More detailed description and reasons behind this changes are described here

v7

• Now level label is not created by default

To keep previous behavior set createLevelLabel to true at sink configuration

 .WriteTo.GrafanaLoki(
                    "http://localhost:3100",
                    createLevelLabel: true)

      {
        "Name": "GrafanaLoki",
        "Args": {
          "uri": "http://localhost:3100",
          "createLevelLabel": true
        }
      }

v6

• Deprecated dependency Serilog.Sinks.Http
• Replaced IHttpClient with ILokiHttpClient Migration guide: You will have to migrate your code if you've implemented your own version of ILokiHttpClient. The signature of method ILokiHttpClient.PostAsync (before upgrade IHttpClient.PostAsync has changed from Task PostAsync(string, HttpContent) to Task PostAsync(string, Stream).

Before upgrade:

public class CustomLokiHttpClient : IHttpClient
{
  // Code removed for brevity...

  public async Task<HttpResponseMessage> PostAsync(string requestUri, HttpContent content)
  {
    // Here you probably have some code updating the content,
    // and then you send the request
    return await httpClient.PostAsync(requestUri, content)
  }
}

After update:

public class CustomLokiHttpClient : ILokiHttpClient
{
  // Code removed for brevity...

  public async Task<HttpResponseMessage> PostAsync(string requestUri, Stream contentStream)
  {
      using var content = new StreamContent(contentStream);

      // Here you probably have some code updating the content,
      // and then you send the request
      return await httpClient.PostAsync(requestUri, content)
  }
}

v5

• Removed DurableGrafanaLokiUsingTimeRolledBuffers and DurableGrafanaLokiUsingFileSizeRolledBuffers

v4

• Replaced excludedLabels with filtrationMode and filtrationLabels
