Bitcoin Core 29.4 is available, with official notes focused on bug fixes.

Bitcoin Core version 29.4 offers bug fixes and performance improvements for node operators.

Release Details

The Bitcoin Core project announced version 29.4 on July 13, 2026. This update targets issues in node software operation.

Binaries are available at https://bitcoincore.org/bin/bitcoin-core-29.4/.

Supported platforms include Linux Kernel 3.17 or later, macOS 13 or later, and Windows 10 or later, as stated in the release notes.

Confirmed Changes

Official release notes at https://bitcoincore.org/en/releases/29.4/ list various bug fixes, performance improvements, and updated translations.

A key fix addresses the chainstate database repeatedly rewriting large portions of itself. This caused excessive disk reads and writes during normal operation.

To apply the update, users shut down the prior version completely. Then they install or copy over the new binaries.

Context and Timeline

This follows Bitcoin Core 31.1, published on July 8, 2026, as a bug-fix release. See https://bitcoincore.org/en/2026/07/08/release-31.1/.
