SideGate 1.2.1
SideGate 1.2.1

Release date: 2026-06-10

Added
  • Optional Floodgate and Geyser-Spigot integration. Detected Bedrock players stay on the Floodgate/Geyser authentication path and are not classified or tagged as SideGate guests.
  • Soft dependencies for floodgate and Geyser-Spigot; neither plugin is required when Bedrock support is not used.
  • Added configurable premium-session-failure.action with KICK_WITH_MESSAGE and FALLBACK_TO_GUEST modes.
  • Added a configurable Premium-name conflict message. SideGate compares the login UUID with the official Mojang profile before encryption so cracked launchers that abort on HTTP 401 receive the configured message.
  • Added Guest fallback for Premium-name UUID mismatches before encryption, plus same-connection fallback when an invalid encrypted session response is available.

Changed
  • Mojang profile lookups now run through ProtocolLib's asynchronous listener path to avoid blocking the packet thread.
  • Premium lookup cache entries now expire after 10 minutes and use bounded eviction instead of clearing the entire cache.
  • Premium lookup cache entries now retain the official Mojang UUID for early Premium-name conflict detection.
  • Mojang API errors, invalid responses, and invalid Java usernames now fail closed by leaving authentication to the server instead of granting guest access.
  • Guest connection selection now requires an exact address match or matching login profile name; unsafe cross-connection and port-only fallbacks were removed.
  • Removed the duplicate SideGate prefix from plugin logger messages because Bukkit already adds the plugin name.
  • Compatibility and issue-report startup notices now use INFO; the ProtocolLib dev-build warning is skipped when a development build is already installed.

Fixed
  • Fixed Floodgate/Geyser Bedrock players being treated as non-premium guests.
  • Fixed a possible guest injection mix-up when multiple login connections were pending.
  • Fixed a ProtocolLib TemporaryPlayer warning and stack trace caused by reading an unavailable UUID during early login.
