Thanks! That would resolve the naming concern.

Should we make any arrangements for a transition period, like keep the old target around for a bit? (Not sure if we have a way to mark a target as "deprecated".)

Should we make any arrangements for a transition period, like keep the old target around for a bit? (Not sure if we have a way to mark a target as "deprecated".)

No dedicated infrastructure (yet). The closest approach I know of is the wasm32-wasip1 naming transition rust-lang/compiler-team#695, but that required careful manual transition implementation (ship alias, warning, blog posts, etc.).

One reason to keep the old target for a bit would be so that people can use the same config for stable and nightly, but given that this is tier 3 I expect everyone to use nightly anyways so just doing it directly seems fine.
@jackpot51 you can decide if you want to keep the old target around a bit or just have the old one.

I wouldn't bother with any warnings for this.

There's no fundamental reason to keep the old target around. Redox OS upstream builds use a pinned nightly version, so we simply won't update it until the necessary changes here have been adapted to.

rust186: add a package for rust 1.86.0.
3b2d187 
Upstream changes relative to 1.85.1:

Version 1.86.0 (2025-04-03)
==========================

Language
--------
- [Stabilize upcasting trait objects to supertraits.]
  (rust-lang/rust#134367)
- [Allow safe functions to be marked with the `#[target_feature]` attribute.]
  (rust-lang/rust#134090)
- [The `missing_abi` lint now warns-by-default.]
  (rust-lang/rust#132397)
- Rust now lints about double negations, to catch cases that might
  have intended to be a prefix decrement operator (`--x`) as written
  in other languages. This was previously a clippy lint,
  `clippy::double_neg`, and is [now available directly in Rust as
  `double_negations`.]
  (rust-lang/rust#126604)
- [More pointers are now detected as definitely not-null based on
  their alignment in const eval.]
  (rust-lang/rust#133700)
- [Empty `repr()` attribute applied to invalid items are now
  correctly rejected.]
  (rust-lang/rust#133925)
- [Inner attributes `#![test]` and `#![rustfmt::skip]` are no longer
  accepted in more places than intended.]
  (rust-lang/rust#134276)

Compiler
--------
- [Debug-assert that raw pointers are non-null on access.]
  (rust-lang/rust#134424)
- [Change `-O` to mean `-C opt-level=3` instead of `-C opt-level=2`
  to match Cargo's defaults.]
  (rust-lang/rust#135439)
- [Fix emission of `overflowing_literals` under certain macro environments.]
  (rust-lang/rust#136393)

Platform Support
----------------
- [Replace `i686-unknown-redox` target with `i586-unknown-redox`.]
  (rust-lang/rust#136698)
- [Increase baseline CPU of `i686-unknown-hurd-gnu` to Pentium 4.]
  (rust-lang/rust#136700)
- New tier 3 targets:
  - [`{aarch64-unknown,x86_64-pc}-nto-qnx710_iosock`]
    (rust-lang/rust#133631).
    For supporting Neutrino QNX 7.1 with `io-socket` network stack.
  - [`{aarch64-unknown,x86_64-pc}-nto-qnx800`]
    (rust-lang/rust#133631).
    For supporting Neutrino QNX 8.0 (`no_std`-only).
  - [`{x86_64,i686}-win7-windows-gnu`]
    (rust-lang/rust#134609).
    Intended for backwards compatibility with Windows 7.
    `{x86_64,i686}-win7-windows-msvc` are the Windows MSVC counterparts
    that already exist as Tier 3 targets.
  - [`amdgcn-amd-amdhsa`](rust-lang/rust#134740).
  - [`x86_64-pc-cygwin`](rust-lang/rust#134999).
  - [`{mips,mipsel}-mti-none-elf`]
    (rust-lang/rust#135074).
    Initial bare-metal support.
  - [`m68k-unknown-none-elf`](rust-lang/rust#135085).
  - [`armv7a-nuttx-{eabi,eabihf}`, `aarch64-unknown-nuttx`, and
    `thumbv7a-nuttx-{eabi,eabihf}`]
    (rust-lang/rust#135757).

Refer to Rust's [platform support page][platform-support-doc]
for more information on Rust's tiered platform support.

