v95.0.4638.54-3

• Fixed a crash on IPv6 URLs, e.g. https://[2001:db8::1] #236.
• Rename the option --concurrency to --insecure-concurrency and make it public, with the following documentation:

  --insecure-concurrency=<N>
  
    Use N concurrent tunnel connections to be more robust under bad network
    conditions. More connections make the tunneling easier to detect and less
    secure. This project strives for the strongest security against traffic
    analysis. Using it in an insecure way defeats its purpose.
  
    If you must use this, try N=2 first to see if it solves your issues.
    Strongly recommend against using more than 4 connections here.
