+## v1.1.0
+
+### Better parsing
+Updated [error-stack-parser](https://github.com/stacktracejs/error-stack-parser) to v1.3 which parses eval stack entries in a better way and fixes a bunch of bugs. 
+
+### Better resource handling
+Updated [stacktrace-gps](https://github.com/stacktracejs/stacktrace-gps). Now reuses the same instance to avoid duplicate requests for the same resource by default. 
+
+### Better dev experience
+JSCS and automated PR testing have been implemented to ensure consistent styles and quick feedback.
+
+> Possibly breaking changes: ErrorStackParser now provides it's own polyfill for `Array.map` and `Array.filter`. `eval` information is will display differently in stack traces.
+
 ## v1.0.0
 
 ### stacktrace.js is reborn
