Hmm, this is a breaking change.

[JosefLitos]

Hmm, I thought I checked everything. From what I've found, all uses were withing the plugin internals. That shouldn't affect the user because they don't have direct access (or at least, I believe, have no reason to use it directly). Is there something I can help with?

[zeertzjq]

Well, I used v:lua.MPairs directly in my mappings. Replacing them with v:lua.require'nvim-autopairs' will work, although I just discovered a bug in Nvim that causes it to error sometimes.

You should be able to call it the same way I made the changes in the plugin - as a <Cmd> or a function callback. Though it is something that users using the global directly do have to change due to this PR.

These changes seems to make neovim freeze when the plugin's behavior is triggered, see comments on 2e8a10c
