## Notable Changes

* [CONJS-288](https://jira.mariadb.org/browse/CONJS-288) A pool timeout error now returns connection timeout details

## Issues Fixed

* [CONJS-289](https://jira.mariadb.org/browse/CONJS-289) Connection can possibly stay in hang state after batch execution
  * [CONJS-290](https://jira.mariadb.org/browse/CONJS-290) When using batch with big values, a connection might be in a wrong state, which can result in Server error: `'(Got an error reading communication packets)'`
  * Client TCP error `ECONRESET`
* [CONJS-292](https://jira.mariadb.org/browse/CONJS-292) Connector does not permit passing a String object (≠ native string) parameter
  * `const objVal = new String('myValue');`
* [CONJS-286](https://jira.mariadb.org/browse/CONJS-286) When using a prepared statement and explicitly disabling prepare cache using prepareCacheLength=0, the connector might not retrieve results anymore
* [CONJS-287](https://jira.mariadb.org/browse/CONJS-287) Typescript is missing `'QueryOption'` for the `'prepare'` command
* [CONJS-293](https://jira.mariadb.org/browse/CONJS-293) When using batch, javascript Date values that are not in the range `1970-01-01 00:00:01 - 2038-01-19 03:14:07` are saved as null
