On January 20th, the WinUI team shared a roadmap announcement that included details of releases of Project Reunion versions 0.5, 0.8, & 1.0

When will the Project Reunion roadmap be updated to include these releases?
Can these dates (& version numbers) be confirmed here?
In addition to WinUI3, what else will be in these releases?
What can we expect in terms of preview releases prior to these actual releases?
The existing roadmap document has not been updated in over 6 months and is clearly out of date.
By keeping the roadmap up to date and in sync with other teams that are part of what comes under the "Project Reunion umbrella" you provide confidence that:
I assume that you want fast adoption of the tools and functionality you release. However, if we can't know what is going to ship (and when) we have to wait until new versions ship before we know what we can use. In turn this means we can't even plan how to adopt any new functionality (let alone implement, test and release apps that use it) until your work is released.
I know slow adoption is not nice. It feels dreadful to put lots of effort into making something new only to see few people use it. Additionally, it reflects badly on the perception of the project as a whole when few people are seen to be using new features. In turn this degradation in the perception of the platform not only hurts you as the producer of the platform, but also us as people (not only developers) who work with it.
Agreed @mrlacey, we owe an update and will work on that this week. Like how many things change at Microsoft 馃榿, some of the day to day for project reunion has shifted and some of us new folks are still getting ramped up. In the meantime to your questions:
Hi @mrlacey,
Thank you for checking with us on our roadmap. We really appreciate your time here! As @tfennel said, @andrewleader and I are currently working on it this week and will use this issue to push an update to the roadmap.
Thanks again.
Dina.
Hi @mrlacey,
We wanted to get back to you to let you know that we have updated our roadmap so you can now view our latest roadmap updates here. We will continue to work on further refining our roadmap and sharing with you what we're working on and what you can expect in the future. Please let us know if you have any questions, feedback, or any improvements you would like to have.
Thank you,
Dina Ayman.
Hey @mrlacey, I just wanted to inform you that we had accidentally made a typo on our previous update to the roadmap (saying 1.0 was coming in Q3). We only noticed it now (while publishing the new updated clearer roadmap)... 1.0 had always been slated for Q4, but wanted to inform you of that typo and change in case you saw the previous roadmap and were expecting something in Q3!

Well, I mean you know how it goes with dates. We feel good about them right now though, so I'll repeat them again:
Too early to state firmly, but some examples would be potentially a Windowing preview in 0.8. Possibly a notifications preview as well. As they firm up we'll get them in the formal roadmap.
Again, plan still forming here, but likely that there won't be preview releases between 0.5 and 0.8. If we get the engineering systems working like we want at 0.8, we'll start rolling some previews of 1.0 after the 0.8 milestone.
