+## Changelog
+
+### 2.0.0
+
+- Library became ES and Common.js compatible.
+- Source code is reorganized to match [original Python library](https://pypi.python.org/pypi/sgp4/).
+- `degreesLat` and `degreesLong` don't adjust input radians value and throw `RangeError` if it's out of bounds
+(breaking change).
+- `invjday` function is added.
+- [Julian day calculations take account of milliseconds](https://github.com/shashwatak/satellite-js/issues/31)
+([#38](https://github.com/shashwatak/satellite-js/pull/38)).
+- [Incorrect position and velocity bug](https://github.com/shashwatak/satellite-js/issues/26) for times not close to
+TLE epoch is fixed ([#37](https://github.com/shashwatak/satellite-js/pull/37)).
+- Continuous integration and test coverage are provided.
+- [Bower support is dropped](https://github.com/shashwatak/satellite-js/issues/40).
