-# v0.4.4 RELEASE HIGHLIGHTS! 🚀
+# v0.4.5 RELEASE HIGHLIGHTS! 🚀
 # -----------------------------
-## GPT-4 is back!
-Following OpenAI's recent GPT-4 GA announcement, the SMART_LLM .env setting 
-now defaults to GPT-4, and Auto-GPT will use GPT-4 by default in its main loop.
+This release includes under-the-hood improvements and bug fixes, such as more 
+accurate token counts for OpenAI functions, faster CI builds, improved plugin 
+handling, and refactoring of the Config class for better maintainability.
 
-### !! High Costs Warning !! 💰💀🚨
-GPT-4 costs ~20x more than GPT-3.5-turbo. 
-Please take note of this before using SMART_LLM. You can use `--gpt3only` 
-or `--gpt4only` to force the use of GPT-3.5-turbo or GPT-4, respectively, 
-at runtime.
+We have also released some documentation updates, including:
 
-## Re-arch v1 preview release!
-We've released a preview version of the re-arch code, under `autogpt/core`.
