This makes it easier for downstream projects (forks) to replace the version fetching system with their own. It is as simple as implementing an interface and overriding the default implementation of org.bukkit.UnsafeValues#getVersionFetcher() It also makes it easier for us to organize things like the version history feature. Lastly I have updated the paper implementation to check against the site API rather than against jenkins.

Subject: [PATCH] Handle Excessive Signs in Chunks creating too large of
|
|
packets
|
|
|
|
Also adds a limit to stop sending Sign data to client after 500
|
|
signs per chunk to limit client lag.
|
|
|
|
Use -DPaper.excessiveSignsLimit=500 to configure that limit, or -1
|
|
to disable the limit and let your players be abused.
