 ## [1.2.0] - 2022-06-02
 
 ### Added
 
- - Added new function `tealSign` to generate `ed25519` signatures that can be verified by a teal program. See also: [ed25519verify opcode](https://developer.algorand.org/docs/get-details/dapps/avm/teal/opcodes/#ed25519verify) and [algosdk.tealSign](https://algorand.github.io/js-algorand-sdk/modules.html#tealSign)
