 This log covers the major changes of Wasteland Conquest (index.html).
 
+## v2.4 [Arsenal & Intelligence Update]
+
+* **Companion System:** Added a rare, multi-stage quest to find and rescue Dogmeat. Players can choose to take him in an 'Injured' state (which incurs debuffs) or heal him with resources to unlock powerful combat, loot-nding, and mine-defusing buffs.
+* **Scorched Earth Overhaul:** Ground Zero is no longer permanently destroyed. Nuked territories now suffer severe, 10-turn radiation attrition (80% initial losses) that slowly cools off. The launch engine now supports simultaneous nuclear strikes from multiple factions.
+* **V.A.T.S. Intelligence:** The V.A.T.S. tooltip now displays high-visibility warning banners explaining exactly why a tactical action is blocked (e.g., 'OUT OF RANGE', 'TERRITORY FROZEN SOLID'). It also tracks active nuclear impact countdowns.
+* **Relic & Arsenal Polish:** Fat Man and Cryolator strikes are now strictly limited to a range of 3 territories from your borders. Added theme-colored map icons for planted Mines, Frozen zones, Blockades, and active Expeditions.
+* **Progression & Leveling:** The Level-Up system has been refined to prevent offering duplicate non-stackable perks and now clearly labels upgrades for stackable abilities (e.g., Rank 2, Rank 3).
+* **QoL & System Logic:** RadAway now explicitly grants immunity to Nuke Fallout in addition to weather Radstorms, complete with UI and action log feedback. Bobblehead activations are now strictly phase-locked to prevent accidental wasted uses.
+* **Encounter & Map Polish:** Increased the discovery rate of radio transmissions and post-battle expeditions. Cleaned up legacy SVG map text artifacts.
