June 2026: FBOSS versioning system modernization and build configuration across facebook/fboss. Eliminated remaining uses of versioned target platforms by migrating to modifiers, centralized version universes into a dedicated file (THIRD-PARTY-VERSIONS.bzl), and updated tests and build macros to use modifiers. Ensured the to_versions mapping aligns with the new universes and explicitly set modifiers for cpp_library targets while preserving versions where needed for binary builds to maintain constraint propagation (fbpkg). These changes reduce deprecated patterns, stabilize builds, and simplify long-term maintenance while minimizing risk during transition.
