Changelog

1.1.1 - 2016/09/20

Added support for more "socketed gem" modifiers, particularly those from essences
Fixed a few minor issues

1.1.0 - 2016/09/20

You can now import all character data: passive tree, jewels, skills and items!
- Character import now has two options:
  - Passive Tree and Jewels: imports the passive skill tree and any jewels socketed into it
  - Items and Skills: imports all other equipped items, and any skills socketed into them
- When importing to an existing build:
  - The passive tree will be replaced with the imported one
  - Items (including jewels) will be added to the build, unless the item was added by a previous character import
    - If you've previously added an item by copying it from ingame, the character import will still add it, so you'll need to delete the old items after the import
  - Skills will be added if no existing skill matches the new one ('match' meaning the same gems in the same order)
- The only data that cannot be imported is the bandit choices, as these aren't available from the API
Several improvements have been made to the Skills system:
- You can now specify multiple active gems in a single skill setup (now referred to as a socket group)
- Hovering over an active gem will highlight the support gems which are applying to it, and hovering over a support gem will highlight the active gems that it applies to
- The skills system should now be much more accurate at determining which supports can apply to active skill gems
- Supports granted by an item are now automatically applied to any skills socketed in that item
  - Any such supports that you've added manually will be ignored due to the next change:
- Multiple copies of support gems are now handled correctly (only the gem with the highest level is used)
Modifiers that depend on the absence of enemy status effects should now only apply in effective DPS mode
Passive tree search now highlights using a red circle instead of flashing
Updated the passive skill tree data

Now shows "Removing this item will give you" section for all items, not just jewels
You can now equip items from both the "All Items" list and the uniques/templates list by Control+Clicking the item
- If there's two slots the item can go in, holding Shift as well will equip it in the second slot instead
- Jewels cannot be equipped in this way (since it'll probably put them in the wrong socket) but they will still be added to your build if you Ctrl-Click them in the uniques or templates lists
