We’ve just released our first beta of PraxisLIVE v5 at https://github.com/praxis-live/praxis-live/releases and would love to get some testing. PraxisLIVE is a live programming IDE and runtime for Java, and it includes Processing.
As part of moving PraxisCORE (the runtime) to Java 11 and the Java module system, as well as pushing to Maven, we’re currently using a fork of Processing (libp5x). This is using a much adapted form of the LWJGL renderer. I’d ideally like to see this improved and made available upstream, although the necessary changes were rejected from PApplet, so we’ll see. Be interesting to know what interest there is in that! And to know where it is and isn’t working.
