Today, I sent a Bitcoin payment but it has not been included in a block for about 10 hours now. The payment had the following characteristics:
- ~0.1 BTC
- 222 bytes
- One UTXO as an input (I used coin control)
- The UTXO was approximately 1 year old
Currently, blocks are not always full (in fact there are blocks that are only 8% full). For that reason I attempted to save the fee.

What policy do miners currently have regarding zero fee transactions? I have sent many zero fee transactions in the past (>1 year ago) and the block inclusion time was really quick (~5 blocks maybe). Did the policy of miners change?
