re-running tests now that yesterday's data issue seems to be resolved.

Failure on windows actually looks related:

Suggested change

	VERSION_PATTERNS = [r"([0-9]+\.[0-9]+\.[0-9]+)[a-z\n\n]*ttyd"]
	VERSION_PATTERNS = [r"([0-9]+\.[0-9]+\.[0-9]+)[a-z\n\r]*ttyd"]

My guess is that windows is complaining about lack of \r here.

Good catch, I updated PR

Merge time. Thanks!
