Changelog for WP SEO 1.2

If you want to help test, you can download the development version from here, or directly from here. If you find issues, please file them here.

= 1.2 (development version) =

Major improvements: all sorts of fixes to suggest and keyword check functionality which now should allow for non-ascii stuff, like Greek, Arabic, but even "weird" chars in western-European languages.

  • Bugs fixed:
    • ereg_replace != preg_replace ; in other words: alt and title tags for images in xml sitemap fixed.
    • Image size for OpenGraph now defaults to medium for thumbnail image.
    • Selecting a Facebook App as the admin of your site now actually works.

What to do with SVG's

Regex search:

  • style=(["|'])fill:#([a-zA-Z0-9]{3,});\1 replace with fill="#$2"
  • (class|id)=(["|'])([a-zA-Z_0-9-^-]+)\2 replace with blank

In a nuttshell:

  • Remove <title> and <decoration> if the image is “just decoration”.
  • Add role="img" aria-hidden="true" focusable="false" to the svg. Exclude aria-hidden="true" if its an infographic.
  • If its important to understand the “svg” in order to understand what the page is about, use aria-labelledby="title desc" on the SVG and use <title> and <desc> element in the SVG.
