OpenHands/OpenHands (84,387 stars) released v1.14.0 on 2026-08-17. The headline changes are practical rather than architectural: the Canvas default model is now Kimi K3 and tagged free, LLM pre-flight validation blocks saving a misconfigured provider profile before it fails at runtime, and a Git Sync page lands in automations. Fixes cover preserving backend scope in conversation links, showing the full workspace file tree in the Files tab on cloud backends, and setting the local responder URL from browser origin. The free-default-model choice is the signal worth watching — a major open agent picking Kimi K3 as its no-cost onramp.
