Release 1.5.11 (for JOSM >= 13643) Mainly i18n and dependency/tooling updates. Adaptions to new JOSM API. New language Italian! Due to a breaking change in r13643, the minimum JOSM version has to be bumped to a later version than the current `tested` version. So this release is two-part for JOSM versions before and after this change (see a3b27111f3822dfc12cca551be1cc2494bb5af19).
