One JAR now supports Paper 1.21.10, 1.21.11, 26.1.1, 26.1.2, 26.2 and 26.3. Use Java 21 for the 1.21 versions and Java 25 for 26.x.

• Fix inventory editing so closing a viewer cannot overwrite newer items; validate equipment, slot transfers and simultaneous viewers.
• Preserve stacked XP totals and vanilla pickup/Mending behavior when merging orbs; respect cancelled events and differing sources.
• Bound and deduplicate leaf-decay work, avoid loading unloaded chunks, and preserve persistent leaves.
• Back up and migrate old configuration while retaining user values and custom keys; preserve malformed files.
• Clean up vanish resources and cache shortcut/command settings with a configurable shortcut cooldown.
• Fix explosion protection for Paper damage events reported as CUSTOM, using standard public damage types.
• Stop repeated Mojang profile requests for inventory heads without available skin textures.
• Remove six unused test imports; add bilingual documentation, sponsor links and structured bug/feature feedback.

Validation: 32 tests in each of six API environments; real-server baseline evidence contains 222 functional checks and short 20-client pressure scenarios. The release report identifies the baseline artifact, class-file equivalence and release-specific checks. Only the listed Minecraft releases are supported; Spigot, Folia and pre-releases are outside this release's scope.
