Tol v1.1.4 released

After one and a half year of aparent inactivity, most of them dedicated to work in projects around Bayes Decision SL, the company behind Tol, the Tol Development Team is pleased to announce the availability of Tol 1.1.4 under the terms and conditions of GNU General Public License (GNU GPL License).

As its 2nd digit stands for, this is still an unstable release, with lots of bugs fixed and several improvements, such as:

• Better TimeSet and Series Algebra implementation, and a better performance in Tol Types operations.
• The implementation of a test framework has being done, which is far from being complete but at least cover a regression test for bugs reported. A simulation test is also implemented for estimation of ARIMA models and timeset algebra. This framework will be in continuous development in order to warranty the increasing quality of TOL from version to version.
• The distribution of Tolbase for windows is based on a more recent Tcl/Tk 8.4.14 which is more stable.

Apart from this announce, and due to requirements of Tol are constantly evolving, from now on we are encourage to produce a new release of Tol each 3 or 4 months, what we call a development cycle. During each development cycle we produce a bunch of bugs fixed that will be tested, and new features that will be presented and properly documented before the release date.

We are already able to present two of those new features for the next release of Tol v1.1.5:

• OIS, stands for Object Index Serialization, a powerful module closed to Kernel of Tol, which comes to save our time and our day sessions, and
• An improvement in Database access based on two facts: a far from new but enough to say a reimplementation of Tol Internal Database API, and a new Driver to get direct access to PostgreSQL, one of the most used Open Source Database engine.

This new unstable release has fixed many errors reported for the language (errors reported under Tol product) and for the interface (errors reported under Tolbase product). You can get Tol from the CVS Repository as well (visit Developers Section).
