详细更改记录：
- General changes
- PHP 4 support is deprecated. Features new to 2.0.0 may not support PHP 4, and all legacy features will no longer support PHP 4 as of 2.1.0.
- 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 documented. The JavaScript calendar plugin was removed due to the ready availability of great JavaScript calendars, particularly with jQuery.
- Added new special Library type: Drivers.
- Moved the application folder outside of the system folder.
- Added routing overrides to the main index.php file, enabling the normal routing to be overridden on a per "index" file basis.
- Added the ability to set config values (or override config values) directly from data set in the main index.php file. This allows a single application to be used with multiple front controllers, each having its own config values.
- Added $config['directory_trigger'] to the config file so that a 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 Loader class documentation for more details.
- In-development code is now hosted at BitBucket.
- Removed the deprecated Validation Class.
- Libraries
- Added Security library, which now contains the xss_clean function, filename_security function and other security related functions.
添加安全类，包含xss_clean，filename_security在内的一些安全验证方法； - Added CSRF (Cross-site Reference Forgery) protection to the Security library.
添加跨站攻击防范 - Added $parse_exec_vars property to Output library.
输出类添加了一个属性，用于关闭解析{elapsed_time} 和 {memory_usage}这两个标签。 - Added ability to enable / disable individual sections of the Profiler
可以单独使用评测器中的某一项或多个。 - Added a wildcard option $config['allowed_types'] = '*' to the File Uploading Class.
修改上传类，允许所有文件上传 - Added an 'object' config variable to the XML-RPC Server library so that one can specify the object to look for requested methods, instead of assuming it is in the $CI superobject.
加强XML-RPC Server类 - Added "is_object" into the list of unit tests capable of being run.
- Table library will generate an empty cell with a blank string, or NULL value.
表格类，现在可以在空单元格显示空字符或者是Null - Added ability to set tag attributes for individual cells in the Table library
表格类可以指定某单元格一个Class属性 - Added a parse_string() method to the Parser Class.
解析类添加一个方法parse_string() 。（手册上好像没有） - Added HTTP headers and Config information to the Profiler output.
评测器可以显示Http报头和配置信息（config数组变量）。 - Added Chrome and Flock to the list of detectable browsers by browser() in the User Agent Class.
User-Agent 类中添加Chrome and Flock支持 - The Unit Test Class now has an optional "notes" field available to it, and allows for discrete display of test result items using $this->unit->set_test_items().
单元测试类添加了一些细节。 - Added a $xss_clean class variable to the XMLRPC library, enabling control over the use of the Security library's xss_clean() method.
- Added a download() method to the FTP library
FTP类添加download() 方法 - Changed do_xss_clean() to return FALSE if the uploaded file fails XSS checks.
修改do_xss_clean()返回值 - Added stripslashes() and trim()ing of double quotes from $_FILES type value to standardize input in Upload library.
上传类添加了两个方法stripslashes() and trim()使上传类得到标准化的的文件路径信息。
- Database
- Added swap_pre value to database configuration.
- Added autoinit value to database configuration.
- Added stricton value to database configuration.
- Added database_exists() to the Database Utilities Class.
- Semantic change to db->version() function to allow a list of exceptions for databases with functions to return version string instead of specially formed SQL queries. Currently this list only includes Oracle and SQLite.
- Fixed a bug where driver specific table identifier protection could lead to malformed queries in the field_data() functions.
- Fixed a bug where an undefined class variable was referenced in database drivers.
- Helpers
- Added convert_accented_characters() function to text helper.
- Added accept-charset to the list of inserted attributes of form_open() in the Form Helper.
- Deprecated the dohash() function in favour of do_hash() for naming consistency.
- Non-backwards compatible change made to get_dir_file_info() in the File Helper. No longer recurses by default so as to encourage responsible use (this function can cause server performance issues when used without caution).
- Modified the second parameter of directory_map() in the Directory Helper to accept an integer to specify recursion depth.
- Modified delete_files() in the File Helper to return FALSE on failure.
- Added an optional second parameter to byte_format() in the Number Helper to allow for decimal precision.
- Added alpha, and sha1 string types to random_string() in the String Helper.
- Modified prep_url() so as to not prepend http:// if the supplied string already has a scheme.
- Modified get_file_info in the file helper, changing filectime() to filemtime() for dates.
- Modified smiley_js() to add optional third parameter to return only the javascript with no script tags.
- Other Changes
- Updated loader to automatically apply the sub-class prefix as an option when loading classes. Class names can be prefixed with the standard "CI_" or the same prefix as the subclass prefix, or no prefix at all.
- Increased randomness with is_really_writable() to avoid file collisions when hundreds or thousands of requests occur at once.
- Switched some DIR_WRITE_MODE constant uses to FILE_WRITE_MODE where files and not directories are being operated on.
- get_mime_by_extension() is now case insensitive.
- Added "default" to the list Reserved Names.
- Added 'application/x-msdownload' for .exe files and ''application/x-gzip-compressed' for .tgz files to config/mimes.php.
- Updated the output library to no longer compress output or send content-length headers if the server runs with zlib.output_compression enabled.
- Eliminated a call to is_really_writable() on each request unless it is really needed (Output caching)
- Documented append_output() in the Output Class.
- Documented a second argument in the decode() function for the Encryption Class.
- Documented db->close().
- Moved _remove_invisible_characters() function from the Security Library to common functions.
