simstudioai/sim is a collaborative workspace for building, deploying, and monitoring AI agents and workflows. v0.9.39 is a release published on November 1, 2026. The changes include organization member pages and member info import. The release also carries a feature to continue desktop browser sign-in, a feature to keep waiting for answers while long tool runs continue, and a change to add documents to the resource library. This is the scope of this version as recorded in the release summary.
This project is a workspace that covers not only the creation of AI agents and workflows but also deployment and monitoring. The changes in v0.9.39 break down into pages and info import related to organization members, the desktop browser sign-in flow, the flow of waiting for answers during tool runs, and adding documents to the resource library. So what is visible in this release is not a change in agent performance but an update spanning several features of the workspace. The repository description introduces the project as a space used by more than 100,000 builders.
However, the provided release summary does not state the specific behavior or scope of each feature. It is not possible to tell what information the member info import handles, how continuing the sign-in works, or under what conditions the feature that waits for answers during long tool runs operates. No performance figures or accuracy changes are given either. So it is more accurate to read v0.9.39 as limited to the feature additions and changes stated in the summary.
