Is Higher Logic terminating open source Vanilla?

open.vanillaforums.com has a March 1, 2025 post from @Linc, an Admin, titled Higher Logic has terminated open source Vanilla.
@Linc says:
On 2 Dec 2024, I received this message from Higher Logic's Director of Software Engineering:
". . . we have decided to deprecate continued support for the open source version of Vanilla Forums."
@Linc also says:
Higher Logic removed the Addon directory without notice.
I therefore strongly recommend migrating to another forum software, like Flarum, immediately. Your forum will eventually become compromised without ongoing security updates.
However, further down, @mcrouse, also an Admin, replied on March 6, 2025:
At present, Higher Logic has not discontinued support for the Open Source version of Vanilla. However, our recent upgrade to PHP version 8.1+ has posed significant challenges with legacy code relied upon by the Open Source version, impacting our ability to maintain add-ons and push additional update to the solution this year.
What's going on over at Vanilla? What effect will there be here at LES?
I hope everyone gets the servers they want!
Comments
Nothing for LES atm I am watching and if push comes to shove will act. Right now there are no flaws and if it becomes that there is I am sure something can be done to remedy the situation.

For immediate release
I can neither confirm or deny that @AuroraZero is the real owner of LES.
It sounds like the github repo will stay open to community contributions so it's likely that there will at least be security fixes as needed. One of the things I like about this software is its relative simplicity, so it's fine with me if not too many new features get added going forward.
Fork and make “Vanilla Ice Cream” version. Flarum is not acceptable as alternative.
Looks like there was a release yesterday,

It seems like a login might be needed to read the release notes at success.vanillaforums.com.
I ran
git clone https://github.com/vanilla/vanilla.git
. After taking a quick look around, I didn't find the release notes.Maybe I might try setting up Vanilla. . . .
I hope everyone gets the servers they want!
The end is nigh.
LES forum deadpools.
IRC channel remains.
No hostname left!
or we clone raidforums and disguise ourselves as a hacking forum!
or we set up whmcs and all the tickets are just threads

Here is a quick overview of what might be the current Vanilla OSS HEAD ecosystem surrounding the above cloned Vanilla repository.
Does it seem like a clueless™ guy could install Vanilla and actually get it working without too much trouble?
Is there an easier or better way to look at software similar to what LES is running?
Does anybody else want to participate?
Vanilla-Docker
Besides the Vanilla repository that I cloned, the main Vanilla Git Repository also offers a Docker environment version, which says,
Vanilla OSS Head (just after 2025.003)
From README.md in the cloned git repository:
Installation
The current version of Vanilla requires PHP 7.2+ and MySQL 5.7+. The following PHP extensions are also required: cURL, DOM, Fileinfo, GD, intl, JSON, libxml, PDO

How can we understand a little about how LES works?
I took a quick look at Advanced PHP localhost development on a Mac for mere mortals (2021?), written by the guy who seems to be @linc on the open.vanillaforums.com website. From this I got the idea also to also try a version of Wordpress, since Wordpress and Vanilla both use php.
From the post:
Also found, Vanilla 2023.001 Open Source Release - PHP 8 Works! (Built From Source) — Vanilla Forums. It looks like there might be a chance that this week's Vanilla OSS HEAD might at least partly work with PHP's latest software?
We have a 2021 post here at LES which says LES runs on PHP 5.6 and LiteSpeed. Is that still true?
So . . . maybe, on a Linux server, I could just try grabbing and building current or very recent sources for Apache, MariaDB, and PHP plus Vanilla OSS HEAD plus WordPress or maybe ClassicPress -- see also Classic Press Github. Here also is a link to sources for OpenLiteSpeed just in case it's decided to go with a server possibly closer to LES than Apache.
There is no plan to run an actual site. So it doesn't matter at all if this little project doesn't get fully completed or doesn't even work. The fun parts are looking at the source code, building, and installing.
Anybody interested joining this project to maybe understand a little about how LES might work?
Anybody have hints on mistakes that I am making here? 
Thanks everybody!

No surprise, really. They've been planning this for long, and I have known it for more than 2 years.
Early in 2023, I was looking for a download of vanilla package from their site but it kept redirecting me to higherlogic.com. so, the next step was to look up in the web archives. Here's the last archive of domain actually opening the corrent site.
https://web.archive.org/web/20221214112128/https://vanillaforums.com/
Here, you had a link at the bottom called Open Source that led you to the Vanilla Forums download page:
https://web.archive.org/web/20221219224515/https://vanillaforums.com/software/
But, since the domain was redirected to https://vanilla.higherlogic.com/, this link and page went missing. The past download link leads you to a "Page Not Found The page you were looking for could not be found." message.
There are threads at https://open.vanillaforums.com/ since 2023 about moving from Vanilla to Flarum or other alternatives.
I had lots of fun this evening downloading the sources for Apache, skimming the install documentation, and glancing at some of the source code!
Maybe I could post about compiling and running self-compiled Apache, possibly followed by additional posts about MariaDB, PHP, Vanilla, and Word/ClassicPress?
On the other hand, perhaps (hopefully) compiling a LAMP stack and perhaps (hopefully) getting Vanilla running on it is too off topic (even though LES runs on Vanilla)?
What do you think? Thanks!
I hope everyone gets the servers they want!
If you need something small coded, such as a fix for something, let me know and I shall provide.
Took a stab at diagramming the LES "Stack". This should cover most of what's under the hood. On the eventual to-do list is upgrading Vanilla to a more recent version as well as upgrading PHP (which is still using 7.4 at the moment, but I've tested 8.2 in Dev before and got it functional so I know it's relatively easy).
Vanilla OSS has been losing support from Higher Logic for a long time now. We've been on an old version for years now and I've tested upgrading the forum a couple times on the dev site with mixed results and poor documentation my first couple go-arounds. I'll take the plunge and complete the upgrade at some point in the near-ish future after working out all the issues first. Seems like the community will maintain the OSS version without Higher Logic's "official" support. I doubt there will be any huge updates or feature additions moving forward, but that's not a big concern to me.

Hey @Mason!
Thanks for carefully and completely answering my question with your terrific chart!
Maybe, going forward, the chart could live in the What the FAQ?! thread?
Thanks for everything you do for LES!

I grabbed a CPX-11 (same as what LES ifs using), posted a yabs, and tried a couple of new installs (not upgrades) from the https://github.com/vanilla/vanilla repository.
Both the
git clone
and the OSS Release 2025.003 file archive seem to leave me with the following error when I visit with my web browser: "Could not find the autoloader. Did you forget to run 'composer install' in '/var/www/redacted.xxx' ?"What I had been expecting to see was an admin account creation dialog box for Vanilla. Something like the image shown on this ancient tutorial.
The first time I tried to download and run composer I got errors. Several errors were because of PHP packages that apparently should have been but were not installed with apt. I wiped everything, went through the install again, with the missing apt packages added.
Now I want to read some of the composer documentation before I try running composer again.
I haven't yet found any tutorial on installing OSS Vanilla 2025.003. I haven't been able to access the release notes mentioned on https://github.com/vanilla/vanilla/releases/tag/2025.003 as being available at https://success.vanillaforums.com/kb/articles/1754-release-2025-003. I just get a file not found, and I can't seem to make an account to log in.
It would be nice to write a tutorial on installing OSS Vanilla 2025.003 if I get it installed.
Just to be clear, I'm not planning to start another forum which competes with us LESbians.
Thanks @Mason!
Thanks everyone! 
I hope everyone gets the servers they want!
