'''26.4 Snapshot 1''' (known as '''26.4-snapshot-1''' in the [[Minecraft:launcher]]) is the first snapshot for [[Minecraft:Java Edition 26.4]], released on September 22, 2026,<ref>{{Mcnet|minecraft-26-4-snapshot-1|Minecraft 26.4 Snapshot 1|September 22, 2026}}</ref> which makes minor changes and fixes bugs.

== Additions ==
=== General ===
'''[[Minecraft:Tag (Java Edition)|Tags]]'''
* Added the {{cd|#generated_in_below_zero_retrogen}} biome tag.
** Contains biomes to generate below worlds that predate [[Minecraft:Caves & Cliffs]].
* Added the {{cd|#is_cave}} collection tag.

== Changes ==
=== Blocks ===
'''[[Minecraft:Red mushroom]] and [[Minecraft:brown mushroom]]'''
* Can now be placed on any block with a top solid face regardless of lighting conditions.
** They still cannot spread unless the brightness at the new growth is less than 13, or its support block overrides light requirements, like [[Minecraft:mycelium]].

=== Command format ===
'''{{cmd|fillbiome}}'''
* Will now fill biomes with block accuracy.

'''General'''
* NBT conversion from floating point types to integer types now always converts to the closest possible valid number after rounding down.

=== General ===
'''[[Minecraft:Data pack]]'''
* The [[Minecraft:pack format]] version is now {{cd|122.0}}.
* Entries for different biomes in multi-noise biome sources can no longer overlap across all noise parameters with the same offset.

'''Dedicated server properties'''
* Added {{cd|allowed-connection-ids}}
** A list of comma-separted ids.
** If non-empty, the server will match the values against {{cd|_id}} property in {{cd|minecraft:intent}} packet.
*** If there is no match, the server will reject the connection.
** This works both for both status and login connections, so any user connecting without the correct {{cd|_id}} in the server address will not see the status and will not be able to join the server.
* Added {{cd|status-contact-details}} field
** If non-empty, the value of this field will be sent in the {{cd|minecraft:status_response}} packet JSON payload under the contact property.
** This value is meant to be used to signal a way to contact the server owners about the server, even if there is no website or other information about it.
** This field is meant to be human-readable, but there are no other restrictions on field format.
* Added {{cd|enable-legacy-status}} field
** This option allows disabling existing legacy (pre-1.7) server status and ping protocol handling.
** To preserve existing functionality, value defaults to {{cd|true}}.
** Note: {{cd|enable-status}} needs to be set for any status information (modern or legacy) to be set.

'''Network protocol'''
* Added {{cd|minecraft:mod_list}} custom packet payload
** This packet is intended to inform servers about client mods to simplify debugging.
** Vanilla client sends an empty packet at the start of configuration phase, as it does not know about any mods – that is still a responsibility of 3rd-party modding platforms.

* Modified {{cd|minecraft:intention}} packet
** The {{cd|host}} field in the serverbound intention packet can now hold additional parameters (previously it stored only the domain name used for connecting to a server).
*** The new format is similar to URI query strings – the domain can now optionally be followed by a {{cd|?}} character and then followed by {{cd|key{{=}}value}} pairs separated by a {{cd|&}} character.
*** Empty values can be omitted (including {{cd|{{=}}}} sign).
*** Keys and values are escaped according to the standard URI rules ("percent-encoded component").
*** Keys starting with {{cd|_}} are reserved for vanilla use.
*** Users can now input properties in any "Server Address" field in the server list.
**** Additionally, any address in form of {{cd|<id>@<host>}} will be parsed as {{cd|<host>?_id{{=}}<id>}}
*** If a server uses SRV DNS records, the host field will contain both original and resolved domains.
**** If the resolved domain is different from the original domain, the resolved one will be used as the "primary" one, while the original one will be added as {{cd|_o}} ("origin") property.
**** Example host string: {{cd|redirected domain>?_o{{=}}<original domain>:<original port>}}, while the port field in the intention packet will be set to the resolved port value.
*** The field size has been extended to 1024 characters.
*** Note: since the {{cd|minecraft:intent}} packet is unencrypted, properties should not be used for any security-sensitive purpose.

* Modified {{cd|minecraft:transfer}} packet
** Added {{cd|properties}} field – a string to string map of properties that will be added to the host field in the {{cd|minecraft:intent}} packet sent to the target server.

'''Order-Independent Transparency shaders'''
* The OIT algorithm was simplified by replacing the wavelet-based mathematics with depth bin-based accumulation.
** Slightly improved performance at least on some devices.
** Reduced floating point precision issues on average.
** {{cd|OIT_WAVELET_RANK}} shader define was removed.
** {{cd|OIT_COEFF_COUNT}} shader define was replaced by {{cd|OIT_NUMBER_OF_DEPTH_BINS}}
** {{cd|OIT_COEFF_ATTACHMENT_COUNT}} shader define was renamed to {{cd|OIT_TRANSMITTANCE_TARGET_COUNT}}

'''[[Minecraft:Resource pack]]'''
* The version is now {{cd|98.0}}.

=== World generation ===
'''[[Minecraft:Configured feature|Features]]'''
* Changed {{cd|straight_trunk_placer}}
** Added the {{cd|trunk_width}} field.
*** Optional int provider, the width of the trunk centered around the origin.
**** Defaults to {{cd|1.0}}

'''[[Minecraft:Noise settings]]'''
* The {{cd|default_block}} field has been removed.
** This is now always {{cd|air}} – any other block should be defined by the [[Minecraft:material rule]].{{More info|Changing the default_block to air in previous versions causes a very different result; some change occurred in material rule.}}

'''[[Minecraft:Material rule#Surface conditions|Material conditions]]'''
* Updated {{cd|minecraft:steep}}
** No longer considers height modifications from eroded badlands "surface extensions" in an order-dependent way.

'''[[Minecraft:Placed feature]]s'''
* The possible domain in the XZ plane of placed features included in biomes is now validated.
** Feature placement can only occur within a 3×3 chunk region: as such, it is not valid for a Placed Feature to select a position outside of that range.
** Note: the size of the feature itself is not currently taken into consideration, which may still overflow the chunk.

'''[[Minecraft:Placed feature#Placement modifiers|Placement modifiers]]'''
* Changed {{cd|cuboid}}
** {{cd|xz_size}} and {{cd|y_size}} have been adjusted to represent the actual size of the cuboid, instead of implicitly being 1 block larger.
*** As such, an {{cd|xz_size}} of {{cd|2}} will actually produce a 2×2 cuboid instead of 3×3.
* Changed {{cd|fixed_placement}}
** {{cd|positions}} now requires at least one element.
