+> **Upgrade notice for `stet-cli` users** — versions **0.1.0** and **0.1.1**
+> have been yanked from crates.io. Both shipped without embedded-resource
+> registration, so the `stet` binary fell back to a PNG-writing rasterizer
+> whenever you opened a PostScript file in the interactive viewer. **0.1.2**
+> is self-contained and fixes this. If you previously ran `cargo install
+> stet-cli`, upgrade with:
+>
+> ```
+> cargo install stet-cli --force
+> ```
+>
+> The `stet` library crate (used via `Interpreter`) was never affected.
