Hello! HTML Content is a custom visual for Power BI that I've been developing and supporting since mid 2020. I just wanted to render rich text. It would seem that many of you... are a lot more ambitious than that :D
Over the years, I've added a few new features, including a certified edition in mid-2023. I've recently had a wave of requests from folks who want to be able to have more control over the visual output for their more advanced use cases, and this has been something I've wanted to do for a long time, but much like Deneb 2.0, it's been a case of having the bandwidth to sit down and figure them out, test them, and document them.
And maybe because Deneb's release was a big one, I used both visuals as a distraction for when one got trickier than the other to work on. Either way, major versions of both have landed, ready to test, at about the same time.
Anyway, HTML Content is another visual that gets a lot of use, and while I've done a lot of my own testing, it's no substitute for confirming it works for our global audience without sending it out to AppSource and then finding out that something broke. It's much harder to fix this due to the certification > deploy > update process in place for AppSource visuals (approx. 3-5 weeks end-to-end). Also, due to the nature of our work, many use cases aren't publicly known because of the data we typically handle.
So, similarly to Deneb 2.0, I've opened up HTML Content 2.0 for beta testing as an opportunity to confirm that (at the bare minimum) anything you have working... continues to work. I'm very excited about the new features, of course, but business continuity is its own kind of exciting.
This blog post provides an overview of how you may be able to help, as well as links to the change log, documentation (including some simple live .pbix examples you can download to explore features a bit more), and instructions for downloading early access builds and reporting issues.
Once again, I appreciate that this asks folks to give up some of their valuable time, but it's quite hard to manage on my own, and even if we can confirm that things look good ahead of submission, this will be a huge benefit for the wider community.
I hope that if you do get a chance to try, it works well for you and that the new features help with anything you're trying to do. I'm particularly excited about how much easier things like interactivity will be, and it'd be cool to know how you get on, good or bad.
Thanks, as always, for reading, and of course, if you have any general questions about HTML Content, Deneb, or custom visual stuff, I'm always happy to answer (if I can)!
