Version 1.8.0

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)

Version 1.7.0

Since the previous release (1.6.1), there should be no changes that affect existing code, only additions:

A new param namespace object, which in future will allow subclasses of Parameterized to have much cleaner namespaces (#230).
Started testing on python 3.7-dev (#223).
param.version now provides functions to simplify dependants' setup.py/setup.cfg files (see holoviz-dev/autover#49).

Although param should still work on python 3.3, we are no longer testing against it (unsupported by our test environment; #234).

Changes

Dropped support for python 2.6 (#175).
No longer attempt to cythonize param during installation via pip (#166, #194).

Allow get_param_values() to work on class (#162).
Fixed incorrect default value for param.Integer (#151).
Allow a String to be None if its default is None (#104).
Fixed ListSelector.compute_default() (#212).
Fixed checks for None in various Parameter subclasses (#208); fixes problems for subclasses of Parameterized that define a custom __nonzero__ or __len__.
