May 2026 (2026-05) monthly summary for vlang/v. This period focused on delivering high-impact features, strengthening reliability, and enhancing developer experience to drive business value through better interoperability, security, and tooling. Key outcomes: - IPv6 canonicalization improvements: Implemented pure-V RFC 5952 compliant IPv6 canonicalization and enhanced Ip6.str() to remove deprecated libc-dependent formatting, improving networking correctness and interoperability. - CBOR serialization module (RFC 8949): Introduced a dedicated encoding/decoding module enabling efficient cross-language data interchange for complex data structures. - Integer overflow stability: Fixed atou64 overflow handling to prevent silent wrapping, ensuring accurate parsing of large numbers in critical data paths. - Preserve fully-qualified enum names in fixed-array size expressions: Improved stringification to retain enum context, aiding compiler/type-inference correctness. - OS CSPRNG for UUIDs/ULIDs: Migrated UUID/ULID generation to the OS-provided cryptographically secure RNG, enhancing security and randomness quality in identifiers. - Structured CLI help output: Added grouped commands, inherited flags, examples, and learning resources to improve usability and learnability of the CLI. - MCP server example aligned with 2025-11-25 spec: Delivered a comprehensive MCP server example with tool registration, resource management, prompt handling, and progress notifications, supporting integration and adoption. Overall impact and accomplishments: - Strengthened core library capabilities (networking, serialization, crypto, CLI UX) while maintaining performance. - Improved security posture through OS-backed RNG and safer numeric parsing. - Enhanced developer productivity and integration readiness via better CLI/docs and MCP example. Technologies/skills demonstrated: - Systems programming, RFC standards adherence (RFC 5952, RFC 8949) - Safe numeric parsing and overflow handling - Cryptographic RNG usage, UUID/ULID generation - Data serialization formats and cross-language interoperability - CLI/UX design and documentation - Compiler/type inference improvements and robust stringification
