InfluxDB has introduced changes in its syntax, specifically regarding field keys and tag keys, where the `::` syntax can be used to specify if an identifier is a field or tag, allowing users to query both fields and tags with unique names. Additionally, InfluxDB version 1.2.4 has changed the behavior of writes with `time` as a field key or tag key, rejecting such writes and returning errors. Chronograf now supports existing Kapacitor tasks, but with limited functionality in its user interface, requiring manual editing of TICKscripts outside of the interface.
