Tapscript: New Opcodes, Reduced Limits and Covenants #67450 https://blog.blockstream.com/tapscript-new-opcodes-reduced-limits-and-covenants

Super cool to see support coming to miniscript! Miniscript makes it a lot easier to write, analyze, and experiment with bitcoin script. Having some covenant support in elements miniscript will (hopefully) make it easy for people to implement cool usecases and play with neat applications of covenants. Would be really cool to see a coinpool implementation in the wild that we can poke at. Should really help covenant research and discussion for bitcoin!

So do we have feature parity with Ethereum yet?
