299Version 2.0.3
300=============
301
302Release Date: August 20, 2011
303
304- Security
305
306 - An improvement was made to the MySQL and MySQLi drivers to prevent
307 exposing a potential vector for SQL injection on sites using
308 multi-byte character sets in the database client connection.
309 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
310 *mysql_set_charset()* creates a situation where using multi-byte
311 character sets on these environments may potentially expose a SQL
312 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
313 character sets are unaffected on all environments.
314
315 If you are running or considering running a multi-byte character
316 set for your database connection, please pay close attention to
317 the server environment you are deploying on to ensure you are not
318 vulnerable.

Timothy Warren01b56bc2011-10-10 10:45:45 -0400335 - Fixed a bug where :doc:`Email library <libraries/email>`
Derek Jones8ede1a22011-10-05 13:34:52 -0500336 attachments with a "." in the name would using invalid MIME-types.
Derek Jones8ede1a22011-10-05 13:34:52 -0500337

343 protection field when the form's action is internal and is set to
344 the post method. (Reactor #165)

346 helper <helpers/inflector_helper>` to support considerably
347 more words.

359 library <libraries/loader>` to retrieve global vars set with
360 $this->load->view() and $this->load->vars().

362 than escape_str().
363

366
367- Added ENVIRONMENT to reserved constants. (Reactor #196)
368- Changed server check to ensure SCRIPT_NAME is defined. (Reactor #57)

384 of all items in the cart instead of your total count.
385- Fixed a bug where not setting 'null' when adding fields in db_forge
386 for mysql and mysqli drivers would default to NULL instead of NOT
387 NULL as the docs suggest.
388- Fixed a bug where using $this->db->select_max(),
389 $this->db->select_min(), etc could throw notices. Thanks to w43l for
390 the patch.
391- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
392 whole is more reliable. This should get parameters in crontab
393 working.

511 - PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.
512 - Scaffolding, having been deprecated for a number of versions, has
513 been removed.
514 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
515 has been converted to a Helper and
516 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
517 calendar plugin was removed due to the ready availability of great
518 JavaScript calendars, particularly with jQuery.
519 - Added new special Library type:
520 :doc:`Drivers <./general/drivers>`.
521 - Added full query-string support. See the config file for details.
522 - Moved the application folder outside of the system folder.
523 - Moved system/cache and system/logs directories to the application
524 directory.
525 - Added routing overrides to the main index.php file, enabling the
526 normal routing to be overridden on a per "index" file basis.
527 - Added the ability to set config values (or override config values)
528 directly from data set in the main index.php file. This allows a
529 single application to be used with multiple front controllers,
530 each having its own config values.
531 - Added $config['directory_trigger'] to the config file so that a
532 controller sub-directory can be specified when running _GET
533 strings instead of URI segments.
534 - Added ability to set "Package" paths - specific paths where the
535 Loader and Config classes should try to look first for a requested
536 file. This allows distribution of sub-applications with their own
537 libraries, models, config files, etc. in a single "package"
538 directory. See the :doc:`Loader class <libraries/loader>`
539 documentation for more details.
540 - In-development code is now hosted at

Derek Jones8ede1a22011-10-05 13:34:52 -0500546 now be set without an extension, the extension will be taken from
547 the uploaded file instead of the given name.
548 - In :doc:`Database Forge <database/forge>` the name can be omitted
549 from $this->dbforge->modify_column()'s 2nd param if you aren't
550 changing the name.
551 - $config['base_url'] is now empty by default and will guess what

1032- Libraries
1033
1034 - Added a new :doc:`Form Validation
1035 Class <libraries/form_validation>`. It simplifies setting
1036 rules and field names, supports arrays as field names, allows
1037 groups of validation rules to be saved in a config file, and adds
1038 some helper functions for use in view files. **Please note that
1039 the old Validation class is now deprecated**. We will leave it in
1040 the library folder for some time so that existing applications
1041 that use it will not break, but you are encouraged to migrate to
1042 the new version.
1043 - Updated the :doc:`Sessions class <libraries/sessions>` so that
1044 any custom data being saved gets stored to a database rather than
1045 the session cookie (assuming you are using a database to store
1046 session data), permitting much more data to be saved.
1047 - Added the ability to store libraries in subdirectories within
1048 either the main "libraries" or the local application "libraries"

