# Release Summary: Ruchy v3.138.0

**Release Date**: 2025-10-27
**Release Link**: https://github.com/paiml/ruchy/releases/tag/v3.138.0

## Summary

Fixed critical parser bug (PARSER-081) where array literals failed after sequential let statements. Investigation led to comprehensive RuchyRuchy debugger enhancement proposal.

## Bug Fixed

### PARSER-081: Array Literals After Sequential Let Statements

**Problem**: `let y = 2\n[x, y]` was parsed as `2[x, y]` (invalid array indexing)

**Solution**: Modified postfix operator handling to skip array indexing after literals/struct literals

**Test Results**: 10/10 new tests passing, 4029 lib tests passing, all quality gates passing

**Investigation Time**: 3 hours → Led to 6x tooling improvement proposal

## RuchyRuchy Enhancement

**Issue**: https://github.com/paiml/ruchyruchy/issues/2

**Proposed**: Parser state visualization, AST diff views, operator precedence tracing

**Expected Impact**: 6x faster debugging (3 hours → 30 minutes)
