Thanks for pinging us @emmtre – It looks like we did the work, but it’s in master and the last release of 9.1.1 was patching the couple of regressions introduced in 9.1.0.
So far things are looking good for 9.1.1, so we’ll likely be ready to test/release the things we have in master soon.
@ben.turner Many thanks for the update, I was just curious but no big deal since you can update WP CLI manually. Any progress with the pull request to handle spaces in PHP binary path? I’m surprised by the low activity in the GitHub repro. You would expect a collective interest in solving identified bugs by all the contributors.
