* [\#10649](https://github.com/cosmos/cosmos-sdk/pull/10649) Customize backup directory. Added new env variable: `DAEMON_BACKUP_DIR`. If it is set, cosmovisor will backup the app data in ``DAEMON_BACKUP_DIR` before running the update.
* [\#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.
* [\#10036](https://github.com/cosmos/cosmos-sdk/pull/10036) Improve logs when downloading the binary.
* [\#10217](https://github.com/cosmos/cosmos-sdk/pull/10217) Replacing logging to use zerolog.
