Contractbook hands the AI's extraction prompts over to the customer
Contractbook publishes short, emoji-headed notes, most of them arriving in same-day batches. The August 3 batch covered admin permission maps across spaces, OTP two-factor at login, calculations inside forms, a rebuilt search results page, and a new model behind AI data extraction. This release opens the default data fields themselves: the prompts behind each AI-detected field can be rewritten or renamed per contract type.
Nextcloud runs three LTS branches in parallel, shipping bug fixes and quiet performance wins.
Nextcloud is simultaneously maintaining three major release lines (32.x, 33.x, 34.x), publishing patch updates every few weeks. Recent work fixes file-sharing edge cases, corrects share permission logic, and patches OCM federation bugs. Performance work targets group membership lookups, swapping full group-object fetches for leaner ID-only queries across branches.

The AI extraction layer has been treated as a black box that Contractbook tunes and customers accept. Editable prompts break that — accuracy on a customer's own contract vocabulary becomes something they adjust rather than file a ticket about. It fits the wider pattern of the last few releases, where admin surfaces (space access maps, group permissions, contract-type management) are being built so companies can configure what used to be product defaults.
Once prompts are editable per contract type, per-field extraction quality becomes visible and arguable, so expect some form of confidence indicator or review step on extracted data next.

The three-track maintenance cadence signals a hardening phase following v34's release, prioritizing stability over new surface area. OCM fixes accumulating across branches suggest cross-instance federation use is growing and generating real-world bug reports. If this pattern holds, a v35 feature push is the next inflection point — the current batch is largely invisible to end users.
The next meaningful surface change will likely come with v35 feature work; the cross-branch group-query performance push and OCM federation fixes hint that enterprise scale and cross-instance collaboration are the focus areas going into the next major.
