What is File Browser?
File Browser is shutting down — the repo archives on 2026-09-01 and no security fixes follow.
The project spent July shipping a rapid series of hardening releases — path canonicalization before access checks, atomic user provisioning, TUS upload length enforcement, download-permission gates, case-folded home directory collisions, several GHSA-tracked share and auth advisories — and then announced it was winding down. 2.63.23 is the last planned release; the repository archives on 2026-09-01.
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.

File Browser is shutting down — the repo archives on 2026-09-01 and no security fixes follow.
◆ Current state
The project spent July shipping a rapid series of hardening releases — path canonicalization before access checks, atomic user provisioning, TUS upload length enforcement, download-permission gates, case-folded home directory collisions, several GHSA-tracked share and auth advisories — and then announced it was winding down. 2.63.23 is the last planned release; the repository archives on 2026-09-01.
◆ Where it's heading
The shape of the final weeks tells the story: almost every commit was a scope-escape or permission-bypass fix, which is a heavy load for a Go binary that many people expose directly to the internet. Rather than keep absorbing that, the maintainers are stopping. Existing releases and Docker images stay online, but from September there is no one fixing the next advisory.
◆ Prediction
Existing deployments keep working and keep accumulating unpatched vulnerabilities; expect the community to consolidate around a fork or one of the existing alternatives before the archive date.
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.
