+- mkdocs is now configured correctly for the new project structure
+- JAX installation is now handled correctly for different configurations (CPU, CUDA, TPU)
+- Fixed a couple of bugs in 2D regularied_bc and kbc (Warp) that emerged after merging 2d and 3d kernels
+
+### Added
+
+- Added abstraction layer for boundary condition efficient encoding/decoding of auxiliary data
+- Added the capability to add profiles to boundary conditions
+- Added prepare_fields method to the Stepper class to allow for more automatic preparation of fields
