+Nothing changes in Dapple itself. This release fixes how it gets built.
+
+## What's changed
+
+- **Builds no longer stall now and then.** Two copies of the image build could start at once for the same change and get in each other's way, which sometimes held up a release for many minutes. Now the second one waits its turn.
+
+## Upgrading
+
+Running Dapple as a Home Assistant app: install the update from Settings → Updates.
+
+With Docker, `docker compose up -d` picks this up if you have `pull_policy: always`. Otherwise run `docker compose pull && docker compose up -d`. Your settings and saved presets carry over. To stay on this release, set the image line to:
+
+```yaml
+    image: afraley/dapple:0.6.2
+```
