'''0.0.23a_01'''<ref>https://youtu.be/geoJG1cAFgM</ref> is a version of [[Java Edition Classic]] released on July 11, 2009,<ref name=change>[[wordofnotch:142033128|"Changing the version system"]] – [[The Word of Notch]], July 15, 2009</ref><ref>[[wordofnotch:140196422|"There are a lot of cool things like this on"]] – [[The Word of Notch]], July 12, 2009</ref> at 14:35 UTC.<ref>[[#logs|IRC logs]]: "''A9:34:54 <08Notch> ok, _01 will be up in a minute or two''" (14:34:54)</ref> It is the last version of [[Multiplayer Test]]. This version is not available in the launcher, but has been archived elsewhere.

== Changes ==
* Added a keymapping to control render distance.<ref>[[#logs|IRC logs]]: "''A9:32:05 <08Notch> moving it to an F-key, though [...] well, I could just make it mappable..''" (14:32:05 UTC)</ref>
** Players can once again press {{key|F}} to toggle render distance.<ref>[[#logs|IRC logs]]: "''A9:39:26 <CheeToS> yay, thank you for putting the f key back''" (14:39:26 UTC)</ref>

== Remake ==
{{main|Classic 0.0.23a_01 (remake)}}
To celebrate 10 years of ''Minecraft'', a JavaScript remake of this version was uploaded to the ''Minecraft'' website and made it possible to play multiplayer with up to 9 others through the browser. This version can be played at [https://classic.minecraft.net classic.minecraft.net].<ref name="classic.minecraft.net">{{Mcnet|embrace-past-minecraft-classic|Embrace the Past with Minecraft Classic|May 7, 2019|Tom Stone}}</ref>

== Trivia ==
* [[Notch]] planned to refactor the [[Version formats|version naming system]] after this version, removing the second zero and the "a", becoming the format "<''major version''>.<''release number''>[_<''patch number''>]". As an example, since this was the most recent version at the time, "0.0.23a_01" would be called "0.23_1" with such a system.<ref name=change/> However, this version was never actually given this name outside of this example.
** This format was also used somewhat in [[Java Edition Beta|Beta]].
