v0.6.12

This release focuses on Uptime Tracking and Etna compatibility.

Compatibility

The plugin version is changed at 38 and is compatible with AvalancheGo versions v1.11.13 and v1.12.0-fuji.

This version (v0.6.12) can be used for both new AvalancheGo v1.11.13 release and v1.12.0-fuji Pre-release. Backward compatibility changes based on the AvalancheGo version accompanying this version.

For AvalancheGo-v1.11.x versions, Subnet-EVM v0.6.12 is backwards compatible to v0.6.0 and it is optional.

For AvalancheGo-v1.12.x (including v1.12.0-fuji), Etna activation introduces non-backward compatible changes.

Updates

• Refactored the warp backend and implemented the ACP-118 handler to increase the compatibility with relayers and VMs
• Added acceptedBlockDB, metadataDB, warpDB, validatorsDB inspections for inspect-database flag
• Added Uptime Tracking to Subnet-EVM that can track Subnet/L1 validators and their uptimes
• Added new ValidatorUptime warp message type and verification to verify and sign requested validator uptimes

APIs

• Added new validators handler (ext/bc/<blockchainID>/validators) and validators.getCurrentValidators API method

Configs

• Added validators-api-enabled to chain config for enabling/disabling the Validators API handler. Default is true

Fixes

• Fixed the VersionDB for MetadataDB and AcceptedBlockDB (PR #1375)
• Removed the unused shared memory and fixed persisting the VersionDB for Standalone DBs (PR #1383)
