+### Jan 12th, 2023
+* Added support for resolving value definitions from references to other defined variables with the following syntax,`${spock.var:SpockClass.defined_variable}`
+* Added support for new fundamental types: (1) file: this is an overload of a str that verifies file existence and (r/w) access (2) directory: this is an overload of a str that verifies directory existence, creation if not existing, and (r/w) access
+* Deprecated support for `List` of repeated `@spock` decorated classes.

-* Added `evolve` support to the underlying `SpockBuilder` class. This provides functionality similar to the underlying
-attrs library ([attrs.evolve](https://www.attrs.org/en/stable/api.html#attrs.evolve)). `evolve()` creates a new

-#### January 18th, 2022
-* Support for lazy evaluation: (1) inherited classes do not need to be `@spock` decorated, (2) dependencies/references 
-between `spock` classes can be lazily handled thus preventing the need for every `@spock` decorated classes to be 
-passed into `*args` within the main `SpockBuilder` API
-* Updated main API interface for better top-level imports (backwards compatible): `ConfigArgBuilder`->`SpockBuilder`
-* Added stubs to the underlying decorator that should help with type hinting in VSCode (pylance/pyright)
