Yeah, that's what led me down the path of finding the .lua file with the new API calls.

Unfortunately, I'm not finding a proper replacement for GetWorldMapTransforms(). This function resides in HereBeDragons, which is used by a lot of addons (including TomTom, HandyNotes, etc):

    local function processTransforms()
        wipe(transforms)
        for _, tID in ipairs(GetWorldMapTransforms()) do
            local terrainMapID, newTerrainMapID, _, _, transformMinY, transformMaxY, transformMinX, transformMaxX, offsetY, offsetX, flags = GetWorldMapTransformInfo(tID)
            -- flag 4 indicates the transform is only for the flight map
            if band(flags, 4) ~= 4 and (offsetY ~= 0 or offsetX ~= 0) then
                local transform = {
                    instanceID = terrainMapID,
                    newInstanceID = newTerrainMapID,
                    minY = transformMinY,
                    maxY = transformMaxY,
                    minX = transformMinX,
                    maxX = transformMaxX,
                    offsetY = offsetY,
                    offsetX = offsetX
                }
                table.insert(transforms, transform)
            end
        end
    en

Any clues?
