381Version 2.0.3
382=============
383
384Release Date: August 20, 2011
385
386- Security
387
388 - An improvement was made to the MySQL and MySQLi drivers to prevent
389 exposing a potential vector for SQL injection on sites using
390 multi-byte character sets in the database client connection.
391 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
392 *mysql_set_charset()* creates a situation where using multi-byte
393 character sets on these environments may potentially expose a SQL
394 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
395 character sets are unaffected on all environments.
396
397 If you are running or considering running a multi-byte character
398 set for your database connection, please pay close attention to
399 the server environment you are deploying on to ensure you are not
400 vulnerable.

468 for mysql and mysqli drivers would default to NULL instead of NOT
469 NULL as the docs suggest.
470- Fixed a bug where using $this->db->select_max(),
471 $this->db->select_min(), etc could throw notices. Thanks to w43l for
472 the patch.
473- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
474 whole is more reliable. This should get parameters in crontab
475 working.

594 - Scaffolding, having been deprecated for a number of versions, has
595 been removed.
596 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
597 has been converted to a Helper and
598 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
599 calendar plugin was removed due to the ready availability of great
600 JavaScript calendars, particularly with jQuery.

614 controller sub-directory can be specified when running _GET
615 strings instead of URI segments.
616 - Added ability to set "Package" paths - specific paths where the
617 Loader and Config classes should try to look first for a requested
618 file. This allows distribution of sub-applications with their own
619 libraries, models, config files, etc. in a single "package"
620 directory. See the :doc:`Loader class <libraries/loader>`
621 documentation for more details.
622 - In-development code is now hosted at

Derek Jones8ede1a22011-10-05 13:34:52 -0500628 now be set without an extension, the extension will be taken from
629 the uploaded file instead of the given name.
630 - In :doc:`Database Forge <database/forge>` the name can be omitted
631 from $this->dbforge->modify_column()'s 2nd param if you aren't
632 changing the name.

658 that one can specify the object to look for requested methods,
659 instead of assuming it is in the $CI superobject.
660 - Added "is_object" into the list of unit tests capable of being
661 run.
662 - Table library will generate an empty cell with a blank string, or
663 NULL value.

687 preceding trail of empty folders when creating a Zip archive. This
688 example would contain a zip with "directory" and all of its
689 contents.
690 - Added ability in the Image Library to handle PNG transparency for
691 resize operations when using the GD lib.
692 - Modified the Session class to prevent use if no encryption key is

753 by default so as to encourage responsible use (this function can
754 cause server performance issues when used without caution).

784
785 - Added an optional second parameter to show_404() to disable
786 logging.
787 - Updated loader to automatically apply the sub-class prefix as an

1114- Libraries
1115
1116 - Added a new :doc:`Form Validation
1117 Class <libraries/form_validation>`. It simplifies setting
1118 rules and field names, supports arrays as field names, allows
1119 groups of validation rules to be saved in a config file, and adds
1120 some helper functions for use in view files. **Please note that
1121 the old Validation class is now deprecated**. We will leave it in
1122 the library folder for some time so that existing applications
1123 that use it will not break, but you are encouraged to migrate to
1124 the new version.
1125 - Updated the :doc:`Sessions class <libraries/sessions>` so that
1126 any custom data being saved gets stored to a database rather than
1127 the session cookie (assuming you are using a database to store
1128 session data), permitting much more data to be saved.
1129 - Added the ability to store libraries in subdirectories within
1130 either the main "libraries" or the local application "libraries"
1131 folder. Please see the :doc:`Loader class <libraries/loader>` for
1132 more info.

1137 class <general/profiling>` and support for multiple database
1138 connections.

1141 Class <libraries/typography>`.
1142 - Improved performance and accuracy of xss_clean(), including
1143 reduction of false positives on image/file tests.

1145 multiple calls to the parse() function. The output of each is
1146 appended in the output.

