160Version 2.0.3
161=============
162
163Release Date: August 20, 2011
164
165- Security
166
167 - An improvement was made to the MySQL and MySQLi drivers to prevent
168 exposing a potential vector for SQL injection on sites using
169 multi-byte character sets in the database client connection.
170 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
171 *mysql_set_charset()* creates a situation where using multi-byte
172 character sets on these environments may potentially expose a SQL
173 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
174 character sets are unaffected on all environments.
175
176 If you are running or considering running a multi-byte character
177 set for your database connection, please pay close attention to
178 the server environment you are deploying on to ensure you are not
179 vulnerable.

Timothy Warren01b56bc2011-10-10 10:45:45 -0400196 - Fixed a bug where :doc:`Email library <libraries/email>`
Derek Jones8ede1a22011-10-05 13:34:52 -0500197 attachments with a "." in the name would using invalid MIME-types.
Derek Jones8ede1a22011-10-05 13:34:52 -0500198

200
201 - Added an optional third parameter to heading() which allows adding
202 html attributes to the rendered heading tag.
203 - form_open() now only adds a hidden (Cross-site Reference Forgery)
204 protection field when the form's action is internal and is set to
205 the post method. (Reactor #165)

207 helper <helpers/inflector_helper>` to support considerably
208 more words.

211
212 - Altered Session to use a longer match against the user_agent

214 - Added $this->db->set_dbprefix() to the :doc:`Database
215 Driver <database/queries>`.
216 - Changed $this->cart->insert() in the :doc:`Cart

218 item was inserted successfully.
219 - Added $this->load->get_var() to the :doc:`Loader
220 library <libraries/loader>` to retrieve global vars set with
221 $this->load->view() and $this->load->vars().
222 - Changed $this->db->having() to insert quotes using escape() rather
223 than escape_str().
224
225Bug fixes for 2.0.3
226-------------------
227
228- Added ENVIRONMENT to reserved constants. (Reactor #196)
229- Changed server check to ensure SCRIPT_NAME is defined. (Reactor #57)

245 of all items in the cart instead of your total count.
246- Fixed a bug where not setting 'null' when adding fields in db_forge
247 for mysql and mysqli drivers would default to NULL instead of NOT
248 NULL as the docs suggest.
249- Fixed a bug where using $this->db->select_max(),
250 $this->db->select_min(), etc could throw notices. Thanks to w43l for
251 the patch.
252- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
253 whole is more reliable. This should get parameters in crontab
254 working.

367Release Date: January 28, 2011
368Hg Tag: v2.0.0
369
370- General changes
371
372 - PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.
373 - Scaffolding, having been deprecated for a number of versions, has
374 been removed.
375 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
376 has been converted to a Helper and
377 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
378 calendar plugin was removed due to the ready availability of great
379 JavaScript calendars, particularly with jQuery.
380 - Added new special Library type:
381 :doc:`Drivers <./general/drivers>`.
382 - Added full query-string support. See the config file for details.
383 - Moved the application folder outside of the system folder.
384 - Moved system/cache and system/logs directories to the application
385 directory.
386 - Added routing overrides to the main index.php file, enabling the
387 normal routing to be overridden on a per "index" file basis.
388 - Added the ability to set config values (or override config values)
389 directly from data set in the main index.php file. This allows a
390 single application to be used with multiple front controllers,
391 each having its own config values.
392 - Added $config['directory_trigger'] to the config file so that a
393 controller sub-directory can be specified when running _GET
394 strings instead of URI segments.
395 - Added ability to set "Package" paths - specific paths where the
396 Loader and Config classes should try to look first for a requested
397 file. This allows distribution of sub-applications with their own
398 libraries, models, config files, etc. in a single "package"
399 directory. See the :doc:`Loader class <libraries/loader>`
400 documentation for more details.
401 - In-development code is now hosted at
402 `BitBucket <http://bitbucket.org/ellislab/codeigniter-reactor/>`_.
403 - Removed the deprecated Validation Class.
404 - Added CI\_ Prefix to all core classes.
405 - Package paths can now be set in application/config/autoload.php.

