:version:`3.1.3 <v3.1.2...v3.1.3>` - 2021-03-08
-----------------------------------------------
**Added**
- ``count_operations`` boolean flag to ``runner.prepare``. In case of ``False`` value, Schemathesis won't count the total number of operations upfront.
It improves performance for the direct ``runner`` usage, especially on large schemas.
Schemathesis CLI will still use these calculations to display the progress during execution, but this behavior may become configurable in the future.
