v0.10.0

0.10.0 (2026-11-09)

TruffleCEL 0.10.0 adopts published TruffleData 0.10.0 and completes this wave of
CEL tooling, embedding APIs, allocation reductions and regex hardening. Java 25
and Elide GraalVM 25.5.5-elide.27 remain the runtime baseline. All four Maven modules
release together: core, protobuf, JSON and the generated-adapter annotation processor.

Compatibility

RE2/J is now an optional Maven dependency. Compatibility-mode consumers must
explicitly declare com.google.re2j:re2j:1.8. Applications that accept the supported
TruffleRegex subset can opt into Cel.newBuilder().truffleRegexOnly(limit) or the
matching Polyglot options and omit RE2/J entirely. JVM and Native Image packaged
consumers verify matching and guest compilation with the JAR physically absent.
See integration and regex policy.

Functionality and fixes

• Editable syntax trees, custom macros, parser/checker recovery, canonical AST
  interchange, copied compiler environments and application validators.
• Lazy lexical bindings, opt-in common-subexpression elimination, conservative
  charged-operation bounds, field-level partial evaluation and qualified unknowns.
• Environment YAML, CEL Policy compilation, embedded source offsets, source-level
  tracing, asynchronous evaluation and per-call/non-strict function bindings.
• Reflection-free generated POJO/JavaBean/record snapshots, protobuf contexts and
  typed field-mask projections, with bounded owned snapshots and preserved extensions.
• Correctness fixes for diagnostic/source provenance, sorting budgets, policy
  conditions, AST round trips, long unary runs and native guest-compilation boundaries.
• Constant regex acceleration recovers after weak-handle collection in its owner
  context. Bounded caches evict one entry at a time and cache syntax-failure data
  without retaining exception stacks or weakening per-caller limits.

Performance and qualification

Evaluation contexts, binding conversion caches, shared layouts, cached-program
metadata, map snapshots and protobuf wire ingestion use less allocation or retained
storage in their documented comparisons. Scoped TruffleRegex accelerates constant
matches while retaining the tested compatibility fallback.

Fresh release measurements and charts
cover JVM/native evaluation, optimized cel-java, prepared-input controls, ingestion
allocation, and the separate compilation/image-AST comparison. Raw observations,
source/runtime/artifact identities, observed ranges and remaining memory gaps are
preserved. Timing wins do not establish universal optimality or smaller process RSS.

All 75 qualification targets pass, including conformance, packaged consumers,
allocation and native guest-JIT gates. Exact-version staging passes for all four
modules. Full-source coverage meets the unchanged 99.8% line/branch floors, and
CodSpeed classifies all 21 cases as unchanged against pre-adoption main.