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

1836 that are arrays to be run through the XSS filter.
1837- Documented three functions from the Validation
1838 class that were missing from the user
1839 guide: set_select(), set_radio(), and set_checkbox().

1849 is nested.
1850- Fixed a bug that caused CI to stop working when the PHP magic
1851 __get() or __set() functions were used within models or
1852 controllers.
1853- Fixed a pagination bug that was permitting negative values in the
1854 URL.
1855- Fixed an oversight in which the Loader class was not allowed to be
1856 extended.

1867Version 1.4.1
1868=============
1869
1870Release Date: September 21, 2006
1871
1872- Added a new feature that passes URI segments directly to your
1873 function calls as parameters. See the
1874 :doc:`Controllers <general/controllers>` page for more info.
1875- Added support for a function named _output(), which when used in
1876 your controllers will received the final rendered output from the
1877 output class. More info in the :doc:`Controllers <general/controllers>`
1878 page.
1879- Added several new functions in the :doc:`URI
1880 Class <./libraries/uri>` to let you retrieve and manipulate URI
1881 segments that have been re-routed using the :doc:`URI
1882 Routing <general/routing>` feature. Previously, the URI class did not
1883 permit you to access any re-routed URI segments, but now it does.
1884- Added :doc:`$this->output->set_header() <./libraries/output>`
1885 function, which allows you to set server headers.
1886- Updated plugins, helpers, and language classes to allow your
1887 application folder to contain its own plugins, helpers, and language
1888 folders. Previously they were always treated as global for your
1889 entire installation. If your application folder contains any of these
1890 resources they will be used *instead* the global ones.
1891- Added :doc:`Inflector helper <./helpers/inflector_helper>`.
1892- Added element() function in the :doc:`array
1893 helper <./helpers/array_helper>`.
1894- Added RAND() to active record orderby() function.
1895- Added delete_cookie() and get_cookie() to :doc:`Cookie
1896 helper <./helpers/cookie_helper>`, even though the input class
1897 has a cookie fetching function.
1898- Added Oracle database driver (still undergoing testing so it might
1899 have some bugs).
1900- Added the ability to combine pseudo-variables and php variables in
1901 the template parser class.
1902- Added output compression option to the config file.
1903- Removed the is_numeric test from the db->escape() function.
1904- Fixed a MySQLi bug that was causing error messages not to contain
1905 proper error data.
1906- Fixed a bug in the email class which was causing it to ignore
1907 explicitly set alternative headers.
1908- Fixed a bug that was causing a PHP error when the Exceptions class
1909 was called within the get_config() function since it was causing
1910 problems.
1911- Fixed an oversight in the cookie helper in which the config file
1912 cookie settings were not being honored.
1913- Fixed an oversight in the upload class. An item mentioned in the 1.4
1914 changelog was missing.
1915- Added some code to allow email attachments to be reset when sending
1916 batches of email.
1917- Deprecated the application/scripts folder. It will continue to work
1918 for legacy users, but it is recommended that you create your own
1919 :doc:`libraries <./general/libraries>` or
1920 :doc:`models <./general/models>` instead. It was originally added
1921 before CI had user libraries or models, but it's not needed anymore.
1922- Deprecated the $autoload['core'] item from the autoload.php file.
1923 Instead, please now use: $autoload['libraries']
1924- Deprecated the following database functions:
1925 $this->db->smart_escape_str() and $this->db->fields().

