From 58e96cd965130008588a9e2691d283a467864d7b Mon Sep 17 00:00:00 2001 From: Nuwan Date: Fri, 6 Mar 2026 09:56:04 +0530 Subject: [PATCH] docs: complete v1.7 milestone with Phases 28-30 v1.7 Performance Optimization shipped with 3 stable phases: - Phase 28: VU Meter Optimization (external store + RAF) - Phase 29: Context Optimization (memoized providers) - Phase 30: Component Memoization (React.memo wrappers) Phases 31-32 permanently reverted: - Selector composition with shallowEqual blocked main thread - State update changes caused VU/slider unresponsiveness Results: Page freezes eliminated, VU meters smooth, sliders responsive.
