1399=============
1400
1401Release Date: August 20, 2011
1402
1403- Security
1404
1405 - An improvement was made to the MySQL and MySQLi drivers to prevent
1406 exposing a potential vector for SQL injection on sites using
1407 multi-byte character sets in the database client connection.
1408 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
1409 *mysql_set_charset()* creates a situation where using multi-byte
1410 character sets on these environments may potentially expose a SQL
1411 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
1412 character sets are unaffected on all environments.
1413
1414 If you are running or considering running a multi-byte character
1415 set for your database connection, please pay close attention to
1416 the server environment you are deploying on to ensure you are not
1417 vulnerable.
1418

1466- Changed server check to ensure SCRIPT_NAME is defined. (Reactor #57)
1467- Removed APPPATH.'third_party' from the packages autoloader to negate
1468 needless file stats if no packages exist or if the developer does not
1469 load any other packages by default.
1470- Fixed a bug (Reactor #231) where Sessions Library database table
1471 example SQL did not contain an index on last_activity. See :doc:`Upgrade
1472 Notes <installation/upgrade_203>`.
1473- Fixed a bug (Reactor #229) where the Sessions Library example SQL in
1474 the documentation contained incorrect SQL.
1475- Fixed a bug (Core #340) where when passing in the second parameter to
1476 $this->db->select(), column names in subsequent queries would not be
1477 properly escaped.
1478- Fixed issue #199 - Attributes passed as string does not include a
1479 space between it and the opening tag.
1480- Fixed a bug where the method $this->cart->total_items() from :doc:`Cart
1481 Library <libraries/cart>` now returns the sum of the quantity
1482 of all items in the cart instead of your total count.
1483- Fixed a bug where not setting 'null' when adding fields in db_forge
1484 for mysql and mysqli drivers would default to NULL instead of NOT
1485 NULL as the docs suggest.
1486- Fixed a bug where using $this->db->select_max(),
1487 $this->db->select_min(), etc could throw notices. Thanks to w43l for
1488 the patch.
1489- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
1490 whole is more reliable. This should get parameters in crontab
1491 working.

1598=============
1599
1600Release Date: January 28, 2011
1601Hg Tag: v2.0.0
1602
1603- General changes
1604
1605 - PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.
1606 - Scaffolding, having been deprecated for a number of versions, has
1607 been removed.
1608 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
1609 has been converted to a Helper and
1610 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
1611 calendar plugin was removed due to the ready availability of great
1612 JavaScript calendars, particularly with jQuery.
1613 - Added new special Library type:
1614 :doc:`Drivers <./general/drivers>`.
1615 - Added full query-string support. See the config file for details.
1616 - Moved the application folder outside of the system folder.
1617 - Moved system/cache and system/logs directories to the application
1618 directory.
1619 - Added routing overrides to the main index.php file, enabling the
1620 normal routing to be overridden on a per "index" file basis.
1621 - Added the ability to set config values (or override config values)
1622 directly from data set in the main index.php file. This allows a
1623 single application to be used with multiple front controllers,
1624 each having its own config values.
1625 - Added $config['directory_trigger'] to the config file so that a
1626 controller sub-directory can be specified when running _GET
1627 strings instead of URI segments.
1628 - Added ability to set "Package" paths - specific paths where the
1629 Loader and Config classes should try to look first for a requested
1630 file. This allows distribution of sub-applications with their own
1631 libraries, models, config files, etc. in a single "package"
1632 directory. See the :doc:`Loader class <libraries/loader>`
1633 documentation for more details.

Derek Jones8ede1a22011-10-05 13:34:52 -05001639 now be set without an extension, the extension will be taken from
1640 the uploaded file instead of the given name.
1641 - In :doc:`Database Forge <database/forge>` the name can be omitted
1642 from $this->dbforge->modify_column()'s 2nd param if you aren't
1643 changing the name.
1644 - $config['base_url'] is now empty by default and will guess what
1645 it should be.
1646 - Enabled full Command Line Interface compatibility with
1647 config['uri_protocol'] = 'CLI';.
1648

1652 memcached, and file-based support.
1653 - Added $prefix, $suffix and $first_url properties to :doc:`Pagination
1654 library <./libraries/pagination>`.

