Did I miss something?
mempool.space shows transactions with the fee as low as 0.1 sat/vB in candidate blocks.
f3666861f6f498a7b2075b4129f7c3e9623caa2aa94f4b4992c30090e1a84c61 is one of them with fee 0.41 sat/vB.
Did miners change their policy regarding the minimum feerate they accept for transactions to be included in the mempool?
