ASM 8.0(.1) being released now, we're anticipating ASM 9.0 to be picked up in Spring Framework 5.3, turning record support non-experimental for JDK 15 and introducing early JDK 16 support.
Our 5.2.x line is currently on ASM 7.3.1 (#24438) and will likely stay on that branch, with record support remaining experimental (#24722) for the time being.

There seem to be no plans for an ASM 8.1 release anymore, going straight to ASM 9.0 instead. We'll align for 5.3 M2.
