2013: the Season 3 baseline
League of Legends Season 3 is remembered as a distinct period of champion availability, itemization, map systems, professional play, and client behavior. Season 3 is a useful historical label, but it is not one immutable patch. Any precise roster, recipe, price, or statistic needs a version identifier.
Late Season 3: Data Dragon 3.15.5

During the July 2026 research window, Google Trends surfaced League Classic under Games, while Similarweb reported strong recent growth for the main query and roster variant. That demand makes a focused reference useful, but it does not settle release details or rules.
What will move from pending to confirmed
The tracker will be updated when an accessible Riot-controlled source establishes release timing, client access, eligible regions, roster, patch basis, map, queue type, progression, or economy. Each confirmation needs a source URL and review date.
Timeline principle: a spike tells us what people need explained; an official source tells us what we can state as fact.
