## Recent releases

| Version | Date | Urgency | Changes |
| --- | --- | --- | --- |
| `v1.1.7` | 2026-06-04 | High | Four new Bambu Lab printers, dry your filament right from Kiln, and clear a backed-up queue in one step — all free.  ### New - **Four more Bambu Lab printers** — the X1E, P2S, A2L, and the enclosed H2S. Recognized on connect: temperature limits, build volume, per-material settings, and a tuned slicer profile, no manual setup. - **AMS drying, free for everyone** — on Bambu printers with an AMS 2 Pro or AMS HT, start/stop a drying cycle and see how damp the filament is, time remaining, and the dry |
| `v1.1.5.2` | 2026-05-28 | High | **Kiln tells you when there's a new version** — whether you're working through an AI assistant or on the command line — and `kiln self-update` does the upgrade for you.  Full release notes: https://github.com/codeofaxel/Kiln/blob/main/CHANGELOG.md |
| `v1.1.4` | 2026-05-21 | High | Native Windows support — install Kiln, connect your AI agent, and generate designs on a stock Windows machine, with setup made easy. The release also sharpens overhang detection for cantilevers and islands, makes AMS Lite filament readings accurate, and puts safety messages in plain language.  ### Added  - **Native Windows support.**  The CLI, `kiln install-mcp`, and design   generation run on a stock Windows install.  The install page   (kiln3d.com/install) has a Windows walkthrough — Python se |
| `v1.1.3` | 2026-05-20 | High | **What's new in v1.1.3**  - **Free-tier design intelligence finds what you ask for.** Materials, design templates, printer profiles, BOSL2 + MCAD OpenSCAD libraries, and Bambu A1 print g-code now all ship in the PyPI wheel. - **Bridges read accurately now.** Curved arches don't get over-measured; the reported span matches what the slicer will print. - **Release gate** asserts data files ship in the wheel before any publish.  Full notes: see CHANGELOG.md |
| `v1.1.1` | 2026-05-13 | High | ## [1.1.1] - 2026-05-13  Vision event-name split, MCP-client config self-heal, an event-aware `watch_print_status` subscribe mode, and a few quality fixes.  ### Added  - `watch_print_status` `block_until_event` subscribe mode — agents can   await a specific event instead of polling. - `kiln health`: detects MCP-client config drift and self-heals stale   `kiln` command paths in Claude Desktop / Claude Code / Codex configs. - `kiln install-mcp`: richer installer promoted from kiln-pro. - `kiln ser |
| `v1.1.0` | 2026-05-06 | High | ## [1.1.0] - 2026-05-06  Design templates rebuild + automatic Pro+ calibration on every slice tool + safer pre-print validation gate + a self-service tier diagnostic.  ### Added  - **`check_my_tier` MCP tool** — answers "what plan am I on, and why" for   agents handling user questions about tier / subscription / paywall   confusion. Walks the live tier-resolution chain (env var → license   file → OAuth session → cached entitlement → free fallback) and   returns a plain-English summary the agent |
| `v1.0.0` | 2026-04-29 | High | ## What's Changed * Remove stale /demo fake-CLI assets; anchor Watch-the-demo link by @codeofaxel in https://github.com/codeofaxel/Kiln/pull/38 * build(deps): bump pytest-cov from 7.0.0 to 7.1.0 in /octoprint-cli by @dependabot[bot] in https://github.com/codeofaxel/Kiln/pull/26 * build(deps): bump attrs from 25.4.0 to 26.1.0 in /kiln by @dependabot[bot] in https://github.com/codeofaxel/Kiln/pull/25 * build(deps): bump pygments from 2.19.2 to 2.20.0 in /octoprint-cli by @dependabot[bot] in https: |
| `v0.5.0` | 2026-03-21 | Medium | ## Kiln 0.5.0  **"Describe it or draw it. Kiln makes it real."**  ### New Capabilities - Design Intelligence (52 materials, 20 patterns, 70 templates) - Printability Engine (7-dimension analysis with thermal stress) - Multi-Part Assembly (clearance, joints, tolerance, split planning) - Smart Cost Estimation (material/time/quality recommendations) - 14 built-in materials, adhesion force estimation  ### Infrastructure - kiln-pro: REST API, compat shims, 512 tests - 430+ MCP tools, 134 CLI commands |
| `v0.4.2` | 2026-03-19 | Low | ## What's New in v0.4.2  ### Highlights - **SDCP V3 Elegoo support** — HTTP push upload for Centauri Carbon with V2 fallback. Thanks [@bobbyhiddn](https://github.com/bobbyhiddn)! - **Multi-color multi-copy printing** — each copy gets a different AMS color - **Parametric design library** — 10 OpenSCAD modules (gears, threads, containers, lattice, etc.) - **MCP session greeting** — agents see the full capability map on connect - **did-you-mean CLI** — mistyped commands get suggestions - **3MF cost |
| `v0.4.1` | 2026-03-13 | Low | ## What's New  ### Material-Aware Reprinting - **5 new MCP tools** for switching materials mid-workflow: smart reprinting with automatic slicer re-configuration - **Multi-material printing** with AMS passthrough support - **Expanded material database** — 5 new materials with full safety profiles and compatibility data  ### Safety & Reliability - Material safety checks hardened: XML escaping, cross-brand compatibility warnings - Audit-driven corrections across the compatibility matrix and overrid |
