 -   TypeDoc now has the architecture in place to support localization. No languages besides English

 -   `--hostedBaseUrl` will now be used to generate a `<link rel="canonical">` element in the project root page, #2550.
+-   New option, `--customFooterHtml` to add custom HTML to the generated page footer, #2559.
 -   Added three new sort strategies `documents-first`, `documents-last`, and `alphabetical-ignoring-documents` to order markdown documents.
 -   Added new `--alwaysCreateEntryPointModule` option. When set, TypeDoc will always create a `Module` for entry points, even if only one is provided.
     If `--projectDocuments` is used to add documents, this option defaults to `true`, otherwise, defaults to `false`.
