Cannot install zstd 1.3.3 on win-64

This may be a conda-forge issue, but I'll start here. When trying to install zstd into an empty environment on Windows, I get the following.

(zstd-test) Z:\chambbj On My Mac\loki\pdal\build-conda>conda install -c conda-forge zstd
Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  - zstd
