As usual, see https://gretl.sourceforge.net/ Changelog entry: 2023-07-21 version 2023b - New command "kdplot": simple access to a kernel density plot for a single series - New function typename(): return a string giving the type of the argument (can replace typeof() and typestr()) - "arima" command: implement built-in procedure for assessing lag orders, via new --lagselect option, and add GUI access - "corr" command: add 1 percent critical value of correlation coefficient to the output - "join" command: import descriptions of newly-added series, if present - "gnuplot" command: add new options --inbuf and --outbuf to accept, respectively, input from a named string and output to a named string - "smpl" command with the panel-data --time option: support the --replace modifier - "outfile" command: insist on correct syntax for usage with the --tempfile option - aggregate() function: support matrix input - misszero() and zeromiss() functions: support matrix input - SVAR addon: implement mixed (set-based and zero) restrictions - geoplot addon: make the plot key position configurable - regls addon: add an mregls() function for working with data in matrix form - Add optional boolean "skip_na" argument for several matrix functions that compute statistics - Functions bkfilt, bwfilt, fracdiff, filter: disallow panel data since these functions assume regular time-series data - Boxplots: respect the chosen gnuplot theme, if applicable - Add "empty" as a dummy constant for initializing an empty string, matrix, bundle or array - "numeric" meta-type: allow usage in function packages, and hook it up for syntax highlighting - Function packages: support use of Markdown for help text - Function packages: add a new special function role named "ui-maker" to support customization of the user interface - "R_functions" facility: handle row and column names when passing matrices to and from R - Fix bug: failure in the Kalman function ksmooth() when in "univariate" mode and the observable has more elements than the state - Fix bug: possible failure in "smpl" with the --time option for panel data - Fix bug: memory corruption on trying to append an array to itself - Fix bug: single-equation LIML could fail when there's no constant in the specification - Fix bug: spurious "no data avilable for forecasting" error in GUI forecasting from ARIMA model without constant term - Fix bug: function package code with very long lines could lead to a crash (e.g. on "View code" in the GUI) - Fix bug: the sumc() function produced incorrect result for complex matrices (too large by 1) - Fix bug: potential crash on calling a hansl function with no arguments when it has only optional parameters - Fix bug: MPI crash on broadcasting an empty matrix, with some MPI variants - Fix bug: potential crash in estimating a restricted VECM when there are no regressors outside of the cointegration space - Fix bug: potential crash in "arima" with the --x-12-arima option with data starting in the year 1 - Fix GUI bug: dynamic panel data model menu item not always available when it should be - Fix GUI bug: breakage on trying to select the decimal comma when exporting data as CSV - GUI "Check for addons" facility: redesign to present the information more clearly - GUI sample selection for panel data: clarify and fix - GUI "stop" button to abort script execution: make this more responsive - GUI "dataset structure wizard": improve the efficiency of checking candidate unit and time variables for panel data - Add new example data file: sunspots time series from 1740 - User's Guide: updates, including description of data file formats - Add more strings to gretl.pot and update translations - 64-but Windows build: update to OpenBLAS 0.3.23 and MS-MPI version 10.1.3 -- Allin Cottrell Department of Economics Wake Forest University
