338Version 2.0.3
339=============
340
341Release Date: August 20, 2011
342
343- Security
344
345 - An improvement was made to the MySQL and MySQLi drivers to prevent
346 exposing a potential vector for SQL injection on sites using
347 multi-byte character sets in the database client connection.
348 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
349 *mysql_set_charset()* creates a situation where using multi-byte
350 character sets on these environments may potentially expose a SQL
351 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
352 character sets are unaffected on all environments.
353
354 If you are running or considering running a multi-byte character
355 set for your database connection, please pay close attention to
356 the server environment you are deploying on to ensure you are not
357 vulnerable.
358

424- Fixed a bug where not setting 'null' when adding fields in db_forge
425 for mysql and mysqli drivers would default to NULL instead of NOT
426 NULL as the docs suggest.
427- Fixed a bug where using $this->db->select_max(),
428 $this->db->select_min(), etc could throw notices. Thanks to w43l for
429 the patch.
430- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
431 whole is more reliable. This should get parameters in crontab
432 working.

545Release Date: January 28, 2011
546Hg Tag: v2.0.0
547
548- General changes
549
550 - PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.
551 - Scaffolding, having been deprecated for a number of versions, has
552 been removed.
553 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
554 has been converted to a Helper and
555 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
556 calendar plugin was removed due to the ready availability of great
557 JavaScript calendars, particularly with jQuery.
558 - Added new special Library type:
559 :doc:`Drivers <./general/drivers>`.
560 - Added full query-string support. See the config file for details.
561 - Moved the application folder outside of the system folder.
562 - Moved system/cache and system/logs directories to the application
563 directory.
564 - Added routing overrides to the main index.php file, enabling the
565 normal routing to be overridden on a per "index" file basis.
566 - Added the ability to set config values (or override config values)
567 directly from data set in the main index.php file. This allows a
568 single application to be used with multiple front controllers,
569 each having its own config values.
570 - Added $config['directory_trigger'] to the config file so that a
571 controller sub-directory can be specified when running _GET
572 strings instead of URI segments.
573 - Added ability to set "Package" paths - specific paths where the
574 Loader and Config classes should try to look first for a requested
575 file. This allows distribution of sub-applications with their own
576 libraries, models, config files, etc. in a single "package"
577 directory. See the :doc:`Loader class <libraries/loader>`
578 documentation for more details.
579 - In-development code is now hosted at
580 `BitBucket <http://bitbucket.org/ellislab/codeigniter-reactor/>`_.
581 - Removed the deprecated Validation Class.
582 - Added CI\_ Prefix to all core classes.
583 - Package paths can now be set in application/config/autoload.php.
kenjis087a7a82011-10-20 20:08:47 +0900584 - :doc:`Upload library <libraries/file_uploading>` file_name can
Derek Jones8ede1a22011-10-05 13:34:52 -0500585 now be set without an extension, the extension will be taken from
586 the uploaded file instead of the given name.
587 - In :doc:`Database Forge <database/forge>` the name can be omitted
588 from $this->dbforge->modify_column()'s 2nd param if you aren't
589 changing the name.
590 - $config['base_url'] is now empty by default and will guess what
591 it should be.
592 - Enabled full Command Line Interface compatibility with
593 config['uri_protocol'] = 'CLI';.
594
595- Libraries
596
597 - Added a :doc:`Cache driver <libraries/caching>` with APC,

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

614 - Added an 'object' config variable to the XML-RPC Server library so
615 that one can specify the object to look for requested methods,
616 instead of assuming it is in the $CI superobject.
617 - Added "is_object" into the list of unit tests capable of being
618 run.
619 - Table library will generate an empty cell with a blank string, or
620 NULL value.
621 - Added ability to set tag attributes for individual cells in the
622 Table library
623 - Added a parse_string() method to the :doc:`Parser
624 Class <libraries/parser>`.

634 control over the use of the Security library's xss_clean()
635 method.

