This change introduces the formal specification and documentation for the experimental \amp-iframe\ version 1.0, marking it as a Bento-supported component. The new \validator-amp-iframe.protoascii\ file defines the validation rules for the 1.0 version, including supported attributes like \allow\, \referrerpolicy\, and \tabindex\, while keeping the legacy 0.1 version as deprecated. Accompanying documentation (\amp-iframe.md\ and \amp-iframe-vs-native-iframe.md\) explains the component's usage, security restrictions, dynamic resizing capabilities, and why it remains necessary compared to native iframes for features like consent data handling and cross-browser lazy loading. An \OWNERS\ file is also added to assign maintenance to the \ampproject/wg-components\ working group.

This change introduces the foundational documentation, ownership, and validation rules for the amp-instagram extension. It adds an OWNERS file defining the responsible working groups, a markdown specification detailing the component's behavior (including automatic handling of Instagram's 'chrome' spacing around images) and attributes like data-shortcode and data-captioned, and a validator protoascii file that defines the amp-instagram 1.0 specification alongside the legacy 0.1 version, ensuring proper validation of the embed element's attributes and layout support.

The \amp-lightbox-gallery\ extension now integrates with the AMP history service to manage browser back-button behavior, pushing a history entry when the lightbox opens and popping it when closed. Additionally, the component now triggers analytics events for key user interactions, specifically firing 'lightboxOpened' when the gallery opens, 'thumbnailsViewToggled' when the thumbnail grid is viewed, and 'descriptionOverflowToggled' when captions are toggled.

The amp-selector extension introduces version 1.0, establishing a new validation schema that supports the \keyboard-select-mode\ attribute for improved accessibility and allows binding to the \disabled\ state. This release also includes comprehensive documentation covering usage, events (including \event.selectedOptions\), and the \clear\ action, alongside updated OWNERS configuration to reflect current working group responsibilities.

The amp-sidebar extension has been updated to version 1.0, introducing support for the autoscroll attribute to automatically scroll to elements marked with autoscroll within the sidebar or toolbar, and enabling toolbar functionality that allows navigation elements to be duplicated and displayed in other parts of the page via media queries. The validator rules now explicitly define the 1.0 version alongside the deprecated 0.1 version, and the documentation has been refreshed to cover these new features, including usage in AMP4Email and amp-story contexts.

The amp-twitter component has been significantly refactored to use a new loader implementation and improved resource loading strategies. The JavaScript source now utilizes core DOM helpers and a new 3p-frame messaging system, replacing older patterns. A key behavioral change is the introduction of explicit preconnect and preload logic for Twitter domains (platform.twitter.com, syndication.twitter.com, pbs.twimg.com) to speed up embed rendering. The component now handles loading, success, and failure states more robustly, supporting placeholders and fallbacks as documented in the newly added amp-twitter.md specification file. The API surface remains compatible, requiring data-tweetid or data-momentid attributes.

The amp-youtube component has been significantly refactored to extend AMP.BaseElement instead of the legacy AMP.AmpElement, adopting modern AMP infrastructure such as the PauseHelper for viewport-based playback management and the VideoManager for standardized video events. This change introduces privacy-enhanced mode support via the credentials attribute (which appends -nocookie to the embed URL when set to 'omit'), improves autoplay handling by managing mute/unmute states internally rather than relying on YouTube's autoplay parameter, and adds support for live channel embedding via the data-live-channelid attribute. The component now also supports the dock attribute for video docking when amp-video-docking is present, and uses data-param-\* attributes to pass custom query parameters to the YouTube iframe while excluding autoplay and loop which are handled by AMP.
