An early commit for WordPress 5.5 (which isn’t even in beta, don’t get scared) is a long awaited update to SimplePie! That’s right #36669 has finally gone through.
The library has been updated in WordPress trunk from version 1.3.1 to version 1.5.5. Trunk always contains the bleeding edge, unreleased WordPress code that is being worked on for the next release. When you have a chance, please take the time to test your plugin on trunk to ensure you do not experience any issues or unintended behavior after this update.
Here are some resources that may help you:
- A full list of changes in the library: https://github.com/simplepie/simplepie/blob/master/CHANGELOG.md
- The changeset updating SimplePie in WordPress: https://core.trac.wordpress.org/changeset/47733
Later, we will be emailing people whom we feel would be directly impacted by this change, but for now if your plugin uses RSS feeds in any way, or directly integrates with SimplePie, we ask you take the time to check if everything is still working.
