PCoin v1.2.3

PCoin v1.2.3 brings the new struck coin mark to every platform: both Android
apps, the Windows installer and its shortcuts, the tray icon, and pc.am.

The node binaries are byte-identical to v1.2.1 and v1.2.2. No consensus code
changed. The packaging script asserts their SHA-256 rather than claiming it, so
a rebuild that altered them would fail rather than ship quietly:

d73e1f6f12771a4d6dc7ca65ce4fc8b6f94a615c3f6abc841c7d3a7c1c8e211e  bitcoind.exe
d48b90cfce1ee456e84044cc6e8c961415800211d9974f76026ff9bc5c061fac  bitcoin-cli.exe
5114db61a99deb7fb5c0c1cc365e09188924eed89eb2486555f6f90fe3bff9c3  bitcoind
79c19c1dd10b2aa3451ff9d7649633ace1e77be3dea06d35a2b3e36e9132f7e4  bitcoin-cli

Also fixed since v1.2.2

install.ps1 was broken. The release archive lays binaries out as
pcoin-<ver>\bin\*.exe and the script copied that tree verbatim into
C:\PCoin, so they landed in C:\PCoin\bin while the tray, the scheduled task
and the script's own next line all looked in C:\PCoin. It reported success and
produced an install that could not start a node. It now locates bitcoind.exe
wherever it is in the archive and flattens from there.

Downloads

Every file is published under two names with identical bytes: one carrying the
version, one without. The version-less name is what pc.am links to, so those
links keep working when the next release lands.

Android

Both APKs are signed with the release key
2dc08424507c08c12f5afb7ce7328d5f4fec772dde04de40d69a69e8dcaccb32.

Android refuses to install over an app signed with a different key. If you
already run a build from source signed with this repo's debug key you must
uninstall first, and uninstalling destroys the wallet in app-private
storage. Write your recovery phrase down before you do that.

Verify what you downloaded

sha256sum --ignore-missing -c SHA256SUMS

These checksums prove the file is intact. They are not signatures, and the
builds are not reproducible yet -- see doc/REPRODUCIBLE-BUILDS.md.
