Standing notes

abra recipe upgrade cannot parse the version-YYYY.M.D tag format of the cryptpad/cryptpad image, so the app image is bumped by hand; the nginx sidecar is what abra recipe upgrade actually moves.
Only use tags in the canonical version-YYYY.M.x scheme. The opendesk-YYYY.MM.DD tags on Docker Hub are openDesk-specific builds, not newer CryptPad releases — e.g. opendesk-2026.08.04 (built 2026-08-04) still contains CryptPad 2026.5.1 in /cryptpad/package.json.
CryptPad's GitHub releases and Docker Hub tags are not simultaneous: 2026.10.0 was released 2026-10-21 but version-2026.10.0 was still absent from Docker Hub on 2026-10-23. Re-check the Docker Hub tags page before treating a GitHub release as available for the recipe.
The 2026.10.0 release is a breaking one for the recipe: full server rewrite (separate cryptpad-server package), split config.js → config/infra.js (public origin/ports move), one proxy port for HTTP + websocket (no separate 3003 websocket port), and SSO plugin v1.0.0 required. Read its upgrade notes before attempting that bump.
nginx is HTTP/1.1-only here (sidecar on :8083, proxy_http_version 1.1), so HTTP/2/3 CVE changes in nginx releases generally don't affect this recipe — but still note them.
