Feature: Added toggles for normal rooms, mini-boss rooms, and I AM ERROR rooms. All are turned off by default.
Enhancement: Significant code optimizations. Several computations that were being performed constantly are now only performed once upon entering a room for the first time. I also have a better system for handling all of the options, so I should be able to add more things to check for in the future without any performance penalty.

Feature: Many more options are exposed in the Mod Config Menu, and options are now organized into categories: Modes, Rooms, and Tweaks. All of the game modes can be individually toggled on or off (including challenges), and a few additional rooms can now be individually toggled: treasure, curse, and challenge rooms.
Enhancement: The mod now only loads if you have Repentance installed. It probably didn't work with AB+ anyways, so this should prevent AB+ players from having issues if they happen to subscribe to this mod for some reason.

Feature: Secret room support. Disabled by default, but if enabled in the Mod Config Menu will provide additional item spawns in secret rooms, super secret rooms, and ultra secret rooms.
Enhancement: The mod should now remember your Mod Config Menu settings when closing and reopening the game. NOTE - you will have to reconfigure your settings each time the mod is updated.
Bugfix: The Mom's Cellphone mod should now work properly with BCTR.
Bugfix: Fixed an edge case that triggered by possessing multiple doppleganger items at once.

Enhancement: When "Top items are never active items" is enabled, players should no longer briefly see the first active item before it morphs into a passive item. The functionality hasn't changed, but it was bothering me that the transition wasn't seamless. Now it is!

Bugfix: Oops, forgot to change a variable name. Void/Abyss fix should now actually work.

Bugfix: The last update made Strawman stop counting as an extra player, but I forgot that it's technically possible to obtain more than one Strawman on the same character. The mod didn't account for this correctly. It now shouldn't matter how many instances of Strawman or Found Soul the players are holding, the correct number of items should spawn accordingly.

Feature: Spawning extra items for dead players is now an option that can be turned on (off by default) in the Mod Config Menu.
Feature: Enabling the Void fix now also fixes Abyss, Tainted Apollyon's active item. The Mod Config Menu's option description has been changed to reflect this.
Bugfix: Holding the Strawman item no longer counts as an extra player.
Bugfix: Holding the Found Soul trinket no longer counts as an extra player.

Feature: When void (Apollyon's starting item) is activated and there are still more items to spawn in the current room, the item pedestal is no longer completely removed. This means that voiding the top item no longer prevents additional items from spawning in coop. This deviates from the vanilla game's boss room behavior, and can be toggled off in the Mod Config Menu.

Feature: Planetarium support, can be toggled off in the Mod Config Menu.
Feature: Prevent treasure room items from being active items, unless they are the last item in the stack. This prevents the annoying situation where all players already have an active item and can't access the additional item spawns. This deviates from the vanilla game's boss room behavior, and can be toggled off in the Mod Config Menu.
Bugfix: Extra items no longer spawn for dead players.
Bugfix: Extra items no longer spawn in the mirrored treasure rooms.

Feature: Allow users to enable/disable greed mode support if they have Mod Config Menu installed.
