# 0.18.5

## Performance Improvements 🚀

* Introduced two new settings, `paradedb.topn_retry_scale_factor` and `paradedb.max_topn_chunk_size`, which can be used to reduce the number of re-queries during a TopN
  when the index has lots of dead entries

## Stability Improvements 💪

* We now allow text key fields to use the `keyword` tokenizer
* Fixed an index corruption issue related to the free space map