1148 :doc:`File Upload Class <libraries/file_uploading>`.
1149 - Added set_status_header() function to :doc:`Output
1150 class <libraries/output>`.
1151 - Modified :doc:`Pagination <libraries/pagination>` class to only

1153 shown.
1154 - Added support for mb_strlen in the :doc:`Form
1155 Validation <libraries/form_validation>` class so that
1156 multi-byte languages will calculate string lengths properly.
1157
1158- Database
1159
1160 - Improved Active Record class to allow full path column and table
1161 names: hostname.database.table.column. Also improved the alias
1162 handling.
1163 - Improved how table and column names are escaped and prefixed. It
1164 now honors full path names when adding prefixes and escaping.
1165 - Added Active Record caching feature to "update" and "delete"
1166 functions.
1167 - Added removal of non-printing control characters in escape_str()
1168 of DB drivers that do not have native PHP escaping mechanisms
1169 (mssql, oci8, odbc), to avoid potential SQL errors, and possible
1170 sources of SQL injection.
1171 - Added port support to MySQL, MySQLi, and MS SQL database drivers.
1172 - Added driver name variable in each DB driver, based on bug report
1173 #4436.
1174
1175- Helpers
1176
1177 - Added several new "setting" functions to the :doc:`Form
1178 helper <helpers/form_helper>` that allow POST data to be
1179 retrieved and set into forms. These are intended to be used on
1180 their own, or with the new :doc:`Form Validation
1181 Class <libraries/form_validation>`.
1182 - Added current_url() and uri_segments() to :doc:`URL
1183 helper <helpers/url_helper>`.
1184 - Altered auto_link() in the :doc:`URL
1185 helper <helpers/url_helper>` so that email addresses with
1186 "+" included will be linked.
1187 - Added meta() function to :doc:`HTML
1188 helper <helpers/html_helper>`.
1189 - Improved accuracy of calculations in :doc:`Number
1190 helper <helpers/number_helper>`.

1194 helper <helpers/date_helper>` function human_to_unix(),
1195 and eliminated the POSIX regex.

1197 world's current time zones and offsets.
1198 - Modified url_title() in the :doc:`URL
1199 helper <helpers/url_helper>` to remove characters and digits
1200 that are part of character entities, to allow dashes, underscores,
1201 and periods regardless of the $separator, and to allow uppercase
1202 characters.
1203 - Added support for arbitrary attributes in anchor_popup() of the
1204 :doc:`URL helper <helpers/url_helper>`.
1205
1206- Other Changes
1207
1208 - Added :doc:`PHP Style Guide <./general/styleguide>` to docs.
1209 - Added sanitization in xss_clean() for a deprecated HTML tag that
1210 could be abused in user input in Internet Explorer.
1211 - Added a few openxml document mime types, and an additional mobile
1212 agent to mimes.php and user_agents.php respectively.
1213 - Added a file lock check during caching, before trying to write to
1214 the file.
1215 - Modified Cookie key cleaning to unset a few troublesome key names
1216 that can be present in certain environments, preventing CI from
1217 halting execution.
1218 - Changed the output of the profiler to use style attribute rather
1219 than clear, and added the id "codeigniter_profiler" to the
1220 container div.

2131 problems.
2132- Fixed an oversight in the cookie helper in which the config file
2133 cookie settings were not being honored.

2139 for legacy users, but it is recommended that you create your own
2140 :doc:`libraries <./general/libraries>` or

