[BUG] Plugins' incompatibility with SM 1.11

[StarterX4]

Describe the bug
As some plugins don't work with 1.11 without recompilation now, I think the support for 1.11 and up (in readme) should be corrected to just 1.12, or it should be noted that some plugins (or better all of them) should be recompiled under 1.11.

There were like two more plugins since this repo switched to 1.12, but just recompiled and forgot about them.
Though since the list is growing, I think we should point it out. Compatibility with 1.11 gets lost.
