BREAKING CHANGES

  • Support for Python 2 is dropped. For Python 3, the minimum supported version is 3.6. Legacy :pythonx commands are still available, and always uses the python 3 provider.

  • api: Existing usages of nvim_buf_set_text that use negative line numbers will be off-by-one.

  • highlight: signature of vim.highlight.range was changed.

  • input: distinguish between some input keys which previously were synonyms. This will break some exiting mappings.

    • <cr>, <tab> and <esc> are no longer considered equivalent to <c-m>, <c-i> and <c-[> respectively. In case the terminal or GUI supports distinguishing these keys, these can now be mapped separately. But even if the terminal only can send one code you might still need to change what variant is used in the config.
