 ### Features
 
-| Flag              | Description                           | Dependencies
-| ----------------- | ------------------------------------- | ------------
-| `default`         | Enables the `compact_strains` feature |
-| `compact_strains` | Storing internal strain values in a plain Vec introduces an out-of-memory risk on maliciously long maps (see [/b/3739922](https://osu.ppy.sh/b/3739922)). This feature stores strains more compactly, but comes with a ~5% loss in performance. |
-| `sync`            | Some gradual calculation types can only be shared across threads if this feature is enabled. This adds a performance penalty so only enable this if really needed. |
-| `tracing`         | Any error encountered during beatmap decoding will be logged through `tracing::error`. If this feature is **not** enabled, errors will be ignored. | [`tracing`]
+| Flag          | Description         | Dependencies
+| ------------- | ------------------- | ------------
+| `default`     | No features enabled |
+| `raw_strains` | With this feature, internal strain values will be stored in a plain `Vec`. This introduces an out-of-memory risk on maliciously long maps (see [/b/3739922](https://osu.ppy.sh/b/3739922)), but comes with a ~5% gain in performance. |
+| `sync`        | Some gradual calculation types can only be shared across threads if this feature is enabled. This feature adds a small performance penalty. |
+| `tracing`     | Any error encountered during beatmap decoding will be logged through `tracing::error`. If this feature is **not** enabled, errors will be ignored. | [`tracing`]
