 - `Propulsion` [![NuGet](https://img.shields.io/nuget/v/Propulsion.svg)](https://www.nuget.org/packages/Propulsion/) Implements core functionality in a channel-independent fashion including `ParallelProjector`, `StreamsProjector`. [Depends](https://www.fuget.org/packages/Propulsion) on `MathNet.Numerics`, `Serilog`
 - `Propulsion.Cosmos` [![NuGet](https://img.shields.io/nuget/v/Propulsion.Cosmos.svg)](https://www.nuget.org/packages/Propulsion.Cosmos/) Provides bindings to Azure CosmosDb a) writing to `Equinox.Cosmos` :- `CosmosSink` b) reading from CosmosDb's changefeed by wrapping the [`dotnet-changefeedprocessor` library](https://github.com/Azure/azure-documentdb-changefeedprocessor-dotnet) :- `CosmosSource`. [Depends](https://www.fuget.org/packages/Propulsion.Cosmos) on `Equinox.Cosmos`, `Microsoft.Azure.DocumentDB.ChangeFeedProcessor`, `Serilog`
 - `Propulsion.EventStore` [![NuGet](https://img.shields.io/nuget/v/Propulsion.EventStore.svg)](https://www.nuget.org/packages/Propulsion.EventStore/).

-- `Propulsion.Kafka` [![NuGet](https://img.shields.io/nuget/v/Propulsion.Kafka.svg)](https://www.nuget.org/packages/Propulsion.Kafka/) Provides bindings for producing and consuming both streamwise and in parallel. Includes a standard codec for use with streamwise projection and consumption, `Propulsion.Kafka.Codec.NewtonsoftJson.RenderedSpan`. [Depends](https://www.fuget.org/packages/Propulsion.Kafka) on `FsKafka` v ` = 1.4.2`, `Serilog`
-- `Propulsion.Kafka0` [![NuGet](https://img.shields.io/nuget/v/Propulsion.Kafka0.svg)](https://www.nuget.org/packages/Propulsion.Kafka0/). Same functionality/purpose as `Propulsion.Kafka` but uses `FsKafka0` instead of `FsKafka` in order to target an older `Confluent.Kafka`/`librdkafka` version pairing for interoperability with systems that have a hard dependency on that. [Depends](https://www.fuget.org/packages/Propulsion.Kafka0) on `FsKafka0` v `1.4.2` (which depends on Confluent.Kafka [0.11.3]`, `librdkafka.redist [0.11.4]`), `Serilog`

 The ubiquitous `Serilog` dependency is solely on the core module, not any sinks, i.e. you configure to emit to `NLog` etc.
