 # New Features
 
-## Lobby shuffle added as Intensity level 3
+## Shopsanity
 
-* Standard notes: 
-	* The sanctuary is vanilla, and will be missing the exit door until Zelda is rescued
-	* In entrance shuffle the hyrule castle left and right exit door will be missing until Zelda is rescued. This
-		replaces the rails that used to block those lobby exits
-	* In non-entrance shuffle, Agahnims tower can be in logic if you have cape and/or Master sword, but you are never
-		required to beat Agahnim 1 until Zelda is rescued.
-* Open notes:
-	* The Sanctuary is limited to be in a LW dungeon unless you have ER Crossed or higher enabled
-	* Mirroring from the Sanctuary to the new "Sanctuary" lobby is now in logic, as is exiting there.
-	* In ER crossed or higher, if the Sanctuary is in the Dark World, Link starts as Bunny there until the Moon Pearl
-		 is found. Nothing inside that dungeon is in logic until the Moon Pearl is found. (Unless it is a multi-entrance
-		  dungeon that you can access from some LW entrance)		 
-* Lobby list is found in the spoiler
-* Exits for Multi-entrance dungeons after beating bosses now makes more sense. Generally you'll exit from a entrance
-	from which the boss can logically be reached. If there are multiple, ones that do not lead to regions only accessible 
-	by connector are preferred. The exit is randomly chosen if there's no obvious preference. However, In certain poor
-	 cases like Skull Woods in ER, sometimes an exit is chosen not because you can reach the boss from there, but to
-	 prevent a potential forced S&Q.
-* Palette changes:
-	* Certain doors/transition no longer have an effect on the palette choice (dead ends mostly or just bridges)
-	* Sanctuary palette used on the adjacent rooms to Sanctuary (Sanctuary stays the dungeon color for now)
-	* Sewer palette comes back for part of Hyrule Castle for areas "near" the sewer dropdown
-	* There is a setting to keep original palettes (--standardize_palettes original)
-* Known issues:
-	* Palettes are not perfect 			
-		* Some ugly colors
-		* Invisible floors can be see in many palettes		
+--shopsanity added. This adds 32 shop locations (9 more in retro) to the general location pool.
 
-## Key Drop Shuffle
+Multi-world supported. Thanks go to Pepper and CaitSith2 for figuring out several items related to this major feature.
 
---keydropshuffle added. This add 33 new locations to the game where keys are found under pots
-and where enemies drop keys. This includes 32 small key location and the ball and chain guard who normally drop the HC
-Big Key. 
+Shop locations:
+* Lake Hylia Cave Shop (3 items)
+* Kakariko Village Shop (3 items)
+* Potion Shop (3 new items)
+* Paradox Cave Shop (3 items)
+* Capacity Upgrade Fairy (2 items)
+* Dark Lake Hylia Shop (3 items)
+* Curiosity/Red Shield Shop (3 items)
+* Dark Lumberjack Shop (3 items)
+* Dark Potion Shop (3 items)
+* Village of Outcast Hammer Peg Shop (3 items)
+* Dark Death Mountain Shop (3 items)
 
-* Overall location count updated
-* Setting mentioned in spoiler
-* Minor change: if a key is Universal or for that dungeon, then if will use the old mechanics of picking up the key without
-an entire pose and should be obtainable with the hookshot or boomerang as before
+Item Pool changes: To accommodate the new locations, new items are added to the pool, as follows:
 
-## --mixed_travel setting
-* Due to Hammerjump, Hovering in PoD Arena, and the Mire Big Key Chest bomb jump two sections of a supertile that are
-otherwise unconnected logically can be reach using these glitches. To prevent the player from unintentionally
-	* prevent: Rails are added to the 3 spots to prevent these tricks. This setting is recommend for those learning
-	 crossed dungeon mode to learn what is dangerous and what is not. No logic seeds ignore this setting.
-	 * allow: The rooms are left alone and it is up to the discretion of the player whether to use these tricks or not.
-	 * force: The two disjointed sections are forced to be in the same dungeon but performing the glitches is never
-	  logically required to complete that game.
+* 10 - Red Potion Refills
+* 9 - Ten Bombs
+* 4 - Small Hearts
+* 4 - Blue Shields
+* 1 - Red Shield
+* 1 - Bee
+* 1 - Ten Arrows
+* 1 - Green Potion Refill
+* 1 - Blue Potion Refill
+* 1 - +5 Bomb Capacity
+* 1 - +5 Arrow Capacity
 
-## Keysanity menu redesign
+1. Initially, 1 of each type of potion refill is shuffled to the shops. (the Capacity Fairy is excluded from this, see step 4). This ensures that potions can be bought somewhere.
+2. The rest of the shop pool is shuffled with the rest of the item pool. 
+3. At this time, only Ten Bombs, Ten Arrows, Capacity upgrades, Small Hearts, and the non-progressive shields can appear outside of shops. Any other shop items are replaced with rupees of various amounts. This is because of one reason: potion refills and the Bee are indistinguishable from Bottles with that item in them. Receiving those items without a bottle or empty bottle is essentially a nothing item but looks like a bottle. Note, the non-progressive Shields interact fine with Progressive Shields (you never get downgraded) but are usually also a nothing item most of the time.
+4. The Capacity Fairy cannot sell Potion Refills because the graphics are incompatible. 300 Rupees will replace any potion refill that ends up there.
+5. For capacity upgrades, if any shop sells capacity upgrades, then it will sell all seven of that type. Otherwise, if plain bombs or arrows are sold somewhere, then the other six capacity upgrades will be purchasable first at those locations and then replaced by the underlying ammo. If no suitable spot is found, then no more capacity upgrades will be available for that seed. (There is always one somewhere in the pool.)
+6. Any shop item that is originally sold by shops can be bought indefinitely, but only the first purchase counts toward total checks on the credits screen & item counter. All other items can be bought only once.
 
