Changelog

2.4.4

This release contains important fixes and we strongly encourage everyone to upgrade.

  • Fixed a memory leak in quic-go between 2.4.2 and 2.4.3
  • Added a new GET /online endpoint to the traffic stats API for retrieving current online users and their connection counts
  • The client now gracefully closes the QUIC connection when exiting

2.4.3

This release contains important fixes and we strongly encourage everyone to upgrade.

  • Fixed a bug introduced in the previous version that caused UDP forwarding to not work properly

2.4.2

  • Small tweaks to Brutal congestion control to improve performance at high speeds
  • When using a local certificate, the server now checks if the files can be accessed on startup. This ensures that access problems are detected immediately, rather than when accepting client connections.
  • Updated quic-go to v0.43.0

2.4.1

  • The client now supports listening to both HTTP and SOCKS5 on a single port by making their listen addresses the same
  • The client has added a new sockopts section to quic which allows the user to specify the bind interface, fwmark and FD control socket path for outbound QUIC connections. This is a feature mainly for Android app development.

2.4.0

  • Added TUN mode to client (supports Windows, Linux & macOS)
  • ACL now supports matching port ranges (e.g. reject(all, udp/40000-50000))
  • Added a listenHost field to the server ACME config to allow specifying the listening address for receiving validation requests
  • Updated quic-go to v0.42.0
  • Lowered the log level for proxied connection errors from error to warning

2.3.0

  • Added a built-in speed test subcommand for client & its server-side support
  • Automatically try to re-download GeoIP/GeoSite DB files if they fail to load
  • Better SOCKS5 outbound error messages
  • Fixed a bug where the dual stack listen address was actually only listening for IPv6 on FreeBSD

2.2.4

This release contains important fixes and we strongly encourage everyone to upgrade.

  • [Important] Fixed a bug where a connection timeout would block other connections from being established
  • Updated quic-go to v0.41.0

2.2.3

  • Fixed a bug where using an IPv4/IPv6 specific listening address like 0.0.0.0:443 or [::]:443 would still result in listening on both IPv4/IPv6
  • Delay server address DNS resolution until connection attempt when lazy mode is enabled
  • Local TLS certificates are now read every time a TLS handshake takes place, allowing users to update files without restarting the server

2.2.2

  • Fixed a bug introduced in the previous version that broke the automatic reconnection of the client
  • Added suffix: support to ACL for matching a domain and all its subdomains (e.g. reject(suffix:baidu.com))

2.2.1

  • Added GeoIP & GeoSite auto update (geoUpdateInterval field under ACL, default is 1 week)
  • Client now shows handshake information after connecting to the server, currently includes UDP forwarding availability & tx rate
  • Changed the basis for bandwidth conversion (Kbps/Mbps/Gbps/Tbps) from 1024 to 1000
  • Added RISC-V (riscv64) support
  • Updated quic-go to v0.40.0

2.2.0

  • Added GeoSite support to ACL (both GeoIP and GeoSite now use the v2ray "dat" format database)
  • Added support for non-English domains (IDN) to ACL (e.g. v6_only(战狼*.中国))
  • Added WebSocket support to masquerade proxy mode
  • Added secret-based authentication to Traffic Stats API
  • Fixed compatibility issues on certain Linux systems

2.1.1

This release contains important fixes and we strongly encourage everyone to upgrade.

  • Fixed a bug where a specially crafted UDP message packet could cause the server to crash
  • Fixed compatibility issues on FreeBSD
  • Windows users can now launch directly by double-clicking the exe file

2.1.0

  • Fixed a memory leak in BBR
  • Minor tweaks to Brutal congestion control
  • Added string mode to masquerade
  • Added HTTP/HTTPS proxy outbound

2.0.4

  • Optimized and fixed some issues in Brutal CC
  • Fixed problem where BBR could freeze the connection and cause CPU usage to spike under certain conditions
  • Fixed two race condition issues
  • Added HYSTERIA_BRUTAL_DEBUG environment variable. When enabled, it prints information like current RTT, packet loss, MTU, etc.

2.0.3

This release contains important fixes and we strongly encourage everyone to upgrade.

  • [Important] Fixed the problem where when using BBR (either the client doesn't set bandwidth or the server has ignoreClientBandwidth enabled), due to a bug in the BBR implementation, it could not accurately determine the bandwidth and send packets much faster than the limit.
  • Fixed the problem where ZeroSSL couldn't acquire certificates due to missing EAB.

2.0.2

  • Fixed connection issues on some devices due to lack of GSO support
  • Added HTTP/HTTPS (TCP) masquerade servers
  • Added Android builds

  • Added TCP redirect mode
  • Log HTTP requests handled by masquerade (debug level)
  • Added environment variable HYSTERIA_ACME_DIR to control ACME data directory location
