middleclass changelog

Version 4.0.0

• Unified the method and metamethod lookup into a single algorithm
• Added the capacity of setting up the __index metamethod in classes
• Removed global Object (classes created with class(<name>) have no superclass now)
• Removed default method Class:implements(<mixin>)
• Renamed several internal functions

Version 3.2.0

• Changed the way metamethods were handled to fix certain bugs (un-stubbed metamethods could not be inherited)

Version 3.1.0

• Added Lua 5.3 metamethod support (__band, __bor, __bxor, __shl, __bnot)

Version 3.0.1

• Added __len, __ipairs and __pairs metamethods for Lua 5.2

Version 3.0

• Anything that behaves reasonably like a class can be a class (no internal list of classes)
• The class global function is now just the return value of require 'middleclass'. It is a callable table, but works exactly as before.

• The global function instanceOf becomes class.Object.isInstanceOf. Parameter order is reversed.
• The global function subclassOf becomes class.Object.static.isSubclassOf. Parameter order is reversed.
• The global function implements becomes class.Object.static.implements. Parameter order is reversed.
• Specs have been translated from telescope to busted

Version 2.0

• Static methods are now separated from instance methods
• class.superclass has now become class.super
• It's now possible to do class.subclasses
