Changelog – v1.6.1 (21.10.2026)

Added

• Combined Upgrader stakes: players can stake Vault money and multiple item stacks in the same attempt
• Expanded the player Upgrader input area to a 3×3 grid with nine independently valued item stacks
• Added a custom Add Money prompt and a combined stake breakdown in the UPGRADE tooltip
• Added configurable input stacking with upgrader-settings.input-stack.enabled (enabled by default) and max-items
• Added durability-aware automatic item valuation, so damaged tools, weapons and armor are worth less than fully repaired items; this can be disabled in config.yml
• Added custom Upgrader item registration with /lc upgrader additem <id> <value>, /lc upgrader listitems and /lc upgrader removeitem <id>
• Added reward-type: COMMAND for explicit Upgrader profiles, with console execution and {player}, {uuid} and {amount} placeholders
• Added a durable Upgrader transaction journal with recovery and review states for attempts interrupted by a restart
• Added /lc upgrader-review for manual review of Upgrader transactions with uncertain cost outcomes
• Added /lc reward-review to inspect and resolve command rewards whose delivery state is uncertain
• Added /lc perf to report Upgrader animation timing and active case-session, task and visual-entity counters
• Added core-aware update streams for Paper/Purpur and Spigot, plus update notices in the server console
• Added JUnit regression tests for transaction recovery, custom item serialization, durability valuation, input-stack values, archive safety, storage recovery and snapshot ordering

Changed

• Reworked the player Upgrader GUI: stake details are consolidated into the UPGRADE tooltip, the main action uses a fixed Nether Star icon, and a glass divider separates the stake and target areas
• Reworked the Upgrader cost editor to support combined Vault and item costs; item subtotals and money are included in the displayed total
• Expanded upgraders_cost.yml with category-grouped default values, value-balancing guidance and custom-item instructions
• Expanded config.yml comments and examples to explain storage, rarity weights, luck, Upgrader profiles, stack values, durability valuation and command rewards
• Kept upgraders: {} empty by default and clarified the distinction between automatic value-based targets and explicit Upgrader profiles
• Serialized YAML snapshots on the main thread and moved disk writes to an ordered background writer that skips stale pending snapshots
• Added transactional switching between YAML and SQLite key/luck snapshots, including read-back verification, rollback copies and startup recovery for interrupted switches
• Reduced repeated Upgrader animation geometry calculations and added performance counters for profiling
• Renamed the admin entry to Upgrader Profiles to clarify that it edits profiles rather than placing world-based Upgrader points
• Preserved compatibility with legacy MONEY and ITEMS profile cost settings and legacy animation aliases

Fixed

• Fixed backup entries overlapping action buttons in the Backup/Restore GUI; the list now uses a dedicated area with up to 21 entries per page
• Hardened archive restore against path traversal, duplicate or case-colliding paths, unsupported files, oversized archives and suspicious compression ratios
• Added staged archive validation for YAML, SQLite integrity and required data files before live data is replaced
• Added rollback and interrupted-restore recovery for archive restores and safer recovery for corrupted configuration, history and storage files
• Improved Upgrader crash recovery by journaling attempts before consuming the input and tracking uncertain cost application without issuing unsafe automatic refunds
• Made pending reward delivery more resistant to duplicate queueing and interrupted item delivery by using stable IDs and delivery receipts
• Routed command rewards with uncertain dispatch outcomes to manual review instead of blindly executing them again
• Fixed a partial-stack inventory transfer edge case that could duplicate items when the player's inventory had insufficient space
• Removed the obsolete Upgrader-use forwarding menu and an ineffective bundled example profile superseded by automatic target generation
• Added connection cleanup and a bounded busy timeout for SQLite operations
