• Logging

• Utils

  • Fixed8: A new class extending bignumber.js that replaces all value storage in neon-js
  • This class is now used for all classes that involves coin values with decimal places.
  • Comes with helper methods such as toHex and fromHex.

    import {u} from '@cityofzion/neon-js'
    // accepts numbers or string
    const num1 = new u.Fixed8(123.4567)
    const num2 = u.Fixed8.fromHex('0000000005f5e100') // 1
    
    const num3 = num1.add(num2) // immutable
    console.log(num3.toString()) // '124.4567'
    

• Wallet

  • Claims is now a ES6 class. While it does not have any spceial methods for it now, it is one of the high level objects that we will be working with in neon-js. This allows easy creation of Claims using the constructor by passing in a CLaims-like javascript object.
  • components have been created for the minor sub-components found in Claims and Balance. These methods are useful for us to rapidly create components that are usable with neon-js methods. Refer to the wallet section for more information.
  • BREAKING Excess NEP2 functions are now fully deprecated. The list is encryptWifAccount, generateENcryptedWif, encryptWIF, decryptWIF.

• Transaction

  • Update all methods to conform with the new Fixed8 classes. This also means that neon-js will not be compatible with just normal javascript objects anymore.

• API

  • BREAKING Update external API libraries (neonDB and neoscan) to return Balance and Claims objects. Fixed8 will be used in the new models, making arithmetic operations very different from normal javascript numbers.
  • A bug has been discovered in getPrice. While it works for NEO and GAS, it will not work for any of the NEP5 tokens. getPrices has been fixed for this bug. However, there is no easy fix for getPrice and thus, we will move forward with deprecating getPrice in favor of getPrices.

• Fixes

  • fix getPrices by adding a limit=0 to the query.
  • fix default Account.contract field not having the required shape.
  • fix transaction attribute being deserialized wrongly.
