The President of the Miniverse

This release contains a fix to a known issue with the database which caused excessive database usage (>20gb when it should be ~8gb) and missing beacon state errors whilst syncing.

This release is compatible with existing databases, but you must re-sync if you wish to benefit from these fixes.

To reiterate, to repair a broken Lighthouse database please re-sync (lighthouse bn --purge-db) using this release.

  • Prevents releases from indicating the the git tree is dirty in the release tag.

Binaries

Binaries are supplied for two platforms:

• x86_64-unknown-linux-gnu: AMD/Intel 64-bit processors (most desktops, laptops, servers)
• aarch64-unknown-linux-gnu: 64bit ARM processors (Raspberry Pi 4)

Additionally there is also a -portable suffix which indicates if the portable feature is used:

• Without portable: uses modern CPU instructions to provide the fastest signature verification times (may cause Illegal instruction error on older CPUs)
• With portable: approx. 20% slower, but should work on all modern 64-bit processors.
