 - `grafana` has been updated to version 11.1. This version doesn't support setting `http_addr` to a hostname anymore, an IP address is expected.
 
-- `deno` has been updated to v2 which has breaking changes. Upstream will be abandoning v1 soon but for now you can use `deno_1` if you are yet to migrate (will be removed prior to cutting a final 24.11 release).
+- `deno` has been updated to Deno 2, which has breaking changes.

-      Deno aims to be a productive and secure scripting environment for the modern programmer.
-      Deno will always be distributed as a single executable.
-      Given a URL to a Deno program, it is runnable with nothing more than the ~15 megabyte zipped executable.
-      Deno explicitly takes on the role of both runtime and package manager.
-      It uses a standard browser-compatible protocol for loading modules: URLs.
-      Among other things, Deno is a great replacement for utility scripts that may have been historically written with
