This release brings comparability with 26.1 among some other changes.
Updated to 26.1/26.1.1
Separate Paper/Spigot jars are no longer needed
Likely to be compatible with future Minecraft versions now that obfuscation has been removed (hooray!)
Added support for the NoChatReports client mod by appending the field "preventsChatReports" to server status responses. This can be disabled in the configuration.
This update fixes a minor manifest issue in the spigot jar, where a paperweight manifest value would be mistakenly added. If you don't have any issues loading the jar, there is no need to update.
The 1.21.9 version is also compatible with 1.21.10
Fixed joining players getting kicked if someone has an expired keypair on their profile. This is achieved by making it seem as if the player isn't a real player and thus doesn't have a public key for chat reporting. As all players send system messages the client will have no idea that this is in fact a deception.
Added basic configuration to enable/disabled some features such as spoofing secure profile.
Added reload command for aforementioned configuration.
