[Gretl-users] gretl 2026a released

As usual, see https://gretl.sourceforge.net/ The biggest change is our update from the Mersenne Twister (SFMT) to xoshiro256+ for pseudo-random number generation. 2026-01-30 version 2026a - mat2list(): fix potential crashing bug; enhance by using the t1 and t2 values on the matrix argument, if present - binary logit/probit: use QR decomposition in tricky cases where the Hessian may otherwise end up not p.d. - "difftest" command: support the --split-by option for the rank sum test - "print" command: add --head (-h) and --tail (-t) options as convenient abbreviations for the --range option - "gnuplot" command, --y2axis option: accept a named list as parameter, or comma-separated series - "open" command: support the --all-cols option for xlsx and gnumeric importation - "data" command: fix possible problem with long db.nomics series identifiers - "xcorrgm" command: save a $result matrix and add a --quiet option - "quantreg" command: support $coeff and $stderr accessors for the multiple-tau case - "gnuplot" and "plot" commands with --band option: support giving the center and width of the band as scalars if they are not varying - fix bug: possible crash from kdsmooth() when there's no disturbance in the observation equation and exact diffuse initialization is not employed - fix bug in regls() with cross validation using MPI: it could happen that too many MPI processes were employed, leading to broken results - fix bug in GUI deletion dialog: destroying the dialog could be taken as indicating "OK" - updates and fixes for documentation - macos arm64 build: ensure that __divdc3 is defined - 64-bit Windows build: ensure that libreadline is supplied - random number generator: replace Mersenne Twister with xoshiro256+ -- Allin Cottrell Professor Emeritus of Economics Wake Forest University, NC
