### New Features
* Easily switch to the latest version of the Chat Instructions prompt
provided by PingPong under Advanced Options, after setting a custom
prompt or creating an assistant with a previous default prompt. To
ensure continuity of assistant behavior, PingPong does not alter
assistant or thread prompts after they have been configured or created
respectively.
### Updates & Improvements
* Updates to the default Chat Instructions so the assistant better
avoids spoilers, only uses content students have already reached, and
keeps answers concise and spoken-friendly.
