Hi Gazebo Community!

This week’s meeting was held on 2026-08-24T18:00:00Z and the following is a summary:

PMC Business

  • None

New agenda items

  • Avoid GitHub PR Stacks: The PMC recommends avoiding GitHub PR stacks (gh-stack) for now for all Gazebo committers due to an upstream bug (gh-stack#371) that produces malformed commit author attributions.
  • Deprecating FreeImage for Ubuntu 26.04 (Resolute) / Jetty: Because FreeImage is being deprecated across package managers (homebrew-simulation#3298), the team agreed to drop FreeImage from 26.04 Jetty debs (ogre-2.3-release#11), deploying first to nightly / Rotary builds.
  • Gazebo-M Naming Process: Screened candidate names on the namestorming sheet, filtering out candidates with trademark or spelling issues. Be on the look out for a public poll to choose the name of the next Gazebo release.
  • Pixi Environment Updates: Updating Pixi environment configurations to match Ubuntu Resolute for Gazebo Rotary (ros2#1834).
  • Bazel Maintenance Hand-off: Coordinating maintenance duties and Central Registry (BCR) access for Bazel build rules across repositories.

Updates

Buildfarm & Infrastructure

  • Buildfarm Status: No new buildfarm issues this week. Tracking open issues on the Dashboard including UNIT_Server timeout (gz-sim#3829) and ApplyLinkWrenchTestFixture flakiness (gz-sim#2727). Investigating a failed BuoyancyTest.UniformWorldMovement build on Rotary Resolute.

Testing & Continuous Integration

  • Bazel Test Flakiness CI: Added Bazel CI workflows (gz-math#820, gz-transport#939) to repeatedly run test suites and isolate flaky targets.
  • gz-transport Test & CLI Improvements:

Physics & Simulation

  • Dynamic Mesh Volume Calculation: Updated gz-sim to compute duck volume expectations directly from mesh geometry instead of a hardcoded constant (gz-sim#3912).
  • Centroid-Based Buoyancy: Updated gz-sim to apply buoyancy forces at the collision geometry centroid while properly respecting mesh scaling (gz-sim#3909).

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

The next Gazebo PMC meeting will be on 2026-08-31T18:00:00Z
