Release Notes

serilog/serilog

v2.12.0

Highlights of 2.12.0

Improved and expanded <Nullable>enable</Nullable> support

A huge number of commits have gone into completing and refining non-null reference type annotations, which now cover the entire public Serilog API. The Serilog project itself now builds with non-null reference type checking globally enabled 🎉

IAsyncDisposable support

Sinks that need to flush changes using asynchronous APIs can now implement IAsyncDisposable and prevent the possibility of deadlocking while waiting for tasks to complete.

To drive this, Logger can now be disposed via using async:

await using var log = new LoggerConfiguration().CreateLogger();

and the Log class provides Log.CloseAndFlushAsync():

await Log.CloseAndFlushAsync();

DateOnly and TimeOnly support

The DateOnly and TimeOnly types introduced in .NET 6 are now correctly handled as scalar values when capturing.
