Subject: [Tioga-news] Tioga 1.12 is released !
Message-ID: <4C9BC107.3020400@9online.fr>

  Hello dear Tioga users,

  I'm glad to announce a new release of Tioga, after more than a year
of silence. Quoting Tioga_README:

   "Tioga 1.12 has seen quite a lot of action. The first and major
change is the switch from a custom rewrite of mkmf.rb for
building/installing to the standard setup.rb tool, which finally has
the gem version build exactly the same way as the pristine one.

    Another side effect of this is that, for a big part thanks to
Carlo E. Prelz <fluido at fluido.as>, we now have tioga that works just
fine with Ruby 1.9.1 (though there is a weird bug while testing the
Flate library, we welcome any input on that).

    Apart from that, Tioga has seen many improvements on the numerical
side. First, we welcome the participation of Benjamin ter Kuile, who
has started improving some aspects of Dtable.

    Second, now Dvector is gifted with FFT capacities if the
development files of fftw3 are available at compile time (have a look
at the documentation).

    Third, Function has been endowed with a whole bunch of new
functions for data processing, such as linear regression, spline
approximation (that almost looks like a good filter !), 4th order
accurate first and second derivatives.

    Finally, a couple of annoying bugs were fixed."

  The upload is on its way, gems should be made available in just
about 10 to 20 minutes.

  Enjoy !

      Vincent, on behalf of the tioga development Team
