Quaternionic v3.0.0

Diff since v2.0.1

Breaking changes

Replaced Base.eltype with Quaternionic.basetype. If you used the eltype to get the underlying number type of any quaternionic type before, you should now use basetype, which is exported from this package. This solves some obscure broadcasting problems.
The conj and unary - functions will no longer re-normalize when acting on Rotors. This simplifies and improves floating-point behavior.
The align function now specifies the input types; they must either be vectors of QuatVec or vectors of Rotor. Previously, the latter method would accept any types, which could lead to incorrect results. In particular, it is easy to accidentally promote a QuatVec to Quaternion, which would switch methods and thus use the wrong algorithm.

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, rather than regular values. Derivatives with those packages should now be accurate to first and possibly second order.

Quaternionic - 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.
