+# v0.7.0 - 25.01.2022
+
+This is a *breaking* release, due to the changes in PR #25.
+
+`NumContext` (and types taking `NumContext` as an argument) are now
+two-fold generic. The floating point like type used during
+computation may now be overwritten.
+
+This is a breaking change, as the `newNumContext` procedure must now
+be given two generic arguments. For most procedures the signature
+was only extended to use `float` as the secondary type, leaving them
+as taking single generic arguments.
+`adapdiveGauss` is an exception and thus now requires the user to
+hand *both* types.
+
+- transition for `adaptiveGauss`:
+  Calling as: `adaptiveGauss[T, float](...)` will produce the old
+  behavior. In the future a nicer interface may be designed.
+- transition for `newNumContext`:
+  Calling as: `newNumContext[T, float]` will produce the old behavior.
+
+This change was a step towards a more (likely concept based) interface
+for SciNim libraries for better interop. It allows for example to
+integrate over a `Measurement`.
