Major Changes

Dimensions is now an ESM module. Source files have moved from src/node_modules to src
For backwards compatibility, the src/node_modules path is exported in the package.json and is also symlinked to the new location, best effort has been made to keep this compatible with existing extensions but there is the possibility of accidental breakages. New extensions should use ESM.
Configuration is now done via a YAML file in configuration/config.yaml this is the recommended approach for new configuration files or for deployment in k8s
Legacy config.js is still supported for backwards compatibility, but is not recommended for new deployments
Client IDs are now UUIDs instead of numbers - you can now use these as proper unique identifiers for that client's particular session
This project now uses pnpm instead of npm. To ensure the right dependencies are installed, please use pnpm install instead of npm install or if you do not have pnpm, you might be able to use corepack pnpm install

Features

Packet parsing now relies more on the terraria-packet dependency - this is just to unify our parsing into one implementation
Use packetfactory for buffer reader/writers - for anyone relying on dimensions for these, we recommend to move to use packetfactory as dimensions has
Blacklist now has hooks
Handlers for client/terrariaserver packets now get passed in PacketSource, this tells the extension whether the packet is directly from the client/server or whether it is from dimensions itself
