Version 2.2 Changes:

• (STT) Fixed broken starting cloaking device tech in Split Tech Tree
  
• (STT) Choosing the terraforming starting tech will now complete Biology V automatically when it is reached in the tech tree. This fix causes some minor issues with the tooltip for that perk on the custom race screen.
  
• (STT) Advanced starting age now starts you at Biology IV instead of Biology V
  
• (STT) Sociology XIII is now a choice between galactic currency exchange and galactic command center

Version 2.1 Changes:

• Fixed hyper advanced starting age not giving Chemistry
  
• Increased Orion technology research point score for proper blueprint upgrading
  
• Increased RP costs of levels II through V to match 5X 5.3 Tech Tree curve change
  
• Fields III: Fusion beam is now part of the choice, making it now possible in STT to skip all the beam techs
  
• Power IX: Neutronium bomb is no longer part of the choice
  
• Construction XI: Now offers a choice between Advanced City Planning and Star Fortress
  
• Power XII: Now offers a choice between Chromodynamic Bomb and Hyper Advanced Colony Ship

Version 2.0: Major update to catch up to recent 5X changes. A lot of techs moved. Also now optionally DSMP compatible if you load in the order 5X, UCP, DSMP, 5XCPC, STT. Use with 5X v5.0 or later and UCP 6.2 or later.

Version 1.8: Updated with 5X techs from v4.3.0. Finally added some icons to tech nodes, though I was a bit lazy and didn't really customize them to individual tech nodes. v1.8a: Fixed a bug causing which was preventing core waste dump from acting as an upgrade to pollution processor.

Version 1.7: Moved military outposts later in the tree to match the last 5X update. Added Spanish language support. 1.7a: Fixed a bug.
