Version History

0.3.0.0 (May 2025)

One new titration type was added (titration with volume change, as in real life). In addition, some remaining issues with regard to DPI-scaling were fixed.

0.2.4.4 (March 2025)

Two new titration types were added (replace titration and chemically correct titration). In addition, the main window is now adjusted properly if you move it to a monitor with a different DPI-scaling. Finally, the Facebook-link was replaced by a BlueSky-link.

0.2.2.0 (January 2025)

A new titration type (double titration) was added. In addition, the titration interface was improved, and a few minor (?) bugs in titrations were fixed.

0.2.1.18 (December 2024)

A bug was fixed in titrations with equilibrium constants.

0.2.1.16 (November 2024)

A bug was fixed in the update procedure.

0.2.1.14 (November 2024)

This version contains the first titration type. Others will follow soon! In the screenshot-section, you can see how it looks like.

0.2.1.12 (February 2024)

Three bugs fixed which could cause program crashes.

0.2.1.10 (December 2023)

0.2.1.8 (December 2022)

MSA-radii updated and a few bug fixes.

0.2.1.6 (August 2022)

MSA-radii updated, atomic weights checked and a few bug fixes.

0.2.1.4 (May 2022)

A few bug fixes.

0.2.1.3 (January 2022)

A few bug fixes.

0.2.1.0 (December 2021)

Version 0.2.1.0 has now extended MSA-information; the MSA-info is also shown for salts for which no complexes are included in the database. In addition two bugs were fixed; one displaying incorrect values when including organic complexation; one displaying info from previous runs in 'other info'.

0.2.0.0 (November 2021)

A bug in the 64-bits version was fixed. When organic complexation was included, incomplete results were diplayed.

0.1.0.19 (August 2021)

The 64-bits version now enables downloading and viewing of the manual and the database document from within the program.

2014.0.9.2 (30 March 2014)

Printing output has been implemented (for an example output file click here; pdf-file, opens in separate window).
A different way of updating the program has been implemented (now works fine in Windows 8).

2014.0.9 (19 January 2014)

The interface was completely redesigned.
The code was optimised and compiled with a different compiler.
The program is much faster and smaller than CHEAQS Pro was.
The help-system is upgraded to the .CHM-format and also completely redesigned.
User changes to the database can now be preserved when the master-database is upgraded.
Editing input is now yet easier and more easy-reference. Cations and ligands can be shown alphabetically or in order of periodic table.
Output can be viewed in entirely new interface, saved, opened later, exported to .CSV or .XML-format for exchange with spreadsheet-programs like EXCEL ® or Open Office.
Documentation (including a manual) is available.
More settings are remembered within and across sessions.

Some features that are included in CHEAQS Pro are not yet implemented in CHEAQS Next, such as calibrations.
