Full, detailed per-release notes live in RELEASE_NOTES.md; this file is the concise summary.

[Unreleased] — v5.1 (Correctness & quick wins)

Added

  • Golden-reference regression tests locking the TRP/gain integration core (isotropic EIRP → itself; upper hemisphere → −3.01 dB).
  • compute_group_delay_dispersion() — per-frequency group-delay variance/std across theta cuts (replaces the old dead TODO block).
  • Test coverage for previously-untested modules: plotting.py, save.py, groupdelay.py, plot_group_delay_cst.py, uwb_plotting.py.

Changed

  • cal_drift_report MCP tool now returns {output_path, format} / {error} and never raises to the client.
  • Slimmer install: openai moved to the [ai] extra; keyring/cryptography dropped from core deps (unused since the v5.0.0 AI removal); pyinstaller removed from the runtime requirements; numpy ceiling raised to <3.0.0.
  • GUI settings save/load and data-processing failures are now surfaced (stderr / log) instead of being silently swallowed.

Docs

  • This changelog; expanded reference docs.

[5.0.0] — 2026-05-28

Zero-dependency, MCP-first relaunch. Removed the entire in-app AI/LLM stack (chat, AI report generation, provider abstraction, API-key store) — RFlect makes no LLM/API calls and needs no key or subscription. generate_report is deterministic by default with an optional agent-authored narrative. Added 6 MCP tools (compare_antennas, analyze_s11, analyze_group_delay, estimate_link_budget, analyze_mimo_diversity, generate_active_cal); MCP tool count 35 → 41. Renamed ai_analysis.py → analysis_engine.py.

[4.3.0] — 2026-05-28

Multi-angle iperf throughput-validation MCP tool (analyze_iperf_angle_sweep).

[4.2.0] — 2026-05-12

process_folder single-call folder-orchestration MCP tool; MkDocs Material docs site.

[4.1.9] — 2026-04-14

Patch: restored the Active Chamber Calibration routine.

Earlier releases (4.1.8 and prior) are detailed in RELEASE_NOTES.md.
