Note

Low Risk
Mechanical version and generated-client updates; no application logic changes appear in this diff beyond release metadata.

Overview
Releases 0.223.0 by aligning workspace and client package versions from 0.222.0 to 0.223.0 (Rust workspace, Cargo.lock, Go/Python/Ruby/TypeScript bindings, Zed extension, and integ-test generators plus regenerated baml_client artifacts).

CHANGELOG and fern/pages/changelog.mdx document the user-facing addition: render_null_as output format option (#3822), bundled with this version bump.

This covers engine manifests, language client packages (Go, Python, Ruby, TypeScript, Rust, Zed, JetBrains, VS Code), integration test generator configs and generated client constants, bumpversion tracking configs, and changelog entries noting the render_null_as output format option.

• BoundaryML/baml#3109: Performs the same pattern of coordinated version-string bumps across the identical set of files (engine manifests, Go VERSION, multi-language client exports, generator configs).
• BoundaryML/baml#3233: Another coordinated version bump touching the same engine/Cargo.toml workspace version, lib_common.go VERSION, generated client __version__/version constants, and generators.baml generator versions.

Poem

🐇 Hop, hop, a number grows,
From two-two-two to two-two-three it goes!
Every manifest, gem, and .toml in line,
Each version string updated, oh so fine.
A changelog note for render_null_as too —
The rabbit stamps 0.223.0, brand new! 🎉
