+# Blitzkrieg 1.7.0
+
+This is mostly a technical update to make migrating to cyclic.sh easier.
+
+## Changes
+
+- The bot's new deferred caching approach allows the bot to start up almost `4x` as fast
+
+## Technical Changes
+
+- Made numerous caches non-blocking
+  - Removed an unnecessary root-blocking await where fonts are imported
+    - Further improved performance by deferring font imports until after the declaration
+  - Tank averages and tankopedia are now declared fully empty only to be populated after a deferred fetch
+- Reordered error handler, client login, and client event listener registration orders
+- Removed `vite` all together
+  - This reduces bundle sizes
+  - To do this, a more primitive way of importing commands is used
+- Removed the redundant usage of `args` to get the Discord token and Wargaming Application ID on each use
+- Added a build script using `esbuild`
