ECC timeline updates and planning for 2022
And we’re planning for a big January release of the Halo Arc product suite, including the NU5-compatible Zcashd, an updated ECC Reference Wallet, updated mobile wallet SDKs, and features that will enable Zcash to be Shielded by Default.
New releases to help enable Zcash Shielded by Default
We’re introducing “auto-shielding” in our mobile wallet SDKs and unified addresses at the Zcash protocol level. In supporting wallets, these two features ensure your Zcash transaction and balance information is automatically encrypted — Shielded by Default — in the latest, most secure shielded pool.
New Release 4.4.1
The 4.3.0 release included a change to prevent redundant getheaders P2P requests, to reduce node bandwidth usage. This behaviour could be disabled by setting the config option -nooptimize-getheaders.
New Release 4.4.0
zcashd can now be configured to optionally expose an HTTP server that acts as a Prometheus scrape endpoint. The server will respond to GET requests on any request path.
New Release 4.3.0
The latest release includes traffic improvements, a reworked library and other updates.
