# Changelog for chatmail deployment 

## untagged

- add guide to migrate chatmail to a new server
  ([#429](https://github.com/deltachat/chatmail/pull/429))

  ([#434](https://github.com/deltachat/chatmail/pull/434))

- query autoritative nameserver to bypass DNS cache
  ([#424](https://github.com/deltachat/chatmail/pull/424))

- add mtail support (new optional `mtail_address` ini value)
  This defines the address on which [`mtail`](https://google.github.io/mtail/)

  If you want to collect the metrics with Prometheus,
  setup a private network (e.g. WireGuard interface)
  and assign an IP address from this network to the host.
  If you do not plan to collect metrics,
  keep this setting unset.

  in a user's maildir.

- Require pyinfra V3 installed on the client side,
  run `./scripts/initenv.sh` to upgrade locally.
  ([#378](https://github.com/deltachat/chatmail/pull/378))

- don't hardcode "/home/vmail" paths but rather set them 
  once in the config object and use it everywhere else, 
  thereby also improving testability.  
  ([#351](https://github.com/deltachat/chatmail/pull/351))
  temporarily introduced obligatory "passdb_path" and "mailboxes_dir" 
  settings but they were removed/obsoleted in

  If it's an issue, a chatmail operator can still care to properly set reverse DNS. 
  ([#348](https://github.com/deltachat/chatmail/pull/348))

- Make DNS-checking faster and more interactive, run it fully during "cmdeploy run",
  also introducing a generic mechanism for rapid remote ssh-based python function execution.
