BlueMapWebChat 4.7.0 · Minecraft 1.18–26.2 · Java 17 baseline

BlueMapWebChat is a server-side web chat plugin for Bukkit/Paper/Spigot-compatible Minecraft servers. It can run as a BlueMap addon, as a standalone web chat, or in both modes together.

4.7.0 highlights

• Conservative Minecraft support baseline expanded to 1.18 through 26.2 with Java 17 bytecode and api-version: '1.18'.
• Administrator custom-emoji picker supports multi-file selection with immediate sequential upload, following the same hidden-input handoff as normal chat file upload.
• New configurable message-tokens processor. English aliases are supplied by default, while administrators can add or replace aliases in any language.
• :enter: / :newline: / :nextline: / :linebreak: / :br: insert a new line.
• :blankline: / :emptyline: / :paragraphbreak: insert an empty line; :tab: / :indent: insert configured spaces.
• Printable custom substitutions such as :separator: can be defined by administrators. Unknown tokens are preserved for custom emoji compatibility.
• Existing configs keep their values and custom comments, while known top-level blocks are reordered to the bundled 4.7.0 layout on startup/reload; a full config-reference-4.7.0.yml and readable migration diff remain available for review.
