OP_RETURN Relay Policy Changes Merged

Bitcoin Core has merged PR #32406 which updates relay policy to:

  • uncap the OP_RETURN data size limit, previously set to 80 bytes
  • allow multiple OP_RETURN outputs in a single transaction
  • marks -datacarrier and -datacarriersize options as deprecated (but does not remove them)

This change will be included in Bitcoin Core v30.
