This file details the changes between Scilab 2026.0.0 (this version) and the previous 2025.1.0 stable release.
For changelogs of earlier releases, please see Scilab 2025.1.0.
Summary:
For a high-level description of the main new features in this release, please consult the homepage of the embedded documentation, available by simply typing doc in the Scilab console.
cdftnc(): Cumulative distribution function of the non-central student's T distribution.dbscan(): Density-based clustering.enumeration(): Get the enumeration of a classdef or an object.estimate_bandwidth(): Estimate an appropriate bandwidth for mean shift clustering.gallery(): Generate test matrices.gradient(): Compute numerical gradient.isa(): Check variable type.meanshift(): Mean shift clustering algorithm.methods(): Get accessible methods of a classdef or an object.properties(): Get accessible properties of a classdef or an object.sortrows() : Sort rows of a vector, matrix, table, or timeseries.spset(): Set non-zero entries of a sparse matrix.host() has been rewritten and is now used as backend for all other functions that perform system calls (dos(), unix(), unix_g(), unix_s(), unix_w(), and unix_x()) which are now obsolete.intersect() now manages duration, datetime, table, and timeseries types.lib() can now load a library without exposing its symbols (default behavior remains unchanged).setdiff() now manages duration, datetime, table, and timeseries types.table() and timeseries() now manage integers.union() now manages duration, datetime, table, and timeseries types.duration(), calendarDuration(), datetime(), timeseries(), and table() functions.classdef, enumeration, properties & methods keywords.end keyword can now be used to specify the last row/column index of an array, similarly to $.All these functions and features will be removed in Scilab 2026.1.0 (May 2026):
demo_begin(): Please use exec() instead.demo_choose(): Please use x_choose() instead.demo_compiler(): Please use haveacompiler() instead.demo_end(): Please use exec() instead.demo_file_choice(): Please use x_choose() instead.demo_function_choice(): Please use x_choose() instead.demo_run(): Please use exec() instead.All these functions and features will be removed in Scilab 2027.0.0 (October 2026):
dos(): Please use host() instead.unix(): Please use host() instead.unix_g(): Please use host() instead.unix_s(): Please use host() instead.unix_w(): Please use host() instead.unix_x(): Please use host() instead.The following functions have been removed:
