167Version 2.0.3
168=============
169
170Release Date: August 20, 2011
171
172- Security
173
174 - An improvement was made to the MySQL and MySQLi drivers to prevent
175 exposing a potential vector for SQL injection on sites using
176 multi-byte character sets in the database client connection.
177 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
178 *mysql_set_charset()* creates a situation where using multi-byte
179 character sets on these environments may potentially expose a SQL
180 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
181 character sets are unaffected on all environments.
182
183 If you are running or considering running a multi-byte character
184 set for your database connection, please pay close attention to
185 the server environment you are deploying on to ensure you are not
186 vulnerable.

227 library <libraries/loader>` to retrieve global vars set with
228 $this->load->view() and $this->load->vars().

230 than escape_str().
231

234
235- Added ENVIRONMENT to reserved constants. (Reactor #196)
236- Changed server check to ensure SCRIPT_NAME is defined. (Reactor #57)

253- Fixed a bug where not setting 'null' when adding fields in db_forge
254 for mysql and mysqli drivers would default to NULL instead of NOT
255 NULL as the docs suggest.
256- Fixed a bug where using $this->db->select_max(),
257 $this->db->select_min(), etc could throw notices. Thanks to w43l for
258 the patch.
259- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
260 whole is more reliable. This should get parameters in crontab
261 working.

406 directory. See the :doc:`Loader class <libraries/loader>`
407 documentation for more details.

894Version 1.7
895===========
896
897Release Date: October 23, 2008
898Hg Tag: 1.7.0
899
900- Libraries
901
902 - Added a new :doc:`Form Validation
903 Class <libraries/form_validation>`. It simplifies setting
904 rules and field names, supports arrays as field names, allows
905 groups of validation rules to be saved in a config file, and adds
906 some helper functions for use in view files. **Please note that
907 the old Validation class is now deprecated**. We will leave it in
908 the library folder for some time so that existing applications
909 that use it will not break, but you are encouraged to migrate to
910 the new version.
911 - Updated the :doc:`Sessions class <libraries/sessions>` so that
912 any custom data being saved gets stored to a database rather than
913 the session cookie (assuming you are using a database to store
914 session data), permitting much more data to be saved.
915 - Added the ability to store libraries in subdirectories within
916 either the main "libraries" or the local application "libraries"
917 folder. Please see the :doc:`Loader class <libraries/loader>` for
918 more info.
919 - Added the ability to assign library objects to your own variable
920 names when you use $this->load->library(). Please see the :doc:`Loader
921 class <libraries/loader>` for more info.
922 - Added controller class/method info to :doc:`Profiler
923 class <general/profiling>` and support for multiple database
924 connections.
925 - Improved the "auto typography" feature and moved it out of the
926 helper into its own :doc:`Typography
927 Class <libraries/typography>`.
928 - Improved performance and accuracy of xss_clean(), including
929 reduction of false positives on image/file tests.
930 - Improved :doc:`Parser class <./libraries/parser>` to allow
931 multiple calls to the parse() function. The output of each is
932 appended in the output.
933 - Added max_filename option to set a file name length limit in the
934 :doc:`File Upload Class <libraries/file_uploading>`.
935 - Added set_status_header() function to :doc:`Output
936 class <libraries/output>`.
937 - Modified :doc:`Pagination <libraries/pagination>` class to only
938 output the "First" link when the link for page one would not be
939 shown.
940 - Added support for mb_strlen in the :doc:`Form
941 Validation <libraries/form_validation>` class so that
942 multi-byte languages will calculate string lengths properly.
943
944- Database
945
946 - Improved Active Record class to allow full path column and table
947 names: hostname.database.table.column. Also improved the alias
948 handling.
949 - Improved how table and column names are escaped and prefixed. It
950 now honors full path names when adding prefixes and escaping.
951 - Added Active Record caching feature to "update" and "delete"
952 functions.
953 - Added removal of non-printing control characters in escape_str()
954 of DB drivers that do not have native PHP escaping mechanisms
955 (mssql, oci8, odbc), to avoid potential SQL errors, and possible
956 sources of SQL injection.
957 - Added port support to MySQL, MySQLi, and MS SQL database drivers.
958 - Added driver name variable in each DB driver, based on bug report
959 #4436.
960
961- Helpers
962
963 - Added several new "setting" functions to the :doc:`Form
964 helper <helpers/form_helper>` that allow POST data to be
965 retrieved and set into forms. These are intended to be used on
966 their own, or with the new :doc:`Form Validation
967 Class <libraries/form_validation>`.
968 - Added current_url() and uri_segments() to :doc:`URL
969 helper <helpers/url_helper>`.
970 - Altered auto_link() in the :doc:`URL
971 helper <helpers/url_helper>` so that email addresses with
972 "+" included will be linked.
973 - Added meta() function to :doc:`HTML
974 helper <helpers/html_helper>`.
975 - Improved accuracy of calculations in :doc:`Number
976 helper <helpers/number_helper>`.
977 - Removed added newlines ("\\n") from most form and html helper
978 functions.
979 - Tightened up validation in the :doc:`Date
980 helper <helpers/date_helper>` function human_to_unix(),
981 and eliminated the POSIX regex.
982 - Updated :doc:`Date helper <helpers/date_helper>` to match the
983 world's current time zones and offsets.
984 - Modified url_title() in the :doc:`URL
985 helper <helpers/url_helper>` to remove characters and digits
986 that are part of character entities, to allow dashes, underscores,
987 and periods regardless of the $separator, and to allow uppercase
988 characters.
989 - Added support for arbitrary attributes in anchor_popup() of the
990 :doc:`URL helper <helpers/url_helper>`.
991
992- Other Changes
993
994 - Added :doc:`PHP Style Guide <./general/styleguide>` to docs.
995 - Added sanitization in xss_clean() for a deprecated HTML tag that
996 could be abused in user input in Internet Explorer.
997 - Added a few openxml document mime types, and an additional mobile
998 agent to mimes.php and user_agents.php respectively.
999 - Added a file lock check during caching, before trying to write to
1000 the file.
1001 - Modified Cookie key cleaning to unset a few troublesome key names
1002 that can be present in certain environments, preventing CI from
1003 halting execution.
1004 - Changed the output of the profiler to use style attribute rather
1005 than clear, and added the id "codeigniter_profiler" to the
1006 container div.

