What is AFFiNE?
AFFiNE's canaries stay on upkeep: a Swift Collections bump follows CVE and migration fixes.
AFFiNE ships a canary build almost daily, and nearly all of October has been dependency and infrastructure work. The newest, canary 915, bumps Apple's Swift Collections package to 1.7.4 for the native apps. Before it came a happy-dom code-execution CVE patch, payment-record repairs during a data migration, and non-root, read-only containers with multi-architecture Windows builds.
What is Contractbook?
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.

AFFiNE
5.0COLLAB
AFFiNE's canaries stay on upkeep: a Swift Collections bump follows CVE and migration fixes.
◆ Current state
AFFiNE ships a canary build almost daily, and nearly all of October has been dependency and infrastructure work. The newest, canary 915, bumps Apple's Swift Collections package to 1.7.4 for the native apps. Before it came a happy-dom code-execution CVE patch, payment-record repairs during a data migration, and non-root, read-only containers with multi-architecture Windows builds.
◆ Where it's heading
The feed reads like a team hardening the backend and toolchain ahead of a larger cutover: a payment-identity migration, stricter deployment defaults and steady Renovate bumps across web, server and native code. Feature work isn't visible in canaries this month; the last user-facing fix was October 12's blob-upload quota correction.
◆ Prediction
Expect the data migration to finish in the next canaries, followed by a stable release that bundles it; the entries don't show which user-facing feature is next.
Contractbook
5.0COLLAB
Contractbook hands the AI's extraction prompts over to the customer
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
