Chunksmith

Added

• Your world can pre-generate itself before you start playing it. On a single-player world, Chunksmith now freezes the world on entry and pre-generates a 4096-block radius behind a progress screen, with a filling bar, a live estimate of the time remaining, and an Enter World Now button. Pressing it hands the world straight back to you -- it does not stop the run. Generation carries on in the background and yields to you from then on.

  Freezing does not make generation faster. It stops the world moving while it runs, so nothing ages, wanders off or starves while you wait.

  Once a world has finished, it never does this again. A completed run is recorded, so loading that world afterwards goes straight in. Leaving early with the button records nothing, so the next load simply continues where it stopped, and raising worldEnterPregenRadius asks for more world and starts it again.

  It works in a world created without cheats -- the settings are changed directly rather than through the command interpreter -- and everything it borrows is written down before it is touched, so a crash mid-freeze is put back on the next start rather than leaving your world frozen.

  On by default, MC 26+ on Fabric and NeoForge, single-player only. Turn it off with worldEnterPregen, or size it with worldEnterPregenRadius (default 4096). (mod_support #20)

Fixed

• An IPv6 address can now actually be set with /cs set. Quoting it -- the obvious thing to try once the bare form is refused by Minecraft's command parser -- used to fail too: the quotes were arriving as part of the value, so "2001:db8::1" was rejected as malformed. Both routes were closed on a setting whose whole job is naming an address. Quoted values now work everywhere, on every loader and the plugin. (Bare IPv6 still cannot work -- Minecraft's parser stops at the first colon -- so quote it: /cs set lodBackchannelHost "2001:db8::1".)

• Impossible addresses are refused instead of stored. 256.1.1.1 was accepted and kept: four numeric labels satisfy every ordinary hostname rule, so the setting held an address that could never resolve and the only symptom was a backchannel that quietly did not work. Also refused now: 1.1.1.999, 1.2.3, 1.2.3.4.5, 010.1.1.1 (a leading zero means octal to some resolvers and decimal to others) and example.123. Fully-qualified names ending in a dot, like example.com., are accepted -- they were being refused.

• 0.0.0.0 is no longer accepted as the address to advertise to clients. It is exactly right for lodBackchannelBindAddress (listen on every interface) and meaningless for lodBackchannelHost: a client told to connect to 0.0.0.0 has been told nothing. Leave that key empty if you want each client to use the address it connected on.

• A server whose hostname contains an underscore can now serve LOD over the backchannel. myserver_minecraft.example.com broke it in two places at once: the address was rejected outright by the config, so lodBackchannelHost silently reset to empty and could not be set at all; and the download itself failed on every region without ever falling back to the slower in-band channel, so it looked like the mod had simply stopped. Both are fixed -- such a host is now accepted, and the downloader resolves it and reports plainly in the log what it did. If a host genuinely cannot be reached, it now says so and falls back instead of going quiet. (mod_support #26, reported by arsenelupin0)

Removed

• The standalone Chunksmith-Client mod is gone -- the project has been retired and its repository deleted -- so everything that referenced it has come out: the chunksmithclient incompatibility declarations from the Fabric and NeoForge manifests, and the startup check that warned when both were installed.

  If you still have an old Chunksmith-Client jar installed, remove it. Chunksmith no longer refuses to start alongside it; both mods register the same chunksmith:lod channel, so having both is now a duplicate registration rather than a clear error message. Its multiplayer LOD job has been built into Chunksmith itself since 3.1.0 -- you lose nothing by deleting it.
