The standard behaviour for master is that it uses the release/version number rather than the latest master. This is designed to prevent modules "version mixing" e.g alerts.sh being on v20.4.0 and alerts_discord.sh being v20.5.0. Version mixing can cause unpredictable behaviour and break installs.
This solution will ensure that only the official the GameServerManagers repo uses this method. This allows forked repos to use custom code in master ignoring the release.
Removes a long time annoyance for any users who have servers with multiple IP addresses.
Now if the server has more than one IP address LinuxGSM will automatically try query all IP's until it gets a response.
The default IP in settings will now be 0.0.0.0 this also helps resolve issues with source servers and LAN browser #2534
If required it is still possible to manually enter the IP address you want to use. Also, displayip setting is useful if you want your alert to specify an IP address
IP variables for reference
ip the default IP for the server if using 0.0.0.0 LinuxGSM will query all available IP addresses
queryips a list of the ip addresses that will be queried
queryip the ip address that is being queried
displayip the ip/hostname you want to show up in alerts. if unset the internet-facing IP will be used
extip the external internet-facing IP address
This update is a major refactor of how LinuxGSM updates itself.
* will now use a version tag if downloading module for the first time.
* added backup repo (Bitbucket) that will be used if Github is unavailable.
* added ./gameserver and module version comparison this will allow instances to be correctly updated if there is a version mismatch.
* UI changes when modules are fetched for the first time
* added sessionname to fix broken tmux session is ./gameserver is called ./gameserver.sh
* change apt to apt-get as recommended by the apt packages when dealing with scripts.
* improvements to steamclient.so fix
* added fix to install inconsistent location across distros
* added dev/null for master server
* XDG_DATA_HOME
* prevent check_last_update from restarting server if stopped
