-## 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.
