Simple Language v0.9.8

[0.9.8] - 2026-04-28

Added

• SimpleOS bootstrap lane — bootstrap-from-scratch.sh --target=simpleos-x86_64 end-to-end with kernel build, package mode, and os_qemu_test.shs harness wired to the platform catalog
• Driver framework rollout (A–E) — pure-Simple @driver / @native_lib framework, manifest encoder, and DMA primitives across x86_64/x86/arm64/arm32/riscv64/riscv32 (FR-DRIVER-0001..0006)
• Rust stage1 sysroot — x86_64-unknown-simpleos libstd lane with ${SDKROOT} symlink shim
• MDSOC+ as default architecture for SimpleOS userland/apps (ECS business layer); kernel/drivers stay MDSOC-only
• Browser platform progress — Blink/Skia/cc/viz-style naming, WebGPU compute-draw extern, WSS handshake + TLS hardening
• TTF font path end-to-end via font_renderer with SIMPLE_TTF_DYLIB / SIMPLE_TTF_PATH env opt-ins
• t32_lsp_mcp cache opt-in — setup.sh gates SMF compile + use behind SIMPLE_MCP_USE_CACHE=1; default is .spl interpret

Fixed

• Cranelift right-shift (>>) — fixed in compiled mode (FR-DRIVER-0002b); driver-framework division workaround obsolete
• Submodule gitlink flips under jj ↔ git — accept submodule files-as-tree + .gitmodules + separate inner-repo push
• Release-binary error reporting — bin/simple <script.spl> (no run) now surfaces real errors on stderr (B1)
• Interpreter [u8] bulk allocation — rt_bytes_alloc(len) -> [u8] extern (B2); 32 MiB allocates in ~1.5s
• Clippy — simple-parser, simple-common, simple-native-all warnings eliminated; runtime build.rs (Path vs PathBuf) and serial.rs errno comparisons cleaned up
• VHDL backend — switch return targets, goto-return chains, scalar source-facade width ops, tuple/enum aggregates
• x86_64 kernel build — root-cause analysis for cross-arch riscv inline-asm leak (use --entry-closure)

Changed

• MCP wrapper default — runs from .spl by default; SMF cache strictly opt-in via SIMPLE_MCP_USE_CACHE=1
• bin/simple build — clarified that build falls through wrapper whitelist; new externs require scripts/bootstrap/bootstrap-from-scratch.sh --deploy
• SSpec compile pipeline — documented limitations; --mode=smf / --compile still produce false-greens; verify in interpreter mode until R2-broader lands
• Release prep workflow — local check_release_payload.shs, check-mcp-release-assets.shs, check-executable-size-budgets.shs, and check-loader-dependency-closure.shs smoke checks before tag
