Starting 10 April 2023, fees for card processing, disputes, and USD currency payouts will be higher due to increases in network costs (in recent years, major card networks have introduced several new fees and increased existing fees), as well as increases in underlying service costs.

Processing: An extra 0.1-0.5% increase for UK, 0.35% increase for international.
Disputes: £15 fee turns to £20 fee and no refunds regardless of outcome.

And lots of other little changes. Probably different documents available for your local area.
