2.0.0 - New API (BC)

2.0.0

This release is a significant overhaul of the existing API, and therefore introduces breaking changes.
See the list of updates below, and consult the README for examples and details of the new API.

• Add Enum::instanceFromKey($key)
• Breaking Change $instance->identifier to $instance->name()
• Breaking Change Enum::identifiers() to Enum::names()
• Breaking Change Enum::getKeyForIdentfier() to Enum::keyForName()
• Breaking Change Enum::valueFor() to Enum::valueForKey()
• Add Enum::nameForKey() to get the constant name for a given key
• Breaking Change Enum::exists() to Enum::isValidKey()
• Breaking Change Enum::checkExists() to Enum::requireValidKey()
• Fix $instance->key() to handle non-string keys
• Fix $instance->is() to handle non-string keys
• Fix late-static binding in some methods which referred to self::
• Add Enum::instanceFromName($name) to get an instance via name (alternative to Enum::NAME())
• Change implementation of Enum::instanceFromKey($key) to use array_search
• Breaking Change: the default provided static map() method will return an array of constant keys mapped to null.
  Previously it returned an empty array [] when not overridden. In practice, this may not effect userland code.
• Breaking Change: you can no longer provide a non-keyed array in an map() method implemented
  in your sub-class. This method should be used to map keys to values (if necessary). A default map() method is provided
  which maps keys to null values.
• Breaking Change Enum::fromValue($val) has been renamed to Enum::keyForValue()
• Breaking Change: removed Enum::flip()
• Breaking Change Enum::constantMap() to Enum::namesAndKeys()
• Updated README to reflect API changes
• Add Enum::valueForName($name) for completeness
