In the latest release of InfluxDB, version 1.1, several new features have been introduced to improve performance, stability, and query capabilities. The database now supports mixed duration units in retention policies, continuous queries, and time conditions, allowing for more flexibility when specifying durations. Additionally, a configuration setting called `max-values-per-tag` has been added to limit series cardinality, preventing excessive tag values from being written. Furthermore, InfluxQL support for linear interpolation in GROUP BY time() queries has been enhanced, enabling users to specify the interpolation method for filling gaps in data without any data points. These updates aim to make working with InfluxDB more efficient and user-friendly.
