See the end for copying conditions. Please send PSPP bug reports to bug-gnu-pspp@gnu.org. + +Changes since 0.4.2: + + The PROCESS IF command, which was deprecated, has been removed. You + may replace any usage of it by SELECT IF following TEMPORARY, which + has the same effect. -Version 0.3.1 changes since 0.3.0: +Changes since 0.4.0 to 0.4.1: + + Added support for very long string variables > 255 bytes. + + Output changes: + + * Output configuration options have changed. Please refer to the + manual for a full description of the available options. + + In consequence, you will need to reinstall your "devices" file. + "make install" will do this for you. + + * The PostScript driver now obtains font metrics from AFM files, + instead of Groff-format metrics files. It can now embed + PostScript fonts in its output. + + In consequence, you will need to install an AFM file for each + font used in PostScript output. "make install" will install AFM + files for the standard PostScript files, including the ones that + the PostScript driver uses by default. + + Newly implemented commands and statistical features: + + * CLOSE FILE HANDLE (a PSPP extension; see below). + + * REGRESSION. + + * XEXPORT (a PSPP extension). + + New PSPP extension: + + A new PSPP extension called "scratch files" has been implemented. + A scratch file, like a system file, consists of a dictionary and + any number of cases. Small scratch files are stored in memory; + one that grows too large is written to disk. By default, any file + handle whose name begins with # is assumed to refer to a scratch + file. + + Scratch files can be used just about anywhere a system or portable + file can be used. Also, portable files are now allowed in most + places that system files were allowed in previous PSPP version. + + A new CLOSE FILE HANDLE command allows the storage associated with + scratch files to be freed. It also allows file handles to be + reassigned to new files. + + For more information on scratch files, refer to the "File Handles" + section in the PSPP manual. For specifics of what commands now + allow what kinds of files to be specified, refer to the + documentation on those particular commands. + + PSPP is now able to start up and run even if it cannot find its + configuration files. + +Changes from 0.3.0 to 0.4.0: + + Changes in build dependencies: + + * The GNU Scientific Library (libgsl), version 1.6 or later, is + now required. + + * libplot from GNU plotutils is optional. Without it, the new + graphing features will not work. If you do not have it + installed, you must run `configure' with --without-libplot. + + * libgmp2 is no longer a dependency. - Update build system to Autoconf 2.58, Automake 1.7, gettext 0.12.1. + Newly implemented commands and statistical features: - T-TEST is now implemented. + * EXAMINE, including its graphing features. + + * FREQUENCIES now supports percentiles. + + * ONEWAY. + + * PERMISSIONS. + + * SHOW. + + * SORT CASES now sorts stably, that is, two cases with equal sort + criteria will be in the same relative order before and after the + sort. + + * T-TEST (re-written). + + * DATE and USE. These commands are parsed but otherwise ignored, + to enhance compatibility with certain command files that invoke + them unnecessarily. + + * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These + currently have no effect on PSPP output, but their values are + written to and read from system files and thus may affect + third-party software. + + * SET EPOCH implemented. + + * DATA LIST FREE and DATA LIST LIST now support arbitrary field + delimiters. + + * FILE HANDLE now supports custom tab widths. + + 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. + Version 0.3.0 changes since 0.2.3: Bugs fixed:
