This update brings improved compatibility with Paper 1.21.10 and Paper 1.21.11.

InvSee++ v0.30.x will be the final major.minon release series of InvSee++ which will make use of Paper's spigot plugin bytecode transformer for compatibility with Paper, with 0.30.14 likely being the final version of that series.

Going forward, InvSee++ versions 0.31.x and up will have built-in support for Paper natively, without making use of their remapper. One downside of this change will be that starting from InvSee++ 0.31.0, InvSee++ will no longer be compatible with versions of Paper older than 1.21.11.
Users of Paper 1.21.10 and lower are advised to stick with InvSee++ 0.30.14.
