The help file states that the component will be shareware. It is not true anymore: it will stay as freeware - I do not have the tools right here to modify the help file. 

Developments of the button are at the moment suspended due to personal reasons. It will be finalized, but I can not commit on a date. 

However, the beta seems stable enough for use in production. A problem might arise when using real transparency (boTransparent). There seems also to be a bug in D3's TBitmap palette realization (confirmed by other sources).
