These last 2 weeks were mainly spent at the Dev Summit in Rome, as well as participating in conferences in the area. These include zkSummit, zkProofs, and EuroCrypt.

At the moment, we have two pieces of engineering work in progress: [write performance improvements](https://github.com/ZcashFoundation/zebra/pull/10447) for Zebra’s state layer, and an experimental [implementation of a draft ZIP for shorter block target spacing](https://github.com/ZcashFoundation/zebra/pull/10512).

The platform team has been working on supporting the z.cash domain migration and ownership transition.

Thank you to [@evan-forbes](https://github.com/evan-forbes) for [adding a startup warning to Zebra](https://github.com/ZcashFoundation/zebra/pull/10513) when it detects that the Linux TCP slow-start-after-idle setting is enabled. With this change, operators running Zebra on Linux are told at startup if the setting is active.