1815- Added :doc:`$query->list_fields() <./database/fields>` function to
1816 database class

1822 Helper <./helpers/html_helper>`
1823- Added the ability to rewrite :doc:`short
1824 tags <./general/alternative_php>` on-the-fly, converting them
1825 to standard PHP statements, for those servers that do not support
1826 short tags. This allows the cleaner syntax to be used regardless of
1827 whether it's supported by the server.
1828- Added the ability to :doc:`rename or relocate the "application"
1829 folder <./general/managing_apps>`.
1830- Added more thorough initialization in the upload class so that all
1831 class variables are reset.
1832- Added "is_numeric" to validation, which uses the native PHP
1833 is_numeric function.
1834- Improved the URI handler to make it more reliable when the
1835 $config['uri_protocol'] item is set to AUTO.
1836- Moved most of the functions in the Controller class into the Loader
1837 class, allowing fewer reserved function names for controllers when
1838 running under PHP 5.
1839- Updated the DB Result class to return an empty array when
1840 $query->result() doesn't produce a result.
1841- Updated the input->cookie() and input->post() functions in :doc:`Input

1843 that are arrays to be run through the XSS filter.
1844- Documented three functions from the Validation
1845 class that were missing from the user
1846 guide: set_select(), set_radio(), and set_checkbox().

