Minecraft 26.1 Pre-Release 2 MotD Limits for Hosts

Mojang has deployed the Minecraft 26.1 pre release 2 testing build, bringing server-side text component caps alongside parity adjustments and bug repairs tied to the Tiny Takeover game drop.

Server administrators testing prospective deployments on the Minecraft Server List or monitoring development builds for Minecraft 26.1 servers need to track how these changes impact server status pings, villager trading halls, and mob retention.

Server Text Components and MotD Handling

The primary technical adjustment in 26.1 Pre-Release 2 involves incoming and outgoing text formatting for the multiplayer ping list.

MotD Nesting Cap

Mojang has introduced a strict hard limit on text components used inside server status messages. Any MotD component nested beyond 16 levels will now be truncated, discarded by the client engine, and substituted with an ellipsis. Hosts using advanced custom JSON formatting, complex colour gradient tools, or layered translation components in their server descriptions must audit their raw status payloads to ensure text displays properly rather than cutting off.

Value Provider Tick Execution

A low-level issue tracked under MC-306814 has been fixed. Previously, environment_attribute value providers returned invalid results upon subsequent evaluations during the identical game tick. Server data packs leveraging these attribute lookups will now compute consistent values across repeated tick passes.

Gameplay Parity and Trading Adjustments

Several mechanics were altered to align Java Edition with Bedrock Edition behaviour and correct villager economy progression.

Spear Dismounting Thresholds

Dismount velocity requirements for spears have been updated to match Bedrock Edition. Players engaging in mounted combat will experience dismount triggers at the same relative impact thresholds found on Bedrock platforms, standardising weapon balance across editions.

Master Librarian Trades

For worlds running the Villager Trade Rebalance experimental toggle, Mojang resolved bug MC-306709. Master Librarians will now offer three distinct trades, ensuring that an enchanted book offering is permanently guaranteed at the highest trading tier.

Mob Persistence and Lead Fixes

A substantial batch of fixes targets entities despawning unintentionally when leashed or tagged with persistence flags:

• Untamed cats secured to fence posts with leads no longer despawn (MC-248092).
• Hoglins and Zoglins attached to leads will no longer vanish (MC-303684 and MC-303685).
• Squids, glow squids, and dolphins attached to leads are now prevented from despawning (MC-303749 and MC-303750).
• Trader llamas retained via breeding or leashed to wandering traders will no longer despawn unexpectedly (MC-153831 and MC-274238).
• Trapped skeleton horses possessing the PersistenceRequired tag will no longer despawn (MC-181169).
• Unlocking baby animal aging with golden dandelions will no longer wipe the animal's persistence state (MC-306328).
• Ender dragons configured with a DragonDeathTime score of 200 or above will no longer remain permanently without disappearing (MC-306798).

What This Breaks or Requires for Server Hosts

Administrators adopting 26.1 Pre-Release 2 do not need to perform immediate world format conversions, but specific configurations warrant verification:

• Review server list ping scripts: If your network relies on BungeeCord, Velocity, or custom plugins to render deeply nested MotD formatting, check if components exceed 16 layers. Anything beyond that depth will now automatically be replaced by an ellipsis on the multiplayer menu.
• Verify stasis chambers and pearl networks: Bug MC-304446, which deleted ender pearls whenever a stasis chamber was activated using a sponge, has been patched out. Redstone systems relying on pearl stasis can safely use sponge triggers again.
• Data pack evaluations: Data packs utilising environment_attribute providers should be tested to confirm multi-read calculations behave as intended within single ticks.
• Compatibility notices: The patch notes provide no details regarding third-party plugin API or mod loader stability; hosts should wait for compatible testing builds of their chosen server software before upgrading live environments.

What Players Will Notice

Players connecting to an updated server will immediately spot several visual and client-side changes:

• Exclusive Fullscreen option: A new toggle named "Exclusive Fullscreen" appears under display options. It defaults to off (non-exclusive borderless). Switching the toggle requires an entire game client restart to apply. Mojang notes that enabling exclusive mode may interfere with system Input Method Editors (IME).
• Visual mob scales: Baby cats have been scaled up to match the size of baby ocelots, and the baby horse model is no longer artificially scaled up (MC-306657).
• Swimming animations: The right hind leg of baby axolotls now animates correctly while swimming.
• Dolphin mechanics: Dolphins will no longer drown themselves when they have unobstructed access to air surfaces (MC-306658).

Communities running specialized servers such as Minecraft Cobblemon servers should continue tracking upstream release candidates before migrating their primary survival worlds.