641 type value to standardize input in Upload library.
642 - Added a second parameter (boolean) to
643 $this->zip->read_dir('/path/to/directory', FALSE) to remove the
644 preceding trail of empty folders when creating a Zip archive. This
645 example would contain a zip with "directory" and all of its
646 contents.
647 - Added ability in the Image Library to handle PNG transparency for
648 resize operations when using the GD lib.
649 - Modified the Session class to prevent use if no encryption key is
650 set in the config file.
651 - Added a new config item to the Session class
652 sess_expire_on_close to allow sessions to auto-expire when the

655 Mcrypt is available.
656 - Changed the default encryption mode in the Encryption library to
657 CBC.

1069Hg Tag: 1.7.0
1070
1071- Libraries
1072
1073 - Added a new :doc:`Form Validation
1074 Class <libraries/form_validation>`. It simplifies setting
1075 rules and field names, supports arrays as field names, allows
1076 groups of validation rules to be saved in a config file, and adds
1077 some helper functions for use in view files. **Please note that
1078 the old Validation class is now deprecated**. We will leave it in
1079 the library folder for some time so that existing applications
1080 that use it will not break, but you are encouraged to migrate to
1081 the new version.
1082 - Updated the :doc:`Sessions class <libraries/sessions>` so that
1083 any custom data being saved gets stored to a database rather than
1084 the session cookie (assuming you are using a database to store
1085 session data), permitting much more data to be saved.
1086 - Added the ability to store libraries in subdirectories within
1087 either the main "libraries" or the local application "libraries"
1088 folder. Please see the :doc:`Loader class <libraries/loader>` for
1089 more info.
1090 - Added the ability to assign library objects to your own variable
1091 names when you use $this->load->library(). Please see the :doc:`Loader
1092 class <libraries/loader>` for more info.
1093 - Added controller class/method info to :doc:`Profiler
1094 class <general/profiling>` and support for multiple database
1095 connections.
1096 - Improved the "auto typography" feature and moved it out of the
1097 helper into its own :doc:`Typography
1098 Class <libraries/typography>`.
1099 - Improved performance and accuracy of xss_clean(), including
1100 reduction of false positives on image/file tests.
1101 - Improved :doc:`Parser class <./libraries/parser>` to allow
1102 multiple calls to the parse() function. The output of each is
1103 appended in the output.
1104 - Added max_filename option to set a file name length limit in the
1105 :doc:`File Upload Class <libraries/file_uploading>`.
1106 - Added set_status_header() function to :doc:`Output
1107 class <libraries/output>`.
1108 - Modified :doc:`Pagination <libraries/pagination>` class to only
1109 output the "First" link when the link for page one would not be
1110 shown.
1111 - Added support for mb_strlen in the :doc:`Form
1112 Validation <libraries/form_validation>` class so that
1113 multi-byte languages will calculate string lengths properly.
1114
1115- Database
1116
1117 - Improved Active Record class to allow full path column and table
1118 names: hostname.database.table.column. Also improved the alias
1119 handling.
1120 - Improved how table and column names are escaped and prefixed. It
1121 now honors full path names when adding prefixes and escaping.
1122 - Added Active Record caching feature to "update" and "delete"
1123 functions.
1124 - Added removal of non-printing control characters in escape_str()
1125 of DB drivers that do not have native PHP escaping mechanisms
1126 (mssql, oci8, odbc), to avoid potential SQL errors, and possible
1127 sources of SQL injection.
1128 - Added port support to MySQL, MySQLi, and MS SQL database drivers.
1129 - Added driver name variable in each DB driver, based on bug report
1130 #4436.
1131
1132- Helpers
1133
1134 - Added several new "setting" functions to the :doc:`Form
1135 helper <helpers/form_helper>` that allow POST data to be
1136 retrieved and set into forms. These are intended to be used on
1137 their own, or with the new :doc:`Form Validation
1138 Class <libraries/form_validation>`.
1139 - Added current_url() and uri_segments() to :doc:`URL
1140 helper <helpers/url_helper>`.
1141 - Altered auto_link() in the :doc:`URL
1142 helper <helpers/url_helper>` so that email addresses with
1143 "+" included will be linked.
1144 - Added meta() function to :doc:`HTML
1145 helper <helpers/html_helper>`.
1146 - Improved accuracy of calculations in :doc:`Number
1147 helper <helpers/number_helper>`.
1148 - Removed added newlines ("\\n") from most form and html helper
1149 functions.
1150 - Tightened up validation in the :doc:`Date
1151 helper <helpers/date_helper>` function human_to_unix(),
1152 and eliminated the POSIX regex.
1153 - Updated :doc:`Date helper <helpers/date_helper>` to match the
1154 world's current time zones and offsets.
1155 - Modified url_title() in the :doc:`URL
1156 helper <helpers/url_helper>` to remove characters and digits
1157 that are part of character entities, to allow dashes, underscores,
1158 and periods regardless of the $separator, and to allow uppercase
1159 characters.
1160 - Added support for arbitrary attributes in anchor_popup() of the
1161 :doc:`URL helper <helpers/url_helper>`.
1162
1163- Other Changes
1164
1165 - Added :doc:`PHP Style Guide <./general/styleguide>` to docs.
1166 - Added sanitization in xss_clean() for a deprecated HTML tag that
1167 could be abused in user input in Internet Explorer.
1168 - Added a few openxml document mime types, and an additional mobile
1169 agent to mimes.php and user_agents.php respectively.
1170 - Added a file lock check during caching, before trying to write to
1171 the file.
1172 - Modified Cookie key cleaning to unset a few troublesome key names
1173 that can be present in certain environments, preventing CI from
1174 halting execution.
1175 - Changed the output of the profiler to use style attribute rather
1176 than clear, and added the id "codeigniter_profiler" to the
1177 container div.

