 ### Changed
 - ⚠️ **Breaking**: Module path renamed from `github.com/eshaffer321/monarchmoney-go` to
-  `github.com/eshaffer321/monarch-go`, matching Monarch's rebrand from "Monarch Money" to
-  "Monarch." Consumers must update their import paths and `go get` command:
-  `go get github.com/eshaffer321/monarch-go`.
+  `github.com/eshaffer321/monarch-go/v2`, matching Monarch's rebrand from "Monarch Money" to
+  "Monarch" (the `/v2` suffix is required by Go's module versioning rules for a v2+ release).
+  Consumers must update their import paths and `go get` command:
+  `go get github.com/eshaffer321/monarch-go/v2`.
 - Rebranded docs, comments, and the client `UserAgent` string (now `monarch-go/2.0.0`) from
   "Monarch Money" to "Monarch."

 Go modules use git tags for versioning. When someone runs:
 ```bash
-go get github.com/eshaffer321/monarch-go@v1.2.0

 Go fetches the code at that exact tag. **Without a tag, users cannot access your changes.**
