Hello! There are a lot of updates this week. Let’s get to it!

Outreach

Status: Resumed
We’ve concluded Zcashd 6.3.0 roll out. We are still monitoring the situation (thanks @edicksonga for some reports). We are now starting a Zcash Network Upgrade Friction Survey to get some insight on pain points generated by transaction changes in the ecosystem. @nuttycom proposed this in Light Client Working Group and we kicked it off right away.

ZF folks released Zebra 2.5.0 which enables NU 6.1 in testnet. Zebra now does Orchard batch validation and also has a few more enhancements to existing RPCs to be more compatible with Block Explorers and Zcashd clients. Also the team keeps housekeeping continuous integration (CI) infrastructure and contributing to the Z3 distribution pipeline.
