Exciting news this week! The Zcash Sapling network upgrade activated at block height 419200. Sapling introduces new shielded addresses with significantly improved performance: a time reduction of 90% for constructing transactions, and a memory reduction of over 97%. More details are available here.
Sapling received lots of great press; here are just a few among the many:

Happy Birthday Zcash! Sapling activation coincided with the two-year birthday of Zcash. This brings us one step closer to widespread adoption of an open, permissionless and private payment system.
On October 30, the Zcash Foundation and Parity Technologies announced a technical partnership to build a consensus-compatible Zcash node. Parity plans to devote significant development resources to the project, using Parity Bitcoin as a starting point and writing in the Rust programming language. The Zcash Foundation will contribute its own engineers as the organization’s hiring and community funding processes allow.
