High level overview​

The Mithril team released the new distribution 2450.0, which offers stable support for Cardano node v.10.1.3 and includes bug fixes and performance improvements.

The team also continued implementing the incremental certification of the Cardano database: they kept working on creating and synchronizing the artifacts, implemented the artifact routes, and started working on the digest route for the incremental Cardano database in the aggregator REST API.

Finally, they completed the experimental cache for certificate verification in the WASM client, implemented enhancements to the CI, and fixed a bug with identifier collisions in the incremental Cardano database artifacts.
