# HarnessLink 17.5.87 release notes

4 changes, released Oct 26, 2026.

### Added

- The home page's "Works with" row shows each supported harness's logo beside its name (Claude Code, Codex, omp, pi, Antigravity, Cursor), in one colour that follows the theme and in the harness's own colour on hover or focus; each still links to its page, and the /harnesses cards carry the same marks. A quieter "Also connects to" row lists the coding agents and editors that can use HarnessLink today through its MCP server or as a base URL for the gateway (Gemini CLI, GitHub Copilot, Windsurf, Zed, Cline, Roo Code, Kilo Code, Continue, OpenCode, goose, Amp, Warp, DeepSeek Harness, Aider), each checked against the tool's own documentation, and ends at a new guide section, [Any MCP client or base URL](https://harnesslink.sh/docs/multi-harness#any-mcp-client-or-base-url), with `hnl mcp print`, the gateway's base URLs and how each tool connects. /harnesses mentions the same list.
- The home page moves a little: the headline, install command and screenshot rise into place on load, and the pillars and harness rows fade up as they scroll into view. It never hides content that has already been painted, the page is complete without JavaScript, the motion code loads only after the page has finished loading, and with reduced motion turned on in your system nothing moves and that code is never downloaded.

### Changed

- The site's top bar no longer links Releases; release notes stay in the footer.

### Fixed

- The installer's setup step crashed on some Macs (seen on an Intel iMac) with `EINVAL: invalid argument, kqueue`, so setup never started. The installer sent setup's output to `/dev/tty`, which Bun cannot watch on older macOS kernels; it now leaves the output on the terminal it already has.
