+# v0.3.0
+### Breaking Changes:
+* `KosherZmanim` is no longer an instantiable class, and the classes are no longer exported under `KosherZmanim.lib.*`.
+Instead, everything is exported as named exports. See the Usage section in the [README](./README.md) for more details.
+* Default exports have been converted to named exports.
+* `KosherZmanim.getZmanimXML()` and `ZmanimFormatter.toXML()` have been deprecated.
+* Fixes based on KosherJava updates may have breaking changes. For example, `ZmanimCalculator` was removed. See KosherJava for more details.