1854 entities.
1855- Fixed a bug that affects some versions of PHP when output buffering
1856 is nested.
1857- Fixed a bug that caused CI to stop working when the PHP magic
1858 __get() or __set() functions were used within models or
1859 controllers.
1860- Fixed a pagination bug that was permitting negative values in the
1861 URL.
1862- Fixed an oversight in which the Loader class was not allowed to be
1863 extended.
1864- Changed _get_config() to get_config() since the function is not a
1865 private one.
1866- **Deprecated "init" folder**. Initialization happens automatically
1867 now. :doc:`Please see documentation <./general/creating_libraries>`.
1868- **Deprecated** $this->db->field_names() USE
1869 $this->db->list_fields()
1870- **Deprecated** the $config['log_errors'] item from the config.php
1871 file. Instead, $config['log_threshold'] can be set to "0" to turn it
1872 off.

1874Version 1.4.1
1875=============
1876
1877Release Date: September 21, 2006
1878
1879- Added a new feature that passes URI segments directly to your
1880 function calls as parameters. See the
1881 :doc:`Controllers <general/controllers>` page for more info.
1882- Added support for a function named _output(), which when used in
1883 your controllers will received the final rendered output from the
1884 output class. More info in the :doc:`Controllers <general/controllers>`
1885 page.
1886- Added several new functions in the :doc:`URI
1887 Class <./libraries/uri>` to let you retrieve and manipulate URI
1888 segments that have been re-routed using the :doc:`URI
1889 Routing <general/routing>` feature. Previously, the URI class did not
1890 permit you to access any re-routed URI segments, but now it does.
1891- Added :doc:`$this->output->set_header() <./libraries/output>`
1892 function, which allows you to set server headers.
1893- Updated plugins, helpers, and language classes to allow your
1894 application folder to contain its own plugins, helpers, and language
1895 folders. Previously they were always treated as global for your
1896 entire installation. If your application folder contains any of these
1897 resources they will be used *instead* the global ones.
1898- Added :doc:`Inflector helper <./helpers/inflector_helper>`.
1899- Added element() function in the :doc:`array
1900 helper <./helpers/array_helper>`.
1901- Added RAND() to active record orderby() function.
1902- Added delete_cookie() and get_cookie() to :doc:`Cookie
1903 helper <./helpers/cookie_helper>`, even though the input class
1904 has a cookie fetching function.
1905- Added Oracle database driver (still undergoing testing so it might
1906 have some bugs).
1907- Added the ability to combine pseudo-variables and php variables in
1908 the template parser class.
1909- Added output compression option to the config file.
1910- Removed the is_numeric test from the db->escape() function.
1911- Fixed a MySQLi bug that was causing error messages not to contain
1912 proper error data.
1913- Fixed a bug in the email class which was causing it to ignore
1914 explicitly set alternative headers.
1915- Fixed a bug that was causing a PHP error when the Exceptions class
1916 was called within the get_config() function since it was causing
1917 problems.
1918- Fixed an oversight in the cookie helper in which the config file
1919 cookie settings were not being honored.
1920- Fixed an oversight in the upload class. An item mentioned in the 1.4
1921 changelog was missing.
1922- Added some code to allow email attachments to be reset when sending
1923 batches of email.
1924- Deprecated the application/scripts folder. It will continue to work
1925 for legacy users, but it is recommended that you create your own
1926 :doc:`libraries <./general/libraries>` or
1927 :doc:`models <./general/models>` instead. It was originally added
1928 before CI had user libraries or models, but it's not needed anymore.
1929- Deprecated the $autoload['core'] item from the autoload.php file.
1930 Instead, please now use: $autoload['libraries']
1931- Deprecated the following database functions:
1932 $this->db->smart_escape_str() and $this->db->fields().

1939- Added :doc:`Hooks <./general/hooks>` feature, enabling you to tap
1940 into and modify the inner workings of the framework without hacking
1941 the core files.
1942- Added the ability to organize controller files :doc:`into
1943 sub-folders <general/controllers>`. Kudos to Marco for
1944 `suggesting <http://codeigniter.com/forums/viewthread/627/>`_ this
1945 (and the next two) feature.
kenjis087a7a82011-10-20 20:08:47 +09001946- Added regular expressions support for :doc:`routing

