StructureCycle 1.0.0

The first stable release of StructureCycle is ready for production use on supported Bukkit-family servers.

Highlights

• Discovers vanilla and data-pack structures directly from the server registry.
• Captures exact piece-based baselines, including block states, containers, block entities, and entities.
• Restores structures manually or on configurable automatic schedules without regenerating chunks.
• Creates a retained backup of the live structure before every reset for rollback.
• Includes a paginated admin GUI with filters, structure details, boundary previews, controls, and confirmation screens.
• Supports manual, automatic, and disabled policies with per-structure mode and cooldown overrides.
• Blocks resets while players are inside the configured safety area and identifies the blocking players.
• Tracks player and environmental changes involving blocks, buckets, explosions, pistons, and entity block changes.
• Protects data with operation locking, atomic metadata saves, transactional baseline replacement, and interrupted-capture recovery.
• Requires no dependencies and includes no telemetry, advertisements, accounts, or external services.

Compatibility

• Minecraft 1.21.4 through 26.3
• CraftBukkit / Spigot
• Paper
• Purpur
• Compatible Bukkit/Paper forks are expected to work but should be tested before production use.
• Folia and proxy installation are not supported.

The same release JAR was boot-tested on Paper 1.21.4, 1.21.11, 26.1.2, 26.2, and 26.3, plus Purpur 1.21.11, 26.1.2, and 26.2.
