Dash is a pioneer project and the creator of masternodes with couple of more technologies but they haven't been inventing anything lately
Lets see what Dash invented lately :
ChainLocks : providing Dash network protection against 51% attacks, making it more secure then Bitcoin. Dash is the only proof of work cryptocurrency that has this kind of additional protection against 51% attacks. It is also the reason why Coinbase Pro only requires
two transaction confirmations on Dash deposits (making Dash 12 times faster with regards to deposits then Bitcoin).
LLMQ-based InstantSend : making 90% of Dash transactions InstantSend transactions (send, receive and spend within a few seconds) without any additional cost and protected against double spending. InstantSend used to be optional with additional fees, it is now active by default without any additional fees.

Dash Platform will change Dash from functioning as just a cryptocurrency, to Dash functioning as a platform where decentralized services and decentralized apps can be run on. This has been in development for 5 years now and is currently on Dash Public Testnet (named Evonet). This will also introduce decentralized identity, decentralized blockchain usernames, storage of metadata on masternodes (Dash Drive) and a decentralized API (DAPI).

Dash has been inventing plenty lately, you just did not notice it. Most likely because you were not paying attention to Dash.