1930Release Date: September 17, 2006
1931
1932- Added :doc:`Hooks <./general/hooks>` feature, enabling you to tap
1933 into and modify the inner workings of the framework without hacking
1934 the core files.
1935- Added the ability to organize controller files :doc:`into
1936 sub-folders <general/controllers>`. Kudos to Marco for
1937 `suggesting <http://codeigniter.com/forums/viewthread/627/>`_ this
1938 (and the next two) feature.
kenjis087a7a82011-10-20 20:08:47 +09001939- Added regular expressions support for :doc:`routing

1949 helper.
1950- Added support for changing the port number in the :doc:`Postgres
1951 driver <./database/configuration>`.
1952- Moved the list of "allowed URI characters" out of the Router class
1953 and into the config file.
1954- Moved the MIME type array out of the Upload class and into its own
1955 file in the applications/config/ folder.
1956- Updated the Upload class to allow the upload field name to be set
1957 when calling :doc:`do_upload() <./libraries/file_uploading>`.
1958- Updated the :doc:`Config Library <./libraries/config>` to be able to
1959 load config files silently, and to be able to assign config files to
1960 their own index (to avoid collisions if you use multiple config
1961 files).
1962- Updated the URI Protocol code to allow more options so that URLs will
1963 work more reliably in different environments.
1964- Updated the form_open() helper to allow the GET method to be used.
1965- Updated the MySQLi execute() function with some code to help prevent
1966 lost connection errors.
1967- Updated the SQLite Driver to check for object support before
1968 attempting to return results as objects. If unsupported it returns an
1969 array.
1970- Updated the Models loader function to allow multiple loads of the
1971 same model.
1972- Updated the MS SQL driver so that single quotes are escaped.

1979- Renamed display() to _display() in the Output class to make it clear
1980 that it's a private function.
1981- Deprecated the hash() function due to a naming conflict with a native
1982 PHP function with the same name. Please use dohash() instead.
1983- Fixed an bug that was preventing the input class from unsetting GET
1984 variables.

1991 changing the case of certain words.
1992- Fixed some missing prefixes when using the database prefix feature.
1993- Fixed a typo in the Calendar class (cal_november).

2021
2022- Models do **not** connect automatically to the database as of this
2023 version. :doc:`More info here <./general/models>`.
2024- Updated the Sessions class to utilize the active record class when
2025 running session related queries. Previously the queries assumed MySQL
2026 syntax.

2028 arguments, allowing multiple calls.
2029- Fixed a bug in the active record "having" function.
2030- Fixed a problem in the validation class which was making checkboxes
2031 be ignored when required.

2035 some versions of html_entity_decode.
2036- Fixed a validation bug that was preventing rules from being set twice
2037 in one controller.

2046=============
2047
2048Release Date: April 17, 2006
2049
2050- Changed the behavior of the validation class such that if a
2051 "required" rule is NOT explicitly stated for a field then all other
2052 tests get ignored.
2053- Fixed a bug in the Controller class that was causing it to look in
2054 the local "init" folder instead of the main system one.
2055- Fixed a bug in the init_pagination file. The $config item was not
2056 being set correctly.

2067- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
2068- Added the ability to pass objects to the **insert()** and
2069 **update()** database functions. This feature enables you to (among
2070 other things) use your :doc:`Model class <./general/models>`
2071 variables to run queries with. See the Models page for details.
2072- Added the ability to pass objects to the :doc:`view loading
2073 function <./general/views>`: $this->load->view('my_view',
2074 $object);
2075- Added getwhere function to :doc:`Active Record
2076 class <./database/active_record>`.
2077- Added count_all function to :doc:`Active Record
2078 class <./database/active_record>`.
2079- Added language file for scaffolding and fixed a scaffolding bug that
2080 occurs when there are no rows in the specified table.
2081- Added :doc:`$this->db->last_query() <./database/queries>`, which
2082 allows you to view your last query that was run.
2083- Added a new mime type to the upload class for better compatibility.
2084- Changed how cache files are read to prevent PHP errors if the cache
2085 file contains an XML tag, which PHP wants to interpret as a short
2086 tag.
2087- Fixed a bug in a couple of the active record functions (where and
2088 orderby).
2089- Fixed a bug in the image library when realpath() returns false.

