- do not log dial error twice
- DNS subserver shuts down without waiting for connections to finish (UDP server would hang sometimes)
- DNS over TLS dialer uses tls.Dialer instead of wrapping connection with tls.Client
- connection type is just `tls` instead of `dns over tls` to reduce repetition in logs
- exchange errors contain the request question in their context
- `PUBLICIP_API` accepts a comma separated list of ip data sources, where the first one is the base default one, and sources after it are backup sources used if we are rate limited.
- `PUBLICIP_API` defaults to `ipinfo,ifconfigco,ip2location,cloudflare` such that it now has `ifconfigco,ip2location,cloudflare` as backup ip data sources.
- `PUBLICIP_API_TOKEN` accepts a comma separated list of ip data source tokens, each corresponding by position to the APIs listed in `PUBLICIP_API`.
- logs ip data source when logging public ip information
- assume a rate limiting error is for 30 days (no persistence)
- ready for future live settings updates
- consider an ip data source no longer banned if the token changes
- keeps track of ban times when updating the list of fetchers
- remove Windows without WSL step
- update 'remote containers extension' to 'dev containers extension'
- remove invalid warning on directories creation
- simplify customizations section
- remove "publish a port" since it can be done at runtime now
- remove "run other services" since it's rather unneeded in this case
- expand documentation on custom welcome script and where to specify the bind mount
- use bullet points instead of subsections headings
- No point periodically fetch the public IP address. Could not find anything mentioning why this was added.
- Simplification of the publicip loop code
- `PUBLICIP_ENABLED` (on, off) can be set to enable or not public ip data fetching on VPN connection
- `PUBLICIP_PERIOD=0` still works to indicate to disable public ip fetching
- `PUBLICIP_PERIOD` != 0 means to enable public ip fetching
- Warnings logged when using `PUBLICIP_PERIOD`
- Faster start up
- Clearer error messages
- Allow for more Gluetun-specific customization
- DNSSEC validation is dropped for now (it's sort of unneeded)
- Fix#137
- Build API IP address using the first 2 bytes of the gateway IP and adding `128.1` to it
- API IP address is valid for both OpenVPN and Wireguard
- Fix#2320
- `STORAGE_FILEPATH=` disables storing to and reading from a local servers.json file
- `STORAGE_FILEPATH` defaults to `/gluetun/servers.json`
- Fix#2074
