+- Update to 1.18.0
+-Language updates:
+    + [Stabilize pub(restricted)][40556] `pub` can now accept amodule path to
+      make the item visible to just that module tree. Also accepts the keyword
+      `crate` to make something public to the whole crate but not users of the
+      library. Example: `pub(crate) mod utils;`. [RFC 1422].
+    + [Stabilize `#![windows_subsystem]` attribute][40870] conservative exposure of the
+      `/SUBSYSTEM` linker flag on Windows platforms. [RFC 1665].
+    + [Refactor of trait object type parsing][40043] Now `ty` in macros can accept
+      types like `Write + Send`, trailing `+` are now supported in trait objects,
+      and better error reporting for trait objects starting with `?Sized`.
+    + [0e+10 is now a valid floating point literal][40589]
+    + [Now warns if you bind a lifetime parameter to 'static][40734]
+    + [Tuples, Enum variant fields, and structs with no `repr` attribute or with
+      `#[repr(Rust)]` are reordered to minimize padding and produce a smaller
+      representation in some cases.][40377]
+-Compiler updates
+    + [rustc can now emit mir with `--emit mir`][39891]
+    + [Improved LLVM IR for trivial functions][40367]
+    + [Added explanation for E0090(Wrong number of lifetimes are supplied)][40723]
+    + [rustc compilation is now 15%-20% faster][41469] Thanks to optimisation
+      opportunities found through profiling
+    + [Improved backtrace formatting when panicking][38165]
+- Library updates:
+    + [Specialized `Vec::from_iter` being passed `vec::IntoIter`][40731] if the
+      iterator hasn't been advanced the original `Vec` is reassembled with no actual
+      iteration or reallocation.
+    + [Simplified HashMap Bucket interface][40561] provides performance
+      improvements for iterating and cloning.
+    + [Specialize Vec::from_elem to use calloc][40409]
+    + [Fixed Race condition in fs::create_dir_all][39799]
+    + [No longer caching stdio on Windows][40516]
+    + [Optimized insertion sort in slice][40807] insertion sort in some cases
+      2.50%~ faster and in one case now 12.50% faster.
+    + [Optimized `AtomicBool::fetch_nand`][41143]
+- Stabilized APIs:
+    + [`Child::try_wait`]
+    + [`HashMap::retain`]
+    + [`HashSet::retain`]
+    + [`PeekMut::pop`]
+    + [`TcpStream::peek`]
+    + [`UdpSocket::peek`]
+- Misc:
+    + [rustdoc can now use pulldown-cmark with the `--enable-commonmark` flag][40338]
+    + [Added rust-winbg script for better debugging on Windows][39983]
+    + [Rust now uses the official cross compiler for NetBSD][40612]
+    + [rustdoc now accepts `#` at the start of files][40828]
+    + [Fixed jemalloc support for musl][41168]
+- Compatibility Notes:
+    + [Changes to how the `0` flag works in format!][40241] Padding zeroes are now
+      always placed after the sign if it exists and before the digits. With the `#`
+      flag the zeroes are placed after the prefix and before the digits.
+    + [Due to the struct field optimisation][40377], using `transmute` on structs
+      that have no `repr` attribute or `#[repr(Rust)]` will no longer work. This has
+      always been undefined behavior, but is now more likely to break in practice.
+    + [The refactor of trait object type parsing][40043] fixed a bug where `+` was
+      receiving the wrong priority parsing things like `&for<'a> Tr<'a> + Send` as
+      `&(for<'a> Tr<'a> + Send)` instead of `(&for<'a> Tr<'a>) + Send`
+    + [Overlapping inherent `impl`s are now a hard error][40728]
+    + [`PartialOrd` and `Ord` must agree on the ordering.][41270]
+    + [`rustc main.rs -o out --emit=asm,llvm-ir`][41085] Now will output
+      `out.asm` and `out.ll` instead of only one of the filetypes.
+    + [ calling a function that returns `Self` will no longer work][41805] when
+      the size of `Self` cannot be statically determined.
+    + [rustc now builds with a "pthreads" flavour of MinGW for Windows GNU][40805]
+      this has caused a few regressions namely:
+    + Changed the link order of local static/dynamic libraries (respecting the
+      order on given rather than having the compiler reorder).
+    + Changed how MinGW is linked, native code linked to dynamic libraries
+      may require manually linking to the gcc support library (for the native
+      code itself)
