+## [1.0.0] - 2026-08-15
+
+First public release.
+
+### Added
+- Multi-horizon forecasting: 18 direct heads (3 targets x 6 horizons) using
+  exponentially weighted recursive least squares with a capped covariance trace.
+- Hedge-blended ensemble over persistence, climatology and the learned model,
+  so the system can conclude that the learned model is not worth using.
+- Adaptive conformal prediction intervals with coverage feedback.
+- Constant-velocity Kalman bank (Joseph form) for level and rate estimation.
+- Grey-box CPU self-heating compensation with an RLS-estimated coefficient,
+  calibrated from a single trusted thermometer reading.
+- Harmonic climatology with anomaly decay for a 7-day outlook, with annual
+  terms gated behind 120 days of history.
+- Precipitation model: Zambretti barometric prior plus an online logistic
+  residual learner with human-in-the-loop labelling.
+- Monitoring: Mahalanobis EWMA novelty, Page-Hinkley drift detection that
+  triggers retraining, and stuck-sensor detection.
+- Verification loop scoring every matured forecast against persistence and
+  climatology, surfaced as a public scorecard.
+- Tiered storage: raw to 5-minute to hourly downsampling, roughly 30 MB per year.
+- Arbitrary-range history queries, per-day summaries, all-time records and
+  streamed CSV export.
+- Five-tab dashboard sized to a single viewport, with a Methods tab generated
+  from the live configuration.
+- LED matrix driver with pressure-trend arrows, rain bars and alert pulses.
+- Physics-based simulator fallback so the suite runs without a Sense HAT.
+- Backfill and walk-forward backtest scripts.
