News category list requests can target the root news hierarchy or a nested bundle path. A root request lists every top-level bundle and category. Supplying a bundle path lists only the bundles and categories directly below that bundle, which lets clients browse a hierarchy one level at a time.
For protocol transaction 370 (NewsCategoryNameList), send the path parameter
as / for the root or as a slash-separated bundle path for a nested bundle.
For example:
/
/Releases
/Releases/2026
If the hierarchy contains bundle /Releases/2026 with categories
Announcements and Maintenance, a category-list request for /Releases/2026
returns those two names and omits sibling categories from /Releases or /. A
request for a missing path returns the same unsupported path error as other
invalid news lookups.
