2026-10-29 version 2026d
- Fix bug: potential crash when forecasting based on a
  VAR estimated in the GUI
- Fix bug: the "must-assign" attribute of packaged functions
  was not being registered in the function-package GUI
- Fix bug: potential crash in the deseas() function on
  getting an error from X-13ARIMA-SEATS
- Fix bug: missing data in the updated AWM macro dataset
- L-BFGS-B: the code (originally translated from Fortran via
  f2c) has been rewritten in idiomatic C
- L-BFGS-B: more robust handling of a criterion that is
  undefined at some points: back off on encountering a
  non-finite criterion or gradient, rather than terminating
- L-BFGS-B: never evaluate the criterion outside of the
  specified bounds (one-sided numerical derivatives at a
  bound; guard against rounding error in the line search)
- fix bug: BFGSmin, BFGSmax, BFGScmin, BFGScmax, NRmin and
  NRmax could return a criterion value that did not
  correspond exactly to the final parameter vector
- Delete some unused variables flagged by clang
- markdown formatter: handle bulleted lists not preceded
  by a blank line
- macOS: add installer packages for gretl_edit
- PairPlot addon: upgrade to PDF documentation
