-Incursion (open source) 0.6.9Y20: 2015-??-??
+Incursion (open source) 0.6.9Y20: 2024-??-??
+* https://github.com/rmtew/incursion-roguelike/issues/27: The code assumed that on a day passing there would never be more than 2048 objects per map. Popo McTroll reported on Julian's old email list that he managed to get this upwards of 3000. The code should now handle whatever number have accrued. Fixed by https://github.com/HexDecimal.
 * https://bitbucket.org/rmtew/incursion-roguelike/issues/244/: Consistency changes and fixes to spelling throughout the game text.  This also renames the Flat-Footed concept to Off-Guard, inspired by the notion snakes and other creatures may not have feet to be flat.  Pull request from Dave Duckett.
 * https://bitbucket.org/rmtew/incursion-roguelike/issues/246/: The build.bat script has been upgraded significantly. It now supports 'build-project'/'-bp' which replaces the old never implemented 'project'/'-p'.  And it also supports user functions, which are dynamically handled along with the standard ones, and it's used for 'compile-scripts'/'-cs' which can of course be used to compile 'Incursion.mod'.  This might currently be the only way to compile the scripts.
 * https://bitbucket.org/rmtew/incursion-roguelike/issues/248/: Incursion now has an x64 configuration and with minor complications compiles and starts up.  Note that there are a lot of compilation warnings, so stability is questionable.  The x64 compilation requires some finessing, as modaccent is a very dated codebase that crashes hard when run as an x64 executable.  But the Win32 binary does exactly the same thing.  The exe_curses project is disabled for x64, as it only comes able to compile for Win32.  As it's not really usable, this isn't much of a loss.

- 6. FAQ.
-
-Introduction
-============
-
-Incursion is a fantasy roguelike where you play as an adventurer in a dungeon.
-Help is provided in-game, along with copious amounts of detail.
-
-This version is a continuation of the open source release of 0.9.6H4,
-which it should be noted is earlier than the last official binary release
-of 0.6.9I.  The missing differences are unknown.
-
-Support the development
-=======================

-
-Project goals
-=============
-
-To fix bugs and where the original intention is clear, implement missing
-functionality.
-
-This is a beta release of something you did not pay money for.  Use it at your
-own risk, and exercise your right to not use it if it makes you unhappy.
-
-When the beta is sufficiently stable and complete, an alpha line 0.6.9Z
-will be released.  After a period of time, an official release will be
-made of a 0.7 version.  
-
-Source code
-===========
-
-You can find the source code in a git repository hosted on bitbucket:
-
-  https://bitbucket.org/rmtew/incursion-roguelike/
-  
-
-Reporting problems
-==================
-  
-Issues can be reported to the bitbucket issue tracker:
-
-  https://bitbucket.org/rmtew/incursion-roguelike/issues?status=new&status=open
-
-Frequently asked questions
-==========================
-
- Q. When I press a movement key, it sends two keypresses?
- A. Turn off numlock. You are using a keypad on a full keyboard.  SDL2 does not support differentiating between number keypad presses, and number key presses.
