Hello.
@library has gotten a new website.

Unfortunately, your bookmarks could not be transferred automatically to the new website, we have saved your bookmarks from the old website in a file that you can load on the new website.
The file can be downloaded here: @csv_url.

On the new website you can read more about how the file is imported.

Sincerely, @library.
