> Specify regex for Remapping extraction rules, and a bunch of improvements in Logs Explorer.

Source: https://last9.io/changelog/improvements-to-remapping-and-logs-explorer/

### Improvements

- Support for specifying a regex pattern while defining a new extraction rule in [Remapping](https://app.last9.io/control-plane/remapping).
- See the total number of log lines in a query result in [Logs Explorer](https://app.last9.io/logs).
- If the log body has a JSON, it’s prettified when you’ve enabled `wrap lines` in the table view.
- Prettified JSON is now the default view when you open the Log Details sidepanel.
- We’ll remember if you’d enabled `wrap lines` the last time.
- You can now download up to 20,000 log lines as CSV from the query results.