2237
2238Version 1.3.3
2239=============
2240
2241Release Date: June 1, 2006
2242
2243- Models do **not** connect automatically to the database as of this
2244 version. :doc:`More info here <./general/models>`.
2245- Updated the Sessions class to utilize the active record class when
2246 running session related queries. Previously the queries assumed MySQL
2247 syntax.
2248- Updated alternator() function to re-initialize when called with no
2249 arguments, allowing multiple calls.
2250- Fixed a bug in the active record "having" function.
2251- Fixed a problem in the validation class which was making checkboxes
2252 be ignored when required.
2253- Fixed a bug in the word_limiter() helper function. It was cutting
2254 off the fist word.
2255- Fixed a bug in the xss_clean function due to a PHP bug that affects
2256 some versions of html_entity_decode.
2257- Fixed a validation bug that was preventing rules from being set twice
2258 in one controller.
2259- Fixed a calendar bug that was not letting it use dynamically loaded
2260 languages.
2261- Fixed a bug in the active record class when using WHERE clauses with
2262 LIKE
2263- Fixed a bug in the hash() security helper.
2264- Fixed some typos.
2265
2266Version 1.3.2
2267=============
2268
2269Release Date: April 17, 2006
2270
2271- Changed the behavior of the validation class such that if a
2272 "required" rule is NOT explicitly stated for a field then all other
2273 tests get ignored.
2274- Fixed a bug in the Controller class that was causing it to look in
2275 the local "init" folder instead of the main system one.
2276- Fixed a bug in the init_pagination file. The $config item was not
2277 being set correctly.
2278- Fixed a bug in the auto typography helper that was causing
2279 inconsistent behavior.
2280- Fixed a couple bugs in the Model class.
2281- Fixed some documentation typos and errata.
2282
2283Version 1.3.1
2284=============
2285
2286Release Date: April 11, 2006
2287
2288- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
2289- Added the ability to pass objects to the **insert()** and
2290 **update()** database functions. This feature enables you to (among
2291 other things) use your :doc:`Model class <./general/models>`
2292 variables to run queries with. See the Models page for details.
2293- Added the ability to pass objects to the :doc:`view loading
2294 function <./general/views>`: $this->load->view('my_view',
2295 $object);
2296- Added getwhere function to :doc:`Active Record
2297 class <./database/active_record>`.
2298- Added count_all function to :doc:`Active Record
2299 class <./database/active_record>`.
2300- Added language file for scaffolding and fixed a scaffolding bug that
2301 occurs when there are no rows in the specified table.
2302- Added :doc:`$this->db->last_query() <./database/queries>`, which
2303 allows you to view your last query that was run.
2304- Added a new mime type to the upload class for better compatibility.
2305- Changed how cache files are read to prevent PHP errors if the cache
2306 file contains an XML tag, which PHP wants to interpret as a short
2307 tag.
2308- Fixed a bug in a couple of the active record functions (where and
2309 orderby).
2310- Fixed a bug in the image library when realpath() returns false.
2311- Fixed a bug in the Models that was preventing libraries from being
2312 used within them.
2313- Fixed a bug in the "exact_length" function of the validation class.
2314- Fixed some typos in the user guide
2315
2316Version 1.3
2317===========
2318
2319Release Date: April 3, 2006
2320
2321- Added support for :doc:`Models <general/models>`.
2322- Redesigned the database libraries to support additional RDBMs
2323 (Postgres, MySQLi, etc.).
2324- Redesigned the :doc:`Active Record class <./database/active_record>`
2325 to enable more varied types of queries with simpler syntax, and
2326 advanced features like JOINs.
2327- Added a feature to the database class that lets you run :doc:`custom
2328 function calls <./database/call_function>`.
2329- Added support for :doc:`private functions <general/controllers>` in your
2330 controllers. Any controller function name that starts with an
2331 underscore will not be served by a URI request.
2332- Added the ability to pass your own initialization parameters to your
2333 :doc:`custom core libraries <general/creating_libraries>` when using
2334 $this->load->library()
2335- Added support for running standard :doc:`query string URLs <general/urls>`.
2336 These can be optionally enabled in your config file.
2337- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
2338 appended to your URLs. For example, you could add .html to your URLs,
2339 making them appear static. This feature is enabled in your config
2340 file.
2341- Added a new error template for use with native PHP errors.
2342- Added "alternator" function in the :doc:`string
2343 helpers <./helpers/string_helper>`.
2344- Removed slashing from the input class. After much debate we decided
2345 to kill this feature.
2346- Change the commenting style in the scripts to the PEAR standard so
2347 that IDEs and tools like phpDocumenter can harvest the comments.
2348- Added better class and function name-spacing to avoid collisions with
2349 user developed classes. All CodeIgniter classes are now prefixed with
2350 CI\_ and all controller methods are prefixed with _ci to avoid
2351 controller collisions. A list of reserved function names can be
2352 :doc:`found here <general/controllers>`.
2353- Redesigned how the "CI" super object is referenced, depending on
2354 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2355 way to manage objects that utilizes a bit less resources.
2356- Deprecated: $this->db->use_table() has been deprecated. Please read
2357 the :doc:`Active Record <./database/active_record>` page for
2358 information.
2359- Deprecated: $this->db->smart_escape_str() has been deprecated.
2360 Please use this instead: $this->db->escape()
2361- Fixed a bug in the exception handler which was preventing some PHP
2362 errors from showing up.
2363- Fixed a typo in the URI class. $this->total_segment() should be
2364 plural: $this->total_segments()
2365- Fixed some typos in the default calendar template
2366- Fixed some typos in the user guide
2367
2368Version 1.2
2369===========
2370
2371Release Date: March 21, 2006
2372
2373- Redesigned some internal aspects of the framework to resolve scoping
2374 problems that surfaced during the beta tests. The problem was most
2375 notable when instantiating classes in your constructors, particularly
2376 if those classes in turn did work in their constructors.
2377- Added a global function named
2378 :doc:`get_instance() <general/ancillary_classes>` allowing the main
2379 CodeIgniter object to be accessible throughout your own classes.
2380- Added new :doc:`File Helper <./helpers/file_helper>`:
2381 delete_files()
2382- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2383 index_page()
2384- Added the ability to create your own :doc:`core
2385 libraries <general/creating_libraries>` and store them in your local
2386 application directory.
2387- Added an overwrite option to the :doc:`Upload
2388 class <./libraries/file_uploading>`, enabling files to be
2389 overwritten rather than having the file name appended.
2390- Added Javascript Calendar plugin.
2391- Added search feature to user guide. Note: This is done using Google,
2392 which at the time of this writing has not crawled all the pages of
2393 the docs.
2394- Updated the parser class so that it allows tag pars within other tag
2395 pairs.
2396- Fixed a bug in the DB "where" function.
2397- Fixed a bug that was preventing custom config files to be
2398 auto-loaded.
2399- Fixed a bug in the mysql class bind feature that prevented question
2400 marks in the replacement data.
2401- Fixed some bugs in the xss_clean function

