It’s Autumn over here, and it usually means another release of Watermill! 🍂 It’s hard to believe it’s already been five years since the v1.0 release.
In case you’re new to Watermill, here’s TL;DR.
Watermill is a Go library for building message-driven or event-driven applications the easy way. Think of it like an HTTP router but for messages. It’s a library, not a framework, so you don’t need to change your architecture to use it.
