I kept STM8 eForth stable for a long time but now there is a good reason for preparing a new release:

For the current work on a very lightweight MODBUS Server in STM8 eForth I needed some data from the target (e.g. clock frequency), and some other aides for low-level programming (e.g. an easy to use and stable interface between Forth and machine code).

The implementation of MODBUS in Forth is a pleasant experience: Moore's problem oriented language approach works quite well for embedded control and protocol implementations. I simply design the machine so that it implements layers of a protocol, and I do that in a language that describes the problem well. Thereby a language emerges, because my abstractions either describe the problem well, or I change it so that it describes the problem better.

It's safe to say that the implementation is very code efficient and highly functional at the same time (thanks to an interpreter-compiler on a MODBUS node).

Before the release of STM8 eForth 2.2.23, I'd like to improve the compilation of Forth code in the continuous integration environment.
