When checking for updates I noticed that when I have 'offer upgrade to Beta versions' enabled, the response shows the latest version as 4.6.20171.14978 [03/22/2017].
I disabled checking for beta versions and it returned the latest released version ( 5.0.20181.14850 [03/20/2018] ).
Not sure if this is intentional or a bug. Just thought I'd point it out.