2047
2048Release Date: September 21, 2006
2049

2055 output class. More info in the :doc:`Controllers <general/controllers>`
2056 page.
2057- Added several new functions in the :doc:`URI
2058 Class <./libraries/uri>` to let you retrieve and manipulate URI
2059 segments that have been re-routed using the :doc:`URI
2060 Routing <general/routing>` feature. Previously, the URI class did not
2061 permit you to access any re-routed URI segments, but now it does.
2062- Added :doc:`$this->output->set_header() <./libraries/output>`
2063 function, which allows you to set server headers.
2064- Updated plugins, helpers, and language classes to allow your
2065 application folder to contain its own plugins, helpers, and language
2066 folders. Previously they were always treated as global for your
2067 entire installation. If your application folder contains any of these
2068 resources they will be used *instead* the global ones.
2069- Added :doc:`Inflector helper <./helpers/inflector_helper>`.
2070- Added element() function in the :doc:`array
2071 helper <./helpers/array_helper>`.
2072- Added RAND() to active record orderby() function.
2073- Added delete_cookie() and get_cookie() to :doc:`Cookie
2074 helper <./helpers/cookie_helper>`, even though the input class
2075 has a cookie fetching function.
2076- Added Oracle database driver (still undergoing testing so it might
2077 have some bugs).
2078- Added the ability to combine pseudo-variables and php variables in
2079 the template parser class.
2080- Added output compression option to the config file.
2081- Removed the is_numeric test from the db->escape() function.
2082- Fixed a MySQLi bug that was causing error messages not to contain
2083 proper error data.

2085 explicitly set alternative headers.
2086- Fixed a bug that was causing a PHP error when the Exceptions class
2087 was called within the get_config() function since it was causing
2088 problems.
2089- Fixed an oversight in the cookie helper in which the config file
2090 cookie settings were not being honored.
2091- Fixed an oversight in the upload class. An item mentioned in the 1.4
2092 changelog was missing.
2093- Added some code to allow email attachments to be reset when sending
2094 batches of email.
2095- Deprecated the application/scripts folder. It will continue to work
2096 for legacy users, but it is recommended that you create your own
2097 :doc:`libraries <./general/libraries>` or
2098 :doc:`models <./general/models>` instead. It was originally added
2099 before CI had user libraries or models, but it's not needed anymore.
2100- Deprecated the $autoload['core'] item from the autoload.php file.
2101 Instead, please now use: $autoload['libraries']
2102- Deprecated the following database functions:
2103 $this->db->smart_escape_str() and $this->db->fields().

