### New code organization

Sequel is now divided into two parts: sequel_core and sequel_model. These two parts are distributed as two separate gems. The sequel gem bundles sequel_core and sequel_model together. If you don‘t use Sequel::Model in your code, you can just install and use sequel_core.

### New model hooks implementation

The hooks implementation have been rewritten from scratch, is much more robust and offers a few new features:

- More ways to define hooks: hooks can now be defined by supplying a

block or a method name, or by overriding the hook instance method.

- Inheritable hooks: Hooks can now be inherited, which means that you

can define general hooks in a model superclass, and use them in subclasses. You can also define global hooks on Sequel::Model that will be invoked for all model classes.

- Hook chains can be broken by returning false from within the hook.
- New after_initialize hook, invoked after instance initialization.
- The hook invocation order can no longer be changed. Hooks are

invoked in order of definition, from the top of the class hierarchy (that is, from Sequel::Model) down to the specific class.

### Miscellanea

- Removed deprecated adapter stubs, and all other deprecations in both

sequel_core and sequel_model.

- Fixed String#to_time to raise error correctly for invalid time

stamps.

- Fixed error behavior when parse_tree or ruby2ruby are not available.
