That is certainly true, those projects are effectively dead. They lack security updates, lack integrations with new platforms, lack support for new HW architectures, lack newer privacy guarantees, etc., etc.
A db driver may have an issue with unsanitized user input when run against SQLite, but you only use it with oracle and sanitize input anyway, but that shows up as a 9.1 critical deployment blocker for corporate employees.
Unexploitable CVEs with inflated ratings make using any open source software a pain in the butt at BigCo.
Very few projects update dependencies that often, and only very big ones are found with security issues that often.
> lack integrations with new platforms
You don't need a new intration _every 2 days_, not to mention that many projects don't need such integrations at all. Moreover some popular and updated projects lack such integrations despite having lot of commits.
> lack support for new HW architectures
This is something that many projects get for free. But also, you don't get a new HW architecture every 2 days.
> lack newer privacy guarantees
What more privacy guarantees do I need from projects that don't communicate with external services or store data at all?
If it's a headers-only library in a language such as C++, if the project is not dead then the very least anyone would expect from it is being updated to support any of the modern C++ versions.
Also, if the project is actively maintained then there is always a multitude of low-priority issues and features to address.
Being FLOSS also means anyone in the whole world is able to contribute anything. If no one bothers to do so, that is aligned with the fact the project is indeed dead.
Did I miss a new C++ version released <2 days ago perhaps?
You certainly are missing something. C++26 was officially released 4 months ago, and support is slowly being rolled out to compilers and packages.

If you somehow believe this kind of work is done in a couple of days, that's a good way to explain to the world how oblivious you are about the topic you are discussing.
C++ versions are backward compatible. You don't need to modify code that works just to use recent languages features that you don't need.
As they stated, tons of 'renewed' stuff are snake oil today. They add nothing new.
