CHANGES.md

@@ -15,10 +15,6 @@ Fixes:
  - 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:
 
@@ -28,9 +24,6 @@ Performance:
  - 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

  - Added bar on the interface terminal that search by inputs ( The one on the LEFT, also searchs by interface name )

  - 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 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)