2006Version 1.4.1
2007=============
2008
2009Release Date: September 21, 2006
2010
2011- Added a new feature that passes URI segments directly to your
2012 function calls as parameters. See the
2013 :doc:`Controllers <general/controllers>` page for more info.
2014- Added support for a function named _output(), which when used in
2015 your controllers will received the final rendered output from the
2016 output class. More info in the :doc:`Controllers <general/controllers>`
2017 page.
2018- Added several new functions in the :doc:`URI
2019 Class <./libraries/uri>` to let you retrieve and manipulate URI
2020 segments that have been re-routed using the :doc:`URI
2021 Routing <general/routing>` feature. Previously, the URI class did not
2022 permit you to access any re-routed URI segments, but now it does.
2023- Added :doc:`$this->output->set_header() <./libraries/output>`
2024 function, which allows you to set server headers.
2025- Updated plugins, helpers, and language classes to allow your
2026 application folder to contain its own plugins, helpers, and language
2027 folders. Previously they were always treated as global for your
2028 entire installation. If your application folder contains any of these
2029 resources they will be used *instead* the global ones.
2030- Added :doc:`Inflector helper <./helpers/inflector_helper>`.
2031- Added element() function in the :doc:`array
2032 helper <./helpers/array_helper>`.
2033- Added RAND() to active record orderby() function.
2034- Added delete_cookie() and get_cookie() to :doc:`Cookie
2035 helper <./helpers/cookie_helper>`, even though the input class
2036 has a cookie fetching function.
2037- Added Oracle database driver (still undergoing testing so it might
2038 have some bugs).
2039- Added the ability to combine pseudo-variables and php variables in
2040 the template parser class.
2041- Added output compression option to the config file.
2042- Removed the is_numeric test from the db->escape() function.
2043- Fixed a MySQLi bug that was causing error messages not to contain
2044 proper error data.
2045- Fixed a bug in the email class which was causing it to ignore
2046 explicitly set alternative headers.
2047- Fixed a bug that was causing a PHP error when the Exceptions class
2048 was called within the get_config() function since it was causing
2049 problems.
2050- Fixed an oversight in the cookie helper in which the config file
2051 cookie settings were not being honored.
2052- Fixed an oversight in the upload class. An item mentioned in the 1.4
2053 changelog was missing.
2054- Added some code to allow email attachments to be reset when sending
2055 batches of email.
2056- Deprecated the application/scripts folder. It will continue to work
2057 for legacy users, but it is recommended that you create your own
2058 :doc:`libraries <./general/libraries>` or
2059 :doc:`models <./general/models>` instead. It was originally added
2060 before CI had user libraries or models, but it's not needed anymore.
2061- Deprecated the $autoload['core'] item from the autoload.php file.
2062 Instead, please now use: $autoload['libraries']
2063- Deprecated the following database functions:
2064 $this->db->smart_escape_str() and $this->db->fields().

2072 into and modify the inner workings of the framework without hacking
2073 the core files.
2074- Added the ability to organize controller files :doc:`into
2075 sub-folders <general/controllers>`. Kudos to Marco for
2076 `suggesting <http://codeigniter.com/forums/viewthread/627/>`_ this
2077 (and the next two) feature.
kenjis087a7a82011-10-20 20:08:47 +09002078- Added regular expressions support for :doc:`routing

2094 file in the applications/config/ folder.
2095- Updated the Upload class to allow the upload field name to be set
2096 when calling :doc:`do_upload() <./libraries/file_uploading>`.
2097- Updated the :doc:`Config Library <./libraries/config>` to be able to
2098 load config files silently, and to be able to assign config files to
2099 their own index (to avoid collisions if you use multiple config
2100 files).
2101- Updated the URI Protocol code to allow more options so that URLs will
2102 work more reliably in different environments.
2103- Updated the form_open() helper to allow the GET method to be used.
2104- Updated the MySQLi execute() function with some code to help prevent
2105 lost connection errors.
2106- Updated the SQLite Driver to check for object support before
2107 attempting to return results as objects. If unsupported it returns an

2160
2161- Models do **not** connect automatically to the database as of this
2162 version. :doc:`More info here <./general/models>`.
2163- Updated the Sessions class to utilize the active record class when
2164 running session related queries. Previously the queries assumed MySQL

2185=============
2186
2187Release Date: April 17, 2006
2188
2189- Changed the behavior of the validation class such that if a
2190 "required" rule is NOT explicitly stated for a field then all other
2191 tests get ignored.
2192- Fixed a bug in the Controller class that was causing it to look in
2193 the local "init" folder instead of the main system one.
2194- Fixed a bug in the init_pagination file. The $config item was not

2206- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
2207- Added the ability to pass objects to the **insert()** and
2208 **update()** database functions. This feature enables you to (among
2209 other things) use your :doc:`Model class <./general/models>`
2210 variables to run queries with. See the Models page for details.
2211- Added the ability to pass objects to the :doc:`view loading
2212 function <./general/views>`: $this->load->view('my_view',
2213 $object);
2214- Added getwhere function to :doc:`Active Record
2215 class <./database/active_record>`.
2216- Added count_all function to :doc:`Active Record
2217 class <./database/active_record>`.
2218- Added language file for scaffolding and fixed a scaffolding bug that
2219 occurs when there are no rows in the specified table.
2220- Added :doc:`$this->db->last_query() <./database/queries>`, which
2221 allows you to view your last query that was run.
2222- Added a new mime type to the upload class for better compatibility.
2223- Changed how cache files are read to prevent PHP errors if the cache
2224 file contains an XML tag, which PHP wants to interpret as a short
2225 tag.
2226- Fixed a bug in a couple of the active record functions (where and
2227 orderby).
2228- Fixed a bug in the image library when realpath() returns false.

