Full Changelog: v0.12.1...v0.12.2

v0.12.1

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.
• P2P Public Address Support: Implemented support for nodes to gossip their public IP address using the p2p-public-addr flag, enabling P2P communication over public networks. (#2011)
• New Execution Step Count Header: Added the X-Cairo-Steps header to track execution steps, providing better monitoring and debugging capabilities. (#1989)

Changed

• Makefile Update for Parallel Build Process: Updated the Makefile to parallelize the build process using all available CPU cores, resulting in faster builds.
• DB Command Replacement: Introduced a new db command (juno db) for database-related operations, replacing the previous approach. It includes subcommands like:
  • juno db info: Displays blockchain information stored in the database.
  • juno db size: Shows storage information for each bucket in the database.

Fixed

• Conformity with Specification 0.7.1: Fixed the missing execution_resources.data_availability field in starknet_getTransactionReceipt responses, ensuring compliance with spec 0.7.1. (#2078)
