- Fixed a critical security flaw that allowed attackers code on other's devices (RCE exploit). This can be done via in game messaging or other methods. The game logs a certain exploitable text as $jndi ://, because of an upstream vulnerability in the log.



Fog:



- The world fog now begins further away from players to make distant terrain easier to see. Fog is no longer applied as a spherical volume, but as a cylindrical volume.



Additions



Music Disc - Lena Raine has added a new music disc titled "otherside". - Found in rare cases in stronghold corridor chests and much less frequently in dungeon boxes. The disc's ring has a blue-green color.



The world generation:



Caves – Completely renovated. Now you can see Y=-59. - The caves now generate in 2 layers of different stone bases depending on the depth. - The layer above the Y=8 mark is made of regular stone. From Y=8 up to Y=0, stone transitions to deepslate. - Deepslate completely replaces stone from Y=0 to bedrock. Deepslate is still able to generate certain types and structures as well as tuff, gravel and other ores. - Dirt, diorite, granite and andesite do not generate in this layer.



- Aquifers below Y=0 sometimes generate with lava instead of water.



Cheese caves have large towers of stone that stretch from the bottom to top of the cave. These towers can be used to safely fly elytra. Spaghetti Caves are long, narrow caves with small aquifers. They are more like original caves. Noodle caves are thinner and more claustrophobic versions of spaghetti caves.



- Come in 6 sub-biomes: - Meadow - A grassy elevated biome that looks like a flowery and colder plains, with an aqua grass color and dark blue water color.

- Found in plateaus and the lower layers of some mountain peaks, often near plains or other temperate biomes. - Contains grass, tall grass, dandelions, azure bluets, cornflowers, poppies, daisies and alliums - Birch and oak trees can rarely appear in this biome, and always have bee nests. - Only rabbits, donkeys, and sheep spawn in this biome. - Plains villages and pillager outposts can generate in this biome.

- When surrounded by forested biomes, generates on the slopes a snowy mountain. It is reminiscent of a snowy Taiga, but with a snow-block and powder snow surface instead of grass blocks. This biome is home for wolves, rabbits, foxes sheep, pigs chickens and cows. This biome can also be used to generate pillar outposts.



- Produces snow on the slopes of a mountain, when it is not in plains or snowy tundra. - Covered in snow, snow block and powder snow. This biome can only be spawned by rabbits or goats. This biome is suitable for generating igloos or pillager outposts.



- One of the three biomes that create in the mountain peaks. - A covered in snow, snow blocks, and stones. - Can produce sharp and jagged peaks when there are snowy, cold and temperate biomes. This biome is home to only goats. This biome is suitable for generating pilgrouts.



- One of the three biomes that create in the mountain peaks. - Covered in snow, snow blocks, ice, and packed ice. - Generally generates smoother and more rounded peaks in areas that have cold, snowy, or temperate biomes. - Only goats spawn in this biome. This biome is suitable for generating pillar outposts.



- One biome that generates in the mountain tops. - Covered in stone, gravel, and strips of calcite. To avoid temperature clashes, the peak tends to generate in areas that are surrounded with warm biomes like jungles and savannas. - No animals spawn in this biome. - Pillager outposts can generate in this biome.



- Long and rare ore formations. Copper ore veins containing granite and blocks containing raw copper produce a higher Y=0. - Iron ore veins containing tuff and blocks containing raw iron generate below the Y=0.



Upgrading of old worlds



Terrain created from new chunks of terrain will now blend into existing terrain from previous chunks. These chunks will have any player-made structures intact, buried, and deteriorated. The old bedrock layer between the Y=0-Y=4 of old chunks is replaced with deepslate. - If there is any bedrock at Y=0, lower places under non-air block in old chunks will be generated by new world generation. - A new layer of bedrock is created at Y=-64.



Command format



/jfr



- When enabled, begins profiling with Java FlightRecorder, as well as the following custom events: - minecraft.ServerTickTime: Sampling event exposing average server tick times in intervals of a second - minecraft.ChunkGeneration: Time taken to generate individual chunk stages - minecraft.PacketRead / minecraft.PacketSent: Network traffic - minecraft.WorldLoadFinishedEvent: Initial world loading duration



- Advancements - Added four new advancements: - Caves & Cliffs - Fall from the top to the bottom of the Overworld.



Ride a strider on the lava for 50 blocks in Overworld



- Use a jukebox to play music in a meadow biome.



- Trade at the maximum build height limit with a villager



- Triggered when a player falls - ride_entity_in_lava. - Triggered every tick when a player rides in lava.



- Debug Screen - Added three lines: terrain, biome builder, multinoise. - Only appear if the dimension where the player is uses the multi-noise biome source type. Multinoise lists all parameters used at the position of the player to place a Biome. C is continentalness. E is erosion. T is temperature. H is humidity. W is weirdness. As you move further inland, your continentalness increases. Oceans can be generated in areas where there is low continentality. Erosion is a measure of how flat or mountainous a terrain is. Higher values mean flatter areas and lower values mean more mountainous terrain. The temperature and humidity have no effect on the terrain and only determine biome location. - Weirdness indirectly drives noise from the PV (peaks & valleys) and determines which variant of the biome is placed.



Font

"Left to Bloom", also known as the meadow and lush caverns biomes, is found in the menu screen. - "One More Day" plays in the meadow, snowy slopes and lush caves biomes, as well as the menu screen. "Wending", also known as "Wending", is played in the grove and jagged peaks, stony peak, and dripstone caves biomes. - "Infinite Amethyst", plays in the grove biomes as well as the menu screens.

However, the last two options could cause some visual delays in world update updates.



- Entities, blocks and fluids will not be updated outside of simulation distance. Allows for a greater render distance at a lower CPU load. - The lower limit is 5 chunks.
