagination>`.
463 - Added :doc:`Security library <./libraries/security>`, which now
464 contains the xss_clean function, filename_security function and

473 - Added an 'object' config variable to the XML-RPC Server library so
474 that one can specify the object to look for requested methods,
475 instead of assuming it is in the $CI superobject.
476 - Added "is_object" into the list of unit tests capable of being
477 run.
478 - Table library will generate an empty cell with a blank string, or
479 NULL value.
480 - Added ability to set tag attributes for individual cells in the
481 Table library
482 - Added a parse_string() method to the :doc:`Parser
483 Class <libraries/parser>`.

493 control over the use of the Security library's xss_clean()
494 method.

500 type value to standardize input in Upload library.
501 - Added a second parameter (boolean) to
502 $this->zip->read_dir('/path/to/directory', FALSE) to remove the
503 preceding trail of empty folders when creating a Zip archive. This
504 example would contain a zip with "directory" and all of its
505 contents.
506 - Added ability in the Image Library to handle PNG transparency for
507 resize operations when using the GD lib.
508 - Modified the Session class to prevent use if no encryption key is
509 set in the config file.
510 - Added a new config item to the Session class
511 sess_expire_on_close to allow sessions to auto-expire when the

930- Libraries
931
932 - Added a new :doc:`Form Validation
933 Class <libraries/form_validation>`. It simplifies setting
934 rules and field names, supports arrays as field names, allows
935 groups of validation rules to be saved in a config file, and adds
936 some helper functions for use in view files. **Please note that
937 the old Validation class is now deprecated**. We will leave it in
938 the library folder for some time so that existing applications
939 that use it will not break, but you are encouraged to migrate to
940 the new version.
941 - Updated the :doc:`Sessions class <libraries/sessions>` so that
942 any custom data being saved gets stored to a database rather than
943 the session cookie (assuming you are using a database to store
944 session data), permitting much more data to be saved.
945 - Added the ability to store libraries in subdirectories within
946 either the main "libraries" or the local application "libraries"
947 folder. Please see the :doc:`Loader class <libraries/loader>` for
948 more info.

950 names when you use $this->load->library(). Please see the :doc:`Loader
951 class <libraries/loader>` for more info.

953 class <general/profiling>` and support for multiple database
954 connections.
955 - Improved the "auto typography" feature and moved it out of the
956 helper into its own :doc:`Typography
957 Class <libraries/typography>`.
958 - Improved performance and accuracy of xss_clean(), including
959 reduction of false positives on image/file tests.
960 - Improved :doc:`Parser class <./libraries/parser>` to allow
961 multiple calls to the parse() function. The output of each is
962 appended in the output.
963 - Added max_filename option to set a file name length limit in the
964 :doc:`File Upload Class <libraries/file_uploading>`.
965 - Added set_status_header() function to :doc:`Output
966 class <libraries/output>`.
967 - Modified :doc:`Pagination <libraries/pagination>` class to only
968 output the "First" link when the link for page one would not be
969 shown.
970 - Added support for mb_strlen in the :doc:`Form
971 Validation <libraries/form_validation>` class so that
972 multi-byte languages will calculate string lengths properly.
973
974- Database
975
976 - Improved Active Record class to allow full path column and table
977 names: hostname.database.table.column. Also improved the alias
978 handling.
979 - Improved how table and column names are escaped and prefixed. It
980 now honors full path names when adding prefixes and escaping.
981 - Added Active Record caching feature to "update" and "delete"
982 functions.
983 - Added removal of non-printing control characters in escape_str()
984 of DB drivers that do not have native PHP escaping mechanisms
985 (mssql, oci8, odbc), to avoid potential SQL errors, and possible
986 sources of SQL injection.
987 - Added port support to MySQL, MySQLi, and MS SQL database drivers.
988 - Added driver name variable in each DB driver, based on bug report
989 #4436.
990
991- Helpers
992
993 - Added several new "setting" functions to the :doc:`Form
994 helper <helpers/form_helper>` that allow POST data to be
995 retrieved and set into forms. These are intended to be used on
996 their own, or with the new :doc:`Form Validation
997 Class <libraries/form_validation>`.
998 - Added current_url() and uri_segments() to :doc:`URL
999 helper <helpers/url_helper>`.
1000 - Altered auto_link() in the :doc:`URL
1001 helper <helpers/url_helper>` so that email addresses with
1002 "+" included will be linked.
1003 - Added meta() function to :doc:`HTML
1004 helper <helpers/html_helper>`.
1005 - Improved accuracy of calculations in :doc:`Number
1006 helper <helpers/number_helper>`.