Libraries
---------
- The type of `FromBytesWithNulError` in `CStr::from_bytes_with_nul(bytes:
  &[u8]) -> Result<&Self, FromBytesWithNulError>` was [changed from
  an opaque struct to an enum]
  (rust-lang/rust#134143), allowing users
  to examine why the conversion failed.
- [Remove `RustcDecodable` and `RustcEncodable`.]
  (rust-lang/rust#134272)
- [Deprecate libtest's `--logfile` option.]
  (rust-lang/rust#134283)
- [On recent versions of Windows, `std::fs::remove_file` will now
  remove read-only files.]
  (rust-lang/rust#134679)

Stabilized APIs
---------------

- [`{float}::next_down`]
  (https://doc.rust-lang.org/stable/std/primitive.f64.html#method.next_down)
- [`{float}::next_up`]
  (https://doc.rust-lang.org/stable/std/primitive.f64.html#method.next_up)
- [`<[_]>::get_disjoint_mut`]
  (https://doc.rust-lang.org/stable/std/primitive.slice.html#method.get_disjoint_mut)
- [`<[_]>::get_disjoint_unchecked_mut`]
  (https://doc.rust-lang.org/stable/std/primitive.slice.html#method.get_disjoint_unchecked_mut)
- [`slice::GetDisjointMutError`]
  (https://doc.rust-lang.org/stable/std/slice/enum.GetDisjointMutError.html)
- [`HashMap::get_disjoint_mut`]
  (https://doc.rust-lang.org/std/collections/hash_map/struct.HashMap.html#method.get_disjoint_mut)
- [`HashMap::get_disjoint_unchecked_mut`]
  (https://doc.rust-lang.org/std/collections/hash_map/struct.HashMap.html#method.get_disjoint_unchecked_mut)
- [`NonZero::count_ones`]
  (https://doc.rust-lang.org/stable/std/num/struct.NonZero.html#method.count_ones)
- [`Vec::pop_if`]
  (https://doc.rust-lang.org/std/vec/struct.Vec.html#method.pop_if)
- [`sync::Once::wait`]
  (https://doc.rust-lang.org/stable/std/sync/struct.Once.html#method.wait)
- [`sync::Once::wait_force`]
  (https://doc.rust-lang.org/stable/std/sync/struct.Once.html#method.wait_force)
- [`sync::OnceLock::wait`]
  (https://doc.rust-lang.org/stable/std/sync/struct.OnceLock.html#method.wait)

These APIs are now stable in const contexts:

- [`hint::black_box`]
  (https://doc.rust-lang.org/stable/std/hint/fn.black_box.html)
- [`io::Cursor::get_mut`]
  (https://doc.rust-lang.org/stable/std/io/struct.Cursor.html#method.get_mut)
- [`io::Cursor::set_position`]
  (https://doc.rust-lang.org/stable/std/io/struct.Cursor.html#method.set_position)
- [`str::is_char_boundary`]
  (https://doc.rust-lang.org/stable/std/primitive.str.html#method.is_char_boundary)
- [`str::split_at`]
  (https://doc.rust-lang.org/stable/std/primitive.str.html#method.split_at)
- [`str::split_at_checked`]
  (https://doc.rust-lang.org/stable/std/primitive.str.html#method.split_at_checked)
- [`str::split_at_mut`]
  (https://doc.rust-lang.org/stable/std/primitive.str.html#method.split_at_mut)
- [`str::split_at_mut_checked`]
  (https://doc.rust-lang.org/stable/std/primitive.str.html#method.split_at_mut_checked)

Cargo
-----
- [When merging, replace rather than combine configuration keys
  that refer to a program path and its arguments.]
  (rust-lang/cargo#15066)
- [Error if both `--package` and `--workspace` are passed but the
  requested package is missing.]
  (rust-lang/cargo#15071) This was previously
  silently ignored, which was considered a bug since missing packages
  should be reported.
- [Deprecate the token argument in `cargo login` to avoid shell history leaks.]
  (rust-lang/cargo#15057)
- [Simplify the implementation of `SourceID` comparisons.]
  (rust-lang/cargo#14980) This may
  potentially change behavior if the canonicalized URL compares
  differently in alternative registries.

Rustdoc
-----
- [Add a sans-serif font setting.]
  (rust-lang/rust#133636)

Compatibility Notes
-------------------
- [The `wasm_c_abi` future compatibility warning is now a hard error.]
  (rust-lang/rust#133951)
  Users of `wasm-bindgen` should upgrade to at least version 0.2.89,
  otherwise compilation will fail.
- [Remove long-deprecated no-op attributes `#![no_start]` and `#![crate_id]`.]
  (rust-lang/rust#134300)
- [The future incompatibility lint `cenum_impl_drop_cast` has been
  made into a hard error.]
  (rust-lang/rust#135964) This means it is
  now an error to cast a field-less enum to an integer if the enum
  implements `Drop`.
- [SSE2 is now required for "i686" 32-bit x86 hard-float targets;
  disabling it causes a warning that will become a hard error
  eventually.]
  (rust-lang/rust#137037) To compile for
  pre-SSE2 32-bit x86, use a "i586" target instead.

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.

- [Build the rustc on AArch64 Linux with ThinLTO + PGO.]
  (rust-lang/rust#133807)
  The ARM 64-bit compiler (AArch64) on Linux is now optimized with
  ThinLTO and PGO, similar to the optimizations we have already
  performed for the x86-64 compiler on Linux. This should make it
  up to 30% faster.
