Greptile Summary

This PR adds a new version-specific update task script (util/updates/update-2.9-tasks.sh) that follows the established pattern in the BirdNET-BarChart project's update system. The script implements a semaphore-based idempotency mechanism using a lock file to prevent duplicate execution, which is consistent with other version update scripts in the codebase.

The script serves as a placeholder for version 2.9 updates, performing no actual migration tasks but maintaining the chain integrity by cascading to the previous version's update script (update-2.8-tasks.sh). This cascading pattern ensures that when the main update.sh script determines the current version via git tags and executes the corresponding update task script, all necessary version-specific migrations are applied in sequence.

The update system is designed to handle version-specific database migrations, configuration changes, or other maintenance tasks that need to be performed when upgrading between versions. In this case, version 2.9 requires no specific update actions, so the script simply creates a lock file to mark completion and chains to the previous version to ensure any older update tasks are also executed if needed.

Confidence score: 4/5

• This PR is safe to merge with minimal risk as it follows established patterns and performs no destructive operations
• Score reflects the simple, well-established pattern being followed with proper idempotency controls and no complex logic changes
• No files require special attention as this is a straightforward addition following existing conventions
