Ant 12.2.8f8451f4.0

Package installs and dependency resolution are more deterministic

  • Added platform-aware package filtering using npm-compatible operating-system, CPU, and Linux libc/ABI names.
  • Upgraded ant.lockb to lockfile version 4 so platform ABI data is recorded consistently. Invalid or older lockfiles now trigger a fresh resolve and install instead of stopping at an invalid-lockfile error.
  • Added virtual package links that preserve each dependency's peer-dependency context instead of flattening incompatible peer environments together.
  • Improved registry-host caching and warmed-registry fallback deduplication.
  • Added ant install --force and ant update --force to ignore cached metadata, re-resolve dependencies, and safely replace cached package contents.
  • Fixed cache cleanup and retained-memory issues in forced installs.
  • Added metadata lookup for direct tarball URLs so packages installed from registry tarballs still resolve with their correct package metadata.
  • Added automatic npm_config_user_agent=ant/<version> for package executables launched through Ant.
  • Improved package trust output by listing blocked lifecycle scripts and the exact ant trust commands needed to run them.
  • Added lifecycle-build counts and clearer progress reporting to install, add, update, trust, and reinstall output.
  • Limited add/update summaries to the direct packages requested by the user.

ants.land publishing and tooling improved

  • Added multipart package publishing to the registry and ants.land CLI for larger package archives.
  • Added tarball hashing and multipart create, part-upload, and completion handling.

Servers and interactive input are easier to use

  • Added first-class Ant.serve(options) for starting a server programmatically instead of relying only on a module default export.
  • Ant.serve() now returns the live server object with hostname, port, url, stop, requestIP, timeout, upgradeWebSocket, and eventSource.
  • Listen failures now include Node-style code, errno, syscall, address, port, or Unix-socket path details.
  • Reworked readline and process.stdin around one shared input path so readline, keypress events, pause/resume, and data listeners cooperate correctly.
  • Fixed arrow-key decoding, sequential keypress delivery, stdin pausing, and piped-input handling.
  • Reduced per-byte work in readline key-sequence processing.

Node and web API compatibility expanded

  • Added dns.promises.resolve() support for A, AAAA, SRV, and TXT records through c-ares.
  • Made net.Socket and tls.TLSSocket inherit and initialize as duplex streams.
  • Added Buffer.prototype.compare() and Buffer.prototype.equals().
  • Added start/end bounds support to Buffer.prototype.toString().
  • Added proper DataView.prototype.buffer, byteLength, and byteOffset accessors.
  • Added Latin-1 conversion support to base64 and string-decoder paths.
  • Added PBKDF2 key import and SubtleCrypto.deriveBits() support for derived keys.
  • Added fs.symlinkSync() and expanded fs.cpSync() to preserve symlinks, file modes, filters, dereference options, and verbatim link targets.
  • Missing CommonJS packages now throw errors with code: 'MODULE_NOT_FOUND' from both require() and require.resolve().
  • Updated process, process.env, process.versions, process.features, and process.release to inherit standard object methods such as hasOwnProperty.
  • Optimized Headers and Response initialization while preserving content-type normalization and constructor behavior.

JavaScript async execution and control flow are more correct

  • Fixed async coroutine state corruption across nested generators, for await, and awaits that occur before a yield.
  • Fixed returns, throws, breaks, continues, and labeled jumps so they unwind through every required finally block.
  • Fixed async returns that previously skipped finally, including Promise.race() paths with pending competitors.
  • Fixed iterator-result undefined behavior affecting typed arrays, collections, headers, and Promise.all().
  • Made pending-promise garbage-collector tracking O(1) and scoped it per VM.
  • Added a generational write barrier for closed upvalues so captured values remain live across collections.
  • Fixed sloppy-mode arguments parameter aliasing, including after async activation materialization.
  • Fixed JIT-compiled derived constructors dropping the this value rebound by super().

Parser, object-model, and collection correctness improved

  • Corrected static class method parsing, computed class elements, and strict class-element compilation.
  • Fixed incorrect parsing of unparenthesized in expressions.
  • Fixed strict-mode reclassification for dynamically constructed functions.
  • Added non-registered symbols and native functions as valid WeakMap keys and WeakSet values.
  • Removed the legacy rope-length cap that could break very large concatenated property strings.
  • Improved builtin object construction and prototype consistency.

Silver JIT coverage and performance expanded

  • Added JIT support for optimized field reads and optional property/element access.
  • Added JIT support for nullish tests and nullish jumps.
  • Added JIT support for private-field reads and writes.
  • Added JIT support for stack NIP, prefix/postfix increment, and decrement operations.
  • Added virtual-stack slot reservation and more precise boxed/numeric slot tracking.
  • Fixed stale numeric-slot state after JIT void operations.
  • Added targeted JIT correctness tests and hit/miss benchmarks for fields, elements, nullish operations, private fields, stack manipulation, and increment/decrement.
  • Added dynamic-property, large-AST, React, response-construction, and decimal conversion performance workloads.
  • Updated the Darwin ARM64 PGO profile and expanded PGO training with server workloads.

WASI, sandboxing, and embedding moved forward

  • Added configurable WASI preopens instead of exposing only the current directory.
  • Fixed Darwin WASI native-call linkage.
  • Fixed AArch64 KVM boot-parameter parsing and exception-vector setup.
  • Added AArch64 sandbox register dumping for fault diagnosis and disabled unsupported DC ZVA use under KVM.
  • Updated libant to compile the platform sandbox backends into the static library.
  • Added libant allocator, native-tuning, LTO, and PGO build options.

Build, release, and project infrastructure improved

  • Added a reproducible Nix toolchain layer with LLVM 21 on Linux and an Apple-SDK-safe unwrapped Clang setup on macOS.
  • Added Cachix-backed Nix builds, system-partitioned vendor caches, stable output hashing, and ccache acceleration.
  • Fixed Nix cache trust configuration and prevented unintended linker overrides.
  • Fixed the Windows build after the runtime and tooling changes in this release.
  • Added a dedicated manifest API route and GitHub workflow that attach release-note URLs without changing artifact provenance.
  • Added vouch-managed contribution gating and automated vouch-list maintenance.

Testing coverage grew substantially

  • Added a manifest-driven package and runtime test harness with snapshot support.
  • Added focused harness groups for server, network, and HTTP benchmarking workloads.
  • Added compatibility snapshots for esbuild, Rolldown, React, Preact, tar, djot, Lua, pidtree, and smoke workloads.
  • Added regression coverage for Ant.serve, readline input, platform package resolution, peer-context linking, forced installs, lifecycle trust, multipart publishing, base64, PBKDF2, filesystem symlinks, CommonJS errors, async/finally unwinding, GC upvalues, WeakMap symbols, large ropes, and the expanded JIT surface.
