v0.1.0-rc.5

October Bus 0.1.0-rc.5 / npm 0.1.0-next.15

Native v0.1.0-rc.5 is built from source
8357265c1113b6c7f87fb11d87924ee122e97156. npm 0.1.0-next.15 is built from
dacaaae4b448088254b6276e3670e9f416891e50, which adds only a publication
metadata/documentation fix; runtime and SDK implementation are identical.
Both are prereleases. Protocol version remains 0.1.
The annotated native release tag has a GitHub-verified signature.

Changes since native rc.4

• Managed remote MCP sessions use mcp stdio --connection-file and native
  lifecycle hooks. Credentials stay in the controller-managed connection file,
  refresh between requests and expire or retire with the execution. Hook failures
  report sanitized errors without replaying an uncertain write.
• mcp check checks the actual JSON-RPC response. version --json reports runtime
  and protocol versions for installers.
• Hosted HTTPS MCP connections validate their gateway origin and execution
  credentials. Controller integration checks cover renewal, hooks, human waits
  and retirement.
• npm distributes the TypeScript SDK and native CLI together for Linux, macOS
  and Windows on x64 and arm64. Exact-version native dependencies provide the
  executable; installing the CLI does not require Go.
• Managed SDK sessions require the runtime's session-retirement feature before
  registration. Upgrade the runtime together with the SDK; rc.4 does not support
  this contract.

Installation

For local CLI use with Node 20 or newer:

npx @october-dev/october-bus@0.1.0-next.15 demo
npm install @october-dev/october-bus@0.1.0-next.15

Native users can install the appropriate 0.1.0-rc.5 archive from GitHub Releases
without Node. The release includes checksums, build attestations, SBOMs, a
standalone license and remote-bus-runtime.json. Desktop consumes the two Linux
archives and that manifest as a pinned bundle; publishing Bus does not update an
existing Desktop installation. See the integration instructions
for artifact verification and installation.

The npm version advances past the unpublished next.14 development bundle so
that a deployed helper built from that older source cannot be confused with this
release. Existing latest remains unchanged; use the explicit version or next.

Qualification boundary

The managed transport has automated Go race tests, actual Desktop Core transport
tests and a check using Saturday's connection-file writer. Those checks do not
establish live SSH/model qualification or a production cloud deployment. Issue
#126 still needs the consumer
artifact pin and the live-host checks after publication. Cloud WebSocket support
is not part of this release. This is not a stable 0.1 launch declaration.

Release verification

• Release preparation CI
• Native archive builds and platform smoke tests
• npm package builds, platform installation tests and provenance

Stable latest has not been promoted. Platform code signing/notarization is not claimed; the signed Git tag and build attestations establish source provenance.

October Bus v0.1.0-rc.2

October Bus v0.1.0-rc.2 is an early release candidate for local development and integration testing.

Highlights:

• Adds experimental configurations for Claude Code, Codex, Cursor Agent, and OpenCode.
• Improves MCP structured responses across hosts.
• Adds native archive checks before release publication.
• Publishes the TypeScript SDK as @october-dev/october-bus.

Verification:

• Six archives cover macOS, Linux, and Windows on amd64 and arm64.
• Native smoke tests passed on macOS arm64, Linux amd64, and Windows amd64.
• Every archive includes an SPDX SBOM and GitHub build attestation.
• checksums.txt contains SHA-256 checksums for every release asset.

The harness configurations are experimental and are not compatibility guarantees yet. Platform code signing and notarization are not included in this release candidate. APIs and protocol behavior may change before 1.0.

Full changelog

October Bus v0.1.0-rc.1

October Bus is an open communication and coordination layer for AI agents and harnesses. This is the first public runtime release candidate.

Included:

• Native local runtime for Windows, macOS, and Linux
• Durable SQLite messaging, receipts, requests, replies, shared tasks, dependencies, and human escalation
• Draft protocol 0.1 with HTTP and MCP interfaces
• Go and TypeScript clients
• Black-box local-runtime conformance tests
• Early configurations for Claude Code, Codex, Cursor, and OpenCode

The protocol, packages, and adapters are still pre-1.0 and may change. Harness configurations are experimental until current compatibility evidence is published.

Each platform archive includes the runtime, conformance runner, license, specification, and documentation. SHA-256 checksums, SPDX SBOMs, and GitHub build-provenance attestations are provided. Platform code signing and notarization are not included in this release candidate.