2094
2095Version 1.3
2096===========
2097
2098Release Date: April 3, 2006
2099
2100- Added support for :doc:`Models <general/models>`.
2101- Redesigned the database libraries to support additional RDBMs
2102 (Postgres, MySQLi, etc.).
2103- Redesigned the :doc:`Active Record class <./database/active_record>`
2104 to enable more varied types of queries with simpler syntax, and
2105 advanced features like JOINs.
2106- Added a feature to the database class that lets you run :doc:`custom
2107 function calls <./database/call_function>`.
2108- Added support for :doc:`private functions <general/controllers>` in your
2109 controllers. Any controller function name that starts with an
2110 underscore will not be served by a URI request.
2111- Added the ability to pass your own initialization parameters to your
2112 :doc:`custom core libraries <general/creating_libraries>` when using
2113 $this->load->library()
2114- Added support for running standard :doc:`query string URLs <general/urls>`.
2115 These can be optionally enabled in your config file.
2116- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
2117 appended to your URLs. For example, you could add .html to your URLs,
2118 making them appear static. This feature is enabled in your config
2119 file.
2120- Added a new error template for use with native PHP errors.
2121- Added "alternator" function in the :doc:`string
2122 helpers <./helpers/string_helper>`.
2123- Removed slashing from the input class. After much debate we decided
2124 to kill this feature.
2125- Change the commenting style in the scripts to the PEAR standard so
2126 that IDEs and tools like phpDocumenter can harvest the comments.
2127- Added better class and function name-spacing to avoid collisions with
2128 user developed classes. All CodeIgniter classes are now prefixed with
2129 CI\_ and all controller methods are prefixed with _ci to avoid
2130 controller collisions. A list of reserved function names can be
2131 :doc:`found here <general/controllers>`.
2132- Redesigned how the "CI" super object is referenced, depending on
2133 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2134 way to manage objects that utilizes a bit less resources.
2135- Deprecated: $this->db->use_table() has been deprecated. Please read
2136 the :doc:`Active Record <./database/active_record>` page for
2137 information.
2138- Deprecated: $this->db->smart_escape_str() has been deprecated.
2139 Please use this instead: $this->db->escape()
2140- Fixed a bug in the exception handler which was preventing some PHP
2141 errors from showing up.
2142- Fixed a typo in the URI class. $this->total_segment() should be
2143 plural: $this->total_segments()
2144- Fixed some typos in the default calendar template
2145- Fixed some typos in the user guide
2146

2150Release Date: March 21, 2006
2151
2152- Redesigned some internal aspects of the framework to resolve scoping
2153 problems that surfaced during the beta tests. The problem was most
2154 notable when instantiating classes in your constructors, particularly
2155 if those classes in turn did work in their constructors.
2156- Added a global function named
2157 :doc:`get_instance() <general/ancillary_classes>` allowing the main
2158 CodeIgniter object to be accessible throughout your own classes.
2159- Added new :doc:`File Helper <./helpers/file_helper>`:
2160 delete_files()
2161- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2162 index_page()
2163- Added the ability to create your own :doc:`core
2164 libraries <general/creating_libraries>` and store them in your local
2165 application directory.
2166- Added an overwrite option to the :doc:`Upload
2167 class <./libraries/file_uploading>`, enabling files to be
2168 overwritten rather than having the file name appended.
2169- Added Javascript Calendar plugin.
2170- Added search feature to user guide. Note: This is done using Google,
2171 which at the time of this writing has not crawled all the pages of
2172 the docs.
2173- Updated the parser class so that it allows tag pars within other tag
2174 pairs.
2175- Fixed a bug in the DB "where" function.
2176- Fixed a bug that was preventing custom config files to be
2177 auto-loaded.

2189 applications <general/managing_apps>` that share a common CodeIgniter
2190 backend.
2191- Moved the "uri protocol" variable from the index.php file into the
2192 config.php file
2193- Fixed a problem that was preventing certain function calls from
2194 working within constructors.
2195- Fixed a problem that was preventing the $this->load->library function
2196 from working in constructors.

2202- Fixed a bug that was preventing the xss_clean function from being
2203 called from the validation class.
