.. only:: asciidoc Backwards Compatibility ======================= This specification supports backwards compatibility by use of the `manifest_version <#manifest-version>`_ property. This specification corresponds to version ``2`` as the value for that field. Implementations =============== This submission aims to coincide with development efforts towards widespread implementation in commonly-used development tools. The following tools are known to have begun or are nearing completion of a supporting implementation. - `Truffle `_ - `Populus `_ - `Embark `_ Full support in implementation **may** require `Further Work`_, specified below. Further Work ============ This EIP addresses only the data format for package descriptions. Excluded from the scope of this specification are: - Package registry interface definition - Tooling integration, or how packages are stored on disk. These efforts **should** be considered separate, warranting future dependent EIP submssions. Acknowledgements ================ The authors of this document would like to thank the original authors of `EIP-190 `_, `ETHPrize `_ for their funding support, all community `contributors `_, and the Ethereum community at large.
