'''23w41a''' is the second [[Minecraft:snapshot]] for [[Minecraft:Java Edition 1.20.3]], released on October 11, 2023,<ref>{{snap|23w41a|October 11, 2023}}</ref> which adds [[Minecraft:Realms]] support for all versions, new functionality for [[Minecraft:decorated pot]]s, reintroduces function-related commands, improves command limits, and fixes bugs.

== Additions ==
=== General ===
'''[[Minecraft:Particles (Java Edition)|Particles]]'''
* Added new <code>dust_plume</code> particle type.

== Changes ==
=== Blocks ===
'''[[Minecraft:Decorated pot]]'''
* Now can store items, up to a single stack.
** [[Minecraft:Hopper]]s, [[Minecraft:minecart with hopper]]s and [[Minecraft:dropper]]s can now insert and/or extract items from them.
** [[Minecraft:Comparator]]s can now read the number of items in them.
** [[Minecraft:Player]]s can interact with them and insert items into them.
*** Player interactions cause pots to wobble and trigger a vibration frequency of 11.
** They have no GUI, and need to be broken to retrieve their content by players.
* Now can be smashed by projectiles, which cause them to shatter and drop their contents.
* Now can stack up to 64.

=== Non-mob entities ===
'''General'''
* The name of them is now shown if looked at and a <code>CustomName</code> is set, or always displayed if <code>CustomNameVisible</code> is set, similar to living entities.

=== Command format ===
'''[[Minecraft:Function (Java Edition)|Function]]'''
* {{cmd|function}} command has been changed to better accommodate new {{cmd|return}} command.
* Functions no longer have any result unless they use {{cmd|link=none|return}} or there was an error during lookup or instantiation.
** That means {{cmd|link=none|function}} command no longer returns (or even displays) the number of commands run during execution.
** Error conditions:
*** Calling non-existent function.
*** Calling empty function tag.
*** Macro instantiation failure.
* "Result" in this context means values that would be stored with {{cmd|execute store}}.
* The previous behavior where every command in a function would perform store if a function was called with {{cmd|link=none|execute store ... run ''function''}} is removed.
** That means that a single call to <code>''function''</code> stores at most once (zero times if {{cmd|link=none|return}} was not called).
** For function tags with multiple entries, function results are accumulated, but partial results are stored at the end of every function.
* Existing limits for functions have been refined to accommodate new execution rules and prevent a wider range of exploits:
** Limits apply even if run from command line (so it now always behaves as if they were placed in a function).
*** For example, all functions called by {{cmd|link=none|execute as @e run ''function''}} count towards the same limit.
*** Executions from command blocks still count as separate ones.
** Limit <code>maxCommandChainLength</code> for functions now counts "operations" like:
*** Execution of command for a single context.
*** Execution of a stage in {{cmd|link=none|execute}} (no matter how many contexts were modified).
*** Invocation of function.
** A new limit with game rule <code>maxCommandForkCount</code> now restricts the total amount of context that can be created by single state of functions like {{cmd|link=none|execute}}.
*** Example: if there are 5 entities in world, {{cmd|link=none|execute as @e}} creates 5 contexts, while {{cmd|link=none|execute as @e at @e}} creates 5*5 = 25 contexts.

'''{{cmd|execute}}'''
* Re-added <code>(if|unless) function</code> subcommand.
** A new execute sub-command that runs a function or function tag and matches the return value(s). If a tag is given, all functions run regardless of the results of prior functions.
** Syntax: {{cmd|link=none|execute (if{{!}}unless) function <function> -> [''execute'']}}
** Arguments:
*** <code>function</code>: The function or tag to run.
** The matching of the result value of the function(s) that run:
*** At least one of the functions must succeed for the match to succeed.
*** A successful call is defined as a function that:
**** Uses the {{cmd|link=none|return}} command to return a value.
**** The return value is not 0.
*** If no functions exited with {{cmd|link=none|return}}, neither <code>if</code> nor <code>unless</code> runs.

'''{{cmd|return}}'''
* Re-added <code>run</code> subcommand: {{cmd|link=none|return run <command>}}.
** This takes the result value from running the specified <code>command</code> and returns that as the return value of the function.
*** If command did not return any value (like, for example, call to a function without {{cmd|link=none|return}}), {{cmd|link=none|return}} doesn't execute and function continues execution.
*** If the given command fails, the return value is <code>0</code>.
*** In all other aspects, it works like {{cmd|link=none|return}} with a specified <code>return</code> value.
*** In case of fork (for example {{cmd|link=none|return run execute as @e run ''some_command''}}), the first execution of the command returns.
**** If there are no executions (for example in {{cmd|link=none|return run execute if @e[''something_impossible''] run ''some_command''}}), function doesn't return and continues execution.

=== General ===
'''[[Minecraft:Data pack]]'''
* The [[Minecraft:pack format]] version is now <code>20</code>.

'''[[Minecraft:Realms]]'''
* Are now available in snapshots, pre-releases, and release candidates.
** Any player who has an active Realms subscription is eligible to create a free snapshot realm.
** Snapshot realms are separate from the regular realms to prevent any issues from impacting regular realms.
* The version of the last played world on a realm is displayed in the realms list.
* Experiments are available for newly created worlds.
