 ### Line Highlight
 
+::: note
+This is deprecated. It's disabled by default in `v0.10.0` and will be removed in the next minor. Consider use [`transformerNotationHighlight`](https://shikiji.netlify.app/packages/transformers#transformernotationhighlight) instead.

 In addition to the features of `shikiji`, this plugin also supports line highlighting. You can specify line numbers to highlight after the language name in the format `{<line-numbers>}` - a comma separated list of `<line-number>`s, wrapped in curly braces. Each line number can be a single number (e.g. `{2}` highlights line 2 and `{1,4}` highlights lines 1 and 4) or a range (e.g. `{5-7}` highlights lines 1 through 7, and `{1-3,5-6}` highlights lines 1 through 3 and 5 through 6). For example:
