Unreleased

0.1.4 — 2026-07-12

Added

  • Windows (x86_64) prebuilt binary (wrvm-x86_64-windows.exe). Release matrix builds it on windows-latest with a PowerShell Get-FileHash step for the .sha256 sidecar. On Windows the shim strategy is a copy of the wrvm exe to shims\iwasm.exe / shims\wamrc.exe (Windows symlinks need Developer Mode or admin); argv[0] dispatch handles the rest. .zip archives are now extracted end-to-end. CI matrix gains windows-latest. Not yet covered: usage-log caller detection (Linux /proc and macOS ps only) and wrvm setup for cmd.exe / PowerShell rc files — the shim + shims-on-PATH is enough for scripted use.
  • wasi-extensions installable on x86_64 hosts from upstream. WAMR ships one arch-less wamr-wasi-extensions-<ver>.zip per release; wrvm now recognizes that shape (Platform::matches_wasi_extensions_asset) and dispatches to a new archive::extract_zip when the picked asset has a .zip extension. Zero effect on the aarch64 mirror path, which already ships a per-runner tarball.

Fixed

  • wrvm --upgrade on a Homebrew-installed binary no longer fails with a confusing EACCES/EPERM when trying to atomically replace the brew-owned Cellar file. Selfupdate now canonicalizes the running executable, detects paths under /opt/homebrew/Cellar/wrvm/, /usr/local/Cellar/wrvm/, or /home/linuxbrew/.linuxbrew/Cellar/wrvm/, and prints a friendly notice pointing at brew upgrade wrvm (or brew update && brew upgrade wrvm if the formula index is stale). The background "newer version available" notifier is also suppressed in this case, since the advertised command wouldn't work.
  • shim::exec_or_run on non-unix platforms was missing the anyhow::Context import — a latent bug that only compiled through on Windows once CI actually built windows-latest. Fixed.

Changed

  • Test coverage grew from 5 (spec parsing only) to 49 by covering the file-touching modules directly.
  • Homebrew formula now chmod +x's the release asset before bin.install so the completion-generation step can execute the freshly installed binary.

Infrastructure

  • mirror-wamr-sync.yml scheduled workflow (Mon+Thu 06:00 UTC + manual dispatch) auto-mirrors new upstream WAMR releases: lists bytecodealliance/wasm-micro-runtime tags, filters to real MAJOR.MINOR.PATCH shape, and dispatches mirror-wamr.yml for any version missing a wamr-mirror-<ver> release on this repo. Rate-limited to 3/run, oldest-first.
  • release.yml gains an update-formula job that auto-patches Formula/wrvm.rb with real .sha256 values after each release (replaces the manual sed dance done at each of v0.1.0–v0.1.3).
  • ci.yml runs a smoke test on the built binary (--version, --help, completions, doctor) so runtime regressions surface before they ship.

0.1.3 — 2026-07-12

Fixed

  • wrvm doctor no longer reports "hook not found" when the rc uses the eval "$(wrvm shell-init)" line that wrvm setup writes. It now accepts the shims dir, wrvm shell-init, or # wrvm-managed:env as evidence that shell integration is wired.
  • wrvm doctor no longer lists the brew-linked wrvm binary as an external iwasm — canonicalizing the iwasm shim can resolve outside WRVM_HOME (e.g. into /opt/homebrew/bin/) even though the target identifies as wrvm. detect_external now skips binaries whose --version starts with wrvm .

0.1.2 — 2026-07-12

Added

  • wrvm setup — one-shot command that wires the shell integration into the user's login-shell rc file (idempotent via a # wrvm-managed:env tag). Complements wrvm shell-init (which just prints the snippet). The Homebrew caveat now points at wrvm setup because Homebrew sandboxes formula install steps and can't safely modify $HOME.
  • Homebrew formula now installs a stable snippet at #{prefix}/share/wrvm/wrvm.{sh,fish} so users who prefer source over wrvm setup have a fixed path to reference.

0.1.1 — 2026-07-12

Added

  • Intel macOS prebuilt binary (wrvm-x86_64-macos), cross-compiled from Apple Silicon (macos-14) to sidestep the macos-13 (Intel) runner queue.
  • wasi-extensions in the aarch64 mirror, built with wasi-sdk in mirror-wamr.yml. Existing mirror releases are unaffected; re-run the workflow for a version to add the variant.

Fixed

  • Homebrew formula chmods the release asset to 0755 before install so Homebrew's post-install completion generation can execute the binary.

0.1.0 — 2026-07-12

Added

  • Initial release. Pure-native single-binary version manager for WAMR.
  • Commands: install, list, current, path, default, use, upgrade, deactivate, shell-init, register, unregister, apps, usage, uninstall, verify, exec, completions, doctor, --upgrade.
  • Variants: iwasm (default), iwasm-gc-eh, wamrc, wasi-extensions.
  • Pass-through shims (shims/iwasm, shims/wamrc) with usage tracking to usage.log.
  • Storage layout under ~/.tegmentum/wrvm/; runtime versions extracted directly into runtimes/wamr/versions/<v>/<variant>/.
  • install.sh + Homebrew formula stub + GitHub Actions CI/release workflows.

Not shipped as a prebuilt binary in v0.1.0

  • Intel macOS (x86_64-apple-darwin): GitHub Actions macos-13 runners are consistently backlogged. Intel macOS users install via source (cargo build --release). Added via cross-compilation in Unreleased.

aarch64 support via mirror channel

  • WAMR upstream ships x86_64 assets only. wrvm bridges this by publishing an in-repo mirror release (tag wamr-mirror-<ver>) built from upstream source by the mirror-wamr GitHub Actions workflow. On aarch64 hosts, install transparently resolves runtime downloads from that mirror.
  • Mirrored variants (three of four): iwasm, iwasm-gc-eh, wamrc. The workflow caches LLVM across runs so the wamrc build amortizes across versions. wasi-extensions added in Unreleased (needs wasi-sdk).
  • Install verifies each mirror asset against its .sha256 sidecar (and honors an upstream digest field when present).
  • WRVM_RUNTIME_MIRROR=owner/repo overrides the mirror source.

Not supported (upstream limitation)

  • LTS designation: WAMR has no LTS cadence; wrvm install lts errors.
  • Self-hosting: WAMR mainline lacks WASI Preview 2 / component model / wasi:http, so wrvm cannot run its own logic as a wasm component on WAMR. wrvm is a native binary.
