v0.3.0-beta

This is a hardfork release for Amoy testnet, scheduled for August 28th 2025, at around 08:00 UTC (block number 13143851)

It mainly contains the following changes.

Breaking changes:

• a permanent fix for the recent outage requiring a hardfork, hence all nodes operators are required to upgrade ahead of time.
• the deletion of bridge as standalone process. This means the bridge can't run now as a separate process, but will always be embedded in heimdalld as a child process via the --bridge flag. All validators (hence running the bridge) will need to adapt and use heimdalld start --bridge --all --rest-server (or variants of this commands based on their setup) to start the bridge within heimdalld service.

New features, improvements and bug fixes:

• Improvements to the bridge service and rest-server connection
• Validation of bor_chain_id during checkpoints workflow at side_server level against the chain parameters
• bump of dependencies
• replace nhooyr.io library with github.com/coder ws as per #421 (thanks @DaveWK for your contribution)
• Fix some functions' comments as per #383 (thanks @stellrust for your contribution)
• Expose proposer transfer event during EndBlocker as per #376 (thanks @haiyanghe for your contribution).
• Replace matic-cli with kurtosis for CI e2e tests
• additional metrics for side_msgs and ABCI handlers
• Removal of spans backfill logic post v1->v2 migration
• Fix the generate-keystore command
• Various minor improvements
