### Resource limits
`render_score_limit` and `cumulative_render_score_limit` account for each item visited by
integer-range `for` and `tablerow` loops, including loops with empty bodies. This bounds range
iteration work when a score limit is configured; `render_length_limit` only bounds generated
output and does not by itself limit CPU work for output-free loops.
### Usage tracking
To help track usages of a feature or code path in production, we have released opt-in usage tracking. To enable this, we provide an empty `Liquid:: Usage.increment` method which you can customize to your needs. The feature is well suited to https://github.com/Shopify/statsd-instrument. However, the choice of implementation is up to you.