1013 world's current time zones and offsets.
1014 - Modified url_title() in the :doc:`URL

1016 that are part of character entities, to allow dashes, underscores,
1017 and periods regardless of the $separator, and to allow uppercase
1018 characters.
1019 - Added support for arbitrary attributes in anchor_popup() of the
1020 :doc:`URL helper <helpers/url_helper>`.
1021
1022- Other Changes

1025 - Added sanitization in xss_clean() for a deprecated HTML tag that
1026 could be abused in user input in Internet Explorer.
1027 - Added a few openxml document mime types, and an additional mobile
1028 agent to mimes.php and user_agents.php respectively.
1029 - Added a file lock check during caching, before trying to write to
1030 the file.
1031 - Modified Cookie key cleaning to unset a few troublesome key names
1032 that can be present in certain environments, preventing CI from
1033 halting execution.
1034 - Changed the output of the profiler to use style attribute rather
1035 than clear, and added the id "codeigniter_profiler" to the
1036 container div.

1905=============
1906
1907Release Date: September 21, 2006
1908
1909- Added a new feature that passes URI segments directly to your
1910 function calls as parameters. See the
1911 :doc:`Controllers <general/controllers>` page for more info.
1912- Added support for a function named _output(), which when used in
1913 your controllers will received the final rendered output from the
1914 output class. More info in the :doc:`Controllers <general/controllers>`
1915 page.
1916- Added several new functions in the :doc:`URI
1917 Class <./libraries/uri>` to let you retrieve and manipulate URI
1918 segments that have been re-routed using the :doc:`URI
1919 Routing <general/routing>` feature. Previously, the URI class did not
1920 permit you to access any re-routed URI segments, but now it does.
1921- Added :doc:`$this->output->set_header() <./libraries/output>`
1922 function, which allows you to set server headers.
1923- Updated plugins, helpers, and language classes to allow your
1924 application folder to contain its own plugins, helpers, and language
1925 folders. Previously they were always treated as global for your
1926 entire installation. If your application folder contains any of these
1927 resources they will be used *instead* the global ones.
1928- Added :doc:`Inflector helper <./helpers/inflector_helper>`.
1929- Added element() function in the :doc:`array
1930 helper <./helpers/array_helper>`.
1931- Added RAND() to active record orderby() function.
1932- Added delete_cookie() and get_cookie() to :doc:`Cookie
1933 helper <./helpers/cookie_helper>`, even though the input class
1934 has a cookie fetching function.
1935- Added Oracle database driver (still undergoing testing so it might
1936 have some bugs).
1937- Added the ability to combine pseudo-variables and php variables in
1938 the template parser class.
1939- Added output compression option to the config file.
1940- Removed the is_numeric test from the db->escape() function.
1941- Fixed a MySQLi bug that was causing error messages not to contain
1942 proper error data.
1943- Fixed a bug in the email class which was causing it to ignore
1944 explicitly set alternative headers.
1945- Fixed a bug that was causing a PHP error when the Exceptions class
1946 was called within the get_config() function since it was causing
1947 problems.
1948- Fixed an oversight in the cookie helper in which the config file
1949 cookie settings were not being honored.
1950- Fixed an oversight in the upload class. An item mentioned in the 1.4
1951 changelog was missing.
1952- Added some code to allow email attachments to be reset when sending
1953 batches of email.
1954- Deprecated the application/scripts folder. It will continue to work
1955 for legacy users, but it is recommended that you create your own
1956 :doc:`libraries <./general/libraries>` or
1957 :doc:`models <./general/models>` instead. It was originally added
1958 before CI had user libraries or models, but it's not needed anymore.
1959- Deprecated the $autoload['core'] item from the autoload.php file.
1960 Instead, please now use: $autoload['libraries']
1961- Deprecated the following database functions:
1962 $this->db->smart_escape_str() and $this->db->fields().

