+#### Package API
+
+Unlike our CLI tool,
+[Task's package API is not currently stable](https://taskfile.dev/reference/package).
+In an effort to ease the pain of breaking changes for our users, we will be
+providing changelogs for our package API going forwards. The hope is that these
+changes will provide a better long-term experience for our users and allow to
+stabilize the API in the future. #121 now tracks this piece of work.

+  - No longer accepts an `io.Writer` (output is now the caller's

+  - The function now returns the full path of the generated file.

 ## v3.41.0 - 2025-01-18
