 = 1.7.3 =
 * The visitor form is now translatable. Field labels, help text, section headings and form titles are all available to translators, so a site in German, Spanish, Hindi, Turkish, Portuguese, French or Russian can show the birth details form in that language instead of English. Translations are contributed at translate.wordpress.org and arrive automatically as language packs.
