Minecraft 1.21 was released today, for both Bedrock and Java platforms. Sandlot does support Java Edition 1.21. (updated June 16) Sandlot does support Bedrock 1.21.0. Once the plugins we use have been updated and tested, we'll enable users to connect with these versions as soon as possible. Will update this post as soon as we get things updated. Bedrock 1.21.0 is already here. Expect Java Edition 1.21 support to take a bit longer (likely 3-4 days). Server upgrades will come later. This means that, even once you can connect with the new versions, new features in 1.21 will not be available in individual Sandlot servers until that server has been upgraded to 1.21. 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 Edition 1.21 can now connect. 1.21 is now the preferred version to use when connecting to the Sandlot.
Just FYI, the Easy Survival map on website does not load in Firefox. The other maps do load just fine. Error message: "Web files are not matched with plugin version: All files need to be same version (3.7-SNAPSHOT-94 - try refreshing browser cache (shift-reload)"
