+Changes so far :
+
+Design changes/breakages:
+ - Interfaces no longer spill items of one pattern on other faces
+ - Interfaces now push patterns in round-robin (Interfaces, then sides)
+
+
+
+
+Fixes:
+
+ - Fix gregtech machines appearing with 'unnamed' or 'draconium lens' on the interface terminal on specific situations.
+ - Add memorycard support for fluid interfaces, import/export/storage busses and level emitters ( this fix was upstreamed to AE2 for MC 1.16)
+ - Storage busses now hide/show inaccessible items as configured.
+ - Exclusive Blocking mode for GTCE ( shapes, molds and configured circuits do not block GTCE machines )
+ - Blocking modes default to block on any item in the iventory the entity exposes
+ - Fuzzy includes items that report that they're damageable, but report a maxDamage of 0 ( auto-crafting of basic capacitors -> resonant capacitors is now possible ) <- Broken item implementation.
+ - Fix CME exceptions on the energy grid
+ - Fix AE going offline even with enough power by extracting from the local buffer always last
+ - Fix IO-Port copying craftable flag into items
+ - Fix NBT of old items not clearing on drives that reached 64 types once
+
+Performance:
+
+ - Added @talchas fixes for insane channelless AE networks.
+ - Implemented StorageDrawers slotless itemrepository.
+ - Removed CraftedEvent calls (really bad lag with craftweaker versions before CraftTweaker2-1.12-4.1.20.626)
+ - Count items set in interfaces before queuing crafting for them needlessly
+ - Backported b7ca98d ( Avoid copying items on simulated item extraction )
+ - Cache some level emitters functions
+ - Reduced import bus insert simulation to 1 before real insertion (if possible)
+ - Backported itemlist re-implementation along with pattern changes to avoid CraftingManager fallback issues
+ - Instead of recalculating all the content of the network on every change, track the changes properly and apply them to the cached list of items
+
+QOL:
+
+ - added highlight interface button to interface terminal ("?" button on the left of the interface slots)
+ - Added bar on the interface terminal that search by inputs ( The one on the LEFT, also searchs by interface name )
+ - Shortcut to molecular assemblers with free slots on the terminal interface by @Theisyat
+ - Toggle button on interface terminal to hide full interfaces
+ - JEI "U", "R" and "A" (Usages/Recipes/Bookmark) now work on the Crafting Status GUI. ( the one that shows the total items to craft, and whats missing)
+ - Patterns can now be made with items currently showing on JEI. ( This is overriden by Just Enough Energistics. )
+ - Added multiplier buttons to processing pattern gui
+ - Switched crafting terminal JEI search to fuzzy mode. If the recipe uses a damageable item, AE will try to grab it ( damaged tools )
+ - Encoded patterns stack up to 64 ( holding shift and clicking the encode arrow will transfer the encoded pattern to the player inventory)
+ - Encoded patterns can be draggred on the interface terminal.
+ - Storage Monitor and Conversion Monitor now also ccepts fluids
+ - Draggable JEI ghost items (also works on bookmarked items. SHIFT + Click will move the hovered item into the first free target slot)
+ - JEI auto switches between crafting and processing patterns
+ - GTCE Blocking mode work through phantom itemfaces
+ - Shift-clicking blank patterns into the pattern terminal will try to fill the blank pattern slots first
+ - Mismached simulated/real item count ( most often due to compacting drawers ) will now tell the player wich item cause the failure when trying to start a craft
+ - Added 'pattern expansion' cards that adds an extra row of patterns to interfaces. up to 3 card on an interface. (each card will increase the interface idle power draw by 4 times)
+
+HOTKEYS:
+
+ - Implemented mousetweaks API. AE2 custom keybinds now work. (Try right clicking and use the scroll-wheel on the terminals)
+ - Holding SHIFT and scrolling UP and DOWN will increase the items set on the configured slots of Interfaces and Pattern Terminal (Processing mode)
