-New/changed features:
+================================================
+Release 13.6: 17 November 2023
+
+Bugfixes:
 - make.rb prints a warning if undo support was requested but game is z5-z8 and doesn't support undo.
 - Build using -P didn't work, probably since v13.0. Fixed.
 - make.rb didn't protest when asked to build with Undo in mode P, though it's not possible. Now it halts with an error.
 - make.rb would sometimes reserve too small a buffer for splash screen in mode P.
 - make.rb couldn't build a mode P game using the full memory if the story file had an odd number of pages, e.g. a game of 51.25 KB couldn't be built even if a 51 KB game left an empty memory page at the end.
