v1.17.1

What changed

See CHANGELOG.md
for this release's entry, written for the person installing it.

Verify what you downloaded

Every artifact below is published with its SHA-256 in a public,
append-only transparency log, a keyless cosign signature, a SLSA
build-provenance attestation, and a CycloneDX SBOM.

• Commands to check all of it: https://pollis.com/artifacts
• Whether this release rebuilt bit-for-bit from source:
  https://pollis.com/assurance

The installers verify automatically — install.sh requires the hash
it downloaded to appear in the transparency log at a different
origin from the CDN, and runs cosign when it is available.
