What versions exist of MIDP and CLDC?

At the time of writing, there were two versions of CLDC: 1.0 and 1.1. Version 1.1 is a significant enhancement over 1.0, and includes more sophisticated memory management and floating point support. The latest version of MIDP is 2.0 (also called `MIDP-NG’) which is, again, a significant enhancement over 1.0. Unfortunately, MIDP2.0 support does not require CLDC1.1, only CLDC1.0. So MIDP2.0 applications cannot take advantage of the new CLDC1.1 features, or at least cannot do so in a portable way. This situation is likely to persist, because the hardware requirements for supporting MIDP2.0 are actually somewhat less than for supporting CLDC1.1. As a result, there are MIDP2.0 mobile phones that could probably not support CLDC1.1. At the time of writing (Spring 1993) there are relatively few MIDP2.0 devices on the market, and most developers are still targeting MIDP1.0.
