Please see https://gretl.sourceforge.net/ Windows users: Note that there's now an ARM64 package available: https://gretl.sourceforge.net/win32/ The changes: 2025-06-05 version 2025b - gretlcli: add --no-plots option to suppress plots - "add" command: add an --auto option for forward stepwise regession via QR algorithm - new function thresh() for hard and soft thresholding - new function pxmean() for cross-sectional panel mean - "gnuplot" command: generalize the --dummy functionality for factorized plots; update and improve the help text - curl() function: add an option to skip downloading of the body of the requested URL - cnameset() and rnameset(): these functions now flag a warning if the number of names given does not match the relevant matrix dimension; this will become an error in a future release - Fix bug: correct the disturbance smoother for the de Jong variant of the Kalman filter; also fix a memory leak - Fix bug: poor handling of vector added to a bundle "as a series" when the dataset is sub-sampled - Fix minor bug: bad initialization in legacy Kalman code - internals: make gretl_get_data() support more data file formats; several small fixes to quell errors and warnings from gcc 15 and clang 20; add some code to facilitate new gretl4py functionality - GUI: fix the action of the "Stop" button when running a packaged function from the function-call dialog - GUI: relax the restrictions on the number of lags that can be selected in the model specification dialog - GUI: rejig the main-window "Add" menu and also the pop-up context menu for single series - regls addon: miscellaneous small fixes and tweaks - cleanup: delete the long-deprecated eigengen() function - Windows: add a gretl package for Windows on ARM64 - macOS: drop the "Calculator" button in the main window toolbar, since this stopped working as a result of recent security updates; also drop usage of otool by libgretl_init() - macOS: fix for launching gretl by double-clicking on a gretl script or data file - update translatable strings -- Allin Cottrell Professor Emeritus of Economics Wake Forest University, NC
