Huh, don't know why the GitHub Action didn't pick this up and update .ORG. Will have to investigate what's going on there.

@jeffpaul, you need to merge new commits from develop to master to get the action triggered for the current configuration.

name: Plugin asset/readme update
on:
  push:
    branches:
    - master

Nice catch @dinhtungdu, looks like there's a small update in the main plugin file so we'll get those changes into master in our next release version (likely one targeting the work from #40).
