Hello everyone, it's once again time for a new release of LuaSnip :)
While this is prompted by a fix to a breaking change in Neovim 0.12, it contains a relatively complete overhaul of snippet updates, which marinated for some time in #1137, and then on master.

Self-Dependent DynamicNode

This change allows dynamicNodes to trigger updates that completely replace them. While technically possible before, it is now fully supported and allows fun stuff like replacing spaces with underscores and uppercasing everything

or "moving" entire expanded snippets around within choiceNodes via restoreNode (which does not require any changes, it's just possible now):

s("test", {
    c(1, {
		fmta([[
			{
				"item1": "<c1>",
				"item2": "<c2>"
			}
		]], {
			c1 = r(1, "c1", i(1)),
			c2 = r(2, "c2", i(1)),
		}),
		fmta([[
			[
				"<c1>",
				"<c2>"
			]
		]], {
			c1 = r(1, "c1"),
			c2 = r(2, "c2"),
		})
    })
}
