Breaking API Changes** We upgraded all of our samples to use the new `OpenTelemetry.Extensions.Hosting` v1.4.0 API and we recommend that you update to this version. For upgrading from Phobos 1.x to Phobos 2.1.1, follow the instructions in [this upgrade page](https://phobos.petabridge.com/articles/setup/upgrading-phobos-1.0-to-2.0.html) For upgrading from Phobos 2.0 or 2.1 to Phobos 2.1.1 and the new recommended `OpenTelemetry.Extensions.Hosting` API, follow the instruction in [this upgrade page](https://phobos.petabridge.com/articles/setup/upgrading-phobos-2.x-to-2.3.html) Other Changes** Upgraded to [OpenTelemetry v1.6.0](https://github.com/open-telemetry/opentelemetry-dotnet/releases/tag/core-1.6.0) [Upgraded OpenTelemetry.Extensions.Hosting on all samples to 1.6.0](https://github.com/petabridge/phobos/pull/1221) Restored lost functionality from Phobos 1.x - all messages decorated with `INeverTrace` are never traced; messages decorated with `INeverMonitor` are not monitored; and messages decorated with `INeverInstrumented` (implements both of the previous interfaces) are never traced or monitored under any circumstances.
