 # CHANGELOG
 
+## 2024-xx-xx - Tiny Cloud v3.1.0
+
+* Default to "/usr merge" friendly installation locations
+
+* Configure cloud provider via kernel cmdline or DMI system serial -- either
+  with `ds=<cloud>` or `tinycloud=cloud=<cloud>` (we may introduce additional
+  cmdline Tiny Cloud config settings in the future).
+
+* Autodetection of `aws`, `azure`, `gcp`, and `oci` cloud providers via DMI
+  information.
+
+* Make sure all user-data handlers get installed.
+
 ## 2024-11-04 - Tiny Cloud v3.0.8
 
 * Officially add Makefile targets and flesh out tests for newer cloud modules:
