334-------------------
335
Andrey Andreevec902162012-07-02 15:57:34 +0300336- Fixed a bug (#697) - A wrong array key was used in the :doc:`File Uploading Library <libraries/file_uploading>` to check for mime-types.
337- Fixed a bug - ``form_open()`` compared $action against ``site_url()`` instead of ``base_url()``.
338- Fixed a bug - ``CI_Upload::_file_mime_type()`` could've failed if ``mime_content_type()`` is used for the detection and returns FALSE.
Phil Sturgeon6b414d12012-02-29 11:59:35 +0000339- Fixed a bug (#538) - Windows paths were ignored when using the :doc:`Image Manipulation Library <libraries/image_lib>` to create a new file.
Andrey Andreev67a08ed2012-05-19 13:35:40 +0300340- Fixed a bug - When database caching was enabled, $this->db->query() checked the cache before binding variables which resulted in cached queries never being found.
341- Fixed a bug - CSRF cookie value was allowed to be any (non-empty) string before being written to the output, making code injection a risk.
342- Fixed a bug (#726) - PDO put a 'dbname' argument in it's connection string regardless of the database platform in use, which made it impossible to use SQLite.
Andrey Andreevec902162012-07-02 15:57:34 +0300343- Fixed a bug - ``CI_DB_pdo_driver::num_rows()`` was not returning properly value with SELECT queries, cause it was relying on ``PDOStatement::rowCount()``.
344- Fixed a bug (#1059) - ``CI_Image_lib::clear()`` was not correctly clearing all necessary object properties, namely width and height.

443Version 2.0.3
444=============
445
446Release Date: August 20, 2011
447
448- Security
449
450 - An improvement was made to the MySQL and MySQLi drivers to prevent
451 exposing a potential vector for SQL injection on sites using
452 multi-byte character sets in the database client connection.
453 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
454 *mysql_set_charset()* creates a situation where using multi-byte
455 character sets on these environments may potentially expose a SQL
456 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
457 character sets are unaffected on all environments.
458
459 If you are running or considering running a multi-byte character
460 set for your database connection, please pay close attention to
461 the server environment you are deploying on to ensure you are not
462 vulnerable.
463

476 Thanks to epallerols for the patch.
477 - Added "application/x-csv" to mimes.php.
Timothy Warren01b56bc2011-10-10 10:45:45 -0400478 - Fixed a bug where :doc:`Email library <libraries/email>`
Derek Jones8ede1a22011-10-05 13:34:52 -0500479 attachments with a "." in the name would using invalid MIME-types.
Derek Jones8ede1a22011-10-05 13:34:52 -0500480
481- Helpers
482
483 - Added an optional third parameter to heading() which allows adding
484 html attributes to the rendered heading tag.
485 - form_open() now only adds a hidden (Cross-site Reference Forgery)
486 protection field when the form's action is internal and is set to
487 the post method. (Reactor #165)

489 helper <helpers/inflector_helper>` to support considerably
490 more words.
491

493
494 - Altered Session to use a longer match against the user_agent

497 Driver <database/queries>`.
498 - Changed $this->cart->insert() in the :doc:`Cart

500 item was inserted successfully.
501 - Added $this->load->get_var() to the :doc:`Loader
502 library <libraries/loader>` to retrieve global vars set with
503 $this->load->view() and $this->load->vars().
504 - Changed $this->db->having() to insert quotes using escape() rather
505 than escape_str().
506

509
510- Added ENVIRONMENT to reserved constants. (Reactor #196)
511- Changed server check to ensure SCRIPT_NAME is defined. (Reactor #57)
512- Removed APPPATH.'third_party' from the packages autoloader to negate

527 of all items in the cart instead of your total count.
528- Fixed a bug where not setting 'null' when adding fields in db_forge
529 for mysql and mysqli drivers would default to NULL instead of NOT
530 NULL as the docs suggest.
531- Fixed a bug where using $this->db->select_max(),
532 $this->db->select_min(), etc could throw notices. Thanks to w43l for
533 the patch.
534- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
535 whole is more reliable. This should get parameters in crontab
536 working.

