On the JS/TS client side: **Taquito v25.0.0** is out with U025 support; the `PsUshuai9…` protocol hash registered, U025 as the default for local forging and Michelson encoding, the new U025 RPC constants fields (DAL params, stake-cache cycles, canonical smart-rollup address), and `USHUAIANET` wired through the network mapping. dApp and SDK developers can pull it from npm now.

Details and upgrade notes: [Taquito v25.0.0: Ushuaia (U025) protocol support](https://forum.tezosagora.org/t/taquito-v25-0-0-ushuaia-u025-protocol-support/7123)
