NoDPI v2.4-beta.1

Beta release

What's Changed

• This update significantly improves YouTube loading on providers where the DPI drops part of the connections to Google video servers (#101)
• Built-in DNS over HTTPS (DoH)
• Race ClientHello over parallel connections (can be disabled with --no-retry)
• Add connect, ClientHello and reply timeouts
• Add OOB desync method for ClientHello
• Skip hosts that keep failing for 5 min (can be disabled with --no-skip-dead-hosts)
• Use happy eyeballs for upstream connects
• Show fatal errors in quiet mode
• Less noise in the error log: client aborts before ClientHello are no longer logged, connection resets are logged as a single line
• Fix several old bugs in logging, connection handling and pipe encoding
• Split main.py into modules, enable ruff
• Add code of conduct and contributing guide
• Linux binary now runs on Ubuntu 20.04 and newer (glibc 2.17+)

New command line options

Option	Description
--no-doh	Use the system DNS instead of DNS over HTTPS
--doh-server URL	Own DoH resolver tried first, e.g. https://94.140.14.14/dns-query. Can be repeated
--no-retry	Do not retry the ClientHello over new connections when the server is silent
--no-skip-dead-hosts	Do not refuse connections to hosts that failed several times in a row

Note

A custom --doh-server must support HTTP/1.1. Some resolvers, such as Quad9, only work over HTTP/2 and will be skipped.
