Hello,

It is my great pleasure to announce the release of ERIS v0.4.0:

https://codeberg.org/eris/spec/src/tag/v0.4.0

The rendered version is available at http://purl.org/eris .

This version contains significant changes to the encoding itself and to
the specification document. We hope to have addressed the feedback and
issues brought up towards version 0.3.0 of the specification. In
particular we hope to have addressed the issues raised during the Quick
Security Evaluation by ROS [1].

We intend to stabilize the encoding very soon. Version 0.4.0 is intended
to gather final feedback and comments before releasing 1.0.0.

Changes to the encoding itself include:

- Encode the level of node in the nonce used to encrypt the node [2]
- Use keyed Blake2b only for leaf nodes [3]

This version of the encoding breaks compatibility with previous
versions. To differentiate from content encoded with previous version we
use the namespace identifier `erisx3` in the URN encoding of read
capabilities.

Changes to the specification document include:

- Reformat as IETF RFC XML
- Change pseudocode syntax and make data types more explicit
- Add more diagrams (and redraw existing) to also illustrate edge cases
- Add negative test vectors that should help implementors ensure correct
  verification during decoding.

For a complete list of changes see the Changelog
(https://eris.codeberg.page/spec/#name-changelog).

I'm also very happy to announce that we have received funding from
NLnet/NGI Assure to finalize the encoding, develop implementations and
applications. See also the project plan for details
(https://codeberg.org/eris/meta/src/branch/main/ngi-assure/project-plan.org).

Towards making ERIS practically useful we have started documenting
extensions and recommendations: https://eris.codeberg.page/eer/ . This
includes recommendations on how to use ERIS over HTTP, how to encode RDF
with ERIS or how to create efficient appendable logs. Stay tuned for more!

Best regards,
pukkamustard

I'm impressed at your pragmatism. You can't cease to amaze me. :)
