+# Multiple memory safety issues in insert_row
+
+When inserting rows from an iterator at a particular index, `toodee` would shift
+items over, duplicating their ownership. The space reserved for the new elements
+was based on the `len()` returned by the `ExactSizeIterator`.
+
+This could result in elements in the array being freed twice if the iterator
+panics. Uninitialized or previously freed elements could also be exposed if the
+`len()` didn't match the number of elements.
+
+These issues were fixed in commit `ced70c17` by temporarily setting the length
+of the array smaller while processing it and adding assertions on the number
+of elements returned by the iterator.
