Introduction to ps-locale-lv_LV-12.5.1.8000-1.cop.sha512

This localization package enables full Latvian (lv_LV) language support for Cisco Collaboration Systems, specifically designed for Unified Communications Manager (CUCM) 12.5.1 deployments requiring ISO 639/3166 regional compliance. Released under Cisco’s Q1 2025 software refresh cycle, it standardizes Latvian linguistic rules across device interfaces, administrative portals, and system-generated notifications.

The package supports SHA-512 cryptographic validation for secure deployment, ensuring file integrity during transmission. Compatible with CUCM 12.5.1 SU3 and later versions, it addresses localization gaps reported in previous iterations for Baltic region deployments.