2408- Added a :doc:`Calendaring class <./libraries/calendar>`.
2409- Added support for running :doc:`multiple
2410 applications <general/managing_apps>` that share a common CodeIgniter
2411 backend.
2412- Moved the "uri protocol" variable from the index.php file into the
2413 config.php file
2414- Fixed a problem that was preventing certain function calls from
2415 working within constructors.
2416- Fixed a problem that was preventing the $this->load->library function
2417 from working in constructors.
2418- Fixed a bug that occurred when the session class was loaded using the
2419 auto-load routine.
2420- Fixed a bug that can happen with PHP versions that do not support the
2421 E_STRICT constant
2422- Fixed a data type error in the form_radio function (form helper)
2423- Fixed a bug that was preventing the xss_clean function from being
2424 called from the validation class.
2425- Fixed the cookie related config names, which were incorrectly
2426 specified as $conf rather than $config
2427- Fixed a pagination problem in the scaffolding.
2428- Fixed a bug in the mysql class "where" function.
2429- Fixed a regex problem in some code that trimmed duplicate slashes.
2430- Fixed a bug in the br() function in the HTML helper
2431- Fixed a syntax mistake in the form_dropdown function in the Form
2432 Helper.
2433- Removed the "style" attributes form the form helpers.
2434- Updated the documentation. Added "next/previous" links to each page
2435 and fixed various typos.
