devs want to introduce new opcodes to segwit that reintroduce malleability into segwit
I've heard this before, but couldn't any detailed info. Do you know any info or which opcodes which you believe will reintroduce malleability?
franky1 is known to be a drama queen about everything when SegWit is involved

he may be talking about BIP-118 which "proposes" addition of a new sighash called NoInput. i don't know what it has anything with malleability but i have seen some concerns raised about it specially for when you do address reuse. although like many of the BIPs it is just a proposal that is not accepted.
