Cosmos SDK v0.42.8 "Stargate" Release Notes

This release includes various minor bug fixes and improvements, including:

• emit events for tx signature and sequence, so clients can now query txs by signature (`tx.signature='<base64_sig>'`) or by address and sequence combo (`tx.acc_seq='<addr>/<seq>'`),

• support other signing algorithms than `secp256k1` with `--ledger` in with the CLI `keys add` command,

• add missing documentation for CLI flag `--output json/text` to all `tx` cli commands.

See the Cosmos SDK v0.42.8 milestone on our issue tracker for the exhaustive list of all changes.
