Implementation details:

• Deprecated QualifierHierarchy#getTypeQualifiers.
• Deprecated Analysis#Analysis(ProcessingEnvironment) and Analysis#Analysis(T, int, ProcessingEnvironment); use Analysis#Analysis(), Analysis#Analysis(int), Analysis#Analysis(T), and Analysis#Analysis(T, int) instead.

Checker Framework 2.9.0

Version 2.9.0, July 3, 2019

Renamed the Signedness Checker's @Constant annotation to @SignednessGlb.
Introduced an alias, @SignedPositive, for use by programmers.

Annotated the first argument of Opt.get and Opt.orElseThrow as @NonNull.

Removed meta-annotation @ImplicitFor:

• Use the new meta-annotation @QualifierForLiteral to replace @ImplicitFor(literals, stringpatterns).
• Use the meta-annotation @DefaultFor to replace @ImplicitFor(typeKinds, types).
• Use the new meta-annotation @UpperBoundFor to specify a qualifier upper bound for certain types.

• initialization.static.fields.uninitialized for uninitialized static fields
• unary.increment.type.incompatible and unary.decrement.type.incompatible
  replace some occurrences of compound.assignment.type.incompatible

Implementation detail: deprecated TreeUtils.skipParens in favor of TreeUtils.withoutParens which has the same specification.
