Added

• Improved documentation slightly.

Changed

• Internal optimizations.

Changed

• BREAKING: Changed links key from objc_0_2 to objc_0_3 (so DEP_OBJC_0_2_CC_ARGS in build scripts becomes DEP_OBJC_0_3_CC_ARGS).

• BREAKING: Apple's runtime is now always the default.

Removed

• BREAKING: Removed type aliases Class, Ivar, Method and Protocol since they could be mistaken for the objc2::runtime structs with the same name.

• BREAKING: Removed objc_hook_getClass and objc_hook_lazyClassNamer type aliases (for now).
• BREAKING: Removed DEP_OBJC_RUNTIME build script output.

Initial release.