1667 :doc:`File Uploading Class <./libraries/file_uploading>`.
1668 - Added an 'object' config variable to the XML-RPC Server library so
1669 that one can specify the object to look for requested methods,
1670 instead of assuming it is in the $CI superobject.
1671 - Added "is_object" into the list of unit tests capable of being
1672 run.
1673 - Table library will generate an empty cell with a blank string, or
1674 NULL value.
1675 - Added ability to set tag attributes for individual cells in the

1685 display of test result items using
1686 $this->unit->set_test_items().
1687 - Added a $xss_clean class variable to the XMLRPC library, enabling
1688 control over the use of the Security library's xss_clean()

1695 type value to standardize input in Upload library.
1696 - Added a second parameter (boolean) to
1697 $this->zip->read_dir('/path/to/directory', FALSE) to remove the
1698 preceding trail of empty folders when creating a Zip archive. This
1699 example would contain a zip with "directory" and all of its
1700 contents.
1701 - Added ability in the Image Library to handle PNG transparency for
1702 resize operations when using the GD lib.
1703 - Modified the Session class to prevent use if no encryption key is

1726 get() will return all POST and GET items (respectively) if there
1727 are no parameters passed in.

1736 - Added database_exists() to the :doc:`Database Utilities
1737 Class <database/utilities>`.
1738 - Semantic change to db->version() function to allow a list of

1762 - Non-backwards compatible change made to get_dir_file_info() in
1763 the :doc:`File Helper <helpers/file_helper>`. No longer recurses

2124
2125- Libraries
2126
2127 - Added a new :doc:`Form Validation
2128 Class <libraries/form_validation>`. It simplifies setting
2129 rules and field names, supports arrays as field names, allows
2130 groups of validation rules to be saved in a config file, and adds
2131 some helper functions for use in view files. **Please note that
2132 the old Validation class is now deprecated**. We will leave it in
2133 the library folder for some time so that existing applications
2134 that use it will not break, but you are encouraged to migrate to
2135 the new version.
2136 - Updated the :doc:`Sessions class <libraries/sessions>` so that
2137 any custom data being saved gets stored to a database rather than
2138 the session cookie (assuming you are using a database to store
2139 session data), permitting much more data to be saved.
2140 - Added the ability to store libraries in subdirectories within
2141 either the main "libraries" or the local application "libraries"
2142 folder. Please see the :doc:`Loader class <libraries/loader>` for
2143 more info.
2144 - Added the ability to assign library objects to your own variable
2145 names when you use $this->load->library(). Please see the :doc:`Loader
2146 class <libraries/loader>` for more info.
2147 - Added controller class/method info to :doc:`Profiler
2148 class <general/profiling>` and support for multiple database
2149 connections.

2151 helper into its own :doc:`Typography
2152 Class <libraries/typography>`.
2153 - Improved performance and accuracy of xss_clean(), including
2154 reduction of false positives on image/file tests.
2155 - Improved :doc:`Parser class <./libraries/parser>` to allow
2156 multiple calls to the parse() function. The output of each is
2157 appended in the output.

2159 :doc:`File Upload Class <libraries/file_uploading>`.
2160 - Added set_status_header() function to :doc:`Output
2161 class <libraries/output>`.
2162 - Modified :doc:`Pagination <libraries/pagination>` class to only
2163 output the "First" link when the link for page one would not be
2164 shown.
2165 - Added support for mb_strlen in the :doc:`Form
2166 Validation <libraries/form_validation>` class so that
2167 multi-byte languages will calculate string lengths properly.
2168
2169- Database
2170
2171 - Improved Active Record class to allow full path column and table
2172 names: hostname.database.table.column. Also improved the alias
2173 handling.
2174 - Improved how table and column names are escaped and prefixed. It
2175 now honors full path names when adding prefixes and escaping.
2176 - Added Active Record caching feature to "update" and "delete"
2177 functions.
2178 - Added removal of non-printing control characters in escape_str()
2179 of DB drivers that do not have native PHP escaping mechanisms
2180 (mssql, oci8, odbc), to avoid potential SQL errors, and possible
2181 sources of SQL injection.
2182 - Added port support to MySQL, MySQLi, and MS SQL database drivers.
2183 - Added driver name variable in each DB driver, based on bug report
2184 #4436.
2185
2186- Helpers
2187
2188 - Added several new "setting" functions to the :doc:`Form
2189 helper <helpers/form_helper>` that allow POST data to be
2190 retrieved and set into forms. These are intended to be used on
2191 their own, or with the new :doc:`Form Validation
2192 Class <libraries/form_validation>`.
2193 - Added current_url() and uri_segments() to :doc:`URL
2194 helper <helpers/url_helper>`.
2195 - Altered auto_link() in the :doc:`URL
2196 helper <helpers/url_helper>` so that email addresses with
2197 "+" included will be linked.
2198 - Added meta() function to :doc:`HTML
2199 helper <helpers/html_helper>`.
2200 - Improved accuracy of calculations in :doc:`Number
2201 helper <helpers/number_helper>`.
2202 - Removed added newlines ("\\n") from most form and html helper
2203 functions.
2204 - Tightened up validation in the :doc:`Date
2205 helper <helpers/date_helper>` function human_to_unix(),
2206 and eliminated the POSIX regex.
2207 - Updated :doc:`Date helper <helpers/date_helper>` to match the
2208 world's current time zones and offsets.
2209 - Modified url_title() in the :doc:`URL
2210 helper <helpers/url_helper>` to remove characters and digits
2211 that are part of character entities, to allow dashes, underscores,
2212 and periods regardless of the $separator, and to allow uppercase
2213 characters.
2214 - Added support for arbitrary attributes in anchor_popup() of the
2215 :doc:`URL helper <helpers/url_helper>`.
2216
2217- Other Changes
2218
2219 - Added :doc:`PHP Style Guide <./general/styleguide>` to docs.
2220 - Added sanitization in xss_clean() for a deprecated HTML tag that
2221 could be abused in user input in Internet Explorer.
2222 - Added a few openxml document mime types, and an additional mobile
2223 agent to mimes.php and user_agents.php respectively.
2224 - Added a file lock check during caching, before trying to write to
2225 the file.
2226 - Modified Cookie key cleaning to unset a few troublesome key names
2227 that can be present in certain environments, preventing CI from
2228 halting execution.
2229 - Changed the output of the profiler to use style attribute rather
2230 than clear, and added the id "codeigniter_profiler" to the
2231 container div.

