## [1.0.4] - 2026-01-05
9+
10+
### Performance
11+
- **Static Translator Cache** - Eliminates repeated file I/O across validation instances
12+
- TranslationManager now uses process-wide cached translator instance
13+
- Translation file loaded once per PHP process instead of per DataVerify instance
14+
15+
### Infrastructure
16+
- All benchmarks now run with OPcache enabled for production-realistic results
