I've just converted some of my projects from EDT 0.8.1 over to EDT 0.8.2 and on the whole this was a pretty painless exercise on my small scale projects; mostly a case of changing class to cssClass (on my widgets) and then selecting the Organise Imports option within the source editor.

There was one additional step that I needed to perform on one of my record declarations and that was because of a change to the JSONName annotation implementation.

In EDT 0.8.1 I had ...

OpenPrice float {JSONName = "Open"};

For EDT 0.8.2 I had to change the line to this ...

OpenPrice float { @JSONName { "Open" } };

This got me thinking (a rare occurrence these days) ... what are annotations? how should I use them and can I create my own?

They look like a method of assigning additional properties to parts but does anyone know of any documentation that will give me an overview of the topic.

Richard,

You can find more information on annotations here - http://wiki.eclipse.org/EDT:Language_Overview02

As you discovered, we have removed a short hand notation for specifying an annotation in .8.2, as indicated here - http://wiki.eclipse.org/EDT:The_Differences_between_EDT_0.8.2_and_EDT_0.8.1

You can define your own annotations, but they will only be useful if you extend the compiler and the generator to use the annotation in some way.
