net-merge 0.1.1

Install: download net-merge-setup-0.1.1.exe below and run it (needs admin; it upgrades an existing install in place). A portable zip is attached too. Not code-signed yet, so SmartScreen will warn: More info > Run anyway.

Added

• Speeds on hover. Hovering the tray icon shows each adapter's download/upload speed and a Total
  line. The numbers come from Windows' own adapter counters, so every app counts, including apps that
  bypass net-merge (qBittorrent binds to adapters directly), and they show while paused too.
• Real speeds in the menu. The right-click menu shows each adapter's speed, how many connections
  net-merge put on it, and whether it has IPv6.
• net-merge status shows each adapter's total traffic ("link") next to the part net-merge relayed.
• -mtu flag to change the virtual adapter's MTU (default 9000).
• -pprof flag to serve Go's profiler on a localhost address, for diagnosing CPU use.
• README: screenshots, features and how to use.

Changed

• About 3x less CPU. The virtual adapter now runs at MTU 9000 instead of 1500, so about 5x fewer
  packets go through the userland network stack. Measured on the same machine and links: 0.54 → 0.18
  CPU cores per 100 Mbit/s.
• Tray wording: Merging / Paused, and Pause merging / Start merging in the menu (was ON/OFF
  and Turn on / Turn off).
• Idle UDP sessions end after 30 seconds instead of 60, which means fewer sockets and less memory with
  torrent clients.
• Quieter log: torrent traffic no longer writes a warning for every dropped packet.

Fixed

• Tray icon missing after sign-in. With "start at sign-in" on, the tray could start before the
  taskbar existed and stay invisible and inactive. It now waits for the taskbar, and the sign-in task
  retries if the tray fails to start. If you enabled autostart in 0.1.0, install 0.1.1 with the option
  ticked to update it.
• UDP datagrams larger than 1500 bytes going through the virtual adapter were silently dropped.
• Tooltip cut off after "Ethernet 4 ↓": Windows 11 shows only 64 characters of a tray tooltip, so the
  text now fits that limit.
• A garbled "…" appeared when long tooltip text was shortened.
• Errors from the tray library were not written to the log in the windowless build.

net-merge 0.1.0

Install: download net-merge-setup-0.1.0.exe below and run it (needs admin; it upgrades an existing install in place). A portable zip is attached too. Not code-signed yet, so SmartScreen will warn: More info > Run anyway.

First release.

Added

• System-wide per-connection balancing: every new TCP and UDP connection, IPv4 and IPv6, is pinned to
  one adapter, so parallel connections use Wi-Fi, Ethernet and phone/USB tethers at the same time.
• Tray app: left-click turns it on or off, right-click shows per-adapter speeds, optional start at
  sign-in without a UAC prompt.
• Automatic adapter detection: real hardware with a default gateway is used, while VPN and virtual adapters
  (Tailscale, WireGuard, Hyper-V, WSL) are skipped; net-merge list shows why.
• Per-adapter internet checks: a link without internet gets no connections until it recovers.
• Connections are spread by each adapter's measured speed, separately for IPv4 and IPv6.
• IPv6 policy (-ipv6 auto|on|off): when only some adapters have IPv6, apps are steered to IPv4 so
  every adapter stays in use.
• Crash-safe: the virtual adapter and its routes disappear with the process.
• Command line: on, off, quit, status, list, autostart, cleanup, plus a SOCKS5 mode
  that needs no admin.
• Installer and portable zip.
