Changes from 0.6.0 to 0.6.1:

Changes from 0.4.0 to 0.6.0:

Changes from 0.3.0 to 0.4.0:

Changes in build dependencies:

Newly implemented commands and statistical features:

Long variable names (and other identifiers) are now supported. Up to the first 64 bytes of each identifier is significant. PSPP now reads and writes system files compatible with SPSS version 12.

New --algorithm and --syntax command line options allow SPSS-compatible or enhanced modes to be selected.

Support for transformation expressions has been rewritten and significantly improved. Refer to the manual for details.

Calculation of moments (mean, standard deviation, kurtosis, skewness) has been rewritten and should now be more accurate. In --algorithm=enhanced mode moments may be more accurate than SPSS in some cases.

Numerous bugs have been fixed, too many to mention here. Many new tests have been added, leading to the discovery and fixing of many of these bugs.

The ASCII output driver can now squeeze multiple blank lines into single blank lines.

Much of the code has been rewritten and refactored. It is now much cleaner.

The FILE TYPE and REPEATING DATA commands have been disabled for this release because their implementations were deemed too buggy to be useful. They will be fixed and replaced in a future release.

New pspp-mode for Emacs (in pspp-mode.el).

Added rudimentary command-line completion for interactive input.

lib/julcal and lib/dcdflib are no longer used, so they have been removed.

For developers, the build system now requires Autoconf 2.58 and Automake 1.7. The included gettext has been updated to version 0.12.1.

Some reports state that Texinfo 4.8, the latest version, may be necessary to successfully format the documentation on some systems.
