This file is here to allow devs to easily add stuff in the release notes for the next release, it allows easy syncing with the release team, since you don't have to be around when the release takes place... Just dump whatever you want to have mentioned in the release notes here. Please take care that it is in a way that allows copy&paste to the release notes. That is making sure that spelling/grammer/whatever is usable and that you are using complete sentences, not just single words. The release team should empty this file after each release. Terrain graphic rules for user-made add-ons are now loaded before the core ones, making custom tiles look the same in-game as they did in the editor in the previous release (1.5.2). Editor2 is the new map editor developed by Ilor as the GSoC project. Editor2 is a replacement of wesnoth_editor, the old_editor. Unlike the old editor, editor2 is compiled in the game executable. The old editor remains in its own executable, both can safely coexist. To build the game with the new editor, use scons with editor2=yes or an equivalent option in the other build systems (--with-editor2). This option is enab;ed by default. Remember that you need to build the game, not the editor target -- wesnoth_editor is the largely unmodified old editor. If building manually, you must define the USE_EDITOR symbol and add the editor2 sources to the build. The USE_EDITOR2 symbol does not affect building of the old editor. To start the new editor, launch wesnoth.exe and choose "Editor" in the title menu, or use the -e or --editor command line option, i.e. "wesnoth -e". If this fails and there is no "Editor" button, it means the game was compiled without editor2 support.