649Release Date: January 28, 2011
650Hg Tag: v2.0.0
651
652- General changes
653
654 - PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.
655 - Scaffolding, having been deprecated for a number of versions, has
656 been removed.
657 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
658 has been converted to a Helper and
659 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
660 calendar plugin was removed due to the ready availability of great
661 JavaScript calendars, particularly with jQuery.
662 - Added new special Library type:
663 :doc:`Drivers <./general/drivers>`.
664 - Added full query-string support. See the config file for details.
665 - Moved the application folder outside of the system folder.
666 - Moved system/cache and system/logs directories to the application
667 directory.
668 - Added routing overrides to the main index.php file, enabling the
669 normal routing to be overridden on a per "index" file basis.
670 - Added the ability to set config values (or override config values)
671 directly from data set in the main index.php file. This allows a
672 single application to be used with multiple front controllers,
673 each having its own config values.
674 - Added $config['directory_trigger'] to the config file so that a
675 controller sub-directory can be specified when running _GET
676 strings instead of URI segments.
677 - Added ability to set "Package" paths - specific paths where the
678 Loader and Config classes should try to look first for a requested
679 file. This allows distribution of sub-applications with their own
680 libraries, models, config files, etc. in a single "package"
681 directory. See the :doc:`Loader class <libraries/loader>`
682 documentation for more details.
683 - In-development code is now hosted at
684 `BitBucket <http://bitbucket.org/ellislab/codeigniter-reactor/>`_.

1177 - Added a new :doc:`Form Validation
1178 Class <libraries/form_validation>`. It simplifies setting
1179 rules and field names, supports arrays as field names, allows
1180 groups of validation rules to be saved in a config file, and adds
1181 some helper functions for use in view files. **Please note that
1182 the old Validation class is now deprecated**. We will leave it in
1183 the library folder for some time so that existing applications
1184 that use it will not break, but you are encouraged to migrate to
1185 the new version.
1186 - Updated the :doc:`Sessions class <libraries/sessions>` so that
1187 any custom data being saved gets stored to a database rather than
1188 the session cookie (assuming you are using a database to store
1189 session data), permitting much more data to be saved.
1190 - Added the ability to store libraries in subdirectories within
1191 either the main "libraries" or the local application "libraries"
1192 folder. Please see the :doc:`Loader class <libraries/loader>` for
1193 more info.
1194 - Added the ability to assign library objects to your own variable
1195 names when you use $this->load->library(). Please see the :doc:`Loader
1196 class <libraries/loader>` for more info.
1197 - Added controller class/method info to :doc:`Profiler
1198 class <general/profiling>` and support for multiple database
1199 connections.
1200 - Improved the "auto typography" feature and moved it out of the
1201 helper into its own :doc:`Typography
1202 Class <libraries/typography>`.
1203 - Improved performance and accuracy of xss_clean(), including
1204 reduction of false positives on image/file tests.
1205 - Improved :doc:`Parser class <./libraries/parser>` to allow
1206 multiple calls to the parse() function. The output of each is
1207 appended in the output.
1208 - Added max_filename option to set a file name length limit in the
1209 :doc:`File Upload Class <libraries/file_uploading>`.
1210 - Added set_status_header() function to :doc:`Output
1211 class <libraries/output>`.
1212 - Modified :doc:`Pagination <libraries/pagination>` class to only
1213 output the "First" link when the link for page one would not be
1214 shown.
1215 - Added support for mb_strlen in the :doc:`Form
1216 Validation <libraries/form_validation>` class so that
1217 multi-byte languages will calculate string lengths properly.
1218
1219- Database
1220
1221 - Improved Active Record class to allow full path column and table
1222 names: hostname.database.table.column. Also improved the alias
1223 handling.
1224 - Improved how table and column names are escaped and prefixed. It
1225 now honors full path names when adding prefixes and escaping.
1226 - Added Active Record caching feature to "update" and "delete"
1227 functions.
1228 - Added removal of non-printing control characters in escape_str()
1229 of DB drivers that do not have native PHP escaping mechanisms
1230 (mssql, oci8, odbc), to avoid potential SQL errors, and possible
1231 sources of SQL injection.
1232 - Added port support to MySQL, MySQLi, and MS SQL database drivers.
1233 - Added driver name variable in each DB driver, based on bug report
1234 #4436.
1235
1236- Helpers
1237
1238 - Added several new "setting" functions to the :doc:`Form
1239 helper <helpers/form_helper>` that allow POST data to be
1240 retrieved and set into forms. These are intended to be used on
1241 their own, or with the new :doc:`Form Validation
1242 Class <libraries/form_validation>`.
1243 - Added current_url() and uri_segments() to :doc:`URL
1244 helper <helpers/url_helper>`.
1245 - Altered auto_link() in the :doc:`URL
1246 helper <helpers/url_helper>` so that email addresses with
1247 "+" included will be linked.
1248 - Added meta() function to :doc:`HTML
1249 helper <helpers/html_helper>`.
1250 - Improved accuracy of calculations in :doc:`Number
1251 helper <helpers/number_helper>`.
1252 - Removed added newlines ("\\n") from most form and html helper
1253 functions.
1254 - Tightened up validation in the :doc:`Date
1255 helper <helpers/date_helper>` function human_to_unix(),
1256 and eliminated the POSIX regex.
1257 - Updated :doc:`Date helper <helpers/date_helper>` to match the
1258 world's current time zones and offsets.
1259 - Modified url_title() in the :doc:`URL
1260 helper <helpers/url_helper>` to remove characters and digits
1261 that are part of character entities, to allow dashes, underscores,
1262 and periods regardless of the $separator, and to allow uppercase
1263 characters.
1264 - Added support for arbitrary attributes in anchor_popup() of the
1265 :doc:`URL helper <helpers/url_helper>`.
1266
1267- Other Changes
1268
1269 - Added :doc:`PHP Style Guide <./general/styleguide>` to docs.
1270 - Added sanitization in xss_clean() for a deprecated HTML tag that
1271 could be abused in user input in Internet Explorer.
1272 - Added a few openxml document mime types, and an additional mobile
1273 agent to mimes.php and user_agents.php respectively.
1274 - Added a file lock check during caching, before trying to write to
1275 the file.
1276 - Modified Cookie key cleaning to unset a few troublesome key names
1277 that can be present in certain environments, preventing CI from
1278 halting execution.
1279 - Changed the output of the profiler to use style attribute rather
1280 than clear, and added the id "codeigniter_profiler" to the
1281 container div.

