 ## :bell: Changelog
 
+- **v0.6.7**: Snooze feature, curl, and consolidation
+    - Added snooze feature to delay notifications
+    - Added configurable default curl arguments
+    - Consolidated and standardized notify template update notifications
+    - Added curl error handling
 - **v0.6.6**: Notify_v2 bugfixes
     - Clearer readme and error messages
     - Sourcing templates from either project root or subdirectory

       - Added support for notification management via environment variables.
       - Moved notification secrets to **dockcheck.config**.
     - Added retries to wget/curl to not get empty responses when github is slow.
-- **v0.6.4**: Restructured the update process - first pulls all updates, then recreates all containers.
-    - Added logic to skip update check on non-compose containers (unless `-r` option).
-    - Added option `-F` to revert to `compose up -d <ContainerName>` targeting specific container and not the stack.
-        - Also added corresponding label and config-option.
-    - Added markdown formatting to `notify_ntfy.sh` template.
-- **v0.6.3**: Some fixes and changes:
-    - Stops when a container recreation (compose up -d) fails, also `up`s the whole stack now.
-    - `-M`, Markdown format url-releasenotes in notification (requires template rework, look at gotify!)
-    - Added [addons/DSM/README.md](./addons/DSM/README.md) for more info Synology DSM info.
-    - Permission checks - graceful exit if no docker permissions + checking if root for pkg-manager.

+#### Legacy installation and configuration:
 Use a previous version of a `notify_X.sh` template file (tag v0.6.4 or earlier) from the **notify_templates** directory,
 copy it to `notify.sh` alongside the script, modify it to your needs! (notify.sh is added to .gitignore)
 
+#### Snooze feature:
+**Use case:** You wish to be notified of available updates in a timely manner, but do not require reminders after the initial notification with the same frequency.
+e.g. *Dockcheck is scheduled to run every hour. You will receive an update notification within an hour of availability.*  
+**Snooze enabled:** you will not receive another notification about updates for this container for a configurable period of time.   
+**Snooze disabled:** you will receive additional notifications every hour.
 
-**Current templates:**
+To enable snooze, uncomment the `SNOOZE_SECONDS` variable in your `dockcheck.config` file and set it to the number of seconds you wish to prevent duplicate alerts.
+The true snooze duration will be 60 seconds less than your configure value to account for minor scheduling or script run time issues.
+If an update becomes available for an item that is not snoozed, notifications will be sent and include all available updates for that item's category, even snoozed items.
+`dockcheck.sh` updates, notification template updates, and container updates are considered three separate categories.
