Libzmq gains native support for AF_VSOCK sockets

A technical write-up explains how libzmq now supports AF_VSOCK, the Linux socket address family used for VM-to-hypervisor communication, originally developed by VMware as VMCI. The piece notes that while several languages already offer low-level AF_VSOCK bindings, no higher-level abstraction existed until this libzmq integration, which lets developers use familiar ZeroMQ patterns instead of manually handling raw socket calls.
