-<!--
-Guiding Principles:
-
-Changelogs are for humans, not machines.
-There should be an entry for every single version.
-The same types of changes should be grouped.
-Versions and sections should be linkable.
-The latest version comes first.
-The release date of each version is displayed.
-Mention whether you follow Semantic Versioning.
-
-Usage:
-
-Change log entries are to be added to the Unreleased section under the
-appropriate stanza (see below). Each entry should ideally include a tag and
-the Github issue reference in the following format:
-
-* (<tag>) \#<issue-number> message
-
-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):
+# Change log
 
-"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 CLI commands and REST routes used by end-users.
-"API Breaking" for breaking exported APIs used by developers building on SDK.
-"State Machine Breaking" for any changes that result in a different AppState given same genesisState and txList.
