<p>
Creates a <a
href="https://docs.aws.amazon.com/step-functions/latest/dg/concepts-state-machine-version.html">version</a> from
the current revision of a state machine. Use versions to create immutable snapshots of your state machine. You
can start executions from versions either directly or with an alias. To create an alias, use
<a>CreateStateMachineAlias</a>.
</p>
<p>
You can publish up to 1000 versions for each state machine. You must manually delete unused versions using the
<a>DeleteStateMachineVersion</a> API action.
</p>
<p>
<code>PublishStateMachineVersion</code> is an idempotent API. It doesn't create a duplicate state machine version
if it already exists for the current revision. Step Functions bases <code>PublishStateMachineVersion</code>'s
idempotency check on the <code>stateMachineArn</code>, <code>name</code>, and <code>revisionId</code> parameters.
Requests with the same parameters return a successful idempotent response. If you don't specify a
<code>revisionId</code>, Step Functions checks for a previously published version of the state machine's current
revision.
