When we first began writing roadmaps for the in-toto project, the reference implementation was still maturing, and we found it valuable to plan and record its progress independently of the in-toto specification. Today, the reference implementation has reached stability, and closely matches the current version of the specification. As a result, our plans for the future of in-toto no longer affect the implementation or specification alone, but the full project as a whole. Therefore, starting with the 2022 period, please refer to the organization's roadmap for progress reports of the implementation.
