Changelog

Sandwich Hime follows semantic versioning after final v1. Compiler and nested runtime releases are versioned independently and listed together when they form one coordinated release.

Unreleased

Changed

• Linux/amd64 is the maintained execution, verification, artifact, and release target. WSL remains a Linux development environment; native Windows, macOS, and other targets are best-effort portability surfaces rather than release gates or compatibility promises.
• Release preflight now builds the supported Linux/amd64 candidate only and requires Linux platform evidence for RC/final publication.

Removed

• The native Windows PowerShell verifier and private multi-OS release-gate workflow. Historical platform evidence and best-effort portability code are retained without creating a support obligation.

v1.0.0-beta.2 — 2026-08-12

Compiler-only release; the unchanged Apache runtime remains sando/v1.0.0-beta.1 with ABI sando.v1.

Added

• Standard-library-only himesan lsp --stdio with one workspace per process, full-document overlays, 200 ms edit debounce, cancellation, and bounded indexing through the compiler's existing filesystem boundaries.
• Live diagnostics, trust warnings, duplicate/cycle reporting, UTF-16 LSP positions, tag/context/component hover, document symbols, typed component completion, and component go-to-definition.
• Additive features: ["lsp-stdio"] in himesan version --json.
• Protocol framing and malformed-input fuzzing; overlay, Unicode, CRLF, NUL, deletion, nested-module, symlink, completion, definition, cancellation, shutdown, no-write, and resource-limit tests.

Boundaries

The server does not generate, run Go or project code, fetch dependencies, access the network, start the dev supervisor, format, rename, add imports, or delegate general Go completion to gopls. Generated-file freshness remains an explicit himesan check --json workflow.

v1.0.0-beta.1 — 2026-08-12

This is the first installable public beta: sando/v1.0.0-beta.1 for the Apache-2.0 runtime and v1.0.0-beta.1 for the compiler and CLI. The beta is for learning, classroom projects, evaluation, and compatibility feedback. It is not a production-stability promise.

Added

• Typed one-component .sando language and explicit <?sando go target.
• Context-annotated renderer IR with deterministic, atomic Go generation.
• Read-only stale-output checking and structured diagnostics.
• Independent Apache-2.0 sando component/runtime ABI.
• Loopback-only last-good development supervisor with SSE reload and diagnostic overlay.
• Compiler-owned deterministic golden fixture and standalone release gates.
• Multi-license, security, governance, trademark, AI contribution, and release policies.
• Public beta support policy for evaluation and classroom use, including a provisional macOS lane and a community compatibility-reporting path.

Release verification

The exact public Beta 1 commit b7a84054d755e42285e50298e41e47f06a8325a5 (tree be9e118e38dfebed19f60403ededdadabe07d2aa) passed maintainer-run executed Linux and native Windows matrices with Go 1.25.12 and Go 1.26.5. The tested golden output had the same SHA-256 on each tested host: 63fa75a3049a3a8a12d769d7f9b6b510dfe763baacf706775b75cef2c57a984f.

The complete release preflight passed, including race tests, bounded parser fuzz smoke, known-vulnerability analysis of both zero-third-party-dependency modules, candidate-version provenance, and six cross-builds. The signed runtime and compiler tags were published in that order. Fresh direct and public-proxy runtime-first installs passed after normal proxy propagation. Native macOS execution remains pending and is explicitly provisional for this beta.

Known limitations

• Source syntax, generated format, CLI details, and runtime API may change before final v1.
• Native macOS behavior has not yet been maintainer-validated.
• In a shared fresh Go module cache, add the nested sando runtime before installing the parent compiler module at the same Beta 1 version.
• Prebuilt binary artifacts, checksums, SBOMs, reproducible archives, key-recovery rehearsal, systematic browser differential, long fuzz, benchmark, and final compatibility gates remain work toward the release candidate and final v1. Beta 1 itself is a signed source/module release.
• The project has no independent security audit, certification, or formal verification.

Removed since the private prototype

• Unpublished .go.hime syntax and the 2025 generated API.
• Injected helper directories, nested demo modules, Go plugins, and manually repaired generated output.
• Repository-bundled application examples and deployment-specific evidence.
• Placeholder novelty commands that did not perform project work.

Private prototype history is intentionally outside the sanitized public repository. The public changelog begins with Beta 1.
