• Add BigDecimal support.
  • Includes a new BigDecimal(bigInt: BigInt) constructor.
  • Includes a BigDecimal.fromString("0.25") constructor.
  • Includes +, -, *, / and == operators.
• BigInt changes:
  • Add a bigInt.divDecimal(n: BigDecimal): BigDecimal method to BigInt.
  • Add == / .equals operator for BigInt.
• Add APIS for mapping over IPFS files with (potentially) many values:
  • ipfs.map(hash: string, callback: string, userData: Value, parameters: string[]).
  • ipfs.mapJSON(hash: string, callback: string, userData: Value) for files with JSON values (e.g. http://jsonlines.org).

  • Make ipfs.cat return null on errors, allowing mappings to handle this.
