0.2.0 Release

[0.2.0] — 2026-04-02

Breaking

• NRPT return signature — refactored nrpt / nrpt_adaptive to remove unused
  return values; callers that destructure the full tuple will need updating

Added

• Observer support for NRPT — collect per-round samples via pluggable observers
• Tuning diagnostics — utilities for inspecting adaptive schedule behaviour
• ising_sample wrapper — high-level convenience function for Ising model sampling
• Template EBM/program objects — nrpt_adaptive and discover_chain_count now
  accept a template object directly, reducing boilerplate
• Boundary energy ↔ NRPT integration — connected boundary_energy module to the
  NRPT pipeline
• NRPT correctness test

Fixed

• Random key propagation and block-edge validation in dynamic blocks
• Flaky TestBigGrid stabilized
• Lazy import guard for docs build
• MkDocs warnings resolved

Changed

• Internal NRPT refactor (cleaner scan carry, simplified state threading)
• Removed old benchmarks
• Refreshed example notebooks
• Converted leftover thrml references in docs
