Dinero v8.1.3
v8.1.3 is a focused desktop startup reliability release. It contains no new consensus activation and does not change the covenant activation height or AssumeUTXO trust anchors.
Desktop startup fix
- Prevent the Qt application and MainWindow from independently launching duplicate embedded daemons.
- Eliminate the startup race in which a slow, legitimate daemon could lose a second datadir/port race and then be killed by retry cleanup.
- Preserve a single application-owned daemon startup path while retaining an explicit MainWindow-owned fallback for tests and alternate embeddings.
The regression was verified two ways: an always-on Release/NDEBUG policy test executed in CI, and a controlled field A/B test on a byte-identical copy of the real 205 GB datadir. With an intentional 15-second launch delay, v8.1.2 made three launch attempts and ran two daemon children concurrently; v8.1.3 made exactly one launch, one daemon PID, and reached ready RPC with five peers.
Snapshot bootstrap
The primary V4 AssumeUTXO snapshot remains height 84,131, SHA-256 7defc1897055ba24a92985e30ce35123181debc272c86e5fd2d190e436802845. Existing lifecycle fallbacks remain supported. No snapshot format, anchor, or consensus state changed in this release.
Additional desktop packages
The existing v8.1.3 release now also includes:
- Linux x86_64 graphical wallet/full-node packages as an AppImage, Debian/Ubuntu
.deb, and portable Qt archive. - Intel macOS graphical wallet/full-node packages as a Developer ID-signed, Apple-notarized and stapled DMG and app ZIP.
These packages were built from the immutable v8.1.3 source commit a9576e07c031e13f497eb43a7b42dc963251c16c. Only reviewed release-packaging tooling was added afterward; application and consensus sources were not changed. Platform-specific desktop checksum files accompany the new assets.
Upgrade guidance
Users of the v8.1.2 macOS Qt wallet should upgrade to v8.1.3. Back up wallet material before upgrading and do not delete an existing datadir or snapshot lifecycle files. Verify downloads with the platform-specific SHA256SUMS-* files.
