Changed

• The chunk generation safeguard only acts while the server is also busy. Until now a single player exploring new land was enough to lower the view distance, even on an almost idle server. The safeguard now needs both: a high chunk rate and an MSPT of at least the new chunk-generation-safeguard.min-mspt (default 20). Set it to 0 for the old behaviour. Real overload is still handled by the normal MSPT limits.
• New bStats chart auto_update_enabled shows how many servers have the autoupdater on.
• Config template: the section header for density-based scaling stood above the wrong block. Fixed in config.yml and the README.

Config update

Existing config files get min-mspt: 20 added on the first start. Nothing else needs to change. If you want the old behaviour, set it to 0 and run /vdt reload.

Tested

Folia 1.21.11 with a bot teleporting into fresh terrain: with min-mspt: 1000 no terrain-generation decrease happened even with the chunk rate above the threshold, with min-mspt: 0 the decrease came right away. Reload without restart works. 248 automated tests. Not tested: the default of 20 under heavy generation load on a busy server.
