1.8.3-alpha.2

Changelog

[1.8.3-alpha.2] — 2026-09-26

New version format: version.subversion.patch-<channel>.<number> (e.g. 1.8.3-alpha.2).
Channels from bleeding edge to stable: Nightly → Snapshot → Alpha → Beta → Release.
The core and all 11 addons ship with a single family version; third-party addons may use their own.

⚠️ Changed — Versioning system

• Switched to the version.subversion.patch-<channel>.<number> format; this iteration's line:
  1.8.3 → 1.8.3-beta.1 → 1.8.3-alpha.2
• Updated everywhere: Gradle version, plugin.yml (via ${project.version}), plugin_version
  in config.yml and the bundled UI-Core.toml template, the README badge, and the CONTRIBUTING example
• All 12 JARs rebuilt: UI-*-1.8.3-alpha.2-all.jar; distribution archive
  UltimateImprovments-1.8.3-alpha.2-jars.tar built and verified (gzip integrity + extraction check)
• Existing servers keep their on-disk plugin_version value (as before)

✨ Added — Hazmat suit (replacement for the Lead Shield)

• New radiation protection armor: 4 leather-based pieces (helmet / chestplate / leggings / boots),
  yellow-green color, PDC tags ui:isHazmatHelmet/Chestplate/Leggings/Boots
• Each worn piece gives −20% incoming radiation (weakened, not removed); full set gives −80%
• Armor is re-scanned every 2 seconds (scan_interval_ticks = 40) with a cache — minimal overhead
• Works against every source: ancient debris, Basalt Deltas, the End, space, reactors
• Recipes use the exact vanilla gold-armor shapes with ONE gold slot replaced by a Lead Ingot:
  • Helmet GPG / G G
  • Chestplate G G / GPG / GGG
  • Leggings GPG / G G / G G
  • Boots G G / P G
• Craftable only in the Crafter (the workbench shows the recipe but yields nothing)
• Lead Ingot anti-uncraft protection whitelists the hazmat recipes — ingots are legally consumed
  but cannot be melted back
• New config section hazmat (UI-Shared): enabled, scan_interval_ticks, protection_per_piece = 0.2,
  full_suit_bonus = 0.0; supports /ui reload
• Hazmat pieces available in the omniscanner admin menu (replacing the removed shield)

✨ Added — Datapack: new recipes and advancements

• New recipes: book, ender chest, Eye of Ender, mace, trident, nether star, shulker box,
  blaze powder, iron chain, amethyst (including uncraft and budding amethyst), melon uncraft,
  netherite smithing template duplication, reinforced deepslate
• Advancements added/updated to cover the new recipes

🛠 Fixed

• Custom enchantments never appeared in the enchanting table. Root cause: all 17 datapack
  enchantments used min_cost = max_cost = 30, degenerating the level-1 availability window to a
  single point that the table's random roll practically never hits. Fixed in the datapack itself
  (no listeners): a 25–75 window, same shape as vanilla Mending — level 1 is now reliably offered
  on the third (level-30) button, lower buttons stay vanilla. Also verified the
  minecraft/tags/enchantment tags — all 17 charms are present in all five tag files
• Repository cleanup: removed 263 stale bin/main/ build-output copies from git;
  added ui-mbs/logs/ to .gitignore

🔧 Changed

• Lead Ingot lore: "Used to craft the Dosimeter and the Hazmat suit" (shield mention removed)
• createLeadIngotStack() factory moved into LeadIngotCraftListener (shared by the dosimeter and hazmat)
• Ender chest crafting and parts of other recipes moved from plugin listeners into the datapack
  (EnderChestCraftListener and related ui-energy assembler/workbench classes removed)
• ui-core: updates to CommandErrors, SubCommandRegistry, ConfigRepairManager;
  new classes CommandOutcomeTracker, AddonsSubcommand, TomlCrashSalvage
• ui-datapack: reworked DatapackInstaller, updated loot tables and recipes (bookshelf, netherite, etc.)
• ui-shared/ui-other: crafting listener updates, space oxygen (SpaceOxygenListener), recipe registry
• ui-anticheat / ui-chat / ui-clans / ui-combat: routine module updates

❌ Removed

• Lead Shield: item, recipe, ui:isLeadShield PDC key, admin-menu entry. Existing shields in
  players' inventories remain but lose their radiation protection
• Config keys radiation.lead_shield_reduction and the never-applied radiation.antirad_reduction
  (leftover keys in on-disk toml files are harmless — repair ignores them)
• Obsolete ui-energy classes: AssemblerChecker, ItemCreatorRecipe, EnergyCraftingListener

🧰 Internal / Tooling

• Scripts/build/package_jars.sh — distribution archive builder (build → gzip → tar) with automatic
  version detection from the JAR name
• Added CHANGELOG.md
• hazmat config section routed to UI-Shared (AddonCatalog + TOML template generator)

Compatibility

No data-breaking changes: configs, the database (player_radiation) and player items are unaffected.
Functional changes: the Lead Shield no longer provides protection (replaced by the hazmat suit),
and custom enchantments now actually appear in the enchanting table.
