A very detailed changelog and discussion can be found here:

This change was built locally and tested by me. There will be changes
noticable in the `canto-curses` interface since color support has been
reworked. For more details follow the hint in `canto-curses` or read the
changelog/manual liked to above. There also have been many
under-the-hood improvements which can also be found in the link above.
