 ## [Unreleased]
 
+## [0.2.0] - 2018-03-28
+### Added
+- `Surveyor` class to allow for regex-based URL matching (for manually setting 'current' URL).
+- `Climber::setCurrentUrl()` method to manually set active URL after instantiation. 
+- `Climber::isActivated()` method to determine if any leaf is set active.
+- Better testing for everything.
+- Convenience functions (see README.md).
+- "API"s for all classes in the form of interfaces. Hopefully this will improve backward-compatibility.
+- `Tree::subtree()` method to create subtrees (sub-sections of existing trees).
+- `Forester` class (extends `Spotter`) to feed Trees back into themselves (currently used when creating subtrees).
+
+### Changed
+- Refactored system for setting active URL on Tree so that it is more accessible.
