New PortalExtensionHookDataExport portal extension hook type added — when configured on export-capable portal blocks, the portal delegates the export action (CSV/Excel/PDF download) to the external source instead of generating the file itself
New PortalExtensionHookVisualizationMetadata portal extension hook type added — invoked before fetching data with the same portal context as the data hook, returns per-meter/contract visualization metadata (type_options, intervals, data_range)
intervals field on PortalExtensionHookConsumptionDataRetrieval, PortalExtensionHookCostDataRetrieval, and PortalExtensionHookPriceDataRetrieval deprecated — prefer declaring a sibling visualizationMetadata hook so supported intervals can vary per meter/contract
use_static_ips field deprecated on all portal extension hook types — prefer secure_proxy
New object enum value added to portal extension component option type, plus new fields (primitive sub-field declarations) and repeatable (array-of-entries flag) properties — enables structured object-typed and list-typed component options
