Compatibility Notes
rustc
no longer treats thetest
cfg as a well known check-cfg, instead it is up to the build systems and users of--check-cfg
[^check-cfg] to set it as a well known cfg using--check-cfg=cfg(test)
.This is done to enable build systems like Cargo to set it conditionally, as not all source files are suitable for unit tests.
Cargo (for now) unconditionally sets the
test
cfg as a well known cfg.[^check-cfg]: https://doc.rust-lang.org/nightly/rustc/check-cfg.html
Disable potentially incorrect type inference if there are trivial and non-trivial where-clauses
std::env::home_dir()
has been deprecated for years, because it can give surprising results in some Windows configurations if theHOME
environment variable is set (which is not the normal configuration on Windows). We had previously avoided changing its behavior, out of concern for compatibility with code depending on this non-standard configuration. Given how long this function has been deprecated, we're now fixing its behavior as a bugfix. A subsequent release will remove the deprecation for this function.Make

or vice versa on many Tier 2 and 3targets (mostly Arm and RISC-V embedded targets). The new definition may
result in compilation failures but fixes compatibility issues with C.
