Changelog

Developers

• Identify the theme or plugin responsible for calling amp_is_request() (is_amp_endpoint()) or amp_is_available() prematurely when the _doing_it_wrong() usage notice is raised. Also identify the theme/plugin that is responsible for causing a fatal error during post-processing to display on the resulting error page. https://github.com/ampproject/amp-wp/issues/4602, https://github.com/ampproject/amp-wp/pull/5289
• Ensure amp_is_available() returns false when accessing Database Repair screen. https://github.com/ampproject/amp-wp/pull/5362
• Ensure the GitHub link to the source is formed correctly in generated documentation. https://github.com/ampproject/amp-wp/pull/5359
• Remove instances of @return annotation in hook documentation. https://github.com/ampproject/amp-wp/pull/5344

Performance

• Cache error index counts and URL count in “At a Glance” dashboard widget, eliminating the need to run additional SQL queries with each admin page load. https://github.com/ampproject/amp-wp/issues/5271, https://github.com/ampproject/amp-wp/pull/5343
• Only add_admin_menu_new_invalid_url_count when post type is show_in_menu. https://github.com/ampproject/amp-wp/pull/5336

Sanitization & Validation

• Gracefully handle sanitization of validation errors caused by use of i-amphtml-* in CSS selectors or class attributes. Instead of removing the entire style[amp-custom] or the entire class attribute, now just the invalid CSS selector or class name will be removed. https://github.com/ampproject/amp-wp/issues/771, https://github.com/ampproject/amp-wp/pull/5356
• Update AMP validator spec to 2008290323001 and improve i-amphtml-* sanitization. https://github.com/ampproject/amp-wp/pull/5356
• Validate and sanitize image candidates in srcset attributes. This prevents the sanitizer from leaking an error: “Multiple image candidates with the same width or pixel density found in attribute ‘srcset’ in tag ‘amp-img’.” https://github.com/ampproject/amp-wp/issues/5358, https://github.com/ampproject/amp-wp/pull/5366
• Gather required script components even for kept invalid markup. https://github.com/ampproject/amp-wp/pull/5388
• Prevent fatal error during post-processing from being masked by a notice. Call error_get_last() prior to calling sanitizers. https://github.com/ampproject/amp-wp/pull/5375
• Fix parsing of turn unit in CSS. https://github.com/ampproject/amp-wp/issues/4604, https://github.com/ampproject/amp-wp/pull/5392
• Update button text used in the locked post dialog when editing a validated URL post. https://github.com/ampproject/amp-wp/pull/5354

Settings Screen & Onboarding Wizard

• Avoid showing blank settings drawer for Plugin Suppression when no other suppressible plugins are active. Show message instead. https://github.com/ampproject/amp-wp/issues/5310, https://github.com/ampproject/amp-wp/pull/5349
• Fix ability to complete onboarding when Twenty Twenty is chosen as Reader Mode on a Twenty Twenty site. Override Reader mode selection and re-set page index before reaching done screen. https://github.com/ampproject/amp-wp/issues/5351, https://github.com/ampproject/amp-wp/pull/5361
• Harden presentation of available Reader themes. Ensure get_default_reader_themes returns an array and sets the array as a class attribute, and handle failed themes_api in UI. https://github.com/ampproject/amp-wp/issues/5367, https://github.com/ampproject/amp-wp/pull/5368

Reader Mode

• Prevent showing Gutenberg's new Widget Blocks section in Customizer for a Reader theme, since widgets in general are not currently supported in Reader mode. https://github.com/ampproject/amp-wp/issues/5322, https://github.com/ampproject/amp-wp/pull/5338
• Ensure robots meta tag is added to AMP legacy template when search engines are discouraged. https://github.com/ampproject/amp-wp/pull/5339
• Fix displaying relative publish date/time in legacy AMP post template when timezine is not UTC. Ensure post_publish_timestamp in AMP_Post_Template is UTC for human_time_diff(). https://github.com/ampproject/amp-wp/pull/5335

Testing

• Allow test in Test_AMP_Core_Block_Handler to run now that WordPress/gutenberg#25026 has been merged. https://github.com/ampproject/amp-wp/pull/5347
• Fix test_add_block_source_comments with latest_posts dataset when Gutenberg installed from source. https://github.com/ampproject/amp-wp/pull/5346