2233
2234Version 1.3
2235===========
2236
2237Release Date: April 3, 2006
2238
2239- Added support for :doc:`Models <general/models>`.
2240- Redesigned the database libraries to support additional RDBMs
2241 (Postgres, MySQLi, etc.).
2242- Redesigned the :doc:`Active Record class <./database/active_record>`
2243 to enable more varied types of queries with simpler syntax, and
2244 advanced features like JOINs.
2245- Added a feature to the database class that lets you run :doc:`custom
2246 function calls <./database/call_function>`.
2247- Added support for :doc:`private functions <general/controllers>` in your
2248 controllers. Any controller function name that starts with an
2249 underscore will not be served by a URI request.
2250- Added the ability to pass your own initialization parameters to your
2251 :doc:`custom core libraries <general/creating_libraries>` when using
2252 $this->load->library()
2253- Added support for running standard :doc:`query string URLs <general/urls>`.
2254 These can be optionally enabled in your config file.
2255- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
2256 appended to your URLs. For example, you could add .html to your URLs,
2257 making them appear static. This feature is enabled in your config
2258 file.
2259- Added a new error template for use with native PHP errors.
2260- Added "alternator" function in the :doc:`string
2261 helpers <./helpers/string_helper>`.
2262- Removed slashing from the input class. After much debate we decided
2263 to kill this feature.
2264- Change the commenting style in the scripts to the PEAR standard so
2265 that IDEs and tools like phpDocumenter can harvest the comments.
2266- Added better class and function name-spacing to avoid collisions with
2267 user developed classes. All CodeIgniter classes are now prefixed with
2268 CI\_ and all controller methods are prefixed with _ci to avoid
2269 controller collisions. A list of reserved function names can be
2270 :doc:`found here <general/controllers>`.
2271- Redesigned how the "CI" super object is referenced, depending on
2272 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2273 way to manage objects that utilizes a bit less resources.
2274- Deprecated: $this->db->use_table() has been deprecated. Please read
2275 the :doc:`Active Record <./database/active_record>` page for
2276 information.
2277- Deprecated: $this->db->smart_escape_str() has been deprecated.
2278 Please use this instead: $this->db->escape()
2279- Fixed a bug in the exception handler which was preventing some PHP
2280 errors from showing up.
2281- Fixed a typo in the URI class. $this->total_segment() should be
2282 plural: $this->total_segments()
2283- Fixed some typos in the default calendar template
2284- Fixed some typos in the user guide
2285

2289Release Date: March 21, 2006
2290
2291- Redesigned some internal aspects of the framework to resolve scoping
2292 problems that surfaced during the beta tests. The problem was most
2293 notable when instantiating classes in your constructors, particularly
2294 if those classes in turn did work in their constructors.
2295- Added a global function named
2296 :doc:`get_instance() <general/ancillary_classes>` allowing the main
2297 CodeIgniter object to be accessible throughout your own classes.
2298- Added new :doc:`File Helper <./helpers/file_helper>`:
2299 delete_files()
2300- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2301 index_page()
2302- Added the ability to create your own :doc:`core
2303 libraries <general/creating_libraries>` and store them in your local
2304 application directory.
2305- Added an overwrite option to the :doc:`Upload
2306 class <./libraries/file_uploading>`, enabling files to be
2307 overwritten rather than having the file name appended.
2308- Added Javascript Calendar plugin.
2309- Added search feature to user guide. Note: This is done using Google,
2310 which at the time of this writing has not crawled all the pages of
2311 the docs.
2312- Updated the parser class so that it allows tag pars within other tag
2313 pairs.
2314- Fixed a bug in the DB "where" function.
2315- Fixed a bug that was preventing custom config files to be
2316 auto-loaded.

2328 applications <general/managing_apps>` that share a common CodeIgniter
2329 backend.
2330- Moved the "uri protocol" variable from the index.php file into the
2331 config.php file
2332- Fixed a problem that was preventing certain function calls from
2333 working within constructors.

2341- Fixed a bug that was preventing the xss_clean function from being
2342 called from the validation class.
