+Added new environment variables for `tauri signer sign` command, to align with existing environment variables used in `tauri build`, `tauri bundle` and `tauri signer generate`
+- `TAURI_SIGNING_PRIVATE_KEY`
+- `TAURI_SIGNING_PRIVATE_KEY_PATH`
+- `TAURI_SIGNING_PRIVATE_KEY_PASSWORD`
+
+The old environment variables are deprecated and will be removed in a future release.
