semver v2.0.4

A patch release that appears to be an identical version to v2.0.3.

(This release note was written long after the release. The exact reason for a v2.0.4 release is now unknown. However, git tags for the releases are on the same commit. In addition, the packages appear to be essentially identical except for the version numbers even down to the byte length of the DLLs and both list 02eb12743a as the commit hash in their product version)
