##### Language

- **Breaking Change** [#&#8203;55418][]: The context used by the
compiler to perform
type inference on the operand of an `await` expression has been changed
to
match the behavior of the analyzer. This change is not expected to make
any
    difference in practice.

- **Breaking Change** [#&#8203;55436][]: The context used by the
compiler to perform
type inference on the right hand side of an "if-null" expression (`e1 ??
e2`)
has been changed to match the behavior of the analyzer. change is
expected to
    have low impact on real-world code. But in principle it could cause
compile-time errors or changes in runtime behavior by changing inferred
    types. The old behavior can be restored by supplying explicit types.

##### Libraries

##### `dart:core`

- **Breaking Change** [#&#8203;44876][]: `DateTime` on the web platform
now stores
microseconds. The web implementation is now practically compatible with
the
native implementation, where it is possible to round-trip a timestamp in
    microseconds through a `DateTime` value without rounding the lower
digits. This change might be breaking for apps that rely in some way on
the
`.microsecond` component always being zero, for example, expecting only
three
    fractional second digits in the `toString()` representation. Small
discrepancies in arithmetic due to rounding of web integers may still
occur
for extreme values, (1) `microsecondsSinceEpoch` outside the safe range,
corresponding to dates with a year outside of 1685..2255, and (2)
arithmetic
(`add`, `subtract`, `difference`) where the `Duration` argument or
result
    exceeds 570 years.

##### `dart:io`

- **Breaking Change** [#&#8203;55786][]: `SecurityContext` is now
`final`. This means
that `SecurityContext` can no longer be subclassed. `SecurityContext`
subclasses were never able to interoperate with other parts of
`dart:io`.

- A `ConnectionTask` can now be created using an existing
`Future<Socket>`.
    Fixes [#&#8203;55562].

##### `dart:typed_data`

- **Breaking Change** [#&#8203;53785][]: The unmodifiable view classes
for typed data
    have been removed. These classes were deprecated in Dart 3.4.

    To create an unmodifiable view of a typed-data object, use the
    `asUnmodifiableView()` methods added in Dart 3.3.

- Added superinterface `TypedDataList` to typed data lists, implementing
both
`List` and `TypedData`. Allows abstracting over all such lists without
losing
    access to either the `List` or the `TypedData` members.
    A `ByteData` is still only a `TypedData`, not a list.

[#&#8203;53785]: https://togithub.com/dart-lang/sdk/issues/53785

##### `dart:js_interop`

- **Breaking Change** [#&#8203;55508][]: `importModule` now accepts a
`JSAny` instead
of a `String` to support other JS values as well, like
`TrustedScriptURL`s.

- **Breaking Change** [#&#8203;55267][]: `isTruthy` and `not` now return
`JSBoolean`
    instead of `bool` to be consistent with the other operators.

- **Breaking Change** `ExternalDartReference` no longer implements
`Object`.
`ExternalDartReference` now accepts a type parameter `T` with a bound of
`Object?` to capture the type of the Dart object that is externalized.
    `ExternalDartReferenceToObject.toDartObject` now returns a `T`.
`ExternalDartReferenceToObject` and `ObjectToExternalDartReference` are
now
extensions on `T` and `ExternalDartReference<T>`, respectively, where `T
extends Object?`. See [#&#8203;55342][] and [#&#8203;55536][] for more
details.

- Fixed some consistency issues with `Function.toJS` across all
compilers.
Specifically, calling `Function.toJS` on the same function gives you a
new JS
function (see issue [#&#8203;55515][]), the maximum number of arguments
that are
passed to the JS function is determined by the static type of the Dart
function, and extra arguments are dropped when passed to the JS function
in
    all compilers (see [#&#8203;48186][]).
