\item The \texttt{FE\_NedelecSZ} class that contains our
implementation of the N\'ed\'elec element using the orientation
scheme of \cite{Zag06} now supports the computation of hanging

Therefore, the sign-conflict that arises for hp quadrilateral and
hexahedral N\'ed\'elec elements in the presence of hanging edges
and hanging faces was addressed for the implementation details;

and $x_{15}$ are the values of the two adjacent degrees of freedom on
the parent edge that contains the hanging node); or they can be of

\texttt{Lazy<T>} is a class that supports the lazy computation and
initialization of variables. Its intended use is for member

not for all uses of an object. For example, all finite element classes
provide interpolation and restriction matrices to support multigrid
and other algorithms. One could (i) always compute and store these
approaches costs memory and compute time even though most places
where one creates a finite element object will not actually query
these matrices; the second of these approaches is costly in places

object holding the result, rather than at the place of use; and
because the holder object -- \texttt{std::future} -- can only be

Secondly, our previous choice to use an open source license with strong
copyleft was motivated by our hope that we receive back code contributions
from third parties. In practice, however, our observation over the
-last 10 years is that
-our choice of license has not helped achieve this goal: Copyleft only applies when a derived
-software is sold or published. But almost all of our code contributions are
-voluntary and come from individual contributors with an academic
-background, where these considerations do not apply.

We have thus decided to switch away from the LGPL v2.1 license towards a
more permissible license. We settled on the Apache License 2.0 with
