Bitcoin Core 28.4 release guide cover

This guide explains Bitcoin Core 28.4 release in plain English. It summarises the important changes, who they affect and what should be checked before an upgrade.

TL;DR

  • What it is: Bitcoin Core 28.4 is a focused maintenance release for operators remaining on the 28.x branch. It backports fixes for unnamed legacy-wallet migration, wallettool createfromdump failure cleanup and related migration bugs, removes one DNS seed and updates deterministic-build and continuous-integration tooling.
  • Why it matters: Bitcoin Core 28.4 improves delicate legacy-wallet failure paths while maintaining the older branch boundary. Rehearse migrations and negative cases on copies before allowing the release near irreplaceable wallet material.
  • Current position: Require a second reviewer and explicit rollback or expiry, and pause payments, signing or network-dependent services until post-change evidence is complete.

Bitcoin Core 28.4 release in simple English

Bitcoin Core 28.4 release: The release includes cleanup for relative-wallet migration failure and further corrections to the backported wallet changes. Validate names, paths, watch-only state and backup results.

Simple example

A node operator is checking Bitcoin Core 28.4 release. Inventory the default wallet explicitly and test both successful migration and controlled failure from verified copies.

Key terms in plain English

Bitcoin Core:
Widely used software that validates Bitcoin and can provide wallet, network and operator tools.
Node:
A computer running Bitcoin software that checks data and communicates with other peers.

Unnamed wallets

Migration of an unnamed legacy wallet is corrected. Inventory the default wallet explicitly and test both successful migration and controlled failure from verified copies.

Dump cleanup

wallettool createfromdump no longer deletes the wallets directory on the affected unnamed failure. Stage dump imports away from production and confirm unrelated wallet files survive negative cases.

Backport fixes

The release includes cleanup for relative-wallet migration failure and further corrections to the backported wallet changes. Validate names, paths, watch-only state and backup results.

Backport fixes: the fields, validation boundary and operational evidence that implementations need to agree.

Peer discovery

One DNS seed is removed. Confirm outbound connectivity and peer diversity through remaining discovery mechanisms rather than pinning availability to one source.

Build and CI

Guix signing-tool tests and CI platform versions are updated. Custom builders should pin the branch, dependencies and hashes and compare reproducible outputs where supported.

Compatibility

The 28.x notes list Linux kernel 3.17+, macOS 11+ and Windows 7+ as tested baselines. Record the branch support decision and do not assume Core 29 or 30 features.

How specialists test it

Node operators test the release on a representative non-production system. They check startup, normal operation, failure handling and restart before changing a live node. Connected wallets, monitoring and mining services should also be checked.
