Analyzer said: As many of you recall, we were testing some enhancements on the dev server . These changes are now fully live for everyone to use! You can find information on our Help Center regarding more specifics of this update Below is the familiar list of changes that were implemented: A new, less restrictive HTML sanitization system, which now allows for: Accessibility enhancements: ARIA and semantic HTML support No pre-pending of “sheet-” to classes Unique identifiers (id=””) in HTML elements Allowing the usage of HTML datalists Allowing the usage of HTML details and summary tags The CSS sanitizer has been removed, which now allows for: Media queries that allow responsive design Sheet authors can now use the print media query to style their character sheet for printing from the popout window Support for CSS Animations Integrated macro bar for character quick attacks, including pop out windows Below are the FAQs from last time that we believe are still relevant: Do I have to change anything on my sheet? Nope! The new system will be the default going forward, but you will still be able to opt-in to the legacy system. All existing sheets, including games with custom sheets, will be automatically opted-in to the legacy system. At some point, we may remove the legacy sanitization, however an announcement will come well in advance to prepare you for legacy retirement. For sheets submitted to our sheet dropdown or used via our sheet sandbox system, the opt-in for legacy sanitization can be toggled through a boolean value (true/false) in the “legacy” field of your sheet.json. For custom sheets, there is a legacy sanitization checkbox you can toggle in your game settings page above the “Custom Sheet” section. Note Regarding Roll Templates Because chat is closely integrated into the VTT, roll templates will continue to use the legacy system, both for CSS and HTML. What kinds of things should I be looking out for? This is a pretty fundamental change to how character sheets work, as almost all character sheet functionality has been touched to some degree or another. We've been testing this internally for a while, but with 800+ character sheets, we can't check them all ourselves. One of our main concerns is that existing sheets continue to work exactly as they did before, and we would love the community's help in verifying their sheets. Again, we’d like more testing done on existing sheets (using the legacy system). As you test, things to pay attention to on both systems are: Drag and drop functionality and performance Missing and/or incorrect HTML + CSS in your character sheet Sheetworkers functioning as expected Issues with your roll templates We’re also inviting sheet authors to start playing around with the new sanitization system in custom sheets. We’re excited to see what you can do, so let us know in the thread what awesome and cool things you can do with these changes! Please feel free to share your feedback and ask questions! So my Character sheets have stopped working again...