2133 __get() or __set() functions were used within models or
2134 controllers.
2135- Fixed a pagination bug that was permitting negative values in the
2136 URL.
2137- Fixed an oversight in which the Loader class was not allowed to be

2149Version 1.4.1
2150=============
2151
2152Release Date: September 21, 2006
2153
2154- Added a new feature that passes URI segments directly to your
2155 function calls as parameters. See the
2156 :doc:`Controllers <general/controllers>` page for more info.
2157- Added support for a function named _output(), which when used in
2158 your controllers will received the final rendered output from the
2159 output class. More info in the :doc:`Controllers <general/controllers>`
2160 page.
2161- Added several new functions in the :doc:`URI
2162 Class <./libraries/uri>` to let you retrieve and manipulate URI
2163 segments that have been re-routed using the :doc:`URI
2164 Routing <general/routing>` feature. Previously, the URI class did not
2165 permit you to access any re-routed URI segments, but now it does.
2166- Added :doc:`$this->output->set_header() <./libraries/output>`
2167 function, which allows you to set server headers.
2168- Updated plugins, helpers, and language classes to allow your
2169 application folder to contain its own plugins, helpers, and language
2170 folders. Previously they were always treated as global for your
2171 entire installation. If your application folder contains any of these
2172 resources they will be used *instead* the global ones.
2173- Added :doc:`Inflector helper <./helpers/inflector_helper>`.
2174- Added element() function in the :doc:`array
2175 helper <./helpers/array_helper>`.
2176- Added RAND() to active record orderby() function.
2177- Added delete_cookie() and get_cookie() to :doc:`Cookie
2178 helper <./helpers/cookie_helper>`, even though the input class
2179 has a cookie fetching function.
2180- Added Oracle database driver (still undergoing testing so it might
2181 have some bugs).
2182- Added the ability to combine pseudo-variables and php variables in
2183 the template parser class.
2184- Added output compression option to the config file.
2185- Removed the is_numeric test from the db->escape() function.
2186- Fixed a MySQLi bug that was causing error messages not to contain
2187 proper error data.
2188- Fixed a bug in the email class which was causing it to ignore
2189 explicitly set alternative headers.
2190- Fixed a bug that was causing a PHP error when the Exceptions class
2191 was called within the get_config() function since it was causing
2192 problems.
2193- Fixed an oversight in the cookie helper in which the config file
2194 cookie settings were not being honored.
2195- Fixed an oversight in the upload class. An item mentioned in the 1.4
2196 changelog was missing.
2197- Added some code to allow email attachments to be reset when sending
2198 batches of email.
2199- Deprecated the application/scripts folder. It will continue to work
2200 for legacy users, but it is recommended that you create your own
2201 :doc:`libraries <./general/libraries>` or
2202 :doc:`models <./general/models>` instead. It was originally added
2203 before CI had user libraries or models, but it's not needed anymore.
2204- Deprecated the $autoload['core'] item from the autoload.php file.
2205 Instead, please now use: $autoload['libraries']
2206- Deprecated the following database functions:
2207 $this->db->smart_escape_str() and $this->db->fields().

