LPC 4.3.0 — Multi-version support (Paper 1.21.x and 26.2)

This release ships two jars so LPC runs on both old and new servers. Pick the one for your platform on the Modrinth download page (Modrinth's game-version filter shows the right one automatically):

Build	Minecraft	Java	Adventure	api-version
LPC-4.3.0.jar (default)	26.2	25	5.2.0	26.2
LPC-4.3.0-legacy.jar	1.21.x (incl. 1.21.11)	21	4.23.0	1.21

Why two jars?

Adventure 4 (bundled by Paper 1.21) and Adventure 5 (bundled by Paper 26.2) are binary-incompatible — a single jar cannot reliably run on both. The same LPC source now compiles + passes all tests against both Adventure versions; the Gradle -Ptarget=modern|legacy switch selects the platform.

🔒 Still includes the 4.2.0 security fix

The defence-in-depth ComponentSanitizer (strips click/hover/insertion from player & item-name output) is in both builds.

Bug fixes & UX

• Fixes the recurring "Unsupported API version" / "plugin won't load on 1.21.11" reports — use the -legacy jar on Paper 1.21.x / Java 21.
• /lpc version now reports the build target (e.g. Build: Minecraft 1.21.x · Java 21 · Adventure 4.23.0 (legacy)) so support can tell which jar you installed.
• build.yml CI runs a modern + legacy matrix on every PR.

Installation

• Paper 26.2 / Java 25 → download LPC-4.3.0.jar
• Paper 1.21.x / Java 21 (incl. 1.21.11) → download LPC-4.3.0-legacy.jar

Requires LuckPerms. PlaceholderAPI optional.
