SumDoc version history

Each line below is a change visible in the product itself. Versions run from newest to oldest.

The top entry can be ahead of what’s actually deployed: the changelog grows as the release comes together, and deployment is a separate step. Which version is available right now is shown in the release catalog, linked from the installation page.

The version number is made up of the year, the quarter, and the patch number within the quarter: in 2026.3.4, that’s the fourth patch to the third-quarter 2026 release. The patch count restarts every quarter, so 2026.3.19 is followed by 2026.4.0, not 2026.3.20.

Downloadable filenames add one more part to the number — a running build number, for example 2026.3.4.25. It doesn’t affect version comparison and exists to distinguish files of the same version built at different times. Release candidates and test builds carry a suffix: 2026.4.0-rc1, 2026.4.0-beta1.

The application checks the installed version against what the update channel offers, and prompts you to update when a newer one comes out. You can check manually with the “Check for Updates…” menu item.

Total releases: 64, counted from the 2023.2 quarter.

Before switching to quarterly numbering

The earliest builds shipped under a different kind of number and went out as alpha — for demonstration, not for production use. There’s no separate changelog for them: back then, the product changed faster than versions were released.
