• fix: a nested false, 0 or '' is now returned when a flat key with the same dotted name also exists. With { a: { b: false }, 'a.b': 'flat' }, getResource('en', 'translation', 'a.b') and t('a.b') returned 'flat': the nested result was checked for truthiness, so these present values fell through to the flat-key lookup. Without such a flat key they were already returned. A nested null, which is not a valid lookup by default (returnNull: false), still falls back to the flat key. Thanks @lprnmns (#2461).
