Changelog

v3.0.0-alpha.2 — 2026-05-12

Added

• <click> and <hover> markup tags for interactive text. <click> accepts action= (open_url, run_command, suggest_command, copy_to_clipboard) and value=. <hover> accepts action= (show_text, show_item, show_entity) and value=. Nested tags override parent click/hover values.
• <lang:KEY> markup tag resolves vanilla translation keys in each viewer's client locale. Shorthand <lang:item.minecraft.diamond> or attribute form <lang key=KEY> / <lang key=KEY args=A,B,C> for placeholder substitution. Missing keys render literally; translation file content is not re-parsed for ETA tags. Closes #2.
• ImmersiveMessage.decode re-parses markupSource on the client (1.20.1 and 1.21.1) to ensure server-issued messages resolve markup in the receiving client's locale, matching the existing behavior on 26.1.
• Patchouli compatibility: @Pseudo BookTextParserMixin plus a PatchouliBypass thread-local that suppresses ETA markup rewriting in LiteralContents, TranslatableContents, and StringSplitter while Patchouli is parsing book text.

Fixed

• SDF glyph pre-baking no longer repeats on every FontManager reload (initial load, F3+T, resource pack swap, datapack reload). Pre-baked MSDF data is now held in a process-lifetime cache keyed by (font fingerprint, SDF config), so reloads after the initial bake short-circuit the async pass.
• SDFGlyphProvider.closed is now volatile, so the background pre-bake loop reliably observes provider close.
• <click> and <hover> participate in the mixin render-gate, so click/hover-only spans no longer fall through to vanilla rendering on 1.20.1, 1.21.1, and 26.1.
• Lang-only markup (<lang> with no other tags) renders through the ETA mixin pipeline instead of bypassing it.
• Immersive-message HUD layer no longer leaks disableDepthTest and enableBlend into world rendering. Previously, on 1.20.1 and 1.21.1, the layer wrapper toggled global GL state every frame without restoring it, causing the skybox to disappear on Fast graphics and the hotbar background to drop out on Fabulous. The wrapper now matches the 26.1 pattern: just push/translate/render/pop. Render types and BackgroundRenderer already set up their own blend state.
