The team is very excited to have relased the work on reducing the memory footprint of the Hydra node by merging #1618. This has been tested and appears to make a huge impact to long-running Hydra nodes with many transactions. We invite the community to test it more! We also made a couple of hotfixes and documentation improvements.

This week, the Mithril team continued working on the aggregator's prototype 'slave' mode to support signer registration across multiple aggregators. This feature is being stabilized and tested. They also focused on implementing incremental certification of the Cardano database, emphasizing feature stabilization, production readiness, testing, and optimization. Additionally, the team started refactoring the cryptographic library to improve clarity and maintainability and kept working on signing ancillary files in the Cardano database snapshots with an IOG key.
Finally, the team enhanced the database tooling for migration and maintenance and fixed some flakiness in the CI.

We merged ouroboros-network#5018 which adds support for SRV in ouroboros-network.
However, we still need to make a decision whether we require that all Cardano
SRVs start with _cardano._tcp, or we leave it open for the future. The
former would allow us to use SRVs for different applications, e.g.
_mithril._tcp for the mithril diffusion. If that would be the case then we'd
prepend _cardano._tcp to what we find in the SRV field of a registration
certificate, e.g. prepend _cardano._tcp by cardano-node's diffusion, and
_mithril._tcp by the mithril diffusion. The other possibility is to extend
the registration certificate to include the addresses of mithril nodes.
We started working on a development plan for Mithril diffusion, [ref][mithirl-diffusion] (note that this is a work in progress).
We also have been working on moving network-related code from the
cardano-node to the cardano-diffusion library in ouroboros-network. In the
future, this will allow us to share parts of it in the Mithril diffusion [ouroboros-newtork#5082].
We improved our CDDL specifications by annotating which codecs require definite / in-definite encoding of lists & maps, see ouroboros-network#5089.
Karl Knutsson (CF) has been working on performance improvements in the
multiplexer (network-mux library), ouroboros-network#5093.
Karl Kntusson (CF) noticed a performance bottleneck in the responder (server) side of the p2p diffusion layer. We've started working on addressing this issue.
We continued reviewing/improving the tx-submission PR ouroboros-network#4887.
