Release v0.11.0 · google/cel-java

Features

Introduced a new extension library for Two-variable comprehensions support
- (example: <list>.all(indexVar, valueVar, <predicate>) -> bool)
Added support for type name Aliasing and Abbreviations to perform name resolution across multiple namespaces.
CEL Policy Compiler now supports the imports keyword to abbreviate type names.
Added the capability to export a CEL environment, including its standard libraries and extensions, into YAML.
Expanded the lists extension library with new functions: slice, distinct, reverse, sort, and sortBy.

PR #769 removes setContainer(String) method on the Cel, CelCompiler, and CelChecker builders. Callers must use setContainer(CelContainer) instead, which supports aliasing and abbreviations in addition to existing container resolution. For a migration that preserves existing behavior, simply provide CelContainer.ofName(string).
PR #789 changes the internal representation of CEL's null and bytes literals (e.g., b'foo') to their CEL-native Java type equivalents (dev.cel.common.Values.NullValue and dev.cel.common.values.CelByteString) instead of their Protobuf counterparts (com.google.protobuf.NullValue and com.google.protobuf.ByteString). This is currently a breaking change only if your codebase references these literals through the CelConstant AST node. There are no observable changes in evaluation behavior, as this is currently controlled by a feature flag. We plan on enabling this by default in a future release.

Fixed the filter/map macro to be linear in time and space complexity in #746.
Fixed unknown merging to be linear in space complexity when referenced in binds in #770.

Fixed replaceSubtree to properly populate source info for the three-argument map macro in #794.
