+-- Version 2.0-beta-16 - 2019-03-03
+--   Add support to specify lighting param2 in minetest.conf.
+--   This allows using lights such as moreblocks:slab_meselamp_1,20
+--   which gives a param2 = 20, so it's oriented properly on ceiling.
 -- Version 2.0-beta-15 - 2019-03-02
 --   MAJOR change with controls (see below for details).
 --   Support on_dignodes callbacks like used in borders mod for barriers.
