Changelog

This is a development pre-release.

Supported polkadot-sdk rev: 2503.0.1

Changed

• Removed the license printer from the resolc binary.
• EVM bytecode is no longer requested from solc (except in test utils) leading to less compilation work in the pipeline.

Fixed

• solc-json-interface: Serializing of any custom key in the JSON input is only skipped if not provided.
• npm package resolution no longer fails with an 'ERR_PACKAGE_PATH_NOT_EXPORTED' error for packages defining exports fields in the package.json.

Note for macOS Users

v0.1.0

Changelog

This is a development pre-release.

Supported polkadot-sdk rev: 2503.0.1

Added

• Add the PolkaVM heap size, stack size and debug info CLI compiler options to the standard JSON settings. This makes the standard JSON input succint for reproducible builds.

Changed

• Supported polkadot-sdk version is now 2503.0.1
• The emsdk version is now 4.0.9

v0.1.0-dev.16

Changelog

This is a development pre-release.

Supported polkadot-sdk rev:c29e72a8628835e34deb6aa7db9a78a2e4eabcee

Added

• Move the npm package from paritytech/js-revive, into this repo. The package @parity/resolc will be deployed to npm for each release.
• Support for solc v0.8.30

Changed

• By default, heavy size optimizations are applied.

Fixed

• @parity/resolc: The solc dependency package is constrained to the latest supported version, preventing breaking the package ever time a new solc package was released.
• The resolc npm package no longer ignores the optimizer settings
