v0.8.4-beta

## Email/IMAP Improvements
- Added fallback support for mail servers that don't support the ESEARCH extension. Libredesk now gracefully falls back to standard SEARCH when needed.

## Bug fixes
- Fixed outgoing conversation creation where selecting both team and agent cleared the agent assignment.
- Fixed layout shifts caused by large HTML tables in emails.

## Configuration
- You can now configure the app using [only environment variables](https://docs.libredesk.io/getting-started/installation#configuration-via-environment-variables).

## Upgrade
- Always take database backups before any upgrade.
- Follow steps [here](https://docs.libredesk.io/getting-started/upgrade).
