What’s changed in 3.9.7?

You’ll find a full changelog at the end, but here are the main changes.

PHP 8 compatible

We tested this release with PHP 8 and removed code that was deprecated.

JSON-LD aware

JSON-LD, or JavaScript Object Notation for Linked Data, is used by publishers to embed machine-readable data about articles on their websites. It’s become common practice in recent years.

We’ve noticed cases where the data that Full-Text RSS previously looked to extract from meta tags or HTML elements inside the body are, on some sites, only found inside JSON-LD objects. As such, we’ve added code to our content extractor in this version to look inside these objects for the article title, author and date.

Automatic site config updates fixed

Automatic site config updates through the Full-Text RSS admin pages stopped working recently. We rely on Github for these and the HTTP headers we looked for had changed, so we’ve now updated our code to handle it.

SubToMe.com offers a convenient way to subscribe to a feed in your favourite feed reader. In previous versions we used it in the feed preview and in a <atom:link rel="related"...> field in the feed output. Unfortunately it hasn’t been updated since 2015, so some of its subscribe endpoints (e.g. Feedly’s) are no longer valid.

We now point users to our own subscribe page. Here’s an example: https://subscribe.fivefilters.org/?name=FiveFilters.org&url=https%3A%2F%2Fblog.fivefilters.org%2Ffeed.xml

Note: this is currently hardcoded to use subscribe.fivefilters.org, we plan to offer this as part of the Full-Text RSS package in the future.
