Hi! I’m trying to upgrade mitmproxy from 0.18.2 to 2.0.2. This is my old configuration file (`~/.mitmproxy/mitmproxy.conf`):

```ini
transparent = true
host = true
script = [/opt/mitm/scripts/test.py]
ignore = [1.2.3.4]

```

Using [https://github.com/mitmproxy/mitmproxy/blob/master/mitmproxy/options.py](https://github.com/mitmproxy/mitmproxy/blob/master/mitmproxy/options.py) as a reference, I wrote this configuration file for 2.0.2 (`~/.mitmproxy/config.yaml`):

```auto
mode: transparent
showhost: true
scripts: [/opt/mitm/scripts/test.py]
ignore_hosts: [1.2.3.4]

```

But the `mode` and `showhost` settings appear to be ignored. With 0.18.2, I could just stick the equivalent settings in the config file, and drop the `-T --host` options when launching mitmproxy. This does not work for me on 2.0.2. If I launch it with `-T`, proxying works, but the `showhost` option is still not enabled. What am I doing wrong, how do I fix it?

Hi @secretpow!

Sorry for the trouble - we had a bug in this in 2.0 ([https://github.com/mitmproxy/mitmproxy/issues/1899](https://github.com/mitmproxy/mitmproxy/issues/1899)), this should be fixed with the next release.
