# Yield Intelligence Changelog

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

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

## v1.1 - Launch-audit corrections for APY windowing and display

**Effective:** 2026-03-01

Early launch audit corrected APY window semantics and cleaned up yield stability presentation/lookup behavior.

- 7-day APY switched to timestamp-window filtering instead of proportional sample slicing
- Tier-1 previous exchange-rate reads were reused from cached lookup state
- Yield stability display normalized as a true 0-100 percentage in UI components
