Features

Support for animated GIF server icons. Just drop a server-icon.gif file in the server root directory. Size limits are configurable. HodgePodge is a soft dependency, required if you want to use larger GIFs (because of the packet size limit). Use the /reload_icon command to reload the icon. Also works for server-icon.png.
Removal of EnderCore / HodgePodge Info Button in the mod list screen.
API to modify the S00PacketServerInfo packet. Example:

public class ClientProxy extends CommonProxy { @Override public void preInit(FMLPreInitializationEvent event) { S00PacketServerInfoModifyService.registerDeserializeHandler((response, fentlibData, serverData) -> { if (fentlibData.has("server_to_client_payload")) { // Yoohoo we got something back!!!! // serverData contains stuff like server IP } }); } } public class CommonProxy { public void preInit(FMLPreInitializationEvent event) { if (MiscUtil.isServer()) { S00PacketServerInfoModifyService.registerHandler((response, fentLibPresent) -> { // fentLibPresent is just a boolean indicating whether fentlib is loaded return "server_to_client_payload"; // You can return a String, a S00PacketServerInfoModifyService.KeyValue, or a JsonElement. If you return // a non-null value, it will be passed back to the client }); } } }

/dump_thaumonomicon <Optional Comment> command. Run it from the client, and all Thaumcraft research will be dumped as a static website. The comment will be visible under the page title, and you can indicate the pack or mods for with which the dump was done.
/warpdim [dimension ID] command. Painlessly warp to a dimension (meant for debugging).
SessionAccessTokenOverrideMixin allows overriding the session access token in dev launches via -Dfentlib.accessTokenOverride=<token>.
Client sound utilities to set a custom max attenuation distance without increasing the sound volume. Methods:

SoundUtil.withMaxDistance(ISound sound, float maxDistance); SoundUtil.playWithMaxDistance(ISound sound, float maxDistance); SoundUtil.playWithMaxDistance(SoundHandler soundHandler, ISound sound, float maxDistance); SoundUtil.playAt(ResourceLocation soundResource, double x, double y, double z, float volume, float pitch, float maxDistance);

Example:

SoundUtil.playAt(waveSound, x, y, z, 0.25F, 1.0F, 64.0F);

HTTP-on-Minecraft-port reverse proxying for local web UIs. Configure path-to-port mappings in config/fentlib/http-port-routes.json so services like Dynmap can be reached through the server port, such as /dynmap/..., instead of separate ports. Set publicBaseUrl in config/fentlib/fentlib.cfg to the public base URL of the server; mods should append their own relative route paths on top of it.
QOI image format support and utils thanks to saharNooby/qoi-java. For usage example, check out how support for server-icon.qoi is implemented.
WebP image format support and utils thanks to haraldk/TwelveMonkeys. For usage example, check out how support for server-icon.webp is implemented.
Default server icon path can be configured using the serverIconDirectory config option.

Fishing Loot Config

Set enableFishingLootTable=true in config/fentlib/fentlib.cfg to enable FentLib's fishing override. The loot table lives at config/fentlib/fishing-loot.json. When enabled, vanilla still decides whether a catch is fish, junk, or treasure, but the item itself comes only from this JSON.

The JSON has top-level fish, junk, and treasure lists. Each entry uses vanilla-style weight, supports count and meta ranges, can be limited to a biome whitelist with biomes or inverted into a blacklist with invertBiomes, and biome selectors can be numeric IDs, biome names, or * to match any biome. Entries can also use explicit numeric enchant IDs or useVanillaEnchantingRules for vanilla-style random enchanting.

{ "fish": [ { "item": "minecraft:fish", "weight": 60, "count": { "min": 1, "max": 1 }, "meta": { "min": 0, "max": 0 } }, { "item": "minecraft:fish", "weight": 10, "count": { "min": 1, "max": 2 }, "meta": { "min": 1, "max": 1 }, "biomes": ["ocean", "river"] } ] }
