a wallet doesn't have to change, updated each day. 2 month ago can still be considered new. they are usually updated as a new feature is required or a bug is found. and bugs are found when more people use the wallet and as far as altcoin wallets go, people rarely use them. they mostly keep it on their exchange account to be able to sell it fast enough or use a web wallet if they can find it.
There wasn't a new release for many months now, and the last commit was 2 months ago, meaning that the project is barely being worked on.
I would like this to change, since the Electrum on BTC has itnroduced many changes, it should be added to Dash too.
