Categories and Subcategories

The category property has been moved into a new extended property in the Public Stash API and is no longer available in other item APIs. It has been split into a more sensible form of category (a single string) and subcategories (an array of strings). These properties may not always appear if the item doesn't have a handled category.

Example:

{
    ...
    "extended": {
        "category": "jewels",
        "subcategories": [
            "abyss"
        ]
    }
    ...
}

Prefix and Suffix counts

The Public Stash API now includes counts of explicit prefixes and suffixes on applicable items. You may find these under the new extended property. The prefixes (integer) and suffixes (integer) properties are only included if the count is non-zero. Uniques are also excluded from having these properties.

Example:

{
    ...
    "extended": {
        "prefixes": 2,
        "suffixes": 2
    }
    ...
}

Blight Map Series

New Blight maps will use the mn=5 parameter in their image URLs.

Blighted Maps

Maps can now be Blighted, replacing any monsters inside with a large-scale Blight encounter. These maps are prefixed with "Blighted" similar to Shaped or Elder maps and have some special mods associated with them. A map cannot be Blighted as well as Shaped or Elder, they are each exclusive.

Blighted maps have a mb=1 parameter set in their image URL in order to render a different image than usual.
The URL for a Blighted Siege Map looks like: https://web.poecdn.com/image/Art/2DItems/Maps/Atlas2Maps/New/Boulevard.png?scale=1&w=1&h=1&mn=5&mt=15&mb=1&v=3
