🐈 nanobot v0.1.4.post4 is here — 58 PRs merged, 29 new contributors, and a lot of real-world polish from the community.

This release is a big one: safer defaults, better multi-instance support, stronger MCP/tool reliability, and major improvements across Telegram, Feishu, QQ, DingTalk, Discord, WhatsApp, Matrix, and more. A ton of sharp edge cases got cleaned up in this cycle — the kind of fixes that make nanobot feel much more solid day to day.

Highlights

• Safer by default — Access control is tighter now. This release includes a real authorization-bypass fix and stronger default handling around allowFrom, making deployments much safer out of the box. (#1403, #1677)

• Multi-instance support is finally real — --config support landed, runtime path handling got cleaned up, and the CLI agent now supports --workspace / --config too. Running separate bots, tenants, or environments is much easier now. (#1581, #1635)

• MCP got tougher — SSE transport support is in, auto-detection is smarter, and MCP tool calls are much less likely to take down the process when cancellations or weird failures happen. (#1488, #1728)

• Tooling got more forgiving — Auto-casting tool params, safer validation, graceful datetime handling, and read_file size limits all help nanobot fail less badly when tools or inputs get weird. (#1610, #1507, #1508, #1511)

• Provider support keeps growing — Azure OpenAI support is here, Alibaba Cloud Coding Plan API support landed, prompt-caching affinity headers were added, and GitHub Copilot / Codex compatibility keeps improving. (#1618, #1563, #1428, #1555, #1637, #1525)

• Cron got much sturdier — External jobs.json changes are respected, job context handling is better, and cron jobs are no longer allowed to recursively schedule more cron jobs forever. (#1371, #1375, #1399, #1458)

• Context got cleaner — Consecutive user messages are merged to avoid provider-side errors, internal reasoning is hidden from user-facing progress updates, image MIME detection is more reliable, and prompt/platform guidance is more polished. (#1456, #1655, #1573, #1579)

• Telegram got a lot of love — Proxy handling was fixed, group topics are supported, /stop works better, streaming messages landed, and generic documents now keep the right file extensions. (#1535, #1476, #1482, #1660, #1522, #436)

• Feishu keeps getting better — Rich text parsing, table/card splitting, smarter format selection, Groq Whisper transcription, audio/video compatibility fixes, and cleaner event handling all landed in this release. (#1361, #1384, #1648, #1605, #1531, #1594, #332, #1568)

• More channels, more polish — DingTalk group chat support, QQ group handling and markdown sending, Discord group policy + attachments, WhatsApp media support, Slack fallback fixes, and Matrix media normalization all made it in. (#1467, #532, #1727, #553, #1613, #1638, #673, #1406)

• Cross-platform stability improved — Better Windows signal handling, fewer missing imports/dependencies, cleaner tests, and overall more confidence that nanobot behaves well across different environments. (#1598, #1485, #1533, #1546, #1339, #1521)
