Recession bands and the time series G.U.I.
by climnios＠providence.edu
Hello - just downloaded the latest iteration in case that may have solved my issues, but alas, it's still there.
I do very much enjoy placing the NBER recession bands in my plots, but I noticed as of late that this "push button" option is no longer available in the plot G.U.I.
I suppose I can do this by hand through the command line, but before going down that route I wanted to check in with the group to see if this functionality has been deprecated.
Thanks either way,
//Chris

Package updates (April 2026)
by Riccardo (Jack) Lucchetti
Dear all,
this message is to inform the community about the activity in our
function package repository: during the month of April 2026, 2 packages
were updated to a new version:
"color_xy", by myself (color xy plot for time series )
"Winters", by Ignacio Diaz-Emparanza and Allin Cottrell (Winters
forecasting method)
The most important update is, by far, the one to the "Winters" package:
it was prompted by a message that ramakrishnasalagrama(a)gmail.com posted
to the list two months ago on his difficulties to replicate some results
from Rob Hyndman. So Allin wrote some cool improvements to old code by
Ignacio, and here we are, with a brand new version. (And yes, Hyndman's
example can be replicated now.)
As usual, update and enjoy!

gretl 2026b released
by Allin Cottrell
See https://gretl.sourceforge.net/
Here are the changes:
2026-04-30 version 2026b
- new function which() to determine which elements of a
given matrix satisfy a specified condition
- new function fols() for factorized least squares
- new function tsolvepd() for solving Toeplitz linear
systems when the Toeplitz matrix is known to be symmetric
and positive definite
- probability distribution functions: add support for the
truncated normal distribution
- "join" command: fix possible crash on joining data from
two binary gdtb data files in succession
- correlation matrix plot: use graph-names as set by the
"setinfo" command if available
- "add" and "omit" commands with --auto option: attach to
the augmented or reduced $model bundle a list giving the
order in which regressors were added ("add_order") or
omitted ("omit_order")
- "var" command with --lagselect option: show the LR test
P-value for the null of lag order 0
- "vecm" command: in the vecm_info bundle in the $system
accessor we now provide new matrices: "long_run"
(Johansen's C), "cov_long_run" (the covariance of vec(C))
and "se_long_run" (standard errors of the elements of C),
along with additional documentation in the User's Guide
- "foreign" command block: support the --send-data option
when executing a Python script, via Pandas
- "panplot" command: correct suport for the --font option
- matrix "slicing": correct handling of an empty selection
vector, and sypport use of row and column names when
indexing into matrices
- script editor: handle "doc strings" in hansl functions
via "question mark-click"
- geoplot addon: document the cbrange option
- User's Guide: improve documentation of string literals
- GUI: /View/Correlations now shows nonparametric option
- GUI: Augment tooltips for model selection dialog buttons
- GUI: "View code" for function packages: preserve inline
comments
- GUI: fix broken display of complex matrices
- GUI: enhance searching of gretl-curated data files
- GUI: fix handling of scalar arguments in the dialog box
for calling function packages
- GUI: "ui-maker" for functions packages: support setting
a run-time default for a boolean argument
- GUI: fix breakage in Command Log on Windows and macOS
- GUI: fix breakage in string argument selector for
function packages on 32-bit Windows (GTK2)
- launching of gnuplot via gretl: respect the GNUTERM
environment variable on Linux, if present
- Windows ARM64 build: include MPI and make available an
ARM64 build of X-13ARIMA-SEATS (x13as)
- Mac builds: update GTK3 to version 3.24.52
