Let me rephrase this into more human language:
"As we have access to server logs we can see clearly that servers are being overloaded by query spam that includes requests for most expensive stuff only. The requests are neither premeditated nor followed by other requests which are typical to human ...

From what I can tell, it's not really AI scrapers (this time) but a targeted attack on phpBB since they specifically request expensive endpoints and abuse phpBB's flawed handling of anonymous sessions. And if you've never seen a DDOS before, I can share with you how it looks on the graphs.

Disabling search for guests was intentional, and unfortunately "active topics" is considered search in phpBB despite being a simpler query. As the DDOS situation is stabilized we will probably re-enable it.

I was able to rebase the release build environment atop Ubuntu 22.04, so the next release should require glibc 2.35 instead of 2.36.

Thanks for the report, for the state of the repo this was fixed manually, and for future releases this should be handled correctly.

The mod portal parses the info.json and stores the contents in a document store - it needs to be queried like any other data. The escaped strings could be fixed for displaying, the key ordering probably won't be.

Have you considered statically linking musl, instead of dynamically linking glibc?

This would allow the same builds to run regardless of the system glibc version, and would also run on musl-based distributions natively.


We have considered it, it's just a little low priority, and we are using ...

As a part of the update of our graphics and audio systems, we have raised the minimum operating system requirement on Linux. The minimum version of the system's GLIBC is now 2.36 (released in 2022). If Factorio doesn't launch on your system, you may need to update. Headless and Steam versions are ...

Why wasn't the character limit on the forums mentioned? You obviously seemed to have a problem with posting the changelog here, as you wouldn't have had to split it into one long post and an even longer post otherwise.

The forums are linear, so there's no problem with splitting the post since ...

We have enabled Linux Runtime 4.0 on Steam for versions 2.1.x, hopefully that will work for most players. Still looking into lowering the glibc requirement for the standalone version!

Good news, I don't yet know if it's the root cause of this perf regression, but I did manage to fix LTO for Linux builds by downgrading mold (the linker we use). It'll go out with the next release.

I was so confused by this until I tried it myself. By Waypipe, I'm guessing you meant Pipewire? Because that was the first no-go I ran into trying it on Debian 11. But uhh... just throwing it out there... Ubuntu 22.04 has all the required SDL3 dependency package versions and a lower glibc >.> If ...

Thanks, this should be fixed

The trick is: the build servers run Debian 13, but compilation is done inside a Debian 12 Podman container ;)

Our builds are now based on Debian 13, which uses glibc 2.41. We need Debian 13 for various reasons related to platform integration.

Side note: the headless version is built on Debian 11 instead and should run in many more cases.

In fact, with the exception of headless, we are currently ...

2.1.7 for Linux was compiled without LTO (link-time optimizations) due to a last minute issue cropping up when linking against the Steam dynamic library (.so). This large of a loss in performance is unexpected (LTO is supposed to account for ~2-3%) but it may be related nevertheless -- we'll try our ...

Is there any reason that this version has been removed from Steam?

Unfortunately, Steam only allows us to offer 25 branches at a time. So as we add new versions we are forced to remove old versions. We try to keep one stable version per old major version and then it's based on usage, but for ...

This is acceptable, just don't overload the server and follow the license (CC BY-NC-SA). :)

And? This is not a reason to stop working things that worked flawlessly.


It's not like we (Wube) changed something to break Windows 7 on purpose. In this case our server provider is responsible for maintaining industry standard security. Meanwhile we rely on the operating system to give us ...

It's a great shame. She will be remembered and missed.
