See the end for copying conditions. Please send PSPP bug reports to bug-gnu-pspp@gnu.org. + +Changes since 0.8.4: -Changes from 0.6.2 to 0.7.10: + * SPSS/PC+ system files are now supported on GET and other commands + that read SPSS system files. The pspp-convert program can now read + SPSS/PC+ system files. Writing the obsolete SPSS/PC+ system file + format is not supported. + + * SYSFILE INFO can now read SPSS/PC+ system files and SPSS portable + files. + + * FREQUENCIES: A bug was fixed where an assertion failure occured + when an empty dataset was presented. + + * The GRAPH command is now available. Initially it supports + scatterplots and histograms. + +Changes from 0.8.3 to 0.8.4: + + * Formatting of SYSFILE INFO output was made easier to read. + + * Bug fixes, including the following notable ones: + + - FREQUENCIES works properly for string variables. (This bug was + introduced in 0.8.2.) + + - CROSSTABS now correctly computes all of the measures that it + offers. Some measures have been removed because they were not + computed correctly. + + - The NPAR TESTS calculation of significance for the RUNS + subcommand has been corrected. + + - Planned comparisons in ONEWAY ANOVA now correctly handle negative + T-values. + + - Conformance fixes to Open Document output format. + +Changes from 0.8.2 to 0.8.3: + + * Independent T-Tests displayed the standard error of the difference + and the confidence interval for the unequal variances case, where + the equal variances case should have been. This has been fixed. + + * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence + intervals for the coefficients to be printed. + + * When DESCRIPTIVES calculates Z scores, it now omits cases filtered + by the current FILTER settings. + + * PSPPIRE graphical user interface improvements: + + - Dialog boxes with source variable lists can now choose the sort + order; right click and select from the popup menu. + + - File|Open now allows an encoding to be selected for opening + system files. + + - File|Display Data File Information|External File... now allows an + encoding to be selected. + + - A problem with the Means dialog has been resolved (bug #41433). + + - Several problems related to the input of spreadsheets have been + fixed (bug #41657, #41620 + + * System file related improvements: + + - With ENCODING="DETECT", SYSFILE INFO can now help the user to + pick an encoding for reading a system file that does not identify + its own encoding + + - SYSFILE INFO now accepts an ENCODING subcommand to specify the + character encoding of string data in the system file. + + - Variable labels over 255 bytes long are now accepted without + truncation (bug #41863). + + - System files that contain duplicate variable names may now be + read successfully (bug #41475). + +Changes from 0.8.1 to 0.8.2: + + * Charts are now rendered with colours from the Tango palette instead + of fully saturated primaries. + + * Support for new system file variants: + + - PSPP can now read and write ZCOMPRESSED system files, which + compress data much more effectively than older "compressed" + files. (The older format is still supported.) + + - PSPP can now decrypt encrypted system files, using the new + pspp-convert utility. The encrypted system file format is + unacceptably insecure, so to discourage its use PSPP and PSPPIRE + do not directly read or write this format. + + * Missing values for long string variables are now read from and + written to system files in an SPSS-compatible fashion. + + (Earlier versions of PSPP that supported missing values for long + string variables wrote them to system files in an SPSS-incompatible + way. To fix the problem, read the system file with this version of + PSPP and then save a new copy of it.) + + * pspp-convert, a new standalone utility for converting SPSS system + and portable files to other formats, is now included. The initial + version supports comma-separated value files as output format. + pspp-convert can also decrypt encrypted system files. + + * Build changes: + + - zlib is now a required dependency. (Previously it was optional.) + +Changes from 0.8.0 to 0.8.1: + + * New commands: + + - VARIABLE ROLE. + + * Changes to existing commands: + + - CROSSTABS: The requirement that one expected count must be less than five + before Fishers Exact Test will be reported has been removed. + + * PSPPIRE graphical user interface improvements: + + - A new set of icons has been contributed. + + - Syntax windows now parse syntax in "auto" mode, which in practice + should mean that both "batch" and "interactive" syntax now works, + instead of just "interactive" syntax. + + - The variable pane of data windows now include a Role column. + + * Notable bug fixes: + + - System files written by IBM SPSS 21 are now read without warnings. + + - System files written by "VOXCO INTERVIEWER 4.3" are now read + without warnings. + + - PSPPIRE should now more gracefully handle syntax files that contain + errors. + +Changes from 0.6.2 to 0.8.0: * New commands:
