Upgrade Wallet SDK Version to latest before the MainNet upgrade on December 10th

To all Wallet SDK users,

Versions 0.17.0 and lower of the Wallet SDK are not fully compatible with Splice v0.5.1. Therefore it’s necessary to ensure that the Wallet SDK is updated to the newest version, 0.18.1 (release notes here), before the MainNet upgrade on December 10th. Continued use of older versions may cause errors after the MainNet upgrade.
