+- Most static analysis "hints" are converted to be "warnings," and any
+ remaining hints are intended to be converted soon after the Dart 3.0 release.
+ This means that any (previously) hints reported by `dart analyze` are now
+ considered "fatal" (will result in a non-zero exit code). The previous
+ behavior, where such hints (now warnings) are not fatal, can be achieved by
+ using the `--no-fatal-warnings` flag. This behavior can also be altered, on a
+ code-by-code basis, by [changing the severity of rules] in an analysis
+ options file.
+- Add static enforcement of the SDK-only `@Since` annotation. When code in a
+ package uses a Dart SDK element annotated with `@Since`, analyzer will report
+ a warning if the package's [Dart SDK constraint] allows versions of Dart
+ which don't include that element.
