Fixes since rc1:
- xpay: Corrected the CLTV values in blinded paths which sometimes caused spurious failures.
- onchaind: Correctly collect our own (delayed) funds if we have a unilateral close when we are still offering a lease.
- Protocol: We now renegotiate an interrupted close, even if we don't need it, instead of sending an error.
See the CHANGELOG for more details.
