   Possible typos and grammar issues:

   • “MuSig2 fields for PSBT as of v30.0” -> “MuSig2 fields for PSBT are supported as of v30.0” [missing verb; current phrase is fragment and may be unclear]
   • “and signing in v31.0” -> “and signing is supported as of v31.0” [second clause lacks a verb, making the sentence grammatically incomplete]
