v0.8.0-rc1

This release introduces significant updates with support for upcoming Starknet 0.13.0 and implements the JSON RPC for v0.6.0-rc4.

Key Updates

• Support for Starknet 0.13.0: Seamlessly integrated new features and updates compatible with Starknet 0.13.0.

v0.7.6-patch1

Fixes

• Blockifier and Cairo-VM Incompatibility: Resolved a known incompatibility issue between the blockifier and cairo-vm versions greater than 0.8.2.

Details

• Problem: Incompatibility between blockifier and cairo-vm versions greater than 0.8.2, causing excessive memory usage and resulting in Juno process termination.
• Resolution: Downgraded cairo-vm to version 0.8.2. This approach follows the solution implemented by eqlabs/pathfinder (See PR #1437).
• Outcome: Resolved the memory management issue and restored stability to the node.

Full Changelog: v0.7.6...v0.7.6-patch1

v0.7.6

Hotfix for class cache behavior.

Fixed

• Class Cache Issue: Ensure the class cache does not serve classes from the future. This update fixes traces for declare transactions whose class has already been cached (#1454 by @omerfirmak).

Full Changelog: Juno v0.7.5...v0.7.6

v0.7.5

This release brings a major boost in RPC performance, doubling the handling capacity, and includes important bug fixes to enhance overall node stability.

Added

• Increased VM and VM Queue Limits: Upped the default value for max VMs and VM queue, significantly boosting the node's ability to handle concurrent requests. (#1444 by @omerfirmak)
• Sepolia Network Support: Added support for the Sepolia network. (#1443 by @joshklop)
• L1 Height Metric: Added a new metric for L1 blockchain height, providing deeper insights into node state. (#1441 by @joshklop)

Changed

• Standalone Read-Only Contract Functions: Enhanced performance of starknet_call. (#1432 by @omerfirmak)

Fixed

• Missing contract_address in Write API Responses: Resolved an issue where the contract_address was missing in starknet_addDeployAccountTransaction, ensuring complete and accurate transaction data. (#1440 by @omerfirmak)
• ErrKeyNotFound Consistency Across State Implementations: Aligned all State implementations to return ErrKeyNotFound for missing contracts, streamlining error handling. (#1439 by @omerfirmak)
• Corrected Block Hash State Updates: Updated state handling with previous block hashes for more accurate block tracing. (#1438 by @omerfirmak)
• Query Bit Misuse as SKIP_VALIDATE: Fixed an issue where the query bit was accidentally used as SKIP_VALIDATE, ensuring proper transaction validation. (#1436 by @omerfirmak)

Full Changelog: v0.7.4...v0.7.5

v0.7.4

This release focuses on infrastructure scalability through enhanced gRPC integration, allowing for more efficient node deployment strategies.

Added

• RemoteDB over gRPC: Implement the ability for Juno nodes to connect to a primary node's database over gRPC, serving RPC requests without the need for syncing themselves. This feature is enabled through new flag: --remote-db, streamlining scalability and reducing overhead. (@omerfirmak in #1353)

Changed

• Error Logging: Reduced noise in logs by preventing the recording of errors not attributable to Juno's own operations. This ensures a clearer logging experience and easier troubleshooting. (@joshklop in #1406)

Usage

To deploy a syncing node that exposes its database over gRPC:

docker run -d \
  --name juno_grpc \
  --network juno-net \
  -p 6064:6064 \
  -v /root/snapshots/juno_mainnet:/var/lib/juno \
  nethermind/juno:v0.7.4 \
  --db-path /var/lib/juno \
  --grpc-host 0.0.0.0 \
  --grpc-port 6064 \
  --grpc

To deploy a node that uses the primary node’s synced database over gRPC:

docker run -d \
  --name juno_from_grpc \
  --network juno-net \
  -p 6065:6065 \
  nethermind/juno:v0.7.4 \
  --http \
  --http-port 6065 \
  --http-host 0.0.0.0 \
  --remote-db juno_grpc:6064

Here’s what’s new:

Added

• Support for Starknet v0.12.3
• A global class cache to the VM which enhances overall RPC throughput. (PR by @omerfirmak in 1401
• A new flag, max-vms, to control the maximum number of VM instances for concurrent RPC calls, optimizing resource usage (PR by @omerfirmak in #1378).

Changed

• Subscription handling has been moved to the synchronizer for improved efficiency (PR by @joshklop in #1373).
• Ongoing enhancements to the P2P layer, including the implementation of a Receipt Handler and Adapter and a new GetBlockBodies feature (PRs by @IronGauntlets in #1352 and by @kirugan in #1359).
• Prometheus metrics have been expanded to include version information, latency on Transaction.Commit(), and read metrics on blockchain operations (PRs by @omerfirmak in #1394, #1396, and #1395).
