  • South Mountain added 4/24/2015 (1.00)
  • South Mountain revised 5/5/2017 (1.01)
  • South Mountain revised 3/30/2019 (1.2)
  • Cedar Mountain added 11/06/15, with a similar graphic and design package as South Mountain.

South Mountain revised 3/30/19

  • CSA Macbeth battery was missing; this has been added to relevant scenarios
  • Four battalions of the Union Hartsuff Brigade were missing: 11PA a, 11PA b, 83NY a, and 83NY b; these have been added to relevant scenarios

South Mountain revised 5/5/17

  • Fatigue Level "OK" was missing from Brigadier counters; this was corrected
  • Added a toggleable SP counter as an optional marker for those wanting to better replicate physical play
  • Some markers combined, such as May/Must Advance, Refuse Left/Right

Cedar Mountain updated to 2.02 4/4/16 to address a few small issues and to consolidate/reduce markers.

  • 6VAa regiment dismounted now has a disordered side
  • Cavalry regiments have their own Charge! and Blown markers (as they can act independently of their parent brigade)
  • Deployment markers now cast an "area of effect" to aid in set-up
  • Attack and March orders "markers" created for use with independent cavalry regiments
  • Overmove layer added for Corps commanders; toggle on when a Corps Cmdr exceeds his 10MP allowance to retain their influence radius, the radius notation will be changed to 0.
  • Each side now has its own movement trail color.

Cedar Mountain v2.21: Fixed a few more marker issues (some not rotating when flipped); Banks' counter still not cooperating, however.

Cedar Mountain v2.20: Fixed a bunch of issues: Replaced Banks' counter (wasn't rotating properly); fixed two CSA dismounted cavalry units, whose disordered sides would not display; fixed mouseover not showing SP markers; added an Abandoned Guns counter to reflect latest series rules; Added a consolidated Orders counter for use on map (not on Brigadiers); now toggles through Attack, Advance and March.

Cedar Mountain v2.10: Added a Strength Point marker, which can incremented to reflect either current unit strength or losses. For that "just like a physical copy" play (at the cost of map clutter and larger stacks)
