Detailed changes can always be found in the Detailed Change Log, but here are some of the major features of this version.

- Performance improvements, as well as a "large file" mode for handling extra large files.

- Edit using Elastic tabstops, set from Global Options - Editing, Buffer Options, or via buffer-local properties.

- Lots of old deprecated APIs were removed. Some plugins may be broken as a result.

- It is possible to specify a `FILE_NAME_GLOB` for an edit mode based on the full path (see entry for `apacheconf` mode in `modes/catalog` for an example) (Feature #2557712).

- File System Browser can now open files in desktop, using desktop filename associations to launch another program.

- Plugin Manager Enhancements, filter field, bugs fixed.
