 ## [Unreleased]
+### Added
+- Add `snafu` as dependency. `snafu` provide macros for creating domain specific errors and adding
+  context to the underlying source errors.
+
 ### Changed
 - Change the public API of `ApplyTcpOptionsError`. So this is a breaking change. This stops
   exposing the internal details of the type which allows future changes to not be breaking.
 - MSRV bumps to 1.85
 - Rust language edition upgraded to 2024.
 
+### Removed
+- Remove dependency `err-context`.
