Bitcoin Core 30.3 released with bug fixes

Bitcoin Core version 30.3 is now available for download, according to an announcement from the project published July 8, 2026.

The project said the release includes bug fixes. It directed users to the release notes for the specific fixes included in version 30.3.

The announcement did not provide further technical detail in the supplied information. Users considering the update should consult the project’s release notes and assess the changes for their own setup.

Release availability and scope

Bitcoin Core is the software project announcing the 30.3 release. The stated scope of the update is bug fixes, while the release notes are the referenced source for the underlying details.

No performance, security, compatibility, or network-wide impact claims can be drawn from the announcement alone. The supplied release information confirms availability and the presence of bug fixes, but does not enumerate them.

What users can verify

Users can verify the version number and review the release notes before deciding whether to install the software. That review is particularly relevant where an operator needs to understand changes affecting an existing deployment.

Update considerations

As with software updates generally, users should review official materials and follow their own operational procedures before making changes.
