 ## :bell: Changelog
 
+- **v0.6.2**: Style and colour changes, prometheus hotfix, new options:
+    - `-u`, Allow auto self update of dockcheck.sh
+    - `-I`, Print container release URLs in the CLI "choose update" list. (please contribute to `urls.list`)
+    - Extras: `-m`, Monochrome mode now hides the progress bar.
+- **v0.6.1**: Hotfixes: (try removing set+shopt+shopt if debugging more errors)
+    - xargs/pipefail, removed `-set -e` bash option for now.
+    - unbound variables fixed (hopefully)
+    - dependency installer from pkgmanager rewritten
 - **v0.6.0**: Refactored a lot of code, cleaner logic and syntax, safer variables.
     - Safer bash options with `set -euo pipefail`, `shopt -s nullglob` and `failglob`.
     - Added a `default.conf` for user settings - persistent through updates.
     - Added `notify_slack.sh` template for slack curl api.
-- **v0.5.8**: Added version checks to all templates and a notification if a new template is released.
+
-- **v0.5.7**: Rewritten templates - now with a function to notify when there's a new Dockcheck release.
-    - Manually migrate your current `notify.sh` settings to a new template for new functionality.
-- **v0.5.6.1**: Async xargs hotfix - due to errors `failed to request manifest head ... context canceled`
-    - Defaulted subprocess to 1 with `MaxAsync=1`, increase to find a stable value in your environment.
-    - Added `-x N` option to pass `MaxAsync` value at runtime.
-    - To disable xargs `-P` flag (max processes) all together, set `MaxAsync` to 0.
-- **v0.5.6.0**: Heavily improved performance due to async checking for updates.
