# Liquidity Score Changelog

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

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

## v2.2 - No-pool rows moved to NR semantics

**Effective:** 2026-02-27

Coins without DEX pools switched from score=0 placeholders to NULL (NR) semantics.

- No-liquidity rows now persist liquidity_score as NULL instead of 0
- Daily history placeholders for no-pool coins also use NULL scores
- Downstream consumers can distinguish not-rated from genuinely low-liquidity assets
