-## [Unreleased]
+## [0.1.0] - 2024-07-09
 
 ### Added
 
 - Added an additional URL endpoint (`/cloud-init-secure`) which requires JWT authentication for access
+  - At the Docker level, if the `JWKS_URL` env var is set, this server will attempt to load the corresponding JSON Web Key Set at startup.
+    If this succeeds, the secure route will be enabled, with tokens validated against the JWKS keyset.
+- During a query, if no xnames are found for the given input name (usually a MAC address), the input name is used directly.
+  This enables users to query an xname (i.e. without needing to look up its MAC first and query using that), or a group name.
 
 ### Changed
 
 - Switched from [Gin](https://github.com/gin-gonic/gin) HTTP router to [Chi](https://github.com/go-chi/chi)
+- When adding entries to the internal datastore, names are no longer "slug-ified" (via the `gosimple/slug` package).
+  This means that when a user requests data for a node, the name they query should be a standard colon-separated MAC address, as opposed to using dashes.
