Version 1.8.0

on GitHub

Major new feature set: comprehensive support for events, watching, callbacks, and dependencies

• Parameterized methods can now declare @depends(p,q) to indicate that they depend on parameters p and q (defaulting to all parameters)
• Parameterized methods can depend on subobjects with @depends(p.param,q.param.r), where p.param indicates dependencies on all parameters of p and q.param.r indicates a dependency on parameter r of q.
• Functions and methods can watch parameter values, re-running when those values change or when an explicit trigger is issued, and can unwatch them later if needed.
• Multiple events can be batched to trigger callbacks only once for a coordinated set of changes

Other new features:

• Added support in ObjectSelector for selecting lists and dicts (#268)
• Added pandas DataFrame and Series parameter types (#285)
• Added support for regular expression validation to String Parameter (#241, #245)