2215 into and modify the inner workings of the framework without hacking
2216 the core files.
2217- Added the ability to organize controller files :doc:`into
2218 sub-folders <general/controllers>`. Kudos to Marco for
2219 `suggesting <http://codeigniter.com/forums/viewthread/627/>`_ this
2220 (and the next two) feature.
kenjis087a7a82011-10-20 20:08:47 +09002221- Added regular expressions support for :doc:`routing

2237 file in the applications/config/ folder.
2238- Updated the Upload class to allow the upload field name to be set
2239 when calling :doc:`do_upload() <./libraries/file_uploading>`.
2240- Updated the :doc:`Config Library <./libraries/config>` to be able to
2241 load config files silently, and to be able to assign config files to
2242 their own index (to avoid collisions if you use multiple config
2243 files).
2244- Updated the URI Protocol code to allow more options so that URLs will
2245 work more reliably in different environments.
2246- Updated the form_open() helper to allow the GET method to be used.
2247- Updated the MySQLi execute() function with some code to help prevent
2248 lost connection errors.
2249- Updated the SQLite Driver to check for object support before
2250 attempting to return results as objects. If unsupported it returns an

2262 that it's a private function.
2263- Deprecated the hash() function due to a naming conflict with a native

2273 changing the case of certain words.
2274- Fixed some missing prefixes when using the database prefix feature.
2275- Fixed a typo in the Calendar class (cal_november).

2303
2304- Models do **not** connect automatically to the database as of this
2305 version. :doc:`More info here <./general/models>`.
2306- Updated the Sessions class to utilize the active record class when
2307 running session related queries. Previously the queries assumed MySQL
2308 syntax.
2309- Updated alternator() function to re-initialize when called with no
2310 arguments, allowing multiple calls.
2311- Fixed a bug in the active record "having" function.
2312- Fixed a problem in the validation class which was making checkboxes
2313 be ignored when required.

2330Release Date: April 17, 2006
2331
2332- Changed the behavior of the validation class such that if a
2333 "required" rule is NOT explicitly stated for a field then all other
2334 tests get ignored.
2335- Fixed a bug in the Controller class that was causing it to look in
2336 the local "init" folder instead of the main system one.
2337- Fixed a bug in the init_pagination file. The $config item was not
2338 being set correctly.
2339- Fixed a bug in the auto typography helper that was causing

2349- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
2350- Added the ability to pass objects to the **insert()** and
2351 **update()** database functions. This feature enables you to (among
2352 other things) use your :doc:`Model class <./general/models>`
2353 variables to run queries with. See the Models page for details.
2354- Added the ability to pass objects to the :doc:`view loading
2355 function <./general/views>`: $this->load->view('my_view',
2356 $object);

Derek Jonesce79be02012-06-25 23:23:46 -07002360 class <./database/query_builder>`.
Derek Jones8ede1a22011-10-05 13:34:52 -05002361- Added language file for scaffolding and fixed a scaffolding bug that
2362 occurs when there are no rows in the specified table.

