As @PulkoMandy has pointed out in his latest Activity Report for January, this year marks the 20th year of the Haiku Project.
For community projects, 20 years is a significant milestone - Wikipedia just celebrated their 20th year with some celebrations as well as a celebration subsite.
So for the 20th year of Haiku, we want to hear what ideas you have as to how we can celebrate - give us all your suggestions!
Fireworks in the About Haiku window?
Give us R1 
Whilst I’m pretty sure that would be a great thing to happen, it’s not very realistic.
If you take a look at our Roadmap on Trac: https://dev.haiku-os.org/roadmap, it looks like we are nearly there, but in reality there are 685 tickets still open - for perspective, Beta 3 has 187 tickets. That means it would take around 3 more releases similar in size to Beta 3, and a much smaller release to close everything off. That means if there are no delays, there should be:
@PulkoMandy mentioned that the dev team is aiming for a yearly Beta release, which means R1 has an estimated release date of 2025. Now, this is if things don’t change and the developer team stays the same as it is now, and even then, this timeline is quite optimistic.
It should prolly be stated that it is extremely difficult to close (with good justifications) 90-95 percent (let alone all) of the bug reports and tickets, even if new submissions are temporarily frozen. That goes for most kinds of software, let alone entire operating systems. Doesn’t help that manpower is still somewhat lacking for a project of Haiku’s scope. Expecting R1 within this year or within the next 2-3 years is unrealistic, barring perhaps a large influx of new contributors.
Despite all this, the work achieved so far and for so long by such a small group of folks is still very much commendable.
Not a suggestion, but here are some screenshots from early OBOS 
Not Haiku, but where we all came from: BeOS in it’s best days
I just hope the worldwide situation gets better and we can have a real life meetup sometime later this year to celebrate.
But if you are looking for things to start preparing now, contacting and interviewing past contributors to haiku and seewhat they remember of the early days and what thoy are doing today could be an interesting thing to do
This kind of sounds worse than what I hoped for, but I am happy that after 20 years project exists and advances. Everyone who was taking part deserves more than a piece of cake for sure
I think this kind of roadmap and release cycles might put some people off from contributing, but this is why BeOS>OpenBeOS>Haiku history and community needs to be documented in a popular way so people can get a feeling for it (beyond harsh metrics).
Maybe a media-rich wiki project would be nice to have so everyone can contribute, work in parallel and also show different levels of complexity in such project and community. I would commit to both brainstorm, co-develop and contribute to such thing (anyway busy with wikis and media). I used to do this on BeBits wiki (which I kind of asked for and loved :-)…
Is there any wiki in use these days for any purpose similar?
Maybe you could join the promotion team for this?
If @jt15s thinks this kind of project would be something the team wants to work on I would not mind, but I would not be as free to work on other activities beyond consulting here and there.
Somewhere around is haiku’s first baby picture- when it was just a command prompt, but it booted. That would be nice to include.
I have it if I can find it…
My oldest one are from 2007
Is it old? Hold my beer!

Wait, Firefox on Haiku was a thing back in 2006?
it’s native FireFox (Semonkey, Thunderbird and Nvu) for BeOS.
01.06.2006 Nvu
Yes, we have a Firefox 2, it was renamed to BeZilla because Mozilla protects their trademarks and it was not an official version. Then they started rewriting a lot of things in Firefox 3 and we couldn’t keep up with the changes.
Oh, so that’s what BeZilla is! I thought it was something like FileZilla.
