Option to print the mean response on concentration-response and residual plots.
Various bug fixes and UI enhancements.

Added the Durbin-Watson test for autocorrelation in linear regression.
Added a Filter Search toggle that narrows the record list as you type (e.g., “2403” finds tests in March 2024; “240325” finds March 25, 2024).
Many bug fixes and UI enhancements.

The front-end is now code-signed; with Access 2016 build 2212 or higher, CETIS no longer needs to be in Trusted Locations.

Full compatibility with non-English regional settings; sorting/filtering fixes on the Global Test List.

Improved Intensive Repair utility for database corruption; repair logging; new rounding and exporting options.

Common questions about updates

Updates are free on request for purchases made less than one year ago. After a year, a reasonable fee may apply for major updates.

A numerical update (e.g., v2.0.x to v2.1.x) changes the back-end database and may require an additional file from Tidepool. A letter update changes only the front-end and is minor in scope.
