                PROCESSING 2.0a7 (REV 0206) - 29 July 2012 Hopefully the last alpha before we hit 2.0 beta. The big change is that we're dropping support for applets in 2.0, and in this release. See the Changes section of the Wiki for details. We've not updated all of the documentation to reflect this yet.
               
              
 

Wrong Sub-Forum, btw. This isn't about how to share your work, but about actually displaying, linking your work.

Oh darn, and oh darn. Thanks for the quick reply.

For me, it looks like an unfortunate decision. Making applets is hard to get right, and there were lot of issues with the way they were displayed in Processing.org (but not necessarily elsewhere) and it is hard to do with OpenGL (which becomes quite pervasive in 2.0).
But dropping this historical support (Processing is (or was?) build around an applet base) is bold, as the demos of the site are based on this (but I suppose they will switch to PJS as most of them are simple) and sites like OpenProcessing revolves around this technology.
Processing.js can be used in most cases where applets were used, but that excludes all applets using advanced Java features or libraries.

Looking at the detailed change list, they confirm my suspicions: support for applets is dropped just for the same reasons that P2D and P3D support is dropped: too much work (and lack of support from browsers). I suppose people using advanced features or libraries can still make their applet by hand, but that's annoying none less.

On the other hand, delay() is back? Bad choice IMHO. Since it is needed in the serial library, they could have made a Serial.delay() and be done with it.

While there were at making deep, incompatible changes, they should have changed all constants to be enums... That would avoid people trying to call textMode(CORNERS) and complaining it doesn't work as expected... :-)
