This is the official branding that Parabola adopted in 2013.

The discussion of the change mostly took place at
  https://labs.parabola.nu/issues/282

The files have been renamed from the original artwork to be (in my
opinion) friendlier, and the SVGs have been simplified (notably, they
use the `<text>` elemant, instead of embedding each letter as a
path), and other variants of the logotype have been added.

In the originals, the tittles on the "i"s in the logotype were rotated
45 degrees; this was not done with the text in this version.  This is
a bug <https://labs.parabola.nu/issues/781>.

See the 'official/2013-originals' branch for the original artwork
files, and the 'official/2013-paths' branch for simplified SVGs that
still use paths instead of text.
