Mark CXXVII

The Trail Wider

Shipped April 26, 2026

What it is

Per-category RSS 2.0 feeds at /rss/[category]. Sister to Mark LXIV /rss.xml (which emits every shipped Mark). Niche subscribers can now follow only the categories they care about: /rss/player-facing, /rss/tiers, /rss/growth, /rss/infrastructure, /rss/community, /rss/lifecycle. Stable URLs use the CATEGORY_SLUG mapping (Mark LXV) — same slugs the public /roadmap/category/[slug] pages use. Hand-rolled XML mirrors /rss.xml shape exactly so existing subscribers can opt into a sub-feed without surprises.
