Pretty big changelog, as it's been a while since we did a release. 😁 Some of the most important changes:

• We now support a whole bunch of different backends. (TGI, SageMaker, llama.cpp and all OpenAI compatible backends)
• We added support for more search providers (we now support SerpApi, serper.dev, SerpStack, You.com, and no search provider at all by parsing search results directly!)
• We added support for multi-sessions for users
• We added a new redesigned settings menu!
• We added new chat-ui and chat-ui-db docker images that you can run directly from GHCR
• And a lot of QoL changes and bugfix, feel free to read the changelog for more.

I'll split up future releases into smaller chunks to make it easier to parse the changes, this was the big one!
