 This file is used to list changes made in each version of the kosmos_gitea cookbook.
 
+# 0.2.2
+
+- Add `config.yaml` for the gitea actions runner, enabling the built-in cache
+  server (listening on the Docker bridge gateway `172.17.0.1`) and bumping
+  `runner.capacity` to 2 for concurrent job execution. Each runner gets a unique
+  cache port derived from `cache_base_port` (8088) + its index in the runners
+  data bag.
+- Set `container.network` to a user-defined Docker bridge network
+  (`gitea-actions`, subnet `172.20.0.0/16`) so job containers get DNS resolution
+  for service containers (e.g. `redis`) while keeping the cache server reachable
+  at the network gateway `172.20.0.1`.
+- Open the cache port in the firewall for Docker bridge traffic
+  (`172.20.0.0/16`), fixing `Request timeout` errors from `actions/cache`.
+
 # 0.1.0
