 ## Version `Unreleased`
 
 * ![Feature][badge-feature] Added support for converting `HTMLBlock` nodes to and from `Markdown.HTMLBlock` when using Julia 1.14+, where the corresponding stdlib type is available.
+* ![Feature][badge-feature] Added support for converting `HTMLInline` nodes to and from `Markdown.HTMLInline` when using Julia 1.14+, where the corresponding stdlib type is available.
 * ![Feature][badge-feature] Added support for `Strikethrough` nodes when converting to/from the Markdown stdlib AST. This interop requires Julia 1.14+, because `Markdown.Strikethrough` is only available in the stdlib starting there. ([#31][github-31], [#32][github-32])

@@ -29,6 +29,7 @@ Due to the differences between the Markdown representations, the following thing
 - When converting a `Markdown.Table`, the resulting table will be normalized, such as adding empty cells to rows, to make sure that all rows have the same number of cells.
 - For links and images, the `.title` attribute is set to an empty string, since the standard library AST does not support parsing titles.
 - On Julia 1.14 and newer, `Markdown.HTMLBlock` values are converted to [`HTMLBlock`](@ref) elements. On older Julia versions, such nodes do not exist in the standard library AST.
+- On Julia 1.14 and newer, `Markdown.HTMLInline` values are converted to [`HTMLInline`](@ref) elements. On older Julia versions, such nodes do not exist in the standard library AST.
 
 ## Conversion to standard library representation
 
@@ -47,6 +48,7 @@ Due to the differences between the Markdown representations, the following thing
 - The standard library does not support storing the child nodes of [`Image`](@ref) elements (i.e. "alt text", `![alt text]()`) as AST, and it is instead reduced to a string with the help of the `Markdown.plain` function.
 - The standard library AST does not have dedicated elements for [`SoftBreak`](@ref) and [`Backslash`](@ref), and these get converted into strings (i.e. text elements) instead.
 - On Julia 1.14 and newer, [`HTMLBlock`](@ref) elements are converted into `Markdown.HTMLBlock`. On older Julia versions they are converted into `Markdown.Code("html", ...)`.
+- On Julia 1.14 and newer, [`HTMLInline`](@ref) elements are converted into `Markdown.HTMLInline`. On older Julia versions they are converted into `Markdown.Code("", ...)`.
