Highlight of the Release

• Fixed cache invalidation headers to use relative URLs instead of absolute URLs
• Improved compatibility with various CDN and proxy configurations

No migration steps are required for this update. The change to cache invalidation headers is handled automatically by the Ghost platform after updating to v5.116.1.
