+The v1 client libraries for InfluxDB were typically developed and maintained by
+community members. They have all now been succeeded by v2 client libraries.
+They are being archived it in favor of the v2 client library. See
+https://github.com/influxdata/influxdb-csharp/issues/100.

+If there are still users of this v1 client library, and they or somebody else
+are willing to keep them updated with security fixes at a minimum please reach