1956 helper.
1957- Added support for changing the port number in the :doc:`Postgres
1958 driver <./database/configuration>`.
1959- Moved the list of "allowed URI characters" out of the Router class
1960 and into the config file.
1961- Moved the MIME type array out of the Upload class and into its own
1962 file in the applications/config/ folder.
1963- Updated the Upload class to allow the upload field name to be set
1964 when calling :doc:`do_upload() <./libraries/file_uploading>`.
1965- Updated the :doc:`Config Library <./libraries/config>` to be able to
1966 load config files silently, and to be able to assign config files to
1967 their own index (to avoid collisions if you use multiple config
1968 files).
1969- Updated the URI Protocol code to allow more options so that URLs will
1970 work more reliably in different environments.
1971- Updated the form_open() helper to allow the GET method to be used.
1972- Updated the MySQLi execute() function with some code to help prevent
1973 lost connection errors.
1974- Updated the SQLite Driver to check for object support before
1975 attempting to return results as objects. If unsupported it returns an
1976 array.
1977- Updated the Models loader function to allow multiple loads of the
1978 same model.
1979- Updated the MS SQL driver so that single quotes are escaped.

1984 compatibility.
1985- Removed backticks from Postgres class since these are not needed.
1986- Renamed display() to _display() in the Output class to make it clear
1987 that it's a private function.
1988- Deprecated the hash() function due to a naming conflict with a native
1989 PHP function with the same name. Please use dohash() instead.
1990- Fixed an bug that was preventing the input class from unsetting GET
1991 variables.
1992- Fixed a router bug that was making it too greedy when matching end
1993 segments.

1995- Fixed a bug in which loading a language file was producing a "file
1996 contains no data" message.
1997- Fixed a session bug caused by the XSS Filtering feature inadvertently
1998 changing the case of certain words.
1999- Fixed some missing prefixes when using the database prefix feature.

2028
2029- Models do **not** connect automatically to the database as of this
2030 version. :doc:`More info here <./general/models>`.
2031- Updated the Sessions class to utilize the active record class when
2032 running session related queries. Previously the queries assumed MySQL
2033 syntax.

2035 arguments, allowing multiple calls.
2036- Fixed a bug in the active record "having" function.
2037- Fixed a problem in the validation class which was making checkboxes
2038 be ignored when required.

2042 some versions of html_entity_decode.
2043- Fixed a validation bug that was preventing rules from being set twice
2044 in one controller.

2053=============
2054
2055Release Date: April 17, 2006
2056
2057- Changed the behavior of the validation class such that if a
2058 "required" rule is NOT explicitly stated for a field then all other
2059 tests get ignored.
2060- Fixed a bug in the Controller class that was causing it to look in
2061 the local "init" folder instead of the main system one.
2062- Fixed a bug in the init_pagination file. The $config item was not
2063 being set correctly.

2074- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
2075- Added the ability to pass objects to the **insert()** and
2076 **update()** database functions. This feature enables you to (among
2077 other things) use your :doc:`Model class <./general/models>`
2078 variables to run queries with. See the Models page for details.
2079- Added the ability to pass objects to the :doc:`view loading
2080 function <./general/views>`: $this->load->view('my_view',
2081 $object);
2082- Added getwhere function to :doc:`Active Record
2083 class <./database/active_record>`.
2084- Added count_all function to :doc:`Active Record
2085 class <./database/active_record>`.
2086- Added language file for scaffolding and fixed a scaffolding bug that
2087 occurs when there are no rows in the specified table.
2088- Added :doc:`$this->db->last_query() <./database/queries>`, which
2089 allows you to view your last query that was run.
2090- Added a new mime type to the upload class for better compatibility.
2091- Changed how cache files are read to prevent PHP errors if the cache
2092 file contains an XML tag, which PHP wants to interpret as a short
2093 tag.
2094- Fixed a bug in a couple of the active record functions (where and
2095 orderby).
2096- Fixed a bug in the image library when realpath() returns false.

