这个版本比较v1.3有了比较多的更改，v1.4发布后将会增加新的功能到v1.5中去，下面主要列出了本次版本的更改纪录：

Important fixes or changes

• fixed DB class error about missing PDO::MYSQL_ATTR_COMPRESS constant
• you are now REQUIRED to set a correct php timezone. The FuelPHP default value of 'UTC' has been removed, as it would cause date conversion errors that are difficult to find. Most notable, you will have issues with session and cookie expiration.
• ALL default configuration has been moved to core/config. Only use the app/config folder for application specific overrides of default values, or for custom configuration.

Backward compability notes

This release features a new Pagination class that isn't completely backward compatible with the API from previous versions. We have put a lot of effort in emulating the old behaviour of the class, but as PHP doesn't support magic getters/setters for static properties, you'll have to replace those in your code manually when you upgrade to v1.4. The required changes can be found in thedocumentation.

Removed code (because it was deprecated in v1.3)

• Removed "auto_encode_view_data" config key, deprecated in v1.2
• Fuel: Removed Fuel::add_module(), deprecated in v1.2. Use Module::load() instead.
• Fuel: Removed Fuel::module_exists(), deprecated in v1.2. Use Module::exists() instead.
• Theme: Removed $theme->asset(), deprecated in v1.2. Use $theme->asset_path() instead.
• Theme: Removed $theme->info(), deprecated in v1.2. Use $theme->get_info() instead.
• Theme: Removed $theme->all_info(), deprecated in v1.2. Use $theme->load_info() instead.
• Orm\Model : Removed $model->values(), deprecated in v1.3. Use $model->set() instead.

Code deprecated in v1.4 (to be removed in the next release)

• Redis: Redis::instance() will no longer create new objects. Use Redis::forge() for that.
• Orm\Model: Using the find() method without parameters is deprecated. Use query() instead.
