Upstream changlog:
https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-0.18.0.md
Notable port changes:
- Disable BIP70, form changlog:
"A new --disable-bip70 option may be passed to ./configure to prevent
Bitcoin-Qt from being built with support for the BIP70 payment protocol
or from linking libssl. As the payment protocol has exposed Bitcoin Core
to libssl vulnerabilities in the past, builders who don't need BIP70
support are encouraged to use this option to reduce their exposure to
future vulnerabilities."
- Major lib bump: libbitcoinconsensus
- WANTLIB png clean up
- devel/protobuf is not more needed with disabled BIP70
