Cell ➞ Java compiler version 0.4.4
Version 0.4.4 of the Cell to Java code generator is now available. It brings a number of bug fixes and a couple new features.
The first one is a standard representation and syntactic sugar for characters, dates and time. The details are explained in the data chapter.
The second one is the ability for a relational automaton to send messages to other automata it is wired to, which is explained in the chapter on updates.
Among the bug fixes one is especially important as it fixes a compiler crash in the presence of certain types of foreign keys, so if you're using any of the 0.4.X (with X < 4) versions you should should upgrade right away.
