Compatibility Notes
TypeId
.Code that uses a constant
TypeId
in a pattern will potentially be broken.Known cases have already been fixed -- in particular, users of the
log

kv_unstable
feature should update tolog v0.4.18
or later.sysroot
crate to represent the standard library crates.This does not affect stable users, but may require adjustment in tools that build their own standard library.
rustup
. WhenCargo detects it will run
rustc
pointing to a rustup proxy, it'll try bypassing the proxy anduse the underlying binary directly. There are assumptions around the interaction with rustup and
RUSTUP_TOOLCHAIN
. However, it's not expected to affect normal users.handle misspellings. Previously, Cargo tried each
combination of hyphens and underscores, causing excessive requests to crates.io.
RUSTUP_HOME
andRUSTUP_TOOLCHAIN
in the[env]
configurationtable. This is considered to be not a use case Cargo would like to support, since it will likely
cause problems or lead to confusion.
Internal Changes
These changes do not affect any public interfaces of Rust, but they represent
significant improvements to the performance or internals of rustc and related
tools.
