# Changelog

All notable changes to the Go line (Reasonix 1.0+) are recorded here. The legacy
`0.x` TypeScript history lives on the [`v1`](https://github.com/esengine/DeepSeek-Reasonix/tree/v1)
branch.

## [1.0.0] — unreleased

First stable release — a **ground-up rewrite in Go**. Not an upgrade of the `0.x`
TypeScript line; a new codebase that becomes the default (`main-v2`).

### Highlights

- **Go kernel**: a single static binary (CGO-free), cross-compiled for
  darwin/linux/windows on amd64 + arm64. Distributed via npm (the package wraps
  the native binary) and release archives; no Node runtime needed to run it.
- **Agent core**: the loop, built-in tools (read/write/edit/multi_edit/glob/grep/
  ls/bash/web_fetch/todo_write), permission gate, sandboxed bash, and the
  DeepSeek prefix-cache–oriented design.
- **Subagents**: `task` plus explore/research/review/security_review skill agents.
- **Skills & hooks**: Claude-Code-style skills (`internal/skill`) and hooks
  (`internal/hook`), symlink-aware and slash-integrated.
- **MCP client**: connect external servers over stdio / Streamable HTTP; reads
  `[[plugins]]` and a Claude-Code `.mcp.json`.
- **Code intelligence via CodeGraph**: a tree-sitter symbol/call graph
  (`codegraph_*` tools) replaces embedding semantic search — no embedding service
  or API cost. Fetched into a local cache on first use (or `reasonix codegraph
  install`) and indexed in the background, so installs and startup stay fast.
- **Plan mode** with evidence-backed step sign-off (`complete_step`).
- **Memory**: `REASONIX.md` hierarchy + auto-memory, folded into the cache-stable
  prefix.
- **ACP** (`reasonix acp`) and an HTTP/SSE server frontend; desktop app (Wails).

### Notes

- Versions: the legacy TypeScript line stays in `0.x`; the Go line starts at
  `1.0.0`. See [docs/MIGRATING.md](docs/MIGRATING.md).
- Release archives ship a bare binary; CodeGraph is fetched on first use. Windows
  support for the fetched runtime is unverified — install `codegraph` on PATH if
  the auto-fetch doesn't resolve there.
