The release of Bevy 0.18 brings major rendering updates to the open-source engine, focusing on environmental realism. Developers can now utilize generalized atmospheric scattering and PBR shading improvements right out of the box, narrowing the visual gap with proprietary tools.

On the architectural side, the move to scenario-driven Cargo features promises to optimize build times and binary sizes significantly. As the engine matures, this modular approach signals a strong focus on production-readiness for professional workflows.

In today’s Rust recap:

> Bevy 0.18 adds atmospheric scattering and modular builds

> Dimforge migrates Rapier to glam and revives Kiss3d

> cargo-semver-checks expands to 242 lints with faster execution

> Kreuzberg v4 rewrites document extraction in pure Rust

Bevy 0.18 adds atmosphere occlusion and PBR shading

The Recap:Bevy 0.18 has officially launched on crates.io, bringing significant rendering capabilities like generalized atmospheric scattering alongside major workflow improvements. This release focuses on giving developers tools to create photorealistic environments while streamlining the build process through better modularity. Check out the release.

Unpacked:

  • New generalized scattering capabilities enable designing customizable atmospheric media—from Martian landscapes to foggy coastlines—by exposing parameters that were previously hard-coded to Earth-like values. Read the pull request

  • The introduction of scenario-driven Cargo features allows developers to compile only the specific engine modules required for 2D, 3D, or UI projects, significantly reducing binary sizes. See the migration guide

  • Procedural atmosphere occlusion now ensures sunlight dynamically changes color based on the sun's angle relative to the horizon, adding realistic orange and red hues without manual intervention. View the details

Bottom line: These graphical advancements close the gap between Bevy and established proprietary engines by offering high-fidelity rendering features out of the box. Prioritizing modular compilation demonstrates a clear commitment to improving iteration speeds and developer experience in the Rust ecosystem.

The glam Era: Dimforge Migrates Rapier and Revives Kiss3d

The Recap: Dimforge has overhauled its entire physics and graphics stack by migrating Rapier and Parry to glam, aligning with the broader Rust gamedev ecosystem. This strategic shift coincides with the revival of the Kiss3d engine, now modernized with WebGPU support and an async-first API. Read the full announcement.

Unpacked:

  • Optimizations including a new Dynamic BVH and sparse voxel colliders have boosted Rapier's web performance by 2x to 5x compared to previous versions. See the benchmarks

  • The physics stack now utilizes glam instead of nalgebra, a pivot designed to enable first-class support for the rust-gpu compiler backend and simplify linear algebra for developers. Understand the migration

  • Kiss3d returns as a lightweight visualization alternative to complex ECS engines, featuring a rewritten backend based on WebGPU that unifies native and web rendering loops. Check out the engine

Bottom line: Standardizing on glam reduces friction between physics and graphics libraries, effectively removing a major barrier to interoperability in the Rust ecosystem. Reviving Kiss3d provides a crucial middle-ground tool for developers who need simple 3D visualization without the architectural overhead of a full game engine.

cargo-semver-checks Doubles Down: 242 Lints and Counting

The Recap:cargo-semver-checks experienced exponential growth in 2025, closing the year with 242 lints—more than double the previous year's count—to help maintainers prevent breaking changes. The tool also achieved a massive reduction in execution time while seamlessly supporting dozens of Rust compiler versions.

Unpacked:

  • The project added 122 new lints in a single year and reduced total execution time by 4x, with some individual checks becoming up to 10x faster despite the increased coverage.

  • A robust compatibility layer now supports 26 different format versions of rustdoc JSON, allowing the tool to function reliably across many Rust versions without requiring user intervention. Read the technical overview

  • Development efforts included discovering a soundness bug in Rust and significantly expanding the test matrix to ensure fearless upgrades for library authors.

Bottom line: Automating semantic versioning checks is critical for ecosystem stability, as manual verification is error-prone and unscalable. By decoupling linting logic from specific compiler internals, this tool ensures developers can confidently publish updates without accidentally breaking downstream dependencies.

Kreuzberg v4: Document Intelligence Rewritten in Rust

The Recap: Kreuzberg v4 arrives as a complete rewrite of the document intelligence library, replacing Python internals with Rust to boost performance and remove heavy system dependencies like Pandoc. Check out the repository

Unpacked:

  • The transition to a Rust core eliminates Python GIL bottlenecks, ensuring predictable performance and lower memory usage for data-intensive extraction tasks.

  • Support for 10 language bindings—including TypeScript, Go, and WebAssembly—allows engineering teams to standardize their document extraction engine across every part of their stack.

  • Native parsers now handle over 56 document formats directly, streamlining deployment for RAG and LLM pipelines by removing the need to manage external tools. Read the documentation

Bottom line: Replacing glue code with native Rust implementations drastically simplifies the deployment of complex data pipelines by removing fragile system dependencies. This release validates Rust as a superior foundation for polyglot libraries that require both high performance and broad interoperability.
