It's a rehash of a bunch of old misconceptions. I thought we've buried these when people got actual experience with Rust.
The dumbest one is counting changelog lines. Have you even read them? These days most of them are "obscure libstd function is now allowed in const contexts".
The regular Rust releases include compiler improvements, libstd evolution, and build system tweaks. Nobody's saying C keeps changing because LLVM has a long changelog or CMake added a new feature.
