Note

Low Risk
Release bookkeeping only: version strings and CHANGELOG.md are updated, with no functional code changes beyond the reported version.

Overview
Cuts the 8.18.0 release.

Updates the release manifest and relay/version/version.go from 8.17.7 to 8.18.0, and appends the 8.18.0 entry to CHANGELOG.md with the aggregated feature and fix notes.
