What is AFFiNE?
Dependency bumps dominate the canary train; the one real change is blob sync.
AFFiNE publishes two parallel release trains and this window catches both: date-stamped canary builds and a v0.27.x beta tag. Four of the six most recent entries are dependency chores — GitHub Actions bumps for setup-python and cache, and a RevenueCat iOS SPM version raise. The single substantive change is a server-side blob sync improvement that standardizes presigned URL configuration across AWS S3 and Cloudflare R2, and it appears twice because the same pull request lands on both trains.
What is Contractbook?
Contract automation grows up: admin permission maps, 2FA, and forms that do their own arithmetic.
Contractbook released a batch of six changes on a single day covering three areas at once. Administration gets a company-wide Spaces access page answering who can reach which space and with what permission, plus OTP two-factor authentication at login. Contract creation gets calculation fields in forms that compute totals and pro-rated amounts and insert them into the document automatically. The AI side gets a new extraction model and a dedicated place to manage AI upload contract types, with built-in defaults now editable per company.

AFFiNE

Dependency bumps dominate the canary train; the one real change is blob sync.
◆ Current state
AFFiNE publishes two parallel release trains and this window catches both: date-stamped canary builds and a v0.27.x beta tag. Four of the six most recent entries are dependency chores — GitHub Actions bumps for setup-python and cache, and a RevenueCat iOS SPM version raise. The single substantive change is a server-side blob sync improvement that standardizes presigned URL configuration across AWS S3 and Cloudflare R2, and it appears twice because the same pull request lands on both trains.
◆ Where it's heading
The engineering attention in this window is on storage plumbing rather than the editor: configurable presigning versus server-mediated proxying, plus tightened upload and multipart validation. That is self-hosting work, giving operators control over how blobs move between the app and their own object storage. Everything else here is automated maintenance, so the canary cadence reflects CI activity more than product movement.
◆ Prediction
Expect the storage configuration work to continue toward broader self-hosted deployment options, and expect the beta line to absorb the current canary changes as 0.27.4 stabilizes.
Contractbook
5.0COLLAB
Contract automation grows up: admin permission maps, 2FA, and forms that do their own arithmetic.
◆ Current state
Contractbook released a batch of six changes on a single day covering three areas at once. Administration gets a company-wide Spaces access page answering who can reach which space and with what permission, plus OTP two-factor authentication at login. Contract creation gets calculation fields in forms that compute totals and pro-rated amounts and insert them into the document automatically. The AI side gets a new extraction model and a dedicated place to manage AI upload contract types, with built-in defaults now editable per company.
◆ Where it's heading
The pattern is a product being fitted for larger customers: the access-visibility page is gated to Accelerate and Enterprise plans, group-level company permissions landed earlier in the year, and 2FA closes the obvious procurement objection. Meanwhile the AI features are moving from fixed behaviour toward configurable behaviour — extraction types are now a company's own list rather than the vendor's. Calculations remove the last common reason to edit a generated .docx by hand.
◆ Prediction
The admin thread points toward more permission surface — audit trails or per-space delegation would follow naturally from a page that already explains where each permission comes from. Nothing in these entries indicates how much extraction accuracy actually improved.
