Changelog

All notable changes to ItemHighlighter are documented here. The format follows Keep a Changelog. ItemHighlighter is versioned semantically (MAJOR.MINOR.PATCH). It runs on Minecraft 26.3 (Fabric + Forge + NeoForge, Java 25) and requires Mycel (my.celium.org).

[1.0.1] - 2026-10-10

Changed

• Updated Mycel lib to 1.2.1.

[1.0.0] - 2026-10-10

Added

• Initial release.
• /hl client command (no permissions needed): /hl #RRGGBB highlights the held item type (legacy &/§ codes work too), /hl uses the configured defaultColor, /hl clear removes the held item's highlight, /hl list shows every highlighted item with a color swatch.
• Per-item-type highlights with custom colors, persisted across restarts in config/itemhighlighter_data.json (up to 256 items, oldest dropped first).
• matchComponents config: when true, only stacks identical to the highlighted one match (same enchantments, custom name, damage and other components); when false, every item of the same type highlights.
• Glowing world outline for dropped items and item frames holding highlighted items, using vanilla's own glow rendering (nearest of the 16 palette colors; the exact color still shows in the hotbar, tooltip and /hl list).
• Texture-hugging tint over highlighted item sprites in the hotbar, offhand, inventories and containers: opaque texels tinted, crisp outline plus soft halo on adjacent transparent texels, empty sprite corners untouched.
• Colored ★ Highlighted tooltip line on highlighted items everywhere (inventory, chests, recipe book, creative menu); rarity colors and other tooltip lines untouched.
• Config (config/itemhighlighter.json): enabled, defaultColor (0xFFFF55), showTooltipLine, hotbarHighlight, matchComponents. Reload live with /mycel reload itemhighlighter; config screen available from the mod list on Forge and NeoForge.
• Client-side only, no keybinds. Built on Mycel 1.2.1 (com.github.MyCelium-GG:MyCel-Lib:1.2.1 via JitPack).
