Release Notes for 2026

mm-dd

07-02

  1. Advance to cppad_mixed-2026.7.2. This fixes a compile error when using g++ version 16.1.1 20260515.

  2. The development tools were moved from the bin subdirectory to the tools subdirectory. This was done for two reasons: it is a more standard choice for this directory and it makes tools/path_tools.sh less problematic (see below).

  3. Advance the dock_dismod_at dismod_at_version from 2026.0.1.to 2026.7.2. Instructions were added at the link above for getting older versions of dismod_at using dock_dismod_at.sh.

  4. Note that if you execute source tools/tools_path.sh the local subdirectory tools will be added to you path; e.g., you can use check_all.sh instead of tools/check_all.sh .

04-14

Advance to cppad_mixed-2026.4.14. This ensures that the cppad library is dynamic (not static) except in the Windows system case. It also makes the metis package available to the sparse linear algebra solver used by the optimizer in cppad_mixed.

04-04

Change the dismod_at source code and documentation to use 4 spaces for one tab; i.e., one level of indentation. This used to be 3 spaces because that works well with rst lists (the dismod_at documentation uses rst), but 4 spaces is the most common choice used by programmers.

03-27

Change bin example_install.sh so that it automatically installs numpy, matplotlib, scipy and sqlite on redhat and debian systems. (These are required to test dismod_at which is part of the install process.)

01-11

Advance the dock_dismod_at dismod_at_version from 2025.10.17 to 2026.0.1 and at_cascade_version from 2025.10.18 to 2026.0.0.

01-10

API Change : The 2026 release of cppad_mixed changed the name of its mater branch to main. This broke old versions of dock_dismod_at.sh; see Patching Old Versions .

01-09

  1. There was a mistake in the search for CHOLMOD during the cmake command on windows. This has been fixed.

  2. Create the dismod_at-2026.0.1 release.

01-07

The changes are included in the 2026.0.0 version of dismod_at:

  1. Advance to using cppad_mixed-2026.0.0. (This also advance cppad to version 20260000.0 .)

  2. Report an error if the sqlite libraries are not found during the dismod_at cmake command. This makes it easier for the user to know to install these libraries.

  3. The bin/example_install.sh script was not terminating with an error code when one of the checks failed. This has been fixed.

  4. Fix some spelling errors found by the typos package.

  5. Create the dismod_at-2026.0.0 release
