CHANGELOG.md

1.0.3

• More performance improvements (details below).
• Calling memoize(:value) { ... } now defines a __value___ method as well as a value method.

Performance improvements

1. The instance version of memoize now only checks with the variable is defined if instance_variable_get returns a false value. This yields a modest improvement in performance.
2. The class version of memoize no longer piggy-backs on the instance version. Instead it defines a __value__ method using the provided block, then defines a value method using class_eval. This yields a dramatic improvement in performance, making the class version almost as fast as doing it yourself.

1.0.2

Performance improvement.

1.0.1

Stopped using ActiveSupport::Concern even when available.

1.0.0

Initial release.
