+### Changes in v1.4.1:
+
+-   Several cleanups and bug fixes
+    -   Improved precision of ray intersection with streamlines,
+        spheres, and cylinder geometries
+    -   Fixed address overflow in framebuffer, in practice image size is
+        now limited only by available memory
+    -   Fixed several deadlocks and race conditions
+    -   Fix shadow computation in SciVis renderer, objects behind light
+        sources do not occlude anymore
+    -   No more image jittering with MPI rendering when no accumulation
+        buffer is used
+-   Improved path tracer materials
+    -   Also support RGB `eta`/`k` for Metal
+    -   Added Alloy material, a "metal" with textured color
+-   Minimum required Embree version is now v2.15
+
