Looks like I saw the announcement before TidBITS was able to write an article.
CCC 6 is here! Faster backups, better accountability, Dark Mode, and so much more
As I wrote in my blog, this looks like a great release. I will probably wait until there have been 2-3 bug-fix releases because I never trust any version x.0 release of any product, but I will definitely be upgrading to it.
Of particular interest (at least to me) is faster file-copy and the use of Apple’s FSEvents API so it doesn’t need to scan every file on the computer in order to determine what needs to be backed up.
