# Changelog



## [0.5.0] - 2026-03-22



### Added



- Top-3 provider bridges for `IBM Runtime`, `AWS Braket`, and `Azure Quantum` with typed lifecycle contracts.

- Cross-provider capability preflight and normalized error taxonomy.

- OpenTelemetry observability profiles (`high_level`, `granular`, `forensics`) plus deterministic fingerprint and portability telemetry contracts.

- Provider migration packs, support tiers, and reproducible provider benchmark matrix for v0.5 release evidence.



### Improved



- State-vector execution planning and hot-path performance, including real-only fast path for compatible `:pauli_z` workflows.

- Deep-circuit benchmark latency (`deep_6q`) with new planning and evolution optimizations.



### Docs



- v0.5 feature spec, acceptance criteria, provider implementation plan, migration packs, benchmark matrix, and observability guides finalized.