2101
2102Version 1.3
2103===========
2104
2105Release Date: April 3, 2006
2106
2107- Added support for :doc:`Models <general/models>`.
2108- Redesigned the database libraries to support additional RDBMs
2109 (Postgres, MySQLi, etc.).
2110- Redesigned the :doc:`Active Record class <./database/active_record>`
2111 to enable more varied types of queries with simpler syntax, and
2112 advanced features like JOINs.
2113- Added a feature to the database class that lets you run :doc:`custom
2114 function calls <./database/call_function>`.
2115- Added support for :doc:`private functions <general/controllers>` in your
2116 controllers. Any controller function name that starts with an
2117 underscore will not be served by a URI request.
2118- Added the ability to pass your own initialization parameters to your
2119 :doc:`custom core libraries <general/creating_libraries>` when using
2120 $this->load->library()
2121- Added support for running standard :doc:`query string URLs <general/urls>`.
2122 These can be optionally enabled in your config file.
2123- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
2124 appended to your URLs. For example, you could add .html to your URLs,
2125 making them appear static. This feature is enabled in your config
2126 file.
2127- Added a new error template for use with native PHP errors.
2128- Added "alternator" function in the :doc:`string
2129 helpers <./helpers/string_helper>`.
2130- Removed slashing from the input class. After much debate we decided
2131 to kill this feature.
2132- Change the commenting style in the scripts to the PEAR standard so
2133 that IDEs and tools like phpDocumenter can harvest the comments.
2134- Added better class and function name-spacing to avoid collisions with
2135 user developed classes. All CodeIgniter classes are now prefixed with
2136 CI\_ and all controller methods are prefixed with _ci to avoid
2137 controller collisions. A list of reserved function names can be
2138 :doc:`found here <general/controllers>`.
2139- Redesigned how the "CI" super object is referenced, depending on
2140 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2141 way to manage objects that utilizes a bit less resources.
2142- Deprecated: $this->db->use_table() has been deprecated. Please read
2143 the :doc:`Active Record <./database/active_record>` page for
2144 information.
2145- Deprecated: $this->db->smart_escape_str() has been deprecated.
2146 Please use this instead: $this->db->escape()
2147- Fixed a bug in the exception handler which was preventing some PHP
2148 errors from showing up.
2149- Fixed a typo in the URI class. $this->total_segment() should be
2150 plural: $this->total_segments()
2151- Fixed some typos in the default calendar template
2152- Fixed some typos in the user guide
2153

2157Release Date: March 21, 2006
2158
2159- Redesigned some internal aspects of the framework to resolve scoping
2160 problems that surfaced during the beta tests. The problem was most
2161 notable when instantiating classes in your constructors, particularly
2162 if those classes in turn did work in their constructors.
2163- Added a global function named
2164 :doc:`get_instance() <general/ancillary_classes>` allowing the main
2165 CodeIgniter object to be accessible throughout your own classes.
2166- Added new :doc:`File Helper <./helpers/file_helper>`:
2167 delete_files()
2168- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2169 index_page()
2170- Added the ability to create your own :doc:`core
2171 libraries <general/creating_libraries>` and store them in your local
2172 application directory.
2173- Added an overwrite option to the :doc:`Upload
2174 class <./libraries/file_uploading>`, enabling files to be
2175 overwritten rather than having the file name appended.
2176- Added Javascript Calendar plugin.
2177- Added search feature to user guide. Note: This is done using Google,
2178 which at the time of this writing has not crawled all the pages of
2179 the docs.
2180- Updated the parser class so that it allows tag pars within other tag
2181 pairs.
2182- Fixed a bug in the DB "where" function.
2183- Fixed a bug that was preventing custom config files to be
2184 auto-loaded.

2196 applications <general/managing_apps>` that share a common CodeIgniter
2197 backend.
2198- Moved the "uri protocol" variable from the index.php file into the
2199 config.php file
2200- Fixed a problem that was preventing certain function calls from
2201 working within constructors.
2202- Fixed a problem that was preventing the $this->load->library function
2203 from working in constructors.
2204- Fixed a bug that occurred when the session class was loaded using the
2205 auto-load routine.

2207 E_STRICT constant
2208- Fixed a data type error in the form_radio function (form helper)
2209- Fixed a bug that was preventing the xss_clean function from being
2210 called from the validation class.
