This release introduces key features for improved monitoring and P2P communication, along with bug fixes and updates to maintain compatibility with the latest specifications.

Added

• New /ready/sync Endpoint: Added the /ready/sync endpoint to check readiness and synchronization status. This endpoint returns 200 if the system is synced within the last six blocks and ready; otherwise, it returns 503. For more details, see #2060.
