+ [\#10533](https://github.com/cosmos/cosmos-sdk/pull/10649) Added environmental variable `DAEMON_BACKUP_DIR` to allow node to set a custom backup directory.
+ [\#10458](https://github.com/cosmos/cosmos-sdk/pull/10458) Fix version when using 'go install github.com/cosmos/cosmos-sdk/cosmovisor/cmd/cosmovisor@v1.0.0' to install cosmovisor.
+ [\#8590](https://github.com/cosmos/cosmos-sdk/pull/8590) File watcher for cosmovisor. Instead of parsing logs from stdin and stderr, we watch the `<DAEMON_HOME>/data/upgrade-info.json` file updates using polling mechanism.
+ [\#9999](https://github.com/cosmos/cosmos-sdk/pull/10103) Added `version` command that returns the cosmovisor version and the application version.
+ [\#9973](https://github.com/cosmos/cosmos-sdk/pull/10056) Added support for pre-upgrade command in Cosmovisor to be called before the binary is upgraded. Added new environmental variable `DAEMON_PREUPGRADE_MAX_RETRIES` that holds the maximum number of times to reattempt pre-upgrade before failing.
+ [\#10018](https://github.com/cosmos/cosmos-sdk/pull/10018) Strict boolean argument parsing: cosmovisor will fail if user will not set correctly a boolean variable. Correct values are: "true", "false", "" (not setting) - all case not sensitive.
This is the first release and we started this changelog on 2021-07-01. See the (README)[https://github.com/cosmos/cosmos-sdk/blob/release/cosmovisor/v0.1.x/cosmovisor/CHANGELOG.md] file for the full list of features.
