To mention it again:
Nothing doesn’t do monthly security updates, they always have done bimonthly updates. The (2a) Plus is on an evenly month cycle - February, April, June and so on. So there won’t be a March update, but instead it will get an April update.
These security updates typically get released on the second half of a month, you can roughly expect it sometime within the third and fourth weeks this month. The following update then will be released sometime in June, since - again - the security patches are bimonthly.
