- Drop support for Neovim 0.5. The plugin requires at least Neovim 0.6 now.
- Use new diagnostic API.
- Handle breaking changes in LSP utils functions. Fixes #32.
- Drop support for code actions: the handler for code actions cannot be overridden anymore in Neovim 0.5.1, see neovim#15848. But fuzzy search was never really suited for code actions anyway. Closes #25.
- Clean and comment code.
