This is the first, and hopefully only, bug fix release of the 5.7 branch of Breadcrumb NavXT. Two bugs were fixed in this release. One relating to the bcn_display_json_ld() function and the other pertaining to the injection of separators in the breadcrumb trail.
Breadcrumb NavXT 5.7.0 introduced the new bcn_display_json_ld() function. However, there was erroneous instance of $linked that caused a PHP warning. This has been resolved in Breadcrumb NavXT 5.7.1.
The second bug involved missing breadcrumb separators after removing a breadcrumb from the trail. Breadcrumb NavXT 5.7.1 uses an improved method of determining when to insert a breadcrumb separator that does not exhibit this behavior.
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.
