Programs relying on signals to terminate them should update handling of sockets to handle errors on write by exiting.
std::env::home_dirwill use the fallback if theHOMEenvironment variable is emptyextern "{abi}"s consistently in all positions. This primarily affects the use of implementing traits on anextern "{abi}"function pointer, likeextern "stdcall" fn(), on a platform that doesn't support that, like aarch64-unknown-linux-gnu. Direct usage of these unsupported ABI strings by declaring or defining functions was already rejected, so this is only a change for consistency.proc_macro_derivemacro has correct arguments when applied to the crate rootv1.89.0Compare Source
