Gazebo PMC Meeting Minutes 2026-11-09

Hi Gazebo Community!

This week’s meeting was held on 2026-11-09T19:00:00Z and the following is a summary:

PMC Business

Meeting Time Change: The PMC formally decided to change the weekly meeting time to 19:00 UTC due to daylight saving time (passed with 9 votes in favor).

Updated GenAI Guidance: Reviewed the updated GenAI contribution guidance, inspired by the ROS project’s AI-assisted contribution guidelines. AI use disclosure is now required in pull request descriptions (to help reviewers prioritize and approach reviews) and optional in individual commit messages, and the PR template will be updated accordingly. Contributors are also discouraged from dumping raw LLM-generated content to respect maintainers’ time.
Jenkins Server Upgrade: Upgraded the build.osrfoundation.org Jenkins instance with security patches, UI updates (such as relocated management buttons), and a build timeout plugin.
Tutorial Party Planning: Discussed preparations for the upcoming tutorial party on 2027-02-24T00:00:00Z to review documentation and filter out non-essential pages, with planning meetings to be scheduled in early January. Adding metadata tags to each tutorial document was suggested to distinguish static pages from those requiring testing or multiple reviews.

Fortress macOS ARM64 Crash & Support End of Life: Investigated a test crash in INTEGRATION_twoProcsPubSub (PubSubWrongTypesOnSubscription) on macOS arm64 in ign-transport11 (gz-transport#998). As noted in the early end-of-support announcement for Gazebo Harmonic and Fortress on macOS, macOS support and Homebrew formulas are scheduled to drop on 2027-01-10T00:00:00Z, and the team agreed to disable the crashing test on macOS to unblock Fortress.
Pixi Tool Migration to Python: Opened the first Python implementation of the Pixi Windows .bat scripts (release-tools#1583) for high-level design review as a step toward macOS support and shared cross-platform tooling across Windows, macOS, and Linux.

Vulkan Headless Support & Large Simulation Fixes: Updated ogre-2.3 packages with Vulkan headless support (ogre-2.3-release PRs), incorporating an upstream patch for a crash when running headless without a monitor. Also iterating on gz-gui patches (gz-gui#798) to fix a rendering race condition that previously caused issues when running large simulations such as the Jetty demo world and warehouse; this will be tested on other render backends and rebased against an overlapping shutdown serialization PR.
Depth Camera Near and Far Clipping Planes: Opened PRs in gz-rendering#1418 and gz-sensors#701 to support SDF //camera/depth/camera/near and far clipping planes. This enables simulating sensor dead zones (e.g., RealSense or Kinect) while moving clipping to the GPU to eliminate manual CPU-side data loops.

Dynamic Detachable Joint Plugin: Cleaned up and extended a community-contributed detachable joint plugin for attaching arbitrary objects at runtime (gz-sim#4185), adding fixes for startup, nested models, reset, and deletion. For the accompanying message update (gz-msgs#640), the team agreed to add a header field for future extensibility.
Convex Mesh Assertions (//mesh/@assert_convex): Opened PRs across sdformat#1736, gz-common#957, and Bullet-Featherstone in gz-physics#1146 so users can declare pre-decomposed convex meshes and skip convex decomposition checks on startup. The team also discussed opening an issue in gz-math to explore moving Mesh data structures to gz-math so they can be used in libsdformat.

As always, the meeting notes are available at Gazebo PMC meeting weekly agenda - Google Docs.

The next Gazebo PMC meeting will be on 2026-11-16T19:00:00Z
