• [BREAKING] The calcArmor, calcToughness, and calcParry methods are now private - the appropriate properties should be accessed by system.stats.toughness.armor, system.stats.toughness.value, and system.stats.parry.value respectively. These properties were already accessible and were the correct avenue of access prior to this update. by @jpmeehan5
• The secondary parry value now represents system.stats.parry.shield instead of system.stats.parry.modifier, and operates like armor - it's a calculated field if parry is auto calculated on the Actor, otherwise it's manually editable. by @jpmeehan5
• [BREAKING] Folded system.stats.parry.modifier and system.stats.toughness.modifier into the existing system.stats.parry.value and system.stats.toughness.value with a migration into becoming an Active Effect. by @jpmeehan5
• [BREAKING] Changed the properties of additional actions to reflect their more universal nature, see the list below. A migration and data shims have been provided. (#837) by @florad92 rof -> dice shotsUsed - resourcesUsed skillMod and dmgMod have been combined into modifier skillOverride and dmgOverride have been combined into override

-[BREAKING] Changed the property name of the default trait of an item from skill to trait. This means system.actions.skill has now become system.actions.trait. A migration and data shims have been provided. (#837) by @florad92

• Added the new action type macro which allows users to save the UUID of a Macro to then later execute it. The triggering item is available in the Macro context under the item variable. Please keep in mind that normal permission limitations for Macros still apply! (#684) by @florad92
• Improved handling of off-hand weapons and added support for Ambidextrous edge via flags.swade.ambidextrous??
• Added support for ignoring wounds from a second Shaken result via flags.swade.hardy and bleeding out from a failed vigor roll upon incapacitation via flags.swade.ignoreBleedOut

Close to complete, I'll move the macro thing to another issues as it is just not supported, not breaking nothing.
