Hi Gazebo Community!

This week’s meeting was held on 2026-10-12T18:00:00Z and the following is a summary:

## PMC Business

- Approved Cherrie Lu for mentee committer status.
- Voting is currently open via email on adding Luca Della Vedova as a mentee PMC member.

## New agenda items

- **Gazebo Maintainer Audit & Rebalancing (Phase 2)**: A reminder that Phase 2 of the [Gazebo Maintainer Audit & Rebalancing Workspace (2026)](https://docs.google.com/spreadsheets/d/1Dk0cYyfQ-Ig1VztV74WaAkqRf-fdvgduxQHkhMWnfD4/edit?pli=1&gid=0#gid=0) (not public) is open through 2026-10-16T00:00:00Z. Committers interested in taking primary or secondary roles on packages can sign up in the spreadsheet before assignments are finalized and balanced across the team.
- **Homebrew Support Timeline** :
  - Gazebo Ionic reaches end-of-life in December, 2026.
  - Due to Homebrew’s scheduled removal of FreeImage on 2027-01-10T00:00:00Z ([homebrew-simulation#3298](https://github.com/osrf/homebrew-simulation/issues/3298)), Homebrew support for Gazebo Harmonic ([homebrew-simulation#3598](https://github.com/osrf/homebrew-simulation/pull/3598)) and Fortress ([homebrew-simulation#3597](https://github.com/osrf/homebrew-simulation/pull/3597)) will be dropped on the same date.
  - Qt5 support in Homebrew will also be dropped in May 2027. An announcement post will be drafted and shared on Discourse.

- **Review Policy for Prerelease Version Bumps** : Discussed streamlining the prerelease process by removing individual pull request review requirements for version bumps (such as Rotary prereleases). The agreed approach is to announce upcoming prereleases in advance with a short waiting window (up to 24 hours) before merging. Documentation will be updated to reflect this workflow.
- **Backport Policy & Downstream Testing** : Discussed guidelines for backporting multi-stage pull requests or features spanning multiple packages. While clean backports without conflicts can be merged directly, authors are encouraged to consider pausing backports until all related changes land on `main` and downstream continuous integration runs have completed.

## Updates

### Infrastructure & Buildfarm

- **macOS Tahoe Support** : A new macOS Tahoe runner (`mac-six.tahoe`) is online and operational. Tahoe bottling is underway ([homebrew-simulation#3592](https://github.com/osrf/homebrew-simulation/pull/3592)).
- **Python 3.15 Compatibility on Homebrew** : Formula test failures caused by the Python 3.15 rollout are being resolved with formula updates and bottle rebuilds for packages with Python bindings.
- **CI Optimization** : A pull request is in review to skip Linux CI PR jobs when changes only affect ignored files such as documentation, Bazel rules, or workflows ([release-tools#1558](https://github.com/gazebo-tooling/release-tools/pull/1558)).
- **Test Networking** : Merged [gz-sim#4047](https://github.com/gazebosim/gz-sim/pull/4047) to set `GZ_IP` across all test suites, preventing unintended multicast behavior.

### Simulation & Physics

- **Bullet-Featherstone Kinematics Mode** : Added kinematics mode improvements in `gz-physics`, fixing non-base link velocity calculations ([gz-physics#1112](https://github.com/gazebosim/gz-physics/pull/1112)) and supporting multi-link models ([gz-physics#1113](https://github.com/gazebosim/gz-physics/pull/1113)).
- **Thruster Test Stability** : Addressed intermittent thruster test failures by waiting for thruster commands before stepping simulation time, backported across branches ([Jetty](https://github.com/gazebosim/gz-sim/pull/4065), [Ionic](https://github.com/gazebosim/gz-sim/pull/4064), [Harmonic](https://github.com/gazebosim/gz-sim/pull/4063)).

### Rendering & Sensors

- **Image Constructor Cleanup** : Removed an unreleased raw pointer `Image` constructor in `gz-rendering` ([Rotary](https://github.com/gazebosim/gz-rendering/pull/1366), [Jetty](https://github.com/gazebosim/gz-rendering/pull/1367), [Ionic](https://github.com/gazebosim/gz-rendering/pull/1369), [Harmonic](https://github.com/gazebosim/gz-rendering/pull/1368)), resolving deprecation warnings in `CameraSensor` ([gz-sensors#675](https://github.com/gazebosim/gz-sensors/issues/675)).
- **Ogre 2.2 macOS Compatibility** : Patched `ogre2.2` for Xcode 16.3 compatibility ([homebrew-simulation#3591](https://github.com/osrf/homebrew-simulation/issues/3591)).
- **Sensor Test Scoping** : Updated `gz-sensors` to skip `CustomCameraInfoTopic` tests on render engines other than Ogre 2 ([Rotary](https://github.com/gazebosim/gz-sensors/pull/681), [Jetty](https://github.com/gazebosim/gz-sensors/pull/682), [Ionic](https://github.com/gazebosim/gz-sensors/pull/683)).

### Transport & Communication

- **Zenoh 1.8.0 Integration** : In-review backport to integrate Zenoh 1.8.0 into Gazebo Jetty ([gz-transport#977](https://github.com/gazebosim/gz-transport/pull/977)).
- **Publication Routing** : Merged changes to route Zenoh publications exclusively to other sessions ([Rotary](https://github.com/gazebosim/gz-transport/pull/961), [Jetty](https://github.com/gazebosim/gz-transport/pull/965)).

### Releases

- **Gazebo Rotary** : Completed the second prerelease of Gazebo Rotary.
- **gz-rendering** : Released 10.1.0 ([Jetty](https://github.com/gazebosim/gz-rendering/pull/1371)), 9.6.0 ([Ionic](https://github.com/gazebosim/gz-rendering/pull/1372)), 8.3.0 ([Harmonic](https://github.com/gazebosim/gz-rendering/pull/1373)), and 6.7.0 ([Fortress](https://github.com/gazebosim/gz-rendering/pull/1374)).
- **gz\_rendering\_vendor** : Released 0.4.5 ([Lyrical](https://github.com/gazebo-release/gz_rendering_vendor/pull/27)), 0.2.9 ([Kilted](https://github.com/gazebo-release/gz_rendering_vendor/pull/28)), and 0.0.8 ([Jazzy](https://github.com/gazebo-release/gz_rendering_vendor/pull/29)).
