# Changelog ## [Unreleased] ### Features + [\#8590](https://github.com/cosmos/cosmos-sdk/pull/8590) File watcher for cosmovisor. Instead of parsing logs from stdin and stderr, we watch the `/data/upgrade-info.json` file updates using polling mechanism. ### Improvements + [\#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. ## v0.1 2021-08-06 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. ## Features * [\#9652](https://github.com/cosmos/cosmos-sdk/pull/9652) Add backup option for cosmovisor.
