<p>As you can see, only 10.8% of nodes have upgraded to 0.11 and 29.3% of nodes use a pre-0.10 distribution. (Source: <a href="https://getaddr.bitnodes.io/dashboard/#user-agents" rel="nofollow noreferrer">https://getaddr.bitnodes.io/dashboard/#user-agents</a>)</p>

<p>Considering that we don't know the hashing power of these nodes and don't know your definition of "swiftly included", there's no way to exactly answer your query.</p>

<p>However, if you assume hashing power to be equally distributed between nodes, There's about a 10% chance that any give block will be mined by someone running 0.11, so about a 47% chance that a 0.11 block will be mined at least once an hour.</p>

Keep in mind that this is a relay rule. It affects how the transactions make their way around the network as well.

<p>I remember having the same question when the initial OP_RETURN ability came out in Bitcoin Core 0.9, but most of the network was still running 0.8.</p>

<p>I remember that it began to be reliable to send OP_RETURN transactions and get them mined once around 30% of the network was willing to relay them.</p>

<p>So you should keep an eye on <a href="https://getaddr.bitnodes.io/dashboard/#user-agents" rel="nofollow">https://getaddr.bitnodes.io/dashboard/#user-agents</a> for a similar %age.</p>

<p>I heard bitcoin-core 0.11 allows 80 byte OP_Returns, but I know miners operate different implementations and was wondering when it would be likely that 80 byte OP_Returns will be swiftly included in blocks.</p>

When can I send 80 byte OP_Returns?
