For context, Bountysource is a site that lets people put bounties on feature requests for open-source software. A developer who implements the request can then claim the bounty.

Anyway, this change adds a "bounty time-out", so after 2 years, bounties go away and Bountysource keeps all the money. Worse, this change is retroactive: it doesn't just apply to new bounties, but to any posted since June 30, 2018.
