[APL 1.6] Echo Show 8 is now a Hub Landscape Medium device. Customer feedback on the Echo Show 8 indicated that the font size was too small on many Alexa experiences. To address this, we've updated how the device reports it's screen size, which results in the device being classified as a Hub Landscape Medium device instead of a Hub Landscape Large. To account for this change, we recommend you review the Interfaces page in the Alexa developer console and ensure you have Hub Landscape Medium checked, as well as all the boxes for any other viewports that you support. Existing skills will not be impacted. They will continue to see Echo Show 8 as a Hub Landscape Large device until they check the box to opt in to Hub Landscape Medium as a supported viewport profile.
[APL 1.6] On FireTV directional keys no longer cause Pagers to animate in APL documents with version <1.6. To mitigate, change the APL document version to 1.6.
[APL 1.6] On an Alexa-enabled device with a screen, the viewport is the area of the screen that the user can see. A viewport has a shape, orientation, size, and density. In that, size and density are defined as ranges so that the profile can represent multiple physical devices. When you manually provide fixed/legacy viewport dimension values instead of the currently supported viewport ranges in the skill manifest for Hub Round Small, Hub Landscape Small, Hub Landscape Medium, and Hub Landscape Large devices, the corresponding viewport profile checkboxes aren't checked in the developer console. The current best practice is to verify whether your APL content renders correctly on the required viewport profiles, and then select the corresponding viewport profiles in the console or provide the corresponding supported viewport ranges manually in the skill manifest.
