Regardless, here is a verbatim extract from the Foreworld section of
ISO 15765-2:2024

This fourth edition cancels and replaces the third edition (ISO
15765-2:2016), which has been technically revised.

The main changes are as follows:

- restructured the document to achieve compatibility with OSI
7-layers model;

- introduced T_Data abstract service primitive interface to
achieve compatibility with ISO 14229-2;

- moved all transport layer protocol-related information to Clause 9;

- clarification and editorial corrections


Yes, I've checked the release notes on the ISO website too.
This really looks like editorial stuff that has nothing to do with the data
protocol and its segmentation.


The :2016 suffix is cited both here and inside the Kconfig. We can:
- keep the :2016 here and then update both the documentation and the
Kconfig once the standard has been checked
- move to :2024 both here and inside the Kconfig
- drop the :2016 from everywhere (leaving only ISO 15765) and move to
ISO 15765:2024 only inside the "Specifications used" paragraph

What do you think? Shall the modifications to the Kconfig be done as part of
this series?

So here is my completely new view on this version topic ... ;-D

I would vote for ISO 15765-2:2016 in all places.

The ISO 15765-2:2016 is the first ISO 15765-2 standard which supports CAN FD and ISO 15765-2:2024 does not bring any functional change neither to the standard nor to the implementation in the Linux kernel.

For that reason ISO 15765-2:2016 is still correct and relevant (due to the CAN FD support) and does not confuse the users whether the 2024 version has some completely new feature or is potentially incompatible to the 2016 version.

Best regards,
Oliver
