I've tested using that version of the code for more than 2 months without issues.
SASL authentication feature has been tested in PLAIN mode and EXTERNAL with an SSL cert fingerprint. Also, it has been tested with multiple username/password lengths, including the ones triggering the specific cases (when the base64 SASL authentication challenge is exactly of 400 chars).
