The current (as of 2-October-2019 15:00 EDT (eastern US)) download page does not offer 5.3.3.62 for download - latest available release is 5.3.2.77 - is this an oversight? or has 5.3.3.62 been pulled for some reason?
5.3.3.62 IS available as an upgrade option from a running 5.3.2.77 instance, so it’s not completely gone, but… if you want to be running 5.3.3.62… that’s an extra step