1970 into and modify the inner workings of the framework without hacking
1971 the core files.
1972- Added the ability to organize controller files :doc:`into
1973 sub-folders <general/controllers>`. Kudos to Marco for
1974 `suggesting <http://codeigniter.com/forums/viewthread/627/>`_ this
1975 (and the next two) feature.
kenjis087a7a82011-10-20 20:08:47 +09001976- Added regular expressions support for :doc:`routing

1986 helper.
1987- Added support for changing the port number in the :doc:`Postgres
1988 driver <./database/configuration>`.
1989- Moved the list of "allowed URI characters" out of the Router class
1990 and into the config file.
1991- Moved the MIME type array out of the Upload class and into its own
1992 file in the applications/config/ folder.
1993- Updated the Upload class to allow the upload field name to be set
1994 when calling :doc:`do_upload() <./libraries/file_uploading>`.
1995- Updated the :doc:`Config Library <./libraries/config>` to be able to
1996 load config files silently, and to be able to assign config files to
1997 their own index (to avoid collisions if you use multiple config
1998 files).
1999- Updated the URI Protocol code to allow more options so that URLs will
2000 work more reliably in different environments.
2001- Updated the form_open() helper to allow the GET method to be used.
2002- Updated the MySQLi execute() function with some code to help prevent
2003 lost connection errors.
2004- Updated the SQLite Driver to check for object support before
2005 attempting to return results as objects. If unsupported it returns an

2016- Renamed display() to _display() in the Output class to make it clear
2017 that it's a private function.
2018- Deprecated the hash() function due to a naming conflict with a native
2019 PHP function with the same name. Please use dohash() instead.
2020- Fixed an bug that was preventing the input class from unsetting GET

2058
2059- Models do **not** connect automatically to the database as of this
2060 version. :doc:`More info here <./general/models>`.
2061- Updated the Sessions class to utilize the active record class when
2062 running session related queries. Previously the queries assumed MySQL

2065 arguments, allowing multiple calls.
2066- Fixed a bug in the active record "having" function.
2067- Fixed a problem in the validation class which was making checkboxes
2068 be ignored when required.

2072 some versions of html_entity_decode.
2073- Fixed a validation bug that was preventing rules from being set twice
2074 in one controller.

2082Version 1.3.2
2083=============
2084
2085Release Date: April 17, 2006
2086
2087- Changed the behavior of the validation class such that if a
2088 "required" rule is NOT explicitly stated for a field then all other
2089 tests get ignored.
2090- Fixed a bug in the Controller class that was causing it to look in
2091 the local "init" folder instead of the main system one.
2092- Fixed a bug in the init_pagination file. The $config item was not
2093 being set correctly.

2104- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
2105- Added the ability to pass objects to the **insert()** and
2106 **update()** database functions. This feature enables you to (among
2107 other things) use your :doc:`Model class <./general/models>`
2108 variables to run queries with. See the Models page for details.
2109- Added the ability to pass objects to the :doc:`view loading
2110 function <./general/views>`: $this->load->view('my_view',
2111 $object);
2112- Added getwhere function to :doc:`Active Record
2113 class <./database/active_record>`.
2114- Added count_all function to :doc:`Active Record
2115 class <./database/active_record>`.
2116- Added language file for scaffolding and fixed a scaffolding bug that
2117 occurs when there are no rows in the specified table.
2118- Added :doc:`$this->db->last_query() <./database/queries>`, which
2119 allows you to view your last query that was run.
2120- Added a new mime type to the upload class for better compatibility.
2121- Changed how cache files are read to prevent PHP errors if the cache
2122 file contains an XML tag, which PHP wants to interpret as a short
2123 tag.
2124- Fixed a bug in a couple of the active record functions (where and
2125 orderby).
2126- Fixed a bug in the image library when realpath() returns false.

