What's the difference between PocketSphinx 0.1.15 and 5.0.4?

[ftnext]

Steps to reproduce

1. pip install pocketsphinx==5.0.4
2. pytest tests/test_special_features.py

Expected behaviour

Test passes

Actual behaviour

The test will not pass unless you modify as follows

speech_recognition/tests/test_special_features.py

Lines 21 to 24 in 34e72fe

	# pocketsphinx < 5 recognizes tree but pocketsphinx >= 5 ignores it (TODO need to research why)
	self.assertEqual(r.recognize_sphinx(audio, keyword_entries=[("wan", 0.95), ("too", 1.0), ("tree", 1.0)]), "too wan")
	# pocketsphinx < 5 recognizes tee but pocketsphinx >= 5 ignores it (TODO need to research why)
	self.assertEqual(r.recognize_sphinx(audio, keyword_entries=[("un", 0.95), ("to", 1.0), ("tee", 1.0)]), "to un")

In PocketSphinx 0.1.15, it passed without modification. What's the difference?
