Full re-install is recommended because a lot files arrangement, also with smaller size. Works on an on-going savefile, but a lot had changed, it would be much enjoyable on a new playthrough tho.
Major update, including 200+ new files. Re-install are always recommended, because some files been rearranged, besides it only take few seconds. Recommended for a new playthrough for Heartland, if you haven't try it yet.
Small fixed and balancing, added/edited description to over 100 new files. Please check changelog for full detail. It's safe to 'replace' when update this new version on the previous version, or just fully reinstall, both works fine.
