What is Paperless-ngx?
Paperless-ngx shipped its 3.0 rewrite, then spent a week putting out the fires.
3.0.0 landed on July 22 after a long beta, carrying both the largest feature set in the project's history and nine breaking changes. The five releases since are pure repair: a broken migration in 3.0.1 that forced an immediate 3.0.2, then three patch rounds covering OCR skipping, permission-filtered dedup, Gotenberg conversion, email date parsing, AI suggestion caching and search index edge cases. The pace tells you 3.0 shipped into real deployments fast.
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.

Paperless-ngx shipped its 3.0 rewrite, then spent a week putting out the fires.
◆ Current state
3.0.0 landed on July 22 after a long beta, carrying both the largest feature set in the project's history and nine breaking changes. The five releases since are pure repair: a broken migration in 3.0.1 that forced an immediate 3.0.2, then three patch rounds covering OCR skipping, permission-filtered dedup, Gotenberg conversion, email date parsing, AI suggestion caching and search index edge cases. The pace tells you 3.0 shipped into real deployments fast.
◆ Where it's heading
The project has moved from a document scanner-and-tagger to a document platform with AI in the core: Paperless AI, remote OCR via Azure, a document parser plugin framework, tantivy replacing Whoosh for search, file versions and sharelink bundles. The breaking changes are the other half of that story — dropping API v1, Python 3.10, document encryption and the old consumer clears the decks for that platform. Recent patches keep touching LLM plumbing, including passing output language into chat and adding docstrings so the classifier reads better as an LLM tool.
◆ Prediction
The 3.0.x patch cadence looks set to run at least another round or two — 3.0.5 is still landing search-compatibility and AI-suggestion fixes rather than tapering. Feature work resuming before that queue empties would be the surprise.
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.
