New versions of both Bedrock and Java platforms were released today (June 17): Sandlot does support Java Edition 1.21.6. (updated June 21) Sandlot does support Bedrock 1.21.90. Once the plugins we use have been updated and tested, we will enable users to connect with these versions as soon as possible. We will update this post as soon as we get things updated. Bedrock 1.21.90 support is available immediately. Expect Java Edition 1.21.6 support to take a bit longer (likely up to a week). Server upgrades will come later. This means that, even once you can connect with the new versions, new features in 1.21.6 / 1.21.90 (the "Chase The Skies" game drop) will not be available in individual Sandlot servers until that server has been upgraded to 1.21.6. If you have questions about which version a specific Sandlot server is running, please check out https://www.sandlotminecraft.com/th...s-the-sandlot-using-a-small-help-guide.35045/ which is graciously maintained by @GrassPelt
Java 1.21.6 is now able to connect. Java 1.21.4 and Java 1.21.6 are now the supported Java client versions. Always prefer latest.
