Yoast SEO Premium 22.6

Enhancements:

• Adds the Snippet Preview Editor to the sidebar.
• Introduces the Primary Category picker to Gutenberg.
• Introduces a loading indicator in the analysis that is shown until we’re ready to analyze the content.
• Optimizes the content analysis calculations. This fixes the issue where the UI could freeze when you have a long post.
• Changes the “Check Inlinks (OSE)” menu item in the Yoast Admin bar “Analyze this page” dropdown from the Moz OpenSite Explorer (OSE) to Google Search Console, as the former service is being disabled on August 30th 2018.

Bugfixes:

• Fixes a bug where the analysis scores would change multiple times due to a delay in the loading of the actual scores. We now show loading indicators until the actual scores have been calculated.
• Fixes a bug where the parent title snippet variable wasn’t properly being replaced with the actual parent title in Gutenberg.
• Fixes a plugin compatibility bug where the SEO score in the admin bar could not be retrieved.
• Fixes a bug where the editor would not be usable when deferred or async loading of JavaScript is being forced.
• Fixes a bug where the analysis for previously used keywords would only be triggered if the keyword was changed, resulting in an incorrect SEO score.

Enhancements:

• Revamps the design for multiple focus keywords to fit in the new metabox and Gutenberg sidebar.
• Improves the UX of multiple focus keywords. Adding and removing keywords became easier.

Bugfixes:

• Fixes a bug where the keyword analysis was not updated after changing or adding synonyms.
• Fixes a bug where the analysis icon for additional keywords would be red for an empty keyword.

Other:

• Adds the Internal Linking section to the Gutenberg sidebar.
• Adds the Insights section to the Gutenberg sidebar.
• Improved plugin performance by lazy loading the WPSEO_Redirects_Option instead of instantiating that on every request. Props to stayallive
• Includes every change in Yoast SEO core 8.0.0 see the core changelog.

Enhancements:
* Improves the link to claim your website on Pinterest by directly sending you to the right location.
* Adds the passive voice assessment for Dutch.

* Fixes a bug that caused keywords to be incorrectly recognized within possessive forms (e.g. Natalia in Natalia's fix).
* Improves the recognition of keywords with special diacritics in the URL.
* Improves keyword recognition through adding Spanish inverted exclamation and question marks to the rules that determine word boundaries.

Other:
* Corrects the WP_Filesystem() initialization call to support settings import for non-default FS_METHOD definitions.

Removes the Internal Linking meta box from the Gutenberg sidebar.
