Highlights

  • Improved execution speed and module loading speed by bumping to WASM Time to version 4.0.

  • Improved developer experience on the CLI by making the <manifest> argument optional.

    The CLI when <manifest> argument is not provided will now look in the current directory for a substreams.yaml file and is going to use it if present. So if you are in your Substreams project and your file is named substreams.yaml, you can simply do substreams pack, substreams protogen, etc.

    Moreover, we added to possibility to pass a directory containing a substreams.yaml directly so substreams pack path/to/project would work as long as path/to/project contains a file named substreams.yaml.

  • Fixed a bug that was preventing production mode to complete properly when using a bounded block range.

  • Improved overall stability of the Substreams engine.

Operators Notes

  • Breaking Config values substreams-stores-save-interval and substreams-output-cache-save-interval have been merged together into substreams-cache-save-interval in the firehose-<chain> repositories. Refer to chain specific firehose-<chain> repository for further details.

Added

  • The <manifest> can point to a directory that contains a substreams.yaml file instead of having to point to the file directly.

  • The <manifest> parameter is now optional in all commands requiring it.

Fixed

  • Fixed production mode not completing when block range was specified

  • Fixed tier1 crashing due to missing context canceled check.

  • Fixed some code paths where locking could have happened due to incorrect checking of context cancellation.

  • Request validation for blockchain's input type is now made only against the requested module it's transitive dependencies.

Updated

  • Updated WASM Time library to 4.0.0 leading to improved execution speed.

Changed

  • Remove distinction between output-save-interval and store-save-interval.

  • substreams init has been moved under substreams alpha init as this is a feature included by mistake in latest release that should not have been displayed in the main list of commands.

  • substreams codegen has been moved under substreams alpha codegen as this is a feature included by mistake in latest release that should not have been displayed in the main list of commands.
