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

235 library <libraries/loader>` to retrieve global vars set with
236 $this->load->view() and $this->load->vars().
237 - Changed $this->db->having() to insert quotes using escape() rather
238 than escape_str().
239

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

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

Derek Jones8ede1a22011-10-05 13:34:52 -0500379Version 2.0.0
380=============
381
382Release Date: January 28, 2011
383Hg Tag: v2.0.0
384
385- General changes
386
387 - PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.
388 - Scaffolding, having been deprecated for a number of versions, has
389 been removed.
390 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
391 has been converted to a Helper and
392 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
393 calendar plugin was removed due to the ready availability of great
394 JavaScript calendars, particularly with jQuery.
395 - Added new special Library type:
396 :doc:`Drivers <./general/drivers>`.
397 - Added full query-string support. See the config file for details.
398 - Moved the application folder outside of the system folder.
399 - Moved system/cache and system/logs directories to the application
400 directory.
401 - Added routing overrides to the main index.php file, enabling the
402 normal routing to be overridden on a per "index" file basis.
403 - Added the ability to set config values (or override config values)
404 directly from data set in the main index.php file. This allows a
405 single application to be used with multiple front controllers,
406 each having its own config values.
407 - Added $config['directory_trigger'] to the config file so that a
408 controller sub-directory can be specified when running _GET
409 strings instead of URI segments.
410 - Added ability to set "Package" paths - specific paths where the
411 Loader and Config classes should try to look first for a requested
412 file. This allows distribution of sub-applications with their own
413 libraries, models, config files, etc. in a single "package"
414 directory. See the :doc:`Loader class <libraries/loader>`
415 documentation for more details.
416 - In-development code is now hosted at
417 `BitBucket <http://bitbucket.org/ellislab/codeigniter-reactor/>`_.
418 - Removed the deprecated Validation Class.
419 - Added CI\_ Prefix to all core classes.
420 - Package paths can now be set in application/config/autoload.php.
kenjis087a7a82011-10-20 20:08:47 +0900421 - :doc:`Upload library <libraries/file_uploading>` file_name can
Derek Jones8ede1a22011-10-05 13:34:52 -0500422 now be set without an extension, the extension will be taken from
423 the uploaded file instead of the given name.
424 - In :doc:`Database Forge <database/forge>` the name can be omitted
425 from $this->dbforge->modify_column()'s 2nd param if you aren't
426 changing the name.
427 - $config['base_url'] is now empty by default and will guess what
428 it should be.
429 - Enabled full Command Line Interface compatibility with
430 config['uri_protocol'] = 'CLI';.
431
432- Libraries
433
434 - Added a :doc:`Cache driver <libraries/caching>` with APC,