3141 problems.
3142- Fixed an oversight in the cookie helper in which the config file
3143 cookie settings were not being honored.

3149 for legacy users, but it is recommended that you create your own
3150 :doc:`libraries <./general/libraries>` or

3154 Instead, please now use: $autoload['libraries']

3188- Updated the :doc:`Config Library <./libraries/config>` to be able to
3189 load config files silently, and to be able to assign config files to

3247Version 1.3.3
3248=============
3249
3250Release Date: June 1, 2006
3251
3252- Models do **not** connect automatically to the database as of this
3253 version. :doc:`More info here <./general/models>`.
3254- Updated the Sessions class to utilize the active record class when
3255 running session related queries. Previously the queries assumed MySQL
3256 syntax.
3257- Updated alternator() function to re-initialize when called with no
3258 arguments, allowing multiple calls.
3259- Fixed a bug in the active record "having" function.
3260- Fixed a problem in the validation class which was making checkboxes
3261 be ignored when required.
3262- Fixed a bug in the word_limiter() helper function. It was cutting
3263 off the fist word.
3264- Fixed a bug in the xss_clean function due to a PHP bug that affects
3265 some versions of html_entity_decode.
3266- Fixed a validation bug that was preventing rules from being set twice
3267 in one controller.

3276=============
3277
3278Release Date: April 17, 2006
3279
3280- Changed the behavior of the validation class such that if a
3281 "required" rule is NOT explicitly stated for a field then all other
3282 tests get ignored.
3283- Fixed a bug in the Controller class that was causing it to look in
3284 the local "init" folder instead of the main system one.
3285- Fixed a bug in the init_pagination file. The $config item was not
3286 being set correctly.
3287- Fixed a bug in the auto typography helper that was causing
3288 inconsistent behavior.
3289- Fixed a couple bugs in the Model class.
3290- Fixed some documentation typos and errata.
3291
3292Version 1.3.1
3293=============
3294
3295Release Date: April 11, 2006
3296
3297- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
3298- Added the ability to pass objects to the **insert()** and
3299 **update()** database functions. This feature enables you to (among
3300 other things) use your :doc:`Model class <./general/models>`
3301 variables to run queries with. See the Models page for details.
3302- Added the ability to pass objects to the :doc:`view loading
3303 function <./general/views>`: $this->load->view('my_view',
3304 $object);
3305- Added getwhere function to :doc:`Active Record
Derek Jonesce79be02012-06-25 23:23:46 -07003306 class <./database/query_builder>`.
Derek Jones8ede1a22011-10-05 13:34:52 -05003307- Added count_all function to :doc:`Active Record
Derek Jonesce79be02012-06-25 23:23:46 -07003308 class <./database/query_builder>`.
Derek Jones8ede1a22011-10-05 13:34:52 -05003309- Added language file for scaffolding and fixed a scaffolding bug that
3310 occurs when there are no rows in the specified table.
3311- Added :doc:`$this->db->last_query() <./database/queries>`, which
3312 allows you to view your last query that was run.
3313- Added a new mime type to the upload class for better compatibility.
3314- Changed how cache files are read to prevent PHP errors if the cache
3315 file contains an XML tag, which PHP wants to interpret as a short
3316 tag.
3317- Fixed a bug in a couple of the active record functions (where and
3318 orderby).
3319- Fixed a bug in the image library when realpath() returns false.
3320- Fixed a bug in the Models that was preventing libraries from being
3321 used within them.

