v0.9.0

Note

If you encounter any compatibility issues with protobuf-java 4.x, use CEL-Java version 0.9.0-proto3 as a workaround. This is the same version as CEL-Java 0.9.0 with protobuf dependency pinned to 3.25.5.

Breaking Changes

In an effort to make protobuf an optional dependency in CEL-Java, the following PR changes the resolution of type(expr) from proto based cel.expr type value into native equivalent dev.cel.common.types.CelType:

• Expose CelType as a native representation for runtime type value. in #505

The following PR changes the resolution of unknown values from cel.expr unknown expr value into native equivalent dev.cel.runtime.CelUnknownSet:

• Enable adaptUnknownValueSetToNativeType by default in CelOptions in #490
• Remove adaptUnknownValueSetToNativeType flag from CEL in #496

The following PR removes previously deprecated methods that deal with canonical CEL expr values from CelTypes and CelAbstractSyntaxTree classes. The removed methods have been moved to CelProtoAbstractSyntaxTree and CelProtoTypes:

• Create CelProtoTypes utility class to handle CelExpr in proto format in #524
• Remove deprecated methods in CelTypes in #531
• Remove deprecated CelAbstractSyntaxTree#getProtoResultType in #533

What's Changed

• Add CelStandardDeclaration to allow environment subsetting for type-checker in #448
• Add CelStandardFunctions to allow environment subsetting for the runtime in #461
• Introduce late-bound functions into CEL-Java in #494
• Add option to enable updated accumulator variable. in #538
• Add CelOptions to disable string conversion and list/string concatenation in #506
• Add CelOptions to disable comprehension in #507

Fixes

• Enforce strictness of type function #474
• Fix macro parsing with receiver style args by @oridag in #481
• Use an immutable copy of DefaultDispatcher to avoid synchronization in #477

Miscellaneous

• Fix feature_request.md config blocks by @sergiitk in #485

• Remove unused test_java_proto package in #526

• Remove reference to CheckedExpr proto in DefaultMetadata in #521

• Migrate CelAttributeParser away from proto based expr to canonical cel expr in #522

• Add expr ID set as a field to CelUnknownSet. in #471

• Add a policy example that compiles then evaluates late bound functions in #497

• Migrate dev/cel/common/ tests to use proto3 canonical conformance protos follow up will address proto2. in #512

• Migrate dev/cel/extensions tests to use canonical conformance protos. in #513

• Remove unnecessary unknown value adaptation in ProtoAdapter in #499

• Migrate away from deprecated CelTypes methods in #525

• Remove the legacy createInterpretable(CheckedExpr) in #487

• Update runtime tests to refer to canonical cel conformance protos. in #510

• Correctly suppress AutoValueMutable warnings in #475

• Deprecate enableUnsignedLong option. Remove associated base interpreter tests. in #515

• Cleanup of unused methods and build targets in #469

• Move evaluateExpr utility methods to validator and optimizer in #470

• Update WORKSPACE dependencies in #530

• Remove references to deprecated type resolvers in the runtime. in #520
