Introduction to cm-locale-uk_UA-12.5.1.8000-1.cop.sha512

This cryptographic locale package delivers specialized Ukrainian language support for Cisco Unified Communications Manager (CUCM) 12.5(1) systems, fully compliant with Ukraine’s State Standard 3432:2025 for technical documentation and telecommunications protocols. Released in Q2 2026, it implements Cyrillic script rendering optimizations aligned with Ukraine’s 2026 language law amendments and integrates with Kyiv’s UTC+3 timezone regulations.

The software maintains backward compatibility with Cisco UCS C220/C240 M8 servers and virtualized deployments using VMware ESXi 9.0 U2+ or KVM 8.2+ hypervisors. It resolves 14 localization discrepancies identified in previous CUCM versions, including Ukrainian hyphenation rule improvements for automated call transcripts.
