+#### `ipfs dag stat` deduping statistics
+
+`ipfs dat stat` now accept multiple CIDs and will dump advanced statistics
+on the number of shared blocks and size of each CID.
+
+```console
+$ ipfs dag stat --progress=false QmfXuRxzyVy5H2LssLgtXrKCrNvDY8UBvMp2aoW8LS8AYA QmfZDyu2UFfUhL4VdHaw7Hofivmn5D4DdQj38Lwo86RsnB

+
+`ipfs --enc=json dag stat`'s keys are a non breaking change, new keys have been added but old keys with previous sementics are still here.