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

459 Table library
460 - Added a parse_string() method to the :doc:`Parser

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

903===========
904
905Release Date: October 23, 2008
906Hg Tag: 1.7.0
907
908- Libraries
909
910 - Added a new :doc:`Form Validation
911 Class <libraries/form_validation>`. It simplifies setting
912 rules and field names, supports arrays as field names, allows
913 groups of validation rules to be saved in a config file, and adds
914 some helper functions for use in view files. **Please note that
915 the old Validation class is now deprecated**. We will leave it in
916 the library folder for some time so that existing applications
917 that use it will not break, but you are encouraged to migrate to
918 the new version.
919 - Updated the :doc:`Sessions class <libraries/sessions>` so that
920 any custom data being saved gets stored to a database rather than
921 the session cookie (assuming you are using a database to store
922 session data), permitting much more data to be saved.
923 - Added the ability to store libraries in subdirectories within
924 either the main "libraries" or the local application "libraries"
925 folder. Please see the :doc:`Loader class <libraries/loader>` for
926 more info.
927 - Added the ability to assign library objects to your own variable
928 names when you use $this->load->library(). Please see the :doc:`Loader
929 class <libraries/loader>` for more info.
930 - Added controller class/method info to :doc:`Profiler
931 class <general/profiling>` and support for multiple database
932 connections.
933 - Improved the "auto typography" feature and moved it out of the
934 helper into its own :doc:`Typography
935 Class <libraries/typography>`.
936 - Improved performance and accuracy of xss_clean(), including
937 reduction of false positives on image/file tests.
938 - Improved :doc:`Parser class <./libraries/parser>` to allow
939 multiple calls to the parse() function. The output of each is
940 appended in the output.
941 - Added max_filename option to set a file name length limit in the
942 :doc:`File Upload Class <libraries/file_uploading>`.
943 - Added set_status_header() function to :doc:`Output
944 class <libraries/output>`.
945 - Modified :doc:`Pagination <libraries/pagination>` class to only
946 output the "First" link when the link for page one would not be
947 shown.
948 - Added support for mb_strlen in the :doc:`Form
949 Validation <libraries/form_validation>` class so that
950 multi-byte languages will calculate string lengths properly.
951
952- Database
953
954 - Improved Active Record class to allow full path column and table
955 names: hostname.database.table.column. Also improved the alias
956 handling.
957 - Improved how table and column names are escaped and prefixed. It
958 now honors full path names when adding prefixes and escaping.
959 - Added Active Record caching feature to "update" and "delete"
960 functions.
961 - Added removal of non-printing control characters in escape_str()
962 of DB drivers that do not have native PHP escaping mechanisms
963 (mssql, oci8, odbc), to avoid potential SQL errors, and possible
964 sources of SQL injection.
965 - Added port support to MySQL, MySQLi, and MS SQL database drivers.
966 - Added driver name variable in each DB driver, based on bug report
967 #4436.
968
969- Helpers
970
971 - Added several new "setting" functions to the :doc:`Form
972 helper <helpers/form_helper>` that allow POST data to be
973 retrieved and set into forms. These are intended to be used on
974 their own, or with the new :doc:`Form Validation
975 Class <libraries/form_validation>`.
976 - Added current_url() and uri_segments() to :doc:`URL
977 helper <helpers/url_helper>`.
978 - Altered auto_link() in the :doc:`URL
979 helper <helpers/url_helper>` so that email addresses with
980 "+" included will be linked.
981 - Added meta() function to :doc:`HTML
982 helper <helpers/html_helper>`.
983 - Improved accuracy of calculations in :doc:`Number
984 helper <helpers/number_helper>`.
985 - Removed added newlines ("\\n") from most form and html helper
986 functions.
987 - Tightened up validation in the :doc:`Date
988 helper <helpers/date_helper>` function human_to_unix(),
989 and eliminated the POSIX regex.
990 - Updated :doc:`Date helper <helpers/date_helper>` to match the
991 world's current time zones and offsets.
992 - Modified url_title() in the :doc:`URL
993 helper <helpers/url_helper>` to remove characters and digits
994 that are part of character entities, to allow dashes, underscores,
995 and periods regardless of the $separator, and to allow uppercase
996 characters.
997 - Added support for arbitrary attributes in anchor_popup() of the
998 :doc:`URL helper <helpers/url_helper>`.
999
1000- Other Changes
1001
1002 - Added :doc:`PHP Style Guide <./general/styleguide>` to docs.
1003 - Added sanitization in xss_clean() for a deprecated HTML tag that
1004 could be abused in user input in Internet Explorer.
1005 - Added a few openxml document mime types, and an additional mobile
1006 agent to mimes.php and user_agents.php respectively.
1007 - Added a file lock check during caching, before trying to write to
1008 the file.
1009 - Modified Cookie key cleaning to unset a few troublesome key names
1010 that can be present in certain environments, preventing CI from
1011 halting execution.
1012 - Changed the output of the profiler to use style attribute rather
1013 than clear, and added the id "codeigniter_profiler" to the
1014 container div.

