Changelog

Release date	Update	Changes
August 19, 2026	v2026.08.19	DX Coolant is available for 250 Salvage each. There’s a daily purchase limit that grows with your total module levels (capped at 5,000 per day).
June 9, 2026	v2026.06.09	The heat tooltip now lists DX Coolant and overclock drift as their own lines for better transparency.
June 4, 2026	v2026.06.04	Relay bay cards now show clear timing and state info: remaining overclock time, cooldown end, and how long active DX Coolant will last on that bay. DX Coolant can be active per bay (you can run coolant on mint and refinery at the same time), and the heat readout is now next to the bay name consistently on desktop and mobile.
May 23, 2026	v2026.05.23	You can now apply DX Coolant to a bay that is in forced recovery to shave time off its recovery pool.
May 21, 2026	Welcome to the Relay Network	Heat is the new throttle. Bays generate heat while they run. You manage it with bay modes and DX Coolant. Items are grouped into four categories: Raw, Crafted, Gear, and Consumable. Some items are explicitly excluded from refine list (boosts, bounties, DX Coolant, rare loot). Daily Refined: the top 10 split a DX Coolant ladder (1 up to 10 coolants, 55 total) plus a 666-Salvage lottery. DX Coolant drops at every quest level 25, scaling from 1 up to 10 per claim.

December 5, 2024	The Quests Update: A Cold Start	DX Coolant is introduced as a seasonal Item, initially without an active use.
