See https://gretl.sourceforge.net/ The change log follows: 2023-03-02 version 2023a - "logit" command (binary case): add a matrix holding odds ratios plus standard errors and confidence intervals to the $model bundle; also make this information available under the Analysis menu in the GUI model window - "set" command: add key "hac_missvals" to select the policy for HAC estimation when there are incomplete observations; and make the Equal Spacing method the default - "gnuplot" and "plot" commands: putting an .html suffix onto the output filename now invokes gnuplot's "canvas" driver - "midasreg" command: generate more specific error message for invalid specification - "fcast" command: enable the --plot option for forecasts based on a system, when a single series is selected; introduce --all-probs option for ordered logit/probit and multinomial logit models - "system" command: ensure that the $system bundle includes the sample limits as "sample_t1" and "sample_t2" - strptime() and strftime() functions: generalize to allow vectorized usage, and add variants (strpday, strfday) to work with epoch days rather than Unix time - pexpand() function: add optional boolean switch to expand in the cross-sectional dimension - readfile() function: ensure that we construct a legitimate local filename when downloading a web resource - normtest() function: add option to include all available tests in the returned matrix - int() function: return NA if the integer part of the argument lies beyond the range of a 32-bit signed integer - instring() and strstr() functions: drop the policy of auto- escaping the string to be found - qform() function: introduce alternate syntax for the case when the middle matrix is diagonal - CSV data importation: be less hasty in concluding that the column separator is comma - CSV importation via GUI: clarify the dialog that governs how the first column is treated; also don't show any string tables at the moment of importation (strings tables can now be accessed under the Data menu) - "join" via the GUI: make it evident that specifying keys may not be necessary with time-series data; fix a bug with use of the filter option - Script editor, split pane: ensure that when line-numbering is selected it carries over to the new pane; also improve tab-completion for names of functions - Drag and drop of data file onto gretl: offer a choice of replacing or trying to append to the current dataset - Fix error message for invalid (string) array index - Fix error message for missing function-package dependency - Fix bug: buffer overrun when creating names for transformed series if the original series has a very long name - Fix bug: crash on doing "pkg install" from the command line when the window listing function packages on the server is displayed at the time - Fix bug: possible false positive when checking for duplicate function packages - Fix bug: the weekday() function could produce an off-by-one error in some cases - Fix for detection of the R executable when called via a foreign block on macOS - configure/build apparatus: add support for using Intel's oneAPI and MKL, or libblis + libflame, for BLAS and LAPACK functionality - macOS build: include TargetConditionals.h in libgretl.h - MS Windows: work around the limitations of mktime() and localtime() using GLib functionality - geoplot addon: document the facilities available for plotting qualitative data; fix a bug whereby writing a map as an image file (e.g. PDF) could fail - Gretl User's Guide: rewrite the "Calendar dates" chapter including more information on the available formats and the means of converting between them - Reinstate old function file path for backward compatibility -- Allin Cottrell Department of Economics Wake Forest University
