v0.1.5 - arena-backed allocation and evaluation fast paths

• Date: 2026-04-12
• Version: v0.1.5

Summary: This release includes arena-backed allocation for decoded terms and constants, an ed25519 verification cache, evaluator fast paths for common lambda application patterns, and decoding and cost-accounting updates that reduce allocation overhead.

New Features

• Added arena-backed allocation for decoded terms and constants to reduce allocation overhead during evaluation.
• Added an ed25519 verification cache to reduce repeated signature verification overhead.
• Added environment skip pointers to reduce environment traversal overhead in common evaluation paths.
• Added lambda-application fast paths to reduce overhead in common call patterns.
• Added support for configuring the benchmark root directory via PLUTIGO_BENCH_DIR.

Bug Fixes

• Fixed constant handling to behave more consistently across decoding and runtime evaluation.
• Fixed arena lifecycle management so temporary allocations were released after Machine.Run completes.

Performance

• Updated CBOR decoding to allocate decoded values from arenas to reduce per-decode allocations.
• Updated value and builtin allocation to reduce peak memory usage by reusing instances, adapting arena sizes, and reusing no-arg builtin instances.
• Updated decoding to use smaller input chunks by reducing the data decoding chunk size from 256 to 64.
• Updated memory-cost accounting to more accurately reflect allocation behavior under arena-backed reuse.

Additional Changes

• Updated test coverage to validate caching, arena reuse, and evaluator fast-path behaviors.

v0.1.4 - arena-backed CBOR decoding and runtime cleanup

• Date: 2026-04-10
• Version: v0.1.4

Summary: This release includes arena-backed CBOR decoding for additional PlutusData primitives, retained arena cleanup after Machine.Run, and improved constant handling to reduce memory pressure.

New Features

• Added arena-backed CBOR decoding for PlutusData maps, lists, integers, and byte strings to reduce per-decode allocations and improve reuse across operations.

Bug Fixes

• Fixed retained arena state leaking between executions by ensuring arenas are cleared after Machine.Run completes.

Performance

• Improved constant handling to reduce memory pressure during repeated decoding and evaluation workloads.
