In This Release

This is update is focused on better RIDE 4dApps developer experience.

• dApp's scripts can now be invoked through alias:

invokeScript({
            dappAddress: "superweb3app",
            call:{function:"gowaves",args:[]}, payment: []},
            userSeed
            )

• New @Default annotation function to dApp added. This allows client to invoke dApp's by its address/alias

invokeScript({
            dappAddress: "superweb3app",
            call:null,
            userSeed
            )

The way of defining default function in script is subjected to change in the future releases.

• Binary operations order during compilation changed to ones in Java
• Seriliazation of invokeScriptTransaction has been changed
• Various node & blockchain optimizations
• Bugfixes
