-- Updated zebrad's mempool transaction downloader for zebra-consensus's transaction-verifier API
-  split: the removed `transaction::Request::Mempool`/`transaction::Response::Mempool` enum
-  variants are replaced by dedicated `transaction::MempoolRequest`/`transaction::MempoolResponse`
-  types. Internal-only; no user-facing or operator-facing behavior change. See zebra-consensus's
-  changelog for the underlying API split

-- New `getdeprecationinfo` RPC returning the block height and estimated time at which this
-  release will halt for end of support, in zcashd's `end_of_service` format. The `end_of_service`
-  object is only present on Mainnet, where end of support is enforced
