Caught in react app:
```
React.useEffect(() => {
isMountRef.current = false;
return () => {
isMountRef.current = true;
};
}, []);
```
->
```
React.useEffect(() => isMountRef.current = !1 , []);
```
Two problems: there were no unit tests guarding this, no good way of knowing when code gets deleted.

## Compatibility Notes
- [Enable by default the `LSX` target feature for LoongArch Linux targets](https://redirect.github.com/rust-lang/rust/pull/132140 )
- [The unstable `-Zprofile` flag (“gcov-style” coverage instrumentation) has been removed.](https://redirect.github.com/rust-lang/rust/pull/131829 ) This does not affect the stable flags for coverage instrumentation (`-Cinstrument-coverage`) and profile-guided optimization (`-Cprofile-generate`, `-Cprofile-use`), which are unrelated and remain available.
- Support for the target named `wasm32-wasi` has been removed as the target is now named `wasm32-wasip1`. This completes the [transition](https://redirect.github.com/rust-lang/compiler-team/issues/607 ) [plan](https://redirect.github.com/rust-lang/compiler-team/issues/695 ) for this target following [the introduction of `wasm32-wasip1`](https://redirect.github.com/rust-lang/rust/pull/120468 ) in Rust 1.78. Compiler warnings on [use of `wasm32-wasi`](https://redirect.github.com/rust-lang/rust/pull/126662 ) introduced in Rust 1.81 are now gone as well as the target is removed.
- [The syntax `&pin (mut|const) T` is now parsed as a type which in theory could affect macro expansion results in some edge cases](https://redirect.github.com/rust-lang/rust/pull/130635#issuecomment-2375462821 )
- [Legacy syntax for calling `std::arch` functions is no longer permitted to declare items or bodies (such as closures, inline consts, or async blocks).](https://redirect.github.com/rust-lang/rust/pull/130443#issuecomment-2445678945 )
- The `wasm32-unknown-emscripten` target's binary release of the standard library is now [built with the latest emsdk 3.1.68](https://redirect.github.com/rust-lang/rust/pull/131533 ), which fixes an ABI-incompatibility with Emscripten >= 3.1.42. If you are locally using a version of emsdk with an incompatible ABI (e.g. before 3.1.42 or a future one), you should build your code with `-Zbuild-std` to ensure that `std` uses the correct ABI.
- [Declaring functions with a calling convention not supported on the current target now triggers a hard error](https://redirect.github.com/rust-lang/rust/pull/129935 )
- [The next-generation trait solver is now enabled for coherence, fixing multiple soundness issues](https://redirect.github.com/rust-lang/rust/pull/130654 )

feat(allocator): implement IntoIterator for &mut Vec ( #8389 )
...
Implement `IntoIterator` for `&mut Vec` like `std::vec::Vec` does. This allows shorter and more idiomatic syntax.
Before:
```rs
for item in object.collection.iter_mut() {
// ...
}
```
After:
```rs
for item in &mut object.collection {
// ...
}
```

feat(minifier): compress x = x || 1 to x ||= 1 ( #8368 )
...
The simplified version of the evaluation of `a = a || b` is:
> AssignmentExpression : LeftHandSideExpression = LogicalORExpression || LogicalANDExpression
> 1. Let lRef be ? Evaluation of LeftHandSideExpression.
> 2. Let llRef be ? Evaluation of LogicalORExpression.
> 3. Let llVal be ? GetValue(llRef).
> 4. If ToBoolean(llVal) is true
> a. Perform ? PutValue(lRef, llVal).
> b. return llVal.
> 5. Let lrRef be ? Evaluation of LogicalANDExpression.
> 6. Let rRef be ? GetValue(lrRef).
> 7. Let rVal be ? GetValue(rRef). [Note GetValue(rRef) returns rRef itself]
> 8. Perform ? PutValue(lRef, rVal).
> 9. Return rVal.
The simplified version of the evaluation of `a ||= b` is:
> AssignmentExpression : LeftHandSideExpression ||= AssignmentExpression
> 1. Let lRef be ? Evaluation of LeftHandSideExpression.
> 2. Let lVal be ? GetValue(lRef).
> 3. If ToBoolean(lVal) is true, return lVal.
> 4. Let rRef be ? Evaluation of AssignmentExpression.
> 5. Let rVal be ? GetValue(rRef).
> 6. Perform ? PutValue(lRef, rVal).
> 7. Return rVal.
The difference of these is that
- the evaluation of `a` is done twice for `a = a || b`, one with `1. Let lRef be ? Evaluation of LeftHandSideExpression` and one with `2. Let llRef be ? Evaluation of LogicalORExpression.`. This is same with #8366 , #8367 .
- `PutValue(lRef, llVal)` is performed when `ToBoolean(lVal)` is `true`.
So `x = x || 1` can be compressed to `x ||= 1` when the conditions written in #8366 are met and `PutValue(lRef, llVal)` does not have a side effect. When `a` is a non-global identifier (and not a reference created by a `with` statement), these conditions are met.
