- `usethis show` commands will no longer hard-wrap outputs, which gave invalid results in some cases, e.g. when running `usethis show sonarqube` with long `sonar.projectKey` fields.

- Fallback icons (e.g. `√`, `□`, `i`, `×`, `!`) for message icons (`✔`, `☐`, `ℹ`, `✗`, `⚠`) are now used for terminals which don't support unicode.

- Identical warnings will now never display twice for the same command.

- When a backend is not being used, the inferred version of Python based on the current interpreter is now compared with the `requires-python` bounds from `pyproject.toml`. If there is a mismatch, a warning is now emitted.

- The `tomli` dependency on `codespell` is only declared as a dependency for Python versions 3.10 and below, since for versions 3.11 onwards, `codespell` uses `tomllib` from the standard library. This is based on the `requires-python` bounds from `pyproject.toml` if available, otherwise by the current interpreter.

- As per the notes for 0.16.0, Version 0.18.13 of ruamel.yaml introduced a regression relating to indentation. The new versions 0.19.0 and 0.19.1 of ruamel.yaml are now also excluded as dependency versions until this is addressed in a future release.

- Rule management logic is now abstracted into the `Tool` class, reducing duplication between the logic used for deptry and Ruff.

- Import Linter contracts for development have been moved from `pyproject.toml` to `.importlinter` for tidiness.
