v0.20.0

• Enhancements

  • Queries can be sent as Flux language queries to InfluxDB using [query_language: :flux] in the connection or query options

• Soft deprecations (no warnings)

  • The query builder has been removed from documentation and will be eventually removed completely. This will be done because of the current limitations of the builder implementation and the InfluxDB move from InfluxQL to Flux as the query language of choice

• Deprecations

  • Accessing the system environment by configuring {:system, var} or {:system, var, default} will now result in a Logger.info/1 message and will stop working in a future release
  • Implementing use Instream.Writer has been deprecated in favor of the more explicit @behaviour Instream.Writer. Old implementations will trigger a compile time warning until the old macro is removed
  • The already (soft) deprecated time units with plural names (e.g. :seconds) will now issue Logger.info/1 messages when used

• Backwards incompatible changes

  • Support for the InfluxDB versions earlier than 1.4.x is no longer guaranteed
