Sumokoin developer team has churned out Aomori release point 1 that includes fixes for various important wallet bugs. Newer user interface will be made available in next update that will be released soon. Same goes for the LITE wallet that will be released immediately after GUI update. Lite wallet does not require you to download entire blockchain as it only downloads the headers. This release is mainly to fix various wallet bugs for more reliable / stable CLI / LITE / GUI wallets and to make sure blockchain synchronization work properly after hardfork v3.
