- WASM plugin host (wasmtime 46, 17 host fns) + example noisemap plugin - Rhai scripting engine (12 API fns, `terrafier run` cmd) - i18n: en/ru translations, auto-detect, t! macro - GUI: pan (click-drag) + zoom (scroll wheel) with viewport transform - cargo-dist 0.31: MSI/pkg/shell installers, both binaries - CI: .github/workflows/ci.yml + release.yml - Security: wasmtime 30→46, bincode 1.3→2.0, quick-xml CVE docs - Code review: SAFETY comments, unwrap→match cleanup - Fixes: clippy approx_constant, needless_borrows, rustfmt
