I have an alias for Neovim that has alias e="nvim --listen /tmp/nvim.pipe". This alias stopped working correctly after upgrading to 0.11. I can only open a single instance of neovim. But I can’t open more than that; if I want to open a new instance, I must close the previous one.
Looks like the old behaviour was a bug Can't launch multiple instances of nvim after updating to v0.11 · Issue #33150 · neovim/neovim · GitHub
