http://lambda.{region}.amazonaws.com/2015-03-31/functions/{FunctionName}/versions<p>Creates a <a href="https://docs.aws.amazon.com/lambda/latest/dg/versioning-aliases.html">version</a> from the current code and configuration of a function. Use versions to create a snapshot of your function code and configuration that doesn't change.</p> <p>Lambda doesn't publish a version if the function's configuration and code haven't changed since the last version. Use <a>UpdateFunctionCode</a> or <a>UpdateFunctionConfiguration</a> to update the function before publishing a version.</p> <p>Clients can invoke versions directly or with an alias. To create an alias, use <a>CreateAlias</a>.</p>

Only publish a version if the hash value matches the value that's specified. Use this option to avoid publishing a version if the function code has changed since you last updated it. You can get the hash for the version that you uploaded from the output of <a>UpdateFunctionCode</a>.
Only update the function if the revision ID matches the ID that's specified. Use this option to avoid publishing a version if the function configuration has changed since you last updated it.
A description for the version to override the description in the function configuration.
