### Rayleigh 1.3.0

Rayleigh is a 3-D convection code designed for the study of dynamo behavior in spherical geometry. New to [v1.3.0](https://github.com/geodynamics/Rayleigh/releases/tag/v1.3.0):

- Coupled boundary conditions for different scalar fields
- CMake as an alternative to Rayleigh’s configure script
- Routines and notebooks for reading in checkpoint files

## Opportunities

### Nominations, CIG Director

As the end of the current phase of CIG approaches (January 31, 2028), CIG is soliciting nominations for the next Director to lead the next team and build on CIG’s leadership in computational geodynamics. Please see the [prior post](https://community.geodynamics.org/t/soliciting-nominations-for-the-next-cig-director/4540) for more details. The **deadline is July 15**.

### Program Committee

Join us in planning the next community meeting in **Summer 2027** in Santa Fe, NM. We are seeking your expertise in setting the program and engaging compelling speakers for our next get-together. Submit a [ticket](https://geodynamics.org/support/ticket/new) to volunteer and to contribute your suggestions for themes, topics, and tutorials.
