Checker Framework 3.49.0

Version 3.49.0 (February 3, 2025)

User-visible changes:

The Optional Checker is more precise for Optional values resulting from
operations on container types (e.g., List, Map, Iterable). It supports
two new annotations:

• @NonEmpty
• @UnknownNonEmpty

The Signature Checker no longer supports @BinaryNameWithoutPackage because
it is equivalent to @Identifier; use @Identifier instead.

The JavaStubifier implementation now appears in package org.checkerframework.framework.stubifier.JavaStubifier.
