Compatibility with libxml2 2.14

[beenje]

I maintain the nexus conda package on conda-forge.

There is an opened PR to rebuild it with libxml2 2.14 but compilation fails:

I see the code was updated in 2020 to replace those deprecated functions (b0459f6) but there hasn't been any new release since 2016.

Is it possible to make a new release?
