## [Unreleased]

### Added
- Added `symmetrize_mirror`, `symmetrize_rotation`, `symmetrize_diagonal` functions to the autograd plugin. They can be used for enforcing symmetries in topology optimization.
- Klayout plugin automatically finds klayout installation path at common locations.
- Added autograd support for `TriangleMesh`, allowing gradient computation with respect to mesh vertices for inverse design.
- Added `EMESimulation.store_coeffs` to store coefficients from the EME solver, including mode overlaps, interface S matrices, and effective propagation indices.
- Get cell-related information from violation markers in `DRCResults` and `DRCViolation` to the klayout plugin: Use for example `DRCResults.violations_by_cell` to group them.
- Added autograd support for `Sphere`.

I ran into a similar thing here in my custom vjp PR. Talking with @yaugenst-flex , I think they are going to open up schema breaking changes again Jan 5th. So the PR might need to wait to get merged until then
