Note: This blog post is from 2023. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.

TLDR: The new updates are 1.8.0_381 (aka 8u381), 11.0.20, 17.0.8, and 20.0.2 respectively). For more on each of them, including what changed and the security fixes they each contain (including their CVE scores regarding urgency of concerns), see the Oracle resources I list below. Oracle calls them "critical patch updates" (yep, CPU), but they are in fact scheduled quarterly updates, so that "critical" nomenclature may sometimes be a bit overstated. And as is generally the case with these Java updates, most of them have the same changes and fixes across the 4 JVM versions, though not always.

For some folks, that's all they need to hear. For others, read on.
