📝 Walkthrough

Walkthrough

These changes update the documentation version management system. The utility script is modified to use absolute URLs, update copyright information, and implement version entry cleanup logic, while the versions JSON file is updated to reflect the new latest version 26.04.00.

Version Management Updates ci/utils/update_doc_versions.py	Updated copyright year to 2025-2026; changed URL format from relative path "../{version}/" to absolute URL "https://docs.nvidia.com/cuopt/user-guide/{version}/"; added newline after json.dump() output; implemented logic to remove "latest" named entries and entries with preferred flag before inserting new version entry

34-39: Remove "preferred" key regardless of its value.
if version_entry.get("preferred"): won’t remove a preferred: false key, leaving inconsistent schema and potentially confusing downstream consumers that check key presence.

✅ Proposed fix

-        if version_entry.get("preferred"):
-            version_entry.pop("preferred", None)
+        if "preferred" in version_entry:
+            version_entry.pop("preferred", None)
