Holy REST API Batman! New in this release is the addition of REST API endpoints for posts (of any post type), terms (of any taxonomy), and author archives. Support for root pages for author archives was also added. Additionally, support for microdata format Schema.org BreadcrumbList was added to the included widget.
On the bug fix front, two bugs were fixed in this version. One bug involved a PHP warning being thrown due to get_term() not returning an instance of WP_Term. The other involved fixing the incorrect label for the Schema.org BreadcrumbList RDFa format option.
REST API
The Breadcrumb NavXT REST API introduces endpoints for retrieving Schema.org BreadcrumbList compliant JSON-LD formatted breadcrumb trails for posts, terms, and author archives. For applications that do not need the REST API, it may be disabled by defining BCN_DISABLE_REST_API to be false in wp-config.php. See the Breadcrumb NavXT Rest API Reference for more information.
Regarding Support
Previously, support for Breadcrumb NavXT was provided on this site and the WordPress.org sub-forum for Breadcrumb NavXT. Breadcrumb NavXT even included a link to the release announcement for reporting bugs. However, starting with 6.1.0, official support is moving completely over to the WordPress.org sub-forum for Breadcrumb NavXT. Most support queries already come through the forums, this just codifies it. Users of the premium extensions with valid support license keys still receive email support initiated via the support ticket form.
As always, you can grab the latest version of Breadcrumb NavXT from the Breadcrumb NavXT page. If you experience any issues with this version of Breadcrumb NavXT, please leave a comment on this post detailing the issue.
