Dashcoin has been updated to v.1.0.2, which includes the following features:
Transaction history for simplewallet and Wallet JSON RPC
Reset command for simplewallet and Wallet JSON RPC
Various simplewallet improvements
The "reset" command is a handful tool in case you would like to resynchronize your wallet's data from scratch. This command was introduced to avoid deleting the wallet.bin file in case the re-synchronization is required.
The transaction history can be obtained through "list_transfers" command in simplewallet or "get_transfers" method in Wallet RPC. It returns the information regarding all incoming and outgoing transactions. The method provides an easy way for the users or services to recheck all the wallet's operations.