2111 into and modify the inner workings of the framework without hacking
2112 the core files.
2113- Added the ability to organize controller files :doc:`into
2114 sub-folders <general/controllers>`. Kudos to Marco for
2115 `suggesting <http://codeigniter.com/forums/viewthread/627/>`_ this
2116 (and the next two) feature.
kenjis087a7a82011-10-20 20:08:47 +09002117- Added regular expressions support for :doc:`routing

2128- Added support for changing the port number in the :doc:`Postgres
2129 driver <./database/configuration>`.
2130- Moved the list of "allowed URI characters" out of the Router class
2131 and into the config file.
2132- Moved the MIME type array out of the Upload class and into its own
2133 file in the applications/config/ folder.
2134- Updated the Upload class to allow the upload field name to be set
2135 when calling :doc:`do_upload() <./libraries/file_uploading>`.
2136- Updated the :doc:`Config Library <./libraries/config>` to be able to
2137 load config files silently, and to be able to assign config files to
2138 their own index (to avoid collisions if you use multiple config
2139 files).
2140- Updated the URI Protocol code to allow more options so that URLs will
2141 work more reliably in different environments.
2142- Updated the form_open() helper to allow the GET method to be used.
2143- Updated the MySQLi execute() function with some code to help prevent
2144 lost connection errors.
2145- Updated the SQLite Driver to check for object support before
2146 attempting to return results as objects. If unsupported it returns an

2157- Renamed display() to _display() in the Output class to make it clear
2158 that it's a private function.
2159- Deprecated the hash() function due to a naming conflict with a native
2160 PHP function with the same name. Please use dohash() instead.
2161- Fixed an bug that was preventing the input class from unsetting GET

2199
2200- Models do **not** connect automatically to the database as of this
2201 version. :doc:`More info here <./general/models>`.
2202- Updated the Sessions class to utilize the active record class when
2203 running session related queries. Previously the queries assumed MySQL
2204 syntax.

2206 arguments, allowing multiple calls.
2207- Fixed a bug in the active record "having" function.
2208- Fixed a problem in the validation class which was making checkboxes
2209 be ignored when required.

2213 some versions of html_entity_decode.
2214- Fixed a validation bug that was preventing rules from being set twice
2215 in one controller.

2224=============
2225
2226Release Date: April 17, 2006
2227
2228- Changed the behavior of the validation class such that if a
2229 "required" rule is NOT explicitly stated for a field then all other
2230 tests get ignored.
2231- Fixed a bug in the Controller class that was causing it to look in
2232 the local "init" folder instead of the main system one.
2233- Fixed a bug in the init_pagination file. The $config item was not
2234 being set correctly.

2245- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
2246- Added the ability to pass objects to the **insert()** and
2247 **update()** database functions. This feature enables you to (among
2248 other things) use your :doc:`Model class <./general/models>`
2249 variables to run queries with. See the Models page for details.
2250- Added the ability to pass objects to the :doc:`view loading
2251 function <./general/views>`: $this->load->view('my_view',
2252 $object);
2253- Added getwhere function to :doc:`Active Record
2254 class <./database/active_record>`.
2255- Added count_all function to :doc:`Active Record
2256 class <./database/active_record>`.
2257- Added language file for scaffolding and fixed a scaffolding bug that
2258 occurs when there are no rows in the specified table.
2259- Added :doc:`$this->db->last_query() <./database/queries>`, which
2260 allows you to view your last query that was run.
2261- Added a new mime type to the upload class for better compatibility.
2262- Changed how cache files are read to prevent PHP errors if the cache
2263 file contains an XML tag, which PHP wants to interpret as a short
2264 tag.
2265- Fixed a bug in a couple of the active record functions (where and
2266 orderby).
2267- Fixed a bug in the image library when realpath() returns false.

