[Gretl-announce] 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+
