 # CHANGELOG for HED specification
 
+## Changes for HED specification 3.2.0
+- The `Inset` tag was introduced to mark intermediate points in events of temporal extent.
+- Partnered schemas were introduced using the `withStandard` schema header attribute
+and the `rooted` schema attribute.
+- The curly brace annotation for sidecars was introduced.
+
+## Changes for HED specification 3.1.1
+This release is added additional minor corrections and 
+clarifications in the specification document and does not include any enhancements from version 3.0.0.

+### 5.3.2. Using `Inset`
+
+The `Inset` tag group marks an intermediate point in an event of temporal extent
+defined by `Onset` and `Offset`.
+Like the `Offset`, the `Inset` tag is anchored by a `Def` tag or `Def-expand` tag group
+that is the anchor of its enclosing `Onset`.

+The `Inset` tag group may contain an additional internal tag group in addition to the
+anchor `Def` tag. This internal tag group usually contains annotations specific 
+to this instance of the event. As with all HED tags and groups, order does not matter.
