# Yield Intelligence Changelog

[All versions](https://pharos.watch/methodology/yield-changelog/)

<a id="changelog-v-2-1"></a>

## v2.1 - Warning-signal telemetry and fxUSD native mapping

**Effective:** 2026-03-01

Yield rows gained warning-signal state for anomaly detection, while deterministic pool coverage expanded with fxUSD native yield mapping.

- warning_signals persistence added with spike/divergence/trend/reward/TVL-outflow checks
- Signal detection now uses market-median APY and prior TVL context per coin
- Tier-2 deterministic source map added explicit fxUSD Stability Pool coverage

## v2.0 - Wave-1 coverage expansion and numerical hardening

**Effective:** 2026-03-01

Wave-1 expanded native/wrapper mappings and tightened core PYS stability math to avoid edge-case distortion.

- Added wave-1 variant/pool mappings for additional native-yield stablecoins
- Near-zero mean handling in stability/variance math prevents coefficient-of-variation blowups
- Safety fallback and finite-value guards were formalized for ranking writes
