l10n settings

This version introduces improvements to string translation for field and field group settings. Previously, each field’s label and instructions were passed through the WP __() function for basic translation. Without the ability to specify what was translated and by what textdomain, this caused various issues among international users.

To solve this issue, string translation settings have been added for customization. Now, ACF will not translation any field of field group strings unless a textdomain is set. Please find the new settings below.

l10n boolean Allows ACF to translate field and field group settings using the __() function. Defaults to true. Useful to override translation without modifying the textdomain
l10n_textdomain string Sets the text domain used when translating field and field group settings. Defaults to ”. Strings will not be translated if this setting is empty
l10n_field array An array of settings to translate when loading and exporting a field. Defaults to array('label', 'instructions')
l10n_field_group array An array of settings to translate when loading and exporting a field group. Defaults to array('title')
