 ### Client Breaking Changes
 
+* [\#9859](https://github.com/cosmos/cosmos-sdk/pull/9859) The `default` pruning strategy now keeps the last 362880 blocks instead of 100. 362880 equates to roughly enough blocks to cover the entire unbonding period assuming a 21 day unbonding period and 5s block time.
 * [\#9594](https://github.com/cosmos/cosmos-sdk/pull/9594) Remove legacy REST API. Please see the [REST Endpoints Migration guide](https://docs.cosmos.network/master/migrations/rest.html) to migrate to the new REST endpoints.
 * [\#9781](https://github.com/cosmos/cosmos-sdk/pull/9781) Improve`withdraw-all-rewards` UX when broadcast mode `async` or `async` is used.
 * [\#9785](https://github.com/cosmos/cosmos-sdk/issues/9785) Missing coin denomination in logs

+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):
+
+"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 Protobuf, gRPC and REST routes used by end-users.
+"CLI Breaking" for breaking CLI commands.
+"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.

 *Note: If new versions of the application are not set up to run in-place store migrations, migrations will need to be run manually before restarting `cosmovisor` with the new binary. For this reason, we recommend applications adopt in-place store migrations.*

+# Cosmovisor v0.1.0 Release Notes
+
+This is the first tracked release of Cosmovisor. It contains the original behavior of scanning app stdin and stdout.
+Since the original design, this release contains one important feature: state backup. Since v0.1, by default, cosmovisor will make a state backup (`<app_directory>/data` directory). Backup will be skipped if `UNSAFE_SKIP_BACKUP=true` is set.
+
+Updates to this release will be pushed to `release/cosmovisor/v0.1.x` branch.
+
+Please see the [CHANGELOG](https://github.com/cosmos/cosmos-sdk/blob/release/cosmovisor/v0.1.x/cosmovisor/CHANGELOG.md) for more details.
