This release moves the code to TypeScript and addresses various issues with the 1.x version. It also brings new features:

• Ask the bot to create images using using Dall-E (can be disabled via environment variables)
• The bot now knows the names of the chat participants
• The bot can be instructed to stop responding (tell it to go away or stop listening)
• There is a first implementation of context awareness that let's you ask the bot to summarize or take a look at older messages. This will dynamically fetch a larger or subset context for the bot.
