+<!--
+Usage:
+
+Change log entries are to be added to the Unreleased section under the
+appropriate stanza (see below). Each entry is required to include a tag and
+the Github issue reference in the following format:
+
+* (<tag>) \#<issue-number> message
+
+The tag should consist of where the change is being made ex. (x/staking), (store)
+The issue numbers will later be link-ified during the release process so you do
+not have to worry about including a link manually, but you can if you wish.
+
+Types of changes (Stanzas):
+
+"Features" for new features.
+"Improvements" for changes in existing functionality.
+"Deprecated" for soon-to-be removed features.
+"Bug Fixes" for any bug fixes.
+"Client Breaking" for breaking CLIs, Protobuf, gRPC and REST routes used by end-users/reporters.
+"API Breaking" for breaking exported APIs.
+"State Machine Breaking" for any changes that result in a different AppState given same genesisState and txList.
