v2.0.1

Quaternionic v2.0.1

Diff since v2.0.0

Fixes an issue with some auto-differentiation packages (e.g., ForwardDiff) where NaNs would be computed for the second derivative of the exponential of 0, rather than regular values. Derivatives with those packages should now be accurate to second order, though they may still fail at higher order for this particular value.

v2.0.0

Quaternionic v2.0.0

This is barely a breaking release. Latexify is no longer required, so some displayed quaternions for some use cases will not look quite as nice any more. However, the functionality is included as an extension, so simply calling using Latexify will re-enable the nicer display formats.

At the same time, the minimum acceptable version of StaticArrays.jl has increased from 1 to 1.8.1 — which, as of this writing, is 10 months old, so hopefully it won't be very disruptive either. This is to support its integration with ChainRulesCore.jl.
