Version 1.4.3 is out, with Luna Lib integration, new settings, and bug fixes. This version requires version 0.5.3 of Variants Lib, so make sure to download that too. See the changelog for a fill list of details.
Need to point out that Better Variants 1.4.3 + VariantsLib 0.5.3 is
not save compatible with saves created with BV 1.4.2 + VL 0.5.2.
I kept a backup .zip archive with the previous versions, but it would have been nice to have been informed of said incompatibility.
Having said the above? I haven't tried changing the LunaLib settings from their (new) defaults.
Addendum: Also, the 'BetterVariants.version' file is malformed; it's missing a closing " mark at the end, which caused a CTD-during-game-asset(s)-load.
Even after correcting the local file, it won't compare properly against the online original, to 'prove' that BV v1.5.3 is the newest version.