1883=============
1884
1885Release Date: September 21, 2006
1886
1887- Added a new feature that passes URI segments directly to your
1888 function calls as parameters. See the
1889 :doc:`Controllers <general/controllers>` page for more info.
1890- Added support for a function named _output(), which when used in
1891 your controllers will received the final rendered output from the
1892 output class. More info in the :doc:`Controllers <general/controllers>`
1893 page.
1894- Added several new functions in the :doc:`URI
1895 Class <./libraries/uri>` to let you retrieve and manipulate URI
1896 segments that have been re-routed using the :doc:`URI
1897 Routing <general/routing>` feature. Previously, the URI class did not
1898 permit you to access any re-routed URI segments, but now it does.
1899- Added :doc:`$this->output->set_header() <./libraries/output>`
1900 function, which allows you to set server headers.
1901- Updated plugins, helpers, and language classes to allow your
1902 application folder to contain its own plugins, helpers, and language
1903 folders. Previously they were always treated as global for your
1904 entire installation. If your application folder contains any of these
1905 resources they will be used *instead* the global ones.
1906- Added :doc:`Inflector helper <./helpers/inflector_helper>`.
1907- Added element() function in the :doc:`array
1908 helper <./helpers/array_helper>`.
1909- Added RAND() to active record orderby() function.
1910- Added delete_cookie() and get_cookie() to :doc:`Cookie
1911 helper <./helpers/cookie_helper>`, even though the input class
1912 has a cookie fetching function.
1913- Added Oracle database driver (still undergoing testing so it might
1914 have some bugs).
1915- Added the ability to combine pseudo-variables and php variables in
1916 the template parser class.
1917- Added output compression option to the config file.
1918- Removed the is_numeric test from the db->escape() function.
1919- Fixed a MySQLi bug that was causing error messages not to contain
1920 proper error data.
1921- Fixed a bug in the email class which was causing it to ignore
1922 explicitly set alternative headers.
1923- Fixed a bug that was causing a PHP error when the Exceptions class
1924 was called within the get_config() function since it was causing
1925 problems.
1926- Fixed an oversight in the cookie helper in which the config file
1927 cookie settings were not being honored.
1928- Fixed an oversight in the upload class. An item mentioned in the 1.4
1929 changelog was missing.
1930- Added some code to allow email attachments to be reset when sending
1931 batches of email.
1932- Deprecated the application/scripts folder. It will continue to work
1933 for legacy users, but it is recommended that you create your own
1934 :doc:`libraries <./general/libraries>` or
1935 :doc:`models <./general/models>` instead. It was originally added
1936 before CI had user libraries or models, but it's not needed anymore.
1937- Deprecated the $autoload['core'] item from the autoload.php file.
1938 Instead, please now use: $autoload['libraries']
1939- Deprecated the following database functions:
1940 $this->db->smart_escape_str() and $this->db->fields().

1948 into and modify the inner workings of the framework without hacking
1949 the core files.
1950- Added the ability to organize controller files :doc:`into
1951 sub-folders <general/controllers>`. Kudos to Marco for
1952 `suggesting <http://codeigniter.com/forums/viewthread/627/>`_ this
1953 (and the next two) feature.
kenjis087a7a82011-10-20 20:08:47 +09001954- Added regular expressions support for :doc:`routing

1970 file in the applications/config/ folder.
1971- Updated the Upload class to allow the upload field name to be set
1972 when calling :doc:`do_upload() <./libraries/file_uploading>`.
1973- Updated the :doc:`Config Library <./libraries/config>` to be able to
1974 load config files silently, and to be able to assign config files to
1975 their own index (to avoid collisions if you use multiple config
1976 files).
1977- Updated the URI Protocol code to allow more options so that URLs will
1978 work more reliably in different environments.
1979- Updated the form_open() helper to allow the GET method to be used.
1980- Updated the MySQLi execute() function with some code to help prevent
1981 lost connection errors.
1982- Updated the SQLite Driver to check for object support before
1983 attempting to return results as objects. If unsupported it returns an

1994- Renamed display() to _display() in the Output class to make it clear
1995 that it's a private function.
1996- Deprecated the hash() function due to a naming conflict with a native
1997 PHP function with the same name. Please use dohash() instead.
1998- Fixed an bug that was preventing the input class from unsetting GET

2036
2037- Models do **not** connect automatically to the database as of this
2038 version. :doc:`More info here <./general/models>`.
2039- Updated the Sessions class to utilize the active record class when
2040 running session related queries. Previously the queries assumed MySQL

2061=============
2062
2063Release Date: April 17, 2006
2064
2065- Changed the behavior of the validation class such that if a
2066 "required" rule is NOT explicitly stated for a field then all other
2067 tests get ignored.
2068- Fixed a bug in the Controller class that was causing it to look in
2069 the local "init" folder instead of the main system one.
2070- Fixed a bug in the init_pagination file. The $config item was not

