v3.0.0

Added

• Support for the Allegra era on the chain-sync, tx submission and state query protocols.
• Support for the Mary era on the chain-sync, tx submission and state query protocols.
• Support for multi-era state queries, or said differently, Ogmios can survive a hard-fork without being restarted or re-compiled.
• Allow clients to also make state queries based on the node's tip (instead of passing an explicit point to acquire).
• Interactive dashboard leveraging Ogmios health's endpoint and local state query protocol to show metrics in real-time.
• Automated smoke sanity tests executed on a running instance, running queries and chain-syncs across all eras.
• Various internal optimization, in particular with rewards to the chain-sync protocol (~14.000 blocks/s in Byron, ~2500 block/s in Shelley and beyond).
• Additional metrics for monitoring: current heap size, total messages, total unrouted messages and start time.
• Configurable HTTP server timeout from the command-line, with sensible defaults.

Changed

• Improve error responses to invalid clients' requests (instead of generic error messages).
• Fixed various typos and clumsy wording in the user manual.
• Reworked internal architecture as a Three-Layer Haskell Cake.
• Changed internal dependencies for base16 and base64 encoding for better performances.
• Upgraded internal dependencies to the Cardano eco-system working with [email protected]
• Improved error handling of the Ogmios server, in particular in case of connections lost with the underlying node.
• The server now returns an explicit client error when interleaving 'FindIntersect' messages in-between pipelined 'RequestNext'.
• Revised default compilation flags .
