+    methods on `java.lang.Object`, which can be disabled using
+    `--javacopts=-Xep:ReturnValueIgnored:OFF`
+
+Important changes:
+
+  - provider() has a new parameter: init, a callback for performing
+    pre-processing and validation of field values. Iff this parameter
+    is set,
+    provider() returns a tuple of 2 elements: the usual provider
+    symbol (which,
+    when called, invokes init) and a raw constructor (which bypasses
+    init).
