Please could someone confirm the LibRaw version marking which should be displayed by an application using the 202403 snapshot?

I confess to being confused by LibRaw versioning. According to https://www.libraw.org/ "Minor updates (0.20.1, 0.20.2…) do not change the API/ABI and new cameras are not added; generally they are just bugfixes." Therefore I would expect 21.3 to just be a bugfix on 21.0.

To get support for newer cameras we need the "202403 Snapshot", but that number has no relation to the version numbers quoted above, and neither that page nor the main page states clearly what version number it should display.

Does anyone know definitely what version number we should be seeing?

Thanks
Andrew
