Zcash Shielded Assets, the first time round.
Released 2 June 2026 as 6.16.0, last patch 6.16.6 on 6 June 2026.
Shielded assets
On the ZSA testnet, Zkool shows the assets an account holds, issues new assets, and sends them: the send page has a currency selector with ZEC and the assets you hold. The history and the transaction details show the asset and its amount, with the amount of the asset as the main figure of an asset-only transfer and the asset's name where it is known. Asset names can be edited in place. See Using ZSA with Zkool.
The patch releases fixed the ZEC balance and the note selection, which had counted asset notes as ZEC, and the fee of an issuance.
Removed
The coin voting feature of 6.11 is removed. Voting came back in 6.27 on a new design.
