1.19.18 has been released! This has a couple major campaign changes, with both the new Dusk of Dawn campaign being added as a short Novice difficulty Troll campaign as well as the heavily revised Heir to the Throne being added. The original Heir to the Throne has been renamed “Heir to the Throne, Classic” and the original Battle Training tutorial has been merged into it.

As usual, for more details see https://r.wesnoth.org/t60291
