+## v0.2.0
+
+- BREAKING disconnect no longer disconnects the underlying block device and
+  instead marks the partition as disconnected. This does not propagate to
+  subpartitions (#9 @dianaoigo)
+- BREAKING `connect` and `subpartition` no longer return pairs. Instead,
+  `connect` returns a partition representing the whole block device.
+  `subpartition` then takes labelled arguments `~start` and `~len`. While the
+  "split" semantics has some nice properties it does not fit very well with how
+  partitions are specified in partition tables (#13 @reynir)
+- mirage-block-partition-mbr is simplified and no longer checks for overlapping
+  partitions. The module may be removed or revised in a future release.
