Problem description

vim.tbl_xx functions used in mason will be deprecated in neovim 0.12, and just started throwing errors when starting Neovim 0.11 (NVIM v0.11.0-dev in my case, compiled from the latest source). Deprecation details can be found here and here.

Though I found several references to vim.tbl_xx functions in the source code, the error that I currently have with mason is:

vim.tbl_flatten is deprecated, use vim.iter(…):flatten():totable() instead. :help deprecated
Feature will be removed in Nvim 0.12

Thanks for a great project! Cheers