2082- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
2083- Added the ability to pass objects to the **insert()** and
2084 **update()** database functions. This feature enables you to (among
2085 other things) use your :doc:`Model class <./general/models>`
2086 variables to run queries with. See the Models page for details.
2087- Added the ability to pass objects to the :doc:`view loading
2088 function <./general/views>`: $this->load->view('my_view',
2089 $object);
2090- Added getwhere function to :doc:`Active Record
2091 class <./database/active_record>`.
2092- Added count_all function to :doc:`Active Record
2093 class <./database/active_record>`.
2094- Added language file for scaffolding and fixed a scaffolding bug that
2095 occurs when there are no rows in the specified table.
2096- Added :doc:`$this->db->last_query() <./database/queries>`, which
2097 allows you to view your last query that was run.
2098- Added a new mime type to the upload class for better compatibility.
2099- Changed how cache files are read to prevent PHP errors if the cache
2100 file contains an XML tag, which PHP wants to interpret as a short
2101 tag.
2102- Fixed a bug in a couple of the active record functions (where and
2103 orderby).
2104- Fixed a bug in the image library when realpath() returns false.

2109
2110Version 1.3
2111===========
2112
2113Release Date: April 3, 2006
2114
2115- Added support for :doc:`Models <general/models>`.
2116- Redesigned the database libraries to support additional RDBMs
2117 (Postgres, MySQLi, etc.).
2118- Redesigned the :doc:`Active Record class <./database/active_record>`
2119 to enable more varied types of queries with simpler syntax, and
2120 advanced features like JOINs.
2121- Added a feature to the database class that lets you run :doc:`custom
2122 function calls <./database/call_function>`.
2123- Added support for :doc:`private functions <general/controllers>` in your
2124 controllers. Any controller function name that starts with an
2125 underscore will not be served by a URI request.
2126- Added the ability to pass your own initialization parameters to your
2127 :doc:`custom core libraries <general/creating_libraries>` when using
2128 $this->load->library()
2129- Added support for running standard :doc:`query string URLs <general/urls>`.
2130 These can be optionally enabled in your config file.
2131- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
2132 appended to your URLs. For example, you could add .html to your URLs,
2133 making them appear static. This feature is enabled in your config
2134 file.
2135- Added a new error template for use with native PHP errors.
2136- Added "alternator" function in the :doc:`string
2137 helpers <./helpers/string_helper>`.
2138- Removed slashing from the input class. After much debate we decided
2139 to kill this feature.
2140- Change the commenting style in the scripts to the PEAR standard so
2141 that IDEs and tools like phpDocumenter can harvest the comments.
2142- Added better class and function name-spacing to avoid collisions with
2143 user developed classes. All CodeIgniter classes are now prefixed with
2144 CI\_ and all controller methods are prefixed with _ci to avoid
2145 controller collisions. A list of reserved function names can be
2146 :doc:`found here <general/controllers>`.
2147- Redesigned how the "CI" super object is referenced, depending on
2148 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2149 way to manage objects that utilizes a bit less resources.
2150- Deprecated: $this->db->use_table() has been deprecated. Please read
2151 the :doc:`Active Record <./database/active_record>` page for
2152 information.
2153- Deprecated: $this->db->smart_escape_str() has been deprecated.
2154 Please use this instead: $this->db->escape()
2155- Fixed a bug in the exception handler which was preventing some PHP
2156 errors from showing up.
2157- Fixed a typo in the URI class. $this->total_segment() should be
2158 plural: $this->total_segments()
2159- Fixed some typos in the default calendar template
2160- Fixed some typos in the user guide

2165Release Date: March 21, 2006
2166
2167- Redesigned some internal aspects of the framework to resolve scoping
2168 problems that surfaced during the beta tests. The problem was most
2169 notable when instantiating classes in your constructors, particularly
2170 if those classes in turn did work in their constructors.
2171- Added a global function named
2172 :doc:`get_instance() <general/ancillary_classes>` allowing the main
2173 CodeIgniter object to be accessible throughout your own classes.
2174- Added new :doc:`File Helper <./helpers/file_helper>`:
2175 delete_files()
2176- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2177 index_page()
2178- Added the ability to create your own :doc:`core
2179 libraries <general/creating_libraries>` and store them in your local
2180 application directory.
2181- Added an overwrite option to the :doc:`Upload
2182 class <./libraries/file_uploading>`, enabling files to be
2183 overwritten rather than having the file name appended.
2184- Added Javascript Calendar plugin.
2185- Added search feature to user guide. Note: This is done using Google,
2186 which at the time of this writing has not crawled all the pages of
2187 the docs.
2188- Updated the parser class so that it allows tag pars within other tag
2189 pairs.
2190- Fixed a bug in the DB "where" function.
2191- Fixed a bug that was preventing custom config files to be
