CryptPad vs Mattermost

CryptPad releases in named seasonal batches — Winter 2026.2.0, Spring 2026.5.0 — each followed by one or two small fix releases, then a long quiet stretch. The two substantive releases in this window both center on upgrading bundled upstream editors: OnlyOffice 9 for the office apps in February, Drawio 29 for the Diagram app in May, the latter switching to an infinite-canvas sketch theme by default with a switcher for the older mode. Everything else is fixes, translations, accessibility and locale additions, and websocket and pinning leak repairs. Since May the only entry is an opendesk-tagged build that suppresses donation prompts when CryptPad runs inside an integration.

This reads as a small team maintaining a broad end-to-end encrypted suite rather than pushing into new capability. Progress arrives largely through the editors CryptPad wraps, with its own work concentrated on the collaboration layer around them — history browsing extended to office documents, drive tree, forms, moderation tooling. The opendesk build points at where distribution is actually going: CryptPad embedded as a component of a larger sovereign workplace stack, with donation appeals turned off because in that context someone else owns the user relationship.

Expect the next seasonal release to continue the pattern — another upstream editor bump plus accumulated fixes — and more integration-specific adjustments as embedded deployments grow. The three-month gap since the Spring line suggests the next batch is still some way out.
