Aptos Labs has rolled out the v1.48.1-rc release for its testnet node, marking the latest iteration of the core protocol. The update is available on GitHub and is intended for developers who wish to experiment with the new features before they are promoted to mainnet.
One of the primary changes is the bump of the gas schedule to version 48. This adjustment aligns the testnet with the upcoming mainnet schedule and introduces new gas cost parameters for certain transaction types.
The release also contains several refactoring efforts. The mono-move module now has a simplified function display, and typed errors have been added to the loader to improve debugging. Additionally, the forge deployer version has been updated to ensure compatibility with the new gas schedule.
A change to the BlockMetadata benchmark was made to better reflect performance metrics under the updated gas schedule. These adjustments help developers measure node throughput more accurately during testing.
Developers can clone the repository, build the node, and run it against the testnet. Aptos Labs encourages community feedback on the release, noting that the rc tag indicates a release candidate that may still undergo further refinement.
