+## Next release
+(Add new changes here, and they will be copied to the change section for the
+ next release)
+
+### Core libraries
+
+#### `dart:io`
+
+* **Breaking change**: Added `IOOverrides.serverSocketBind` to aid in writing
+  tests that wish to mock `ServerSocket.bind`.
+
+### Dart VM
+
+* New fields added to existing instances by a reload will now be initialized
+lazily, as if the field was a late field. This makes the initialization order
+program-defined, whereas previously it was undefined.
+
+### Tools
+
+#### Linter
+
+The Linter was updated to `0.1.103`, which includes:
+
+* updates to `prefer_relative_imports` to use a faster and more robust way to check for self-package references
+* updates to our approach to checking for `lib` dir contents (speeding up `avoid_renaming_method_parameters` and
+  making `prefer_relative_imports` and `public_member_api_docs` amenable to internal package formats -- w/o pubspecs)
+
+#### Pub
+
+* `pub get` generates [`.dart_tools/package_config.json`](https://github.com/dart-lang/language/blob/62c036cc41b10fb543102d2f73ee132d1e2b2a0e/accepted/future-releases/language-versioning/package-config-file-v2.md)
+  in addition to `.packages` to support language versioning.
+
+* `pub publish` now warns about the old flutter plugin registration format.
+
+* `pub publish` now warns about the `author` field in pubspec.yaml being.
+  obsolete.
+
+* Show a proper error message when `git` is not installed.

+This package contains logic that is shared between the front_end and
+analyzer packages.  It is intended solely to facilitate development of
+the Dart SDK, and is not intended for use by end users.  In
+particular, this package has no public API, so no guarantee is made of
+compatibility between one version of the package and the next.
+
+End users should consider using the analyzer package to analyze Dart
+source code.
