Hello,

2019-03 is out
but
and the bottom of the pages it states Version 2019.01: 1st December 2018

is that correct?

RJC has stated that only individual lists with changes have the version bit updated when an update is released - in the case of the Greece & Macedon set this is just the mercenary Greek list.

The version numbers of each set are listed here https://mortem-et-gloriam.co.uk/smf/index.php?topic=312.0
