@@ -12,6 +12,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Add Nunley variant to germanium material library based on Nunley et al. 2016 data.
 - Add `PointDipole.sources_from_angles()` that constructs a list of `PointDipole` objects needed to emulate a dipole oriented at a user-provided set of polar and azimuthal angles.
 - Added `priority` parameter to `web.run()` and related functions to allow vGPU users to set task priority (1-10) in the queue.
+- `EMEFieldMonitor` now supports `interval_space`.
 
 ### Changed
 - Switched to an analytical gradient calculation for spatially-varying pole-residue models (`CustomPoleResidue`).
