v1.4.0

This was the last version released under the MIT License. Every
version after v1.4.0 is proprietary — see LICENSE in the current
source. This zip is a compiled binary only; it does not contain or
expose the MIT-era source code.

Note: the original git commit history for this and earlier versions
was replaced with a single fresh commit after this release was
published, so the source now visible under the v1.4.0 tag is the
current (post-history-rewrite) codebase, not what was actually
compiled into this release's zip at the time. This page and its
downloadable asset remain as the historical record of the last MIT
release.
