- Adding $escape parameter to the order_by() method, this enables ordering by custom fields.
- Improved support for the MySQLi driver, including:

Version 2.0.3
=============
Release Date: August 20, 2011
- Security
- An improvement was made to the MySQL and MySQLi drivers to prevent
exposing a potential vector for SQL injection on sites using
multi-byte character sets in the database client connection.
An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
*mysql_set_charset()* creates a situation where using multi-byte
character sets on these environments may potentially expose a SQL
injection attack vector. Latin-1, UTF-8, and other "low ASCII"
character sets are unaffected on all environments.
If you are running or considering running a multi-byte character
set for your database connection, please pay close attention to
the server environment you are deploying on to ensure you are not
vulnerable.
- General Changes
- Fixed a bug where there was a misspelling within a code comment in
the index.php file.
- Added Session Class userdata to the output profiler. Additionally,
added a show/hide toggle on HTTP Headers, Session Data and Config
Variables.

- Visual updates to the welcome_message view file and default error
templates. Thanks to `danijelb <https://bitbucket.org/danijelb>`_
for the pull request.
- Added insert_batch() function to the PostgreSQL database driver.
Thanks to epallerols for the patch.

- Added an optional third parameter to heading() which allows adding
html attributes to the rendered heading tag.
- form_open() now only adds a hidden (Cross-site Reference Forgery)
protection field when the form's action is internal and is set to
the post method. (Reactor #165)
- Re-worked plural() and singular() functions in the :doc:`Inflector
helper <helpers/inflector_helper>` to support considerably
more words.
- Libraries
- Altered Session to use a longer match against the user_agent
string. See upgrade notes if using database sessions.
- Added $this->db->set_dbprefix() to the :doc:`Database
Driver <database/queries>`.

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

=============
Release Date: January 28, 2011
Hg Tag: v2.0.0
- General changes
- PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.
- Scaffolding, having been deprecated for a number of versions, has
been removed.
- Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
has been converted to a Helper and

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

fails XSS checks.
- Added stripslashes() and trim()ing of double quotes from $_FILES
type value to standardize input in Upload library.
- Added a second parameter (boolean) to
$this->zip->read_dir('/path/to/directory', FALSE) to remove the
preceding trail of empty folders when creating a Zip archive. This
example would contain a zip with "directory" and all of its
contents.

Version 1.7
===========
Release Date: October 23, 2008
Hg Tag: 1.7.0
- Libraries
- Added a new :doc:`Form Validation
Class <libraries/form_validation>`. It simplifies setting
rules and field names, supports arrays as field names, allows
groups of validation rules to be saved in a config file, and adds
some helper functions for use in view files. **Please note that
the old Validation class is now deprecated**. We will leave it in
the library folder for some time so that existing applications
that use it will not break, but you are encouraged to migrate to
the new version.
- Updated the :doc:`Sessions class <libraries/sessions>` so that
any custom data being saved gets stored to a database rather than
the session cookie (assuming you are using a database to store
session data), permitting much more data to be saved.

either the main "libraries" or the local application "libraries"
folder. Please see the :doc:`Loader class <libraries/loader>` for
more info.
- Added the ability to assign library objects to your own variable
names when you use $this->load->library(). Please see the :doc:`Loader
class <libraries/loader>` for more info.

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

helper into its own :doc:`Typography
Class <libraries/typography>`.
- Improved performance and accuracy of xss_clean(), including
reduction of false positives on image/file tests.

multiple calls to the parse() function. The output of each is
appended in the output.
- Added max_filename option to set a file name length limit in the
:doc:`File Upload Class <libraries/file_uploading>`.
- Added set_status_header() function to :doc:`Output
