Just found out that my favourite diff tool Beyond Compare announced availability of its 4th version, currently in Beta. In fact, it is now an old news, as the announcement was made at the end of December 2013. The major change (in my opinion) is support of Mac OS X.

What seemed interesting to me, is that the Mac OS port was implemented with help of Lazarus.
Obviously, Deplhi (and Pascal) is not this dead!
