> Wallet SDK 1.2.1 release notes.

# 1.2.1

**Released on May 13th, 2026**

* fixes for Wallet SDK type inference

*a typing issue around optional `extend` options and SDK initialization was fixed to improve TypeScript inference and reduce false-positive
type errors in consumer projects.*

* improved compatibility with unknown Canton versions

*when a newer/unknown Canton version is detected, the SDK stack now warns and falls back to a compatible client version instead of failing
immediately, making forward-compatibility smoother while still surfacing the warning.*

* hardened unauthenticated connection error handling

*minor exception handling edge cases in unauthenticated connection detection were fixed to avoid misleading failures.*
