- Line 6: Update the frontmatter description for the KubeCon + CloudNativeCon
Japan 2026 article to say “Yokohama” instead of “Tokyo,” matching the location
already used in the article body.
- Around line 25-27: Update the v1.2.0 references in the trip announcement to
avoid presenting it as the current stable release; describe it as upcoming, use
the exact v1.2.0-rc.1 identifier, or retain v1.1.2 as the stable version until
GA.
