 ## [Unreleased]
 
+## [0.0.4] - 2018-10-29
+### Changed
+- Moved logging methods into a new `Log` object plus fixed broken `fn()` method (née `currentFn()`) 
+  which identifies the currently executing function name.
+- Logging helper methods `debug()`, `warn()`, and `error()` methods now call respective
+  `console` methods in browsers that support them.
+- Additional fix for issue where `init()` callback could potentially execute before all
+  prerequisite CSS & JS files had completely loaded (esp. when including JS as browser
+  globals) by resolving all promises prior to calling `_inject()`.
+- Fixed minor JS syntax warnings identified by JSHint.
+
+### Added
+- Internal `Log` class containing previous logging methods (as mentioned above), plus new
+  `startTimer()` and `stopTimer()` methods for performance timing when `log_level` is set
+  to `debug`.
+- Added `package.json` and `Gruntfile.js` files for automating syntax validation with JSHint.
