Release history latest · v2.1.7
  • Calculations validated against corresponding methods and packages in R; log-likelihood equations aligned with R and SAS. Supports fractional degrees of freedom for the Welch-Satterthwaite adjustment.
  • Now requires Access 2016 or higher (or current Microsoft 365) for code signing and reliable PDF generation.
  • Queries and reports re-engineered for faster generation and printing.
  • New print-queue system and a customized print dialog that remembers your printer selection and options.
  • 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.
  • Descriptive statistics are now stored rather than recalculated at report time, speeding report generation.
  • Encrypted license now stored in the CommonData folder so CETIS is available to all users without elevated privileges.

  • 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.
  • Offered as 32-bit or 64-bit. Graphics Server control replaced by the TeeChart AX control for improved graphing; 95% confidence regions shown as shaded areas.
  • Moved to the accdb/accde format for improved password protection and encryption; redesigned interface; redesigned main form showing all information at once; improved import and database-repair utilities.

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.

Minor letter updates are generally not broadcast. Bookmark this page and check back.
