#8: New -exclude <expression> syntax to more easily and reliably filter out paths. For example:

bfs -name config -exclude -name .git

will find all files named config, without searching any directories (or files) named .git. In this case, the same effect could have been achieved (more awkwardly) with -prune:

bfs ! \( -name .git -prune \) -name config

But -exclude will work in more cases:

# -exclude works with -depth, while -prune doesn't:
bfs -depth -name config -exclude -name .git

# -exclude applies even to paths below the minimum depth:
bfs -mindepth 3 -name config -exclude -name .git

#30: -nohidden is now equivalent to -exclude -hidden. This changes the behavior of command lines like

bfs -type f -nohidden

to do what was intended.

Optimized the iterative deepening (-S ids) implementation

Added a new search strategy: exponential deepening search (-S eds). This strategy provides many of the benefits of iterative deepening, but much faster due to fewer re-traversals.

Fixed an optimizer bug that could skip -empty/-xtype if they didn't always lead to an action

Implemented -xattrname to find files with a particular extended attribute (from macOS find)

Made -printf %l still respect the width specifier (e.g. %10l) for non-links, to match GNU find

Made bfs fail if -color is given explicitly and LS_COLORS can't be parsed, rather than falling back to non-colored output
