Helix 1.5.0

Helix 1.5.0 is a numbered private-LAN release. Keep it on a network you control. Public-internet exposure is not supported.

The dashboard Update Helix control uses these SHA-256-pinned source assets. It does not use git pull. Game containers are not replaced.

Changed

• Copying a server from AMP or Pterodactyl keeps it the same server. Helix reads
  the Minecraft version the world last ran from the server's own files (log,
  Paper version history, or version folders) instead of trusting panel
  settings, and refuses to install an older version or silently install the
  newest one over an existing world.
• A copy can keep its original game port, so players and router forwarding work
  unchanged. Helix allows it only when the stopped source instance is the sole
  owner of that port.
• Ports that plugins and mods open on their own — Simple Voice Chat, BlueMap,
  Dynmap, and Geyser — are read from their configs and opened on the new server.
  Any that are taken are listed with the reason instead of failing the copy.
• The copy dialog shows the version guard, the kept port, the add-on ports, and
  a finished summary with the address and what to do with the old instance.
• A port that another program already holds now says so, rather than only
  "already in use".

Fixed

• Copied server.properties no longer keeps a panel's server-ip, which bound
  to the host address and stopped the server starting inside its container.
• Custom JAR copies use the Java version their Minecraft version needs instead
  of always Java 21.
