+## 4.6.0
+
+**Status:** In development
+
+The 4.6.0 release is a small release increment (so far).
+
+* **General:**
+ * **Optimization:** `-medium` search quality no longer tests 4 partition
+ encodings for block sizes between 25 and 83 texels. This improves
+ performance for a tiny drop in image quality.
+ * **Optimization:** `TUNE_MAX_PARTITIONING_CANDIDATES` reduced from 32 to 8
+ to reduce the size of stack allocated data structures. This causes a tiny
+ drop in image quality for the `-verythorough` and `-exhaustive` presets.
