Apologies if this has been asked already (and I would have expected it to be - however, my search, perhaps less than competent, could not locate it) but has a detailed list of the changes to the rules of DBA from previous versions to the new V3 been published?
Here is a document I prepared for folks making the transition from 2.2 to 3...
DBA 2.2 to 3.0 Important Safety Tips:
Terrain Placement: The board is divided into quarters... Defender picks terrain and places compulsory first. 1-4 Place on that board quarter. 5 Defender picks, 6 Attacker picks. 1 BW from another terrain piece and 1BW from board edge. Gentle hills may cross one boundary. Plough must.
Terrain: Good going, bad going, and rough. Rough is not good going. No combat penalty, but no rear or side support. Watch out for combat outcomes.
Setup: At least 3 BW from the center. LH, Cav, Ps, Ax, Mtd-Inf must be at least 2 BW from a side edge. Other must be 4 BW.
Start: No swaps. Defender moves 1st. On a "1" Plough changes from "Good Going" to "Rough Going".
Movement: Measure from the front corners. Psiloi can make 2 moves on turn one and any turn that the first move starts in good going and the second move ends in bad going. LH can move 3 times. Any on road may make any number of moves. Must be a full move. 1st is free.
Conforming: Single elements conform to groups. Non-bounding player's conform is automatic and free.
Turning to face: Elements turn to face flank contact unless also contacted to the front. Second rank elements follow the front elements. If the front rank doesn't turn, the second doesn't.
Distance Combat: Bows fire 3 BW. Arc is 1BW to each side. Target must present .5BW or complete element edge (think flank). Bow may not fire if they moved over 1BW.
Support: Pikes, Warband, and LH get rear support. Spear gets side support from spear and blade. (Solid only) Bows get side support from Blades. (only if both Solid) LH gets rear support from LH (Watch the flee move!)
Special Factors: Ps are not counted as overlapped by corner to corner contact.
Close Combat: Fast recoil from Solid on ties. Lb & Cb kill Knights on ties. Bd kill knights on ties. 4Kn recoils from 3Kn on ties.
Recoils: Elements flanked that suffer recoils are killed instead. Elements that can't start their recoil die. Others recoil until stopped.
Pursuit: Blades, Pikes, Warband pursue foot except Ps 1/2 BW. Units do not pursue if they would enter Bad Going. Please note..."Enter". 3Kn, Hd, Scythed Chariots pursue 1 BW vs all. Units do not pursue if they would enter Bad Going. Please note..."Enter".
Double Based Elements: Double based units... If in good going +1 in close combat vs foot. 1st one destroyed counts as 2 elements dead.
