Release Notes for 2025

mm-dd

10-18

Advance dismod_at_version from 2025.9.26 to 2025.10.17 and at_cascade_version from 2025.10.15 to 2025.10.18.

10-16

It used to be that python_main would put markers in the log table for the begin and end of the python commands. In the case where the python commands were called from python, instead of through the python main program, there were no begin and end markers. This has been fixed and now the begin and end markers are written by the following python functions: db2csv_command , perturb_command , plot_data_fit , plot_rate_fit , and modify_command . Note that the modify command is deprecated.

10-15

Advance at_cascade_version from 2025.9.26 to 2025.10.15.

10-12

The :ref:Logging Python Commands wish list item was added. (It was completed by the changes on 10-18 above.)

09-26

Advance bin/get_cppad_mixed.sh version from 2025.6.6 to 2025.9.19. Advance the dock_dismod_at dismod_at_version from 2025.8.21 to 2025.9.26 and at_cascade_version from 2025.8.21 to 2025.9.26.

09-22

Add the fit_var scale option to the predict command. In addition, create the user_predict_sample.py example which demonstrates it used.

08-21

Advance the dock_dismod_at dismod_at_version from 2025.7.31 to 2025.8.21 and at_cascade_version from 2025.8.1 to 2025.8.21.

08-19

Change the way the dismod_at executable creates tables so that it inserts at most 1000 rows at a time. This was done to avoid the following limitation: ‘The maximum number of bytes in the text of an SQL statement is limited to SQLITE_MAX_SQL_LENGTH which defaults to 1,000,000,000.’

08-01

Advance the dock_dismod_at dismod_at_version from 2025.7.6 to 2025.7.31 and at_cascade_version from 2025.7.10 to 2025.8.1.

07-31

  1. The documentation for log table message type command has been improved.

  2. The documentation for log.csv was improved to menton that there will be a begin db2csv without the corresponding end db2cav at the end of log.csv .

API Change

The log table end command message_type has been changed so that the entire command is included in the messages; i.e., it is the same as the corresponding begin with begin replaced by end. It used to be that just end followed by the command name was included in the message. For example, in the user_re_scale.py example, the code

   assert log_table[fit_log_id + 1]['message'] == 'end fit'

was changed to

   assert log_table[fit_log_id + 1]['message'] == 'end fit both'

Note that it could have also been changed to

   assert log_table[fit_log_id + 1]['message'].startswith( 'end fit' )

07-11

Advance the dock_dismod_at dismod_at_version from 2025.6.6 to 2025.7.6 and at_cascade_version from 2025.6.5 to 2025.7.10.

07-06

There was a problem with the change on 06-17 when all the data was zero. In this special case the plot is now done in linear instead of log space. (This case was not handled properly before the change on 06-17.)

07-05

Add the censor_asymptotic method to the sample command. This ensures that the samples satisfy the variable lower and upper limits.

06-17

The data fit plots scaling of the model and measurement values is in log scale using the median of the data. This would create a problem when more than half the data had value zero. This has been fixed by using the median of the data greater than zero.

06-06

  1. Fix bug in commit on 06-05 by changing CHOMOLD -> CHOLMOD in CMakeLists.txt. This caused the following error on some systems:

    -- Cannot find CHOMOLD.pc file

  2. Advance to cppad_mixed-2025.6.6.

  3. Advance the dock_dismod_at dismod_at_version from 2025.4.16 to 2025.6.6 and at_cascade_version from 2025.2.7 to 2025.6.5 .

06-04

Printing the actual condition number for an asymptotic statistics calculation was added; see asymptotic_rcond_lower .

06-03

Add a lower bound for the reciprocal condition number of the approximation for the asymptotic information matrix; asymptotic_rcond_lower .

05-22

  1. The example_install.sh script was sometimes writing example_install.log and example_install.err to the directory above the top source directory. This has been fixed.

  2. There was a problem with the change on 05-09 below: add_to_set was missing during the cmake command. This has been fixed.

05-09

  1. Advance to cppad_mixed-2025.5.8.

  2. There is a bug in the install of suitesparse on Fedora-42 that prevented dismod_at from installing. A temporary fix was used to get around this. Search for FIND_PACKAGE(CHOLMOD) in the top level CMakeLists.txt file to see more discussion about this.

05-06

  1. Add install_conda instructions. This is the first install of dismod_at that works on windows.

  2. Deprecate dismodat.py and replace it with dismod-at .

  3. Add a table of commands to the python main program documentation.

04-17

Advance the dock_dismod_at dismod_at_version from 2025.2.7 to 2025.4.16.

04-16

The system_command_prc routine was improved so that it captured and reported exceptions during its call to subprocess.run as if they were messages on stderr.

04-12

  1. The name dismod-at can be used in place of dismodat.py. The current plan is to deprecate dismodat.py and only use it for testing.

  2. The number of attempts in balanced_pair_xam test was increased from two to three to reduce the chance of a random failure.

04-11

The test/user/bound_random.py case was failing on windows. Change the derivative test for this case to adaptive so that it is the same on windows and linux. Also decrease the width of the feasible region so that derivative testing does not use a point where the objective can’t be evaluated.

04-08

The error messages for invalid values in the option_table were improved. To be specific, the option name was included in the messages.

04-03

Some of the C++ connections to the data base were not properly closed. This caused a failure during testing on windows systems and has been fixed.

03-25

  1. Change bin/user_test.sh to bin/user_test.py so that it can be used in Dos, Macos, and Linux.

  2. Fix some no-standard constructs in logical expressions; e.g., change not std::isnan to ! std::isnan .

  3. Fix ‘possibly dangling reference to a temporary’ in subset_data.cpp

    and child_data_in_fit.cpp .

02-07

Advance the dock_dismod_at dismod_at_version and at_cascade_version to 2025.2.7.

02-06

Add the max_fit_parent option to the hold_out command.

02-04

  1. Advance to cppad_mixed from 2025.0.0 to 2025.2.2. This has improvements to the install procedure that were made to facilitate including cppad_mixed in conda-forge.

  2. Advance the dock_dismod_at dismod_at_version and at_cascade_version to 2025.2.4.

02-02

The math_ode page was moved to diff_eq . It was also improved and extended to include discussion of the partial and stochastic differential equation.

01-15

Start the 2025 stable versions of dismod_at; see the new Versions table. A release for 2025 has the stable version 2025.0.number where number is the release number. Only bug fixes, not new features, are added between release numbers. The dock_dismod_at.sh version of dismod_at was advanced to 2025.0.0; see dismod_at_version . The dock_dismod_at.sh version of at_cascade was advanced to 2025.0.0; see at_cascade_version .

This change has broken old web links to the dismod_at documentation. An old link of the form

      https://dismod-at.readthedocs.io/html_file_name

has the following form in the latest documentation:

      https://dismod-at.readthedocs.io/latest/html_file_name

and the following for in the 2025 stable documentation:
