Changes

v1.1.4 - Minecraft 26.3 Support

What's New in v1.1.4

Improvements

  • Minecraft 26.3 is now a supported and verified target. No plugin changes were required: packetevents' waypoint packet handling is unchanged from 2.10.1 through 2.14.0 (the release that added 26.3), so the existing locator-bar hiding and recoloring works on 26.3 as-is.
  • Firefly is now published to Modrinth with 26.3 in its game-version list.

Security

  • The bundled H2 database driver is updated to 2.5.252 (from 2.4.240). This fixes a URL-injection issue, adds a deserialization filter, and fixes SecureFileStore skipping decryption. Existing firefly.mv.db files open unchanged, and were verified to work both when upgrading and when downgrading back to 1.1.3.

Technical Changes

  • Firefly now compiles against the minimum supported packetevents, 2.10.1, so any use of newer packetevents API fails the build instead of breaking servers on older packetevents. The compiled plugin is byte-for-byte identical.
  • The full test suite (58 tests, plus the JaCoCo coverage gate) now also runs against the 26.3 Paper API. The 1.21.6 floor build is unchanged.

Breaking Changes

  • None in this release.

Requirements

Firefly needs the packetevents plugin installed. The minimum version depends on your server:

Server packetevents
1.21.6 - 1.21.11 2.10.1+ (first release with the full locator-bar waypoint API)
26.1 - 26.2 2.13.0+ (first release that knows the 26.2 protocol)
26.3 2.14.0+ (first release that knows the 26.3 protocol)

Running a packetevents version older than the minimum for your server will fail at runtime.

Installation

Download Firefly-1.1.4.jar and place it in your server's plugins folder.

Upgrading from a Previous Version

  1. Stop your server
  2. Replace the old JAR with the new one
  3. If you are moving to Minecraft 26.3, update packetevents to 2.14.0 or newer
  4. Start your server
  5. Player data and configuration are preserved across upgrades

Compatibility

  • Minecraft: 1.21.6+ (locator bar) through 26.3
  • Server Software: Spigot, Paper, Purpur, or Folia (Folia fully supported)
  • Dependencies: packetevents (see Requirements above)
  • Java Version: 21+ (tested on Java 21 and 25; Minecraft 26.x itself requires Java 25)

Known Issues

  • None at this time.
