Yoast SEO was updated to version 7.4.2, from version 7.3. Changelog:
- Fixes automatic image size detection for OpenGraph images. When an image was used that was too large, we wouldn’t output the og:image tag. That is now fixed.
- Fixes a bug where portrait images where not allowed for the OpenGraph image.
- Re-adds wpseo_opengraph_image_size filter. This will completely override any automatic size determination our code does. This filter now also applies to all ways an og:image can be determined: In the content, as a featured image or as set in our Facebook image setting.
- Fixes an unintended backwards incompatible change which caused “Warning: Illegal string offset ‘url’ in”.
- Fixes an unintended change which caused SVGs to be included in consideration for the og:image tag. SVG images are not allowed by Facebook, so these should never be used in the og:image tag.
- Adds OpenGraph image dimension-meta tags for more images.
- Excludes images from being used in OpenGraph meta tags, if the image is larger than 2MB.
- Adds caching for images found in a post to reduce load.
- Adds image alt tag to the OpenGraph output, using the meta tag og:image:alt.
- Adds the is_post_type_viewable WordPress function to improve support for the wpseo_accessible_post_types filters.
- Fixes a bug where a non-array value causes a fatal error when cron_schedules filter has been executed.
- Fixes a bug where not all database tables were removed when a subsite was deleted in a multisite environment.
- Fixes a bug where deleting multiple posts might cause performance issues.
- Introduces a message, warning about dropping of PHP 5.2 support in an upcoming version.
- Alters the configuration service text in the Configuration Wizard when a user is already running Yoast SEO Premium. Previously the text contained a reference to getting a bundled copy of Premium, even if the user was already running Premium.