-Redesign of Keysanity Menu complete for crossed dungeon and moved out of experimental.
-* First screen about Big Keys and Small Keys
-	* 1st Column: The map is required for information about the Big Key
-		* If you don't have the map, it'll be blank until you obtain the Big Key
-		* If have the map:
-			* 0 indicates there is no Big Key for that dungeon
-			* A red symbol indicates the Ball N Chain guard has the big key for that dungeon (does not apply in 
-			--keydropshuffle)
-			* Blank if there a big key but you haven't found it yet
-	* 2nd Column displays the current number of keys for that dungeon. Suppressed in retro (always blank)
-	* 3rd Column only displays if you have the map. It shows the number of keys left to collect for that dungeon. If
-	--keydropshuffle is off, this does not count key drops. If on, it does.
-	* (Note: the key columns can display up to 35 using the letters A-Z after 9)
-* Second screen about Maps / Compass
-	* 1st Column: indicates if you have found the map or not for that dungeon
-	* 2nd and 3rd Column: You must have the compass to see these columns. A two-digit display that shows you how
-	many chests are left in the dungeon. If --keydropshuffle is off, this does not count key drops. If on, it does. 
-	
-## Potshuffle by compiling
+All items in the general item pool may appear in shops. This includes normal progression items and dungeon items in the appropriate keysanity settings.
 
-Same flag as before but uses python logic written by compiling instead of the enemizer logic-less version.
+#### Pricing Guide
 
-## Other features
+All prices range approx. from half the base price to the base price in increments of 5, the exact price is chosen randomly within the range.

-* In crossed mode, the new dungeon is listed along with the location designated by a '@' sign
-* Random gt crystals and ganon crystal are noted in the settings for better reproduction of seeds
+In addition, 4-7 items are steeply discounted at random.
 
-### Experimental features
+#### Rupee Balancing Algorithm
 
-* Only the item counter is currently experimental
-	* Item counter is suppressed in Triforce Hunt
+To prevent needed to grind for rupees to buy things in Sphere 1 and later, a money balancing algorithm has been developed to counteract the need for rupees. Basic logic: it assumes you buy nothing until you are blocked by a shop, a check that requires money, or blocked by Kiki. Then you must have enough to make all purchases. If not, any free rupees encountered may be swapped with higher denominations that have not been encountered. Ammo may also be swapped, if necessary.
 
-#### Temporary debug features
+(Checks that require money: Bottle Merchant, King Zora, Digging Game, Chest Game, Blacksmith, anything blocked by Kiki e.g. all of Palace of Darkness when ER is vanilla)
 
-* Removed the red square in the upper right corner of the hud if the castle gate is closed  
+The Houlihan room is not in logic but the five dungeon rooms that provide rupees are. Pots with rupees, the arrow game, and all other gambling games are not counted for determining income.
 
-# Bug Fixes
+Currently this is applied to seeds without shopsanity on so early money is slightly more likely if progression is on a check that requires money even if Shopsanity is not turned on. 
 
-* 2.0.20u
-	* Problem with Desert Wall not being pre-opened in intensity 3 fixed 
-* 2.0.19u

+#### Retro and Shopsanity
+
+9 new locations are added.
+
+The four "Take Any" caves are converted into "Take Both" caves. Those and the old man cave are included in the shuffle. The sword is returned to the pool, and the 4 heart containers and 4 blue potion refills are also added to the general item pool. All items found in the retro caves are free to take once. Potion refills will disappear after use.
+
+Arrow Capacity upgrades are now replaced by Rupees wherever it might end up.
+ 
+The Ten Arrows and 5 randomly selected Small Hearts or Blue Shields are replaced by the quiver item (represented by the Single Arrow in game.) 5 Red Potion refills are replaced by the Universal small key. It is assured that at least one shop sells Universal Small Keys. The quiver may thus not be found in shops. The quiver and small keys retain their original base price, but may be discounted.
+
+##### Misc Notes
+
+The location counter both experimental and the credits now reflects the total and current checks made. Original retro for example is 221 while shopsanity by itself is 248. Keydropshuffle+sanity+retro can reach up to 290.
+
+## In-Room Staircases/Ladders
+
+In intensity level 2 and higher the in-floor staircases/ladders that take you between tiles can now be shuffled with
+any N/S connections. (those that appear to go up one floor are North connection and those that go down are South ones)
+
+Big thanks to Catobat for doing all the hard work.
+
+## Enemizer change
+
+The attic/maiden sequence is now active and required when Blind is the boss of Theives' Town even when bosses are shuffled.
+
+## Settings code
+
+File names have changed with a settings code instead of listing major settings chosen. Mystery games omit this for obvious reasons. Also found in the spoiler.
+
+Added to CLI only now. With more testing, this will be added to the GUI to be able to save use settings codes for generation. 
+
+## Mystery fixes
+
+The Mystery.py file has been updated for those who like to use that for generating games. Supports keydropshuffle, 
+shopsanity, and other settings that have been added.
+
+## Experimental Item Counter
+
+New item counter modified to show total
