Perfmatters version 2.6.3

Version 2.6.3 of our Perfmatters WordPress plugin was released on May 27, 2026.

Changelog summary

  • Added new Shortcode option when choosing a location for HTML code snippets.
  • Added new code option to select the Editor Theme along with the ability to upload a custom CodeMirror 5 theme stylesheet.
  • Added base64 encoding to exported code snippets to prevent import requests from being blocked by certain firewalls. Previously exported code snippet JSON files can still be imported.
  • Added new Location helper class to store shared logic to parse and match string based location input fields throughout the plugin.
  • Added the ability to use the ‘front’ keyword in location input fields to always match the front page of the site.
  • Added additional lazy loading compatibility styles specifically for iframes placed inside Elementor text and HTML elements.
  • Adjusted Script Manager Global View rows to always display multiple post IDs in ascending order.
  • Multiple styling adjustments and fixes throughout the plugin UI.
  • Made some changes to how certain UI elements trigger a forced reload in response to specific actions to make things less jarring.
  • Fixed an issue where our compatibility styles for a lazy loaded video inside a responsive embed could break the layout if the core block library stylesheet was disabled.
  • Fixed an issue where code type selection for individual code snippets was still visible even after saving.
  • Fixed an issue where the next page buttons in the snippets table was still showing as active even when viewing the last page.
  • Fixed an issue where stylesheets with protocol-relative URLs were not getting parsed for used CSS.
  • Disabled lint markers for HTML code snippets, as they do not currently work for combined HTML and inline PHP code.
  • Removed unnecessary instances of perfmatters-lazy-youtube class from lazy loading inline styles. All lazy loading video features are now using a shared perfmatters-lazy-video class.
  • Removed unnecessary development directories from plugin files.
  • Translation updates.
