[0.2.0] - 2026-03-13

Added

  • x86_64-linux support via Apple's Rosetta Linux translator (JIT + AOT)
  • Rosettad AOT persistent cache at ~/.cache/hl-rosettad/ with automatic translation
  • VZ ioctl emulation for Rosetta AOT activation
  • DC ZVA emulation in shim for Rosetta JIT correctness
  • PI futex (FUTEX_LOCK_PI/UNLOCK_PI/TRYLOCK_PI) with dead-owner detection
  • COW fork via file-backed shared memory (zero-copy for aarch64)
  • clone(CLONE_VM) and ptrace for Rosetta's two-process JIT architecture
  • vDSO builder for Rosetta's clock_gettime fast path
  • Crash report generator for GitHub issue filing
  • 4-mode test matrix (hl-aarch64, hl-x64, lima-aarch64, lima-x64)
  • Haskell binary testing (pandoc, shellcheck) with glibc sysroot bundles
  • Homebrew tap: brew install zw3rk/hyper-linux/hl
  • Curl installer with SHA256 verification: curl -fsSL https://hyper-linux.app/install.sh | sh
  • macOS .pkg installer
  • Interactive release automation (dist/release.sh)
  • Cloudflare Workers site deployment

Changed

  • Syscall count: ~140 → 172
  • Stack size: 2MB → 8MB (4x2MB blocks, dynamic position)
  • Address space: up to 1TB with 48-bit IPA for Rosetta mode
  • Fork: COW path for aarch64 (instant, zero data copy), IPC path for Rosetta
  • I-cache coherence: IC IALLU after every syscall return

Fixed

  • AT_BASE always emitted in auxv (fixes musl x86_64 SIGFPE)
  • ELF page-tail zeroing (fixes glibc dl-minimal-malloc stale data)
  • PROT_NONE high-VA PTE creation (fixes x86_64 PIE mmap at 85TB)
  • TTBR1 kbuf re-initialization across execve
  • Multi-call binary argv preservation (busybox applet dispatch)
  • GHC shutdown deadlocks: PI futex dead-owner, eventfd/signalfd close races
  • Blocking syscall interruptibility (-EINTR after 1s for no-timeout futex)
  • Haskell sysroot RPATH discovery via fixpoint loop
  • Comprehensive clang-tidy lint-clean

Documentation

  • Man page: stack size, msync implementation, missing /proc paths, COW fork
  • README: project structure, install methods, syscall count
  • Site: futex count, stack layout, Rosetta AOT description