2131
2132Version 1.3
2133===========
2134
2135Release Date: April 3, 2006
2136
2137- Added support for :doc:`Models <general/models>`.
2138- Redesigned the database libraries to support additional RDBMs
2139 (Postgres, MySQLi, etc.).
2140- Redesigned the :doc:`Active Record class <./database/active_record>`
2141 to enable more varied types of queries with simpler syntax, and
2142 advanced features like JOINs.
2143- Added a feature to the database class that lets you run :doc:`custom
2144 function calls <./database/call_function>`.
2145- Added support for :doc:`private functions <general/controllers>` in your
2146 controllers. Any controller function name that starts with an
2147 underscore will not be served by a URI request.
2148- Added the ability to pass your own initialization parameters to your
2149 :doc:`custom core libraries <general/creating_libraries>` when using
2150 $this->load->library()
2151- Added support for running standard :doc:`query string URLs <general/urls>`.
2152 These can be optionally enabled in your config file.
2153- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
2154 appended to your URLs. For example, you could add .html to your URLs,
2155 making them appear static. This feature is enabled in your config
2156 file.
2157- Added a new error template for use with native PHP errors.
2158- Added "alternator" function in the :doc:`string
2159 helpers <./helpers/string_helper>`.
2160- Removed slashing from the input class. After much debate we decided
2161 to kill this feature.
2162- Change the commenting style in the scripts to the PEAR standard so
2163 that IDEs and tools like phpDocumenter can harvest the comments.
2164- Added better class and function name-spacing to avoid collisions with
2165 user developed classes. All CodeIgniter classes are now prefixed with
2166 CI\_ and all controller methods are prefixed with _ci to avoid
2167 controller collisions. A list of reserved function names can be
2168 :doc:`found here <general/controllers>`.
2169- Redesigned how the "CI" super object is referenced, depending on
2170 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2171 way to manage objects that utilizes a bit less resources.
2172- Deprecated: $this->db->use_table() has been deprecated. Please read
2173 the :doc:`Active Record <./database/active_record>` page for
2174 information.
2175- Deprecated: $this->db->smart_escape_str() has been deprecated.
2176 Please use this instead: $this->db->escape()
2177- Fixed a bug in the exception handler which was preventing some PHP
2178 errors from showing up.
2179- Fixed a typo in the URI class. $this->total_segment() should be
2180 plural: $this->total_segments()
2181- Fixed some typos in the default calendar template
2182- Fixed some typos in the user guide
2183
2184Version 1.2
2185===========
2186
2187Release Date: March 21, 2006
2188
2189- Redesigned some internal aspects of the framework to resolve scoping
2190 problems that surfaced during the beta tests. The problem was most
2191 notable when instantiating classes in your constructors, particularly
2192 if those classes in turn did work in their constructors.
2193- Added a global function named
2194 :doc:`get_instance() <general/ancillary_classes>` allowing the main
2195 CodeIgniter object to be accessible throughout your own classes.
2196- Added new :doc:`File Helper <./helpers/file_helper>`:
2197 delete_files()
2198- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2199 index_page()
2200- Added the ability to create your own :doc:`core
2201 libraries <general/creating_libraries>` and store them in your local
2202 application directory.
2203- Added an overwrite option to the :doc:`Upload
2204 class <./libraries/file_uploading>`, enabling files to be
2205 overwritten rather than having the file name appended.
2206- Added Javascript Calendar plugin.
2207- Added search feature to user guide. Note: This is done using Google,
2208 which at the time of this writing has not crawled all the pages of
2209 the docs.
2210- Updated the parser class so that it allows tag pars within other tag
2211 pairs.
2212- Fixed a bug in the DB "where" function.
2213- Fixed a bug that was preventing custom config files to be
2214 auto-loaded.
2215- Fixed a bug in the mysql class bind feature that prevented question
2216 marks in the replacement data.
2217- Fixed some bugs in the xss_clean function

2221
2222Release Date: March 10, 2006

2224- Added a :doc:`Calendaring class <./libraries/calendar>`.
2225- Added support for running :doc:`multiple
2226 applications <general/managing_apps>` that share a common CodeIgniter
