Dear all,

I have prepared draft JEPs for the following features from Project Amber that we propose to preview in JDK 24:

-   Flexible Constructor Bodies (Third Preview) 
    https://openjdk.org/jeps/8338287

-   Implicitly Declared Classes and Instance Main Methods (Fourth Preview) 
    https://openjdk.org/jeps/8335984

-   Module Import Declarations (Second Preview) 
    https://openjdk.org/jeps/8335987

I emphasise that these are all drafts, but please send any feedback/comments to this list or direct to me.

Many thanks,
Gavin

PS: Aggelos has already announced the draft JEP for a further Project Amber feature:

Primitive Types in Patterns, instanceof, and switch (Second Preview)
