- Added support for argument passing to DRC file when running checks with `DRCRunner.run(..., drc_args={key: value})` in klayout plugin.
- Added support for `nonlinear_spec` in `CustomMedium` and `CustomDispersiveMedium`.
- `tidy3d.plugins.design.DesignSpace.run(..., fn_post=...)` now accepts a `priority` keyword to propagate vGPU queue priority to all automatically batched simulations.
- Introduced `BroadbandPulse` for exciting simulations across a wide frequency spectrum.

### Breaking Changes
- Edge singularity correction at PEC and lossy metal edges defaults to `True`.
