+# Blitzkrieg 1.15.10
+
+The 10th patch for the `1.15` update is here, breaking the record of the most patches for a single update!
+
+## Features
+
+- Added `/today`
+  - This is a direct alias for `/breakdown today`
+- Drastically simplified ratings command
+  - `/ratings current` and `/ratings archive` have been now merged
+  - Where the data is fetched from is now decided directly from the chosen season number
+- Simplified many error messages
+- Title bar description text is now centered when there is no image
+  - It always felt awkward when there was no image on the left but the left still aligned to the right
+- Removed `/link`'s requirement to select a username explicitly from the search results
+- Full names for regions are now used in the `/link` command
+  - So "NA" turns into "North America"
+
+## Fixes
+
+- Fixed contrast issues with WN8 percentile colors behind white text
+- Archived ratings neighbors now functions once again