3324
3325Version 1.3
3326===========
3327
3328Release Date: April 3, 2006
3329
3330- Added support for :doc:`Models <general/models>`.
3331- Redesigned the database libraries to support additional RDBMs
3332 (Postgres, MySQLi, etc.).
Derek Jonesce79be02012-06-25 23:23:46 -07003333- Redesigned the :doc:`Active Record class <./database/query_builder>`
Derek Jones8ede1a22011-10-05 13:34:52 -05003334 to enable more varied types of queries with simpler syntax, and
3335 advanced features like JOINs.
3336- Added a feature to the database class that lets you run :doc:`custom
3337 function calls <./database/call_function>`.
3338- Added support for :doc:`private functions <general/controllers>` in your
3339 controllers. Any controller function name that starts with an
3340 underscore will not be served by a URI request.
3341- Added the ability to pass your own initialization parameters to your
3342 :doc:`custom core libraries <general/creating_libraries>` when using
3343 $this->load->library()
3344- Added support for running standard :doc:`query string URLs <general/urls>`.
3345 These can be optionally enabled in your config file.
3346- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
3347 appended to your URLs. For example, you could add .html to your URLs,
3348 making them appear static. This feature is enabled in your config
3349 file.
3350- Added a new error template for use with native PHP errors.
3351- Added "alternator" function in the :doc:`string
3352 helpers <./helpers/string_helper>`.
3353- Removed slashing from the input class. After much debate we decided
3354 to kill this feature.
3355- Change the commenting style in the scripts to the PEAR standard so
3356 that IDEs and tools like phpDocumenter can harvest the comments.
3357- Added better class and function name-spacing to avoid collisions with
3358 user developed classes. All CodeIgniter classes are now prefixed with
3359 CI\_ and all controller methods are prefixed with _ci to avoid
3360 controller collisions. A list of reserved function names can be
3361 :doc:`found here <general/controllers>`.
3362- Redesigned how the "CI" super object is referenced, depending on
3363 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
3364 way to manage objects that utilizes a bit less resources.
3365- Deprecated: $this->db->use_table() has been deprecated. Please read
Derek Jonesce79be02012-06-25 23:23:46 -07003366 the :doc:`Active Record <./database/query_builder>` page for
Derek Jones8ede1a22011-10-05 13:34:52 -05003367 information.
3368- Deprecated: $this->db->smart_escape_str() has been deprecated.
3369 Please use this instead: $this->db->escape()
3370- Fixed a bug in the exception handler which was preventing some PHP
3371 errors from showing up.
3372- Fixed a typo in the URI class. $this->total_segment() should be
3373 plural: $this->total_segments()
3374- Fixed some typos in the default calendar template
3375- Fixed some typos in the user guide
3376
3377Version 1.2
3378===========
3379
3380Release Date: March 21, 2006
3381
3382- Redesigned some internal aspects of the framework to resolve scoping
3383 problems that surfaced during the beta tests. The problem was most
3384 notable when instantiating classes in your constructors, particularly
3385 if those classes in turn did work in their constructors.
3386- Added a global function named
3387 :doc:`get_instance() <general/ancillary_classes>` allowing the main
3388 CodeIgniter object to be accessible throughout your own classes.
3389- Added new :doc:`File Helper <./helpers/file_helper>`:
3390 delete_files()
3391- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
3392 index_page()
3393- Added the ability to create your own :doc:`core
3394 libraries <general/creating_libraries>` and store them in your local
3395 application directory.
3396- Added an overwrite option to the :doc:`Upload
3397 class <./libraries/file_uploading>`, enabling files to be
3398 overwritten rather than having the file name appended.
3399- Added Javascript Calendar plugin.
3400- Added search feature to user guide. Note: This is done using Google,
3401 which at the time of this writing has not crawled all the pages of
3402 the docs.
3403- Updated the parser class so that it allows tag pars within other tag
3404 pairs.
3405- Fixed a bug in the DB "where" function.
3406- Fixed a bug that was preventing custom config files to be
3407 auto-loaded.
3408- Fixed a bug in the mysql class bind feature that prevented question
3409 marks in the replacement data.
3410- Fixed some bugs in the xss_clean function

3430 E_STRICT constant
3431- Fixed a data type error in the form_radio function (form helper)
3432- Fixed a bug that was preventing the xss_clean function from being
3433 called from the validation class.

3435 specified as $conf rather than $config
3436- Fixed a pagination problem in the scaffolding.
3437- Fixed a bug in the mysql class "where" function.
3438- Fixed a regex problem in some code that trimmed duplicate slashes.
3439- Fixed a bug in the br() function in the HTML helper
3440- Fixed a syntax mistake in the form_dropdown function in the Form
3441 Helper.
