a bunch of the e18e community have been working pretty hard to upgrade high impact projects etc, but its a slow job

quite a few projects were blocked until they could continue supporting globs too. but with the release of tinyglobby, thats a lot easier now (to just pass tinyglobby globs into chokidar)