2272
2273Version 1.3
2274===========
2275
2276Release Date: April 3, 2006
2277
2278- Added support for :doc:`Models <general/models>`.
2279- Redesigned the database libraries to support additional RDBMs
2280 (Postgres, MySQLi, etc.).
2281- Redesigned the :doc:`Active Record class <./database/active_record>`
2282 to enable more varied types of queries with simpler syntax, and
2283 advanced features like JOINs.
2284- Added a feature to the database class that lets you run :doc:`custom
2285 function calls <./database/call_function>`.
2286- Added support for :doc:`private functions <general/controllers>` in your
2287 controllers. Any controller function name that starts with an
2288 underscore will not be served by a URI request.
2289- Added the ability to pass your own initialization parameters to your
2290 :doc:`custom core libraries <general/creating_libraries>` when using
2291 $this->load->library()
2292- Added support for running standard :doc:`query string URLs <general/urls>`.
2293 These can be optionally enabled in your config file.
2294- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
2295 appended to your URLs. For example, you could add .html to your URLs,
2296 making them appear static. This feature is enabled in your config
2297 file.
2298- Added a new error template for use with native PHP errors.
2299- Added "alternator" function in the :doc:`string
2300 helpers <./helpers/string_helper>`.
2301- Removed slashing from the input class. After much debate we decided
2302 to kill this feature.
2303- Change the commenting style in the scripts to the PEAR standard so
2304 that IDEs and tools like phpDocumenter can harvest the comments.
2305- Added better class and function name-spacing to avoid collisions with
2306 user developed classes. All CodeIgniter classes are now prefixed with
2307 CI\_ and all controller methods are prefixed with _ci to avoid
2308 controller collisions. A list of reserved function names can be
2309 :doc:`found here <general/controllers>`.
2310- Redesigned how the "CI" super object is referenced, depending on
2311 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2312 way to manage objects that utilizes a bit less resources.
2313- Deprecated: $this->db->use_table() has been deprecated. Please read
2314 the :doc:`Active Record <./database/active_record>` page for
2315 information.
2316- Deprecated: $this->db->smart_escape_str() has been deprecated.
2317 Please use this instead: $this->db->escape()
2318- Fixed a bug in the exception handler which was preventing some PHP
2319 errors from showing up.
2320- Fixed a typo in the URI class. $this->total_segment() should be
2321 plural: $this->total_segments()
2322- Fixed some typos in the default calendar template
2323- Fixed some typos in the user guide
2324
2325Version 1.2
2326===========
2327
2328Release Date: March 21, 2006
2329
2330- Redesigned some internal aspects of the framework to resolve scoping
2331 problems that surfaced during the beta tests. The problem was most
2332 notable when instantiating classes in your constructors, particularly
2333 if those classes in turn did work in their constructors.
2334- Added a global function named
2335 :doc:`get_instance() <general/ancillary_classes>` allowing the main
2336 CodeIgniter object to be accessible throughout your own classes.
2337- Added new :doc:`File Helper <./helpers/file_helper>`:
2338 delete_files()
2339- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2340 index_page()
2341- Added the ability to create your own :doc:`core
2342 libraries <general/creating_libraries>` and store them in your local
2343 application directory.
2344- Added an overwrite option to the :doc:`Upload
2345 class <./libraries/file_uploading>`, enabling files to be
2346 overwritten rather than having the file name appended.
2347- Added Javascript Calendar plugin.
2348- Added search feature to user guide. Note: This is done using Google,
2349 which at the time of this writing has not crawled all the pages of
2350 the docs.
2351- Updated the parser class so that it allows tag pars within other tag
2352 pairs.
2353- Fixed a bug in the DB "where" function.
2354- Fixed a bug that was preventing custom config files to be
2355 auto-loaded.
2356- Fixed a bug in the mysql class bind feature that prevented question
2357 marks in the replacement data.
2358- Fixed some bugs in the xss_clean function