2364 allows you to view your last query that was run.
2365- Added a new mime type to the upload class for better compatibility.
2366- Changed how cache files are read to prevent PHP errors if the cache
2367 file contains an XML tag, which PHP wants to interpret as a short
2368 tag.

2377Version 1.3
2378===========
2379
2380Release Date: April 3, 2006
2381
2382- Added support for :doc:`Models <general/models>`.
2383- Redesigned the database libraries to support additional RDBMs
2384 (Postgres, MySQLi, etc.).
Derek Jonesce79be02012-06-25 23:23:46 -07002385- Redesigned the :doc:`Active Record class <./database/query_builder>`
Derek Jones8ede1a22011-10-05 13:34:52 -05002386 to enable more varied types of queries with simpler syntax, and
2387 advanced features like JOINs.
2388- Added a feature to the database class that lets you run :doc:`custom
2389 function calls <./database/call_function>`.
2390- Added support for :doc:`private functions <general/controllers>` in your
2391 controllers. Any controller function name that starts with an
2392 underscore will not be served by a URI request.
2393- Added the ability to pass your own initialization parameters to your
2394 :doc:`custom core libraries <general/creating_libraries>` when using
2395 $this->load->library()
2396- Added support for running standard :doc:`query string URLs <general/urls>`.
2397 These can be optionally enabled in your config file.
2398- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
2399 appended to your URLs. For example, you could add .html to your URLs,
2400 making them appear static. This feature is enabled in your config
2401 file.
2402- Added a new error template for use with native PHP errors.
2403- Added "alternator" function in the :doc:`string
2404 helpers <./helpers/string_helper>`.
2405- Removed slashing from the input class. After much debate we decided
2406 to kill this feature.
2407- Change the commenting style in the scripts to the PEAR standard so
2408 that IDEs and tools like phpDocumenter can harvest the comments.
2409- Added better class and function name-spacing to avoid collisions with
2410 user developed classes. All CodeIgniter classes are now prefixed with
2411 CI\_ and all controller methods are prefixed with _ci to avoid
2412 controller collisions. A list of reserved function names can be
2413 :doc:`found here <general/controllers>`.
2414- Redesigned how the "CI" super object is referenced, depending on
2415 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2416 way to manage objects that utilizes a bit less resources.
2417- Deprecated: $this->db->use_table() has been deprecated. Please read
Derek Jonesce79be02012-06-25 23:23:46 -07002418 the :doc:`Active Record <./database/query_builder>` page for
Derek Jones8ede1a22011-10-05 13:34:52 -05002419 information.

2422- Fixed a bug in the exception handler which was preventing some PHP
2423 errors from showing up.

2434- Redesigned some internal aspects of the framework to resolve scoping
2435 problems that surfaced during the beta tests. The problem was most
2436 notable when instantiating classes in your constructors, particularly
2437 if those classes in turn did work in their constructors.
2438- Added a global function named
2439 :doc:`get_instance() <general/ancillary_classes>` allowing the main
2440 CodeIgniter object to be accessible throughout your own classes.
2441- Added new :doc:`File Helper <./helpers/file_helper>`:
2442 delete_files()
2443- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2444 index_page()
2445- Added the ability to create your own :doc:`core
2446 libraries <general/creating_libraries>` and store them in your local
2447 application directory.
2448- Added an overwrite option to the :doc:`Upload
2449 class <./libraries/file_uploading>`, enabling files to be
2450 overwritten rather than having the file name appended.
2451- Added Javascript Calendar plugin.
2452- Added search feature to user guide. Note: This is done using Google,
2453 which at the time of this writing has not crawled all the pages of
2454 the docs.
2455- Updated the parser class so that it allows tag pars within other tag
2456 pairs.
2457- Fixed a bug in the DB "where" function.
2458- Fixed a bug that was preventing custom config files to be
