### Breaking
- `custom/script`: now doesn't hide failing script if it's output is not changing ([`#2636`](https://github.com/polybar/polybar/issues/2636)). Somewhat similar behaviour can be imitated with `format-fail`, if necessary.

- If the `exec` command produced no output and exited with a non-zero exit code the module is no longer completely empty, but just has an empty `%output%` token. If you relied on this behavior to hide the module under certain circumstances, make sure the script exits with an exit code of zero. ([`#2857`](https://github.com/polybar/polybar/discussions/2857), [`#2861`](https://github.com/polybar/polybar/pull/2861))
### Build
- Respect `CMAKE_INSTALL_PREFIX` when installing default config ([`#2770`](https://github.com/polybar/polybar/pull/2770))

### Changed
- `custom/script`: No longer produces a completely empty module if the `exec` command failed. It only produces an empty module if the script had a zero exit code. ([`#2857`](https://github.com/polybar/polybar/discussions/2857), [`#2861`](https://github.com/polybar/polybar/pull/2861))
