v0.8.3

⚠️ Warning: Version 0.8.x is compatible only up to Starknet v0.12.3. ⚠️

Added

• API Key Support for Feeder/Gateway: Added support for configuring an API key to bypass feeder/gateway throttling. Use the --gw-api-key flag when running Juno to specify the API key. (@omerfirmak in #1579)

• Flag --db-max-handles: We've introduced a new flag, enabling users to adjust the MaxOpenFiles setting in Pebble. This improvement is aimed at enhancing Juno's ability to manage a higher volume of RPC requests efficiently. (@omerfirmak in #1587)

Changed

• Error Metrics: Revised error metrics to only count internal errors as failed requests. This change addresses the issue where request relatd errors were inaccurately classified as failures in metrics, leading to misleading data. Now, only errors that signify server-level issues contribute to the failure rate. (@omerfirmak in #1566)

• Request Logging: Altered the RPC request logging approach to only log failed requests. Previously, logging all RPC requests resulted in excessive data, making it challenging to pinpoint issues. This update streamlines the process, focusing on capturing only those requests that fail, thereby facilitating easier troubleshooting. (@omerfirmak in #1572)

Fixed

• Class Cache Issue: Addressed an issue where the class cache was serving non-declared classes in certain edge cases. (@omerfirmak in #1571)

Full Changelog: v0.8.2...v0.8.3

Full Changelog: v0.8.2...v0.9.0

v0.8.1

This release focuses solely on fixes for the RPC spec, aiming to improve the accuracy of RPC interactions.

Fixed

• Simulate Transaction Error Handling for RPC v0_5: Addressed an issue where the starknet_simulateTransactions method did not return the correct error upon transaction reversion. (@omerfirmak in #1535)
• EstimateFee Error Fix for RPC v0_5: Resolved an issue where starknet_estimateFee returned TxnExecutionErr instead of contract error. (@omerfirmak in [#1539]
• Starknet Spec Version Update for RPC v0_6: Corrected the supported specification version to 0.6.0 in starknet_specVersion. (@wojciechos in #1536)

Full Changelog: v0.8.0...v0.8.1

v0.8.0

This final release of v0.8.0 is fully compatible with upcoming Starknet 0.13.0 and implements the JSON RPC for v0.6.0, ensuring a smooth and efficient experience.

Key Updates

• Support for Starknet 0.13.0: Fully integrated new features and updates compatible with Starknet 0.13.0.
• JSON RPC spec v0.6 Implementation: RPC v0.6 is now available at endpoints /v0_6 and the default /, replacing the previous default of v0.5.
• Removal of RPC /v0_4: Streamlining our service by supporting only the two most recent RPC versions. RPC /v0_4 is no longer supported.
• Enhanced Database Cache Configuration: The db-cache-size flag allows for custom configuration of the pebble db cache size, optimizing performance and resource management.

Full Changelog: v0.7.6-patch1...v0.8.0

v0.8.0-rc2

This version addresses multiple bug fixes in our Starknet JSON-RPC 0.6.0-rc4 implementation.

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.
• JSON RPC spec v0.6 Implementation: Newly added RPC version. v0.6 is now available at endpoints /v0_6 and the default /, replacing the previous default of v0.5.
• Removal of RPC /v0_4: To maintain a streamlined and efficient service, we support only the two most recent RPC versions. With the introduction of RPC v0.6, we are removing support for the older RPC /v0_4.
• Enhanced Database Cache Configuration: Added the capability to configure the pebble db cache size. The new db-cache-size flag determines the amount of memory allocated for caching data. This enhancement boosts performance and scalability, allowing for more efficient resource management.

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).
