A quick reminder regarding the Splice version 0.6.x updates: **Wallet SDK v0.x is incompatible with Splice v0.6 and Daml v3.5.** If you are using the Wallet SDK, you will need to update to **Wallet SDK v1.1 or later** (latest at time of posting is v1.2.1) to keep everything functioning correctly. The Wallet SDK v1.x is backwards compatible with Splice v0.5.X, but not with v0.4.X.

To help with the transition, please check out the step-by-step instructions in the **[Wallet SDK v0 to v1 Upgrade Guide](https://docs.digitalasset.com/integrate/devnet/wallet-sdk-v1-migration-guide/index.html).**

**We previously announced the details of the new SDK version and compatibility in the forum.
