What is Double?

Double is turning its accounting assistant into the way the work gets done

Double ships weekly, and nearly every release extends Ask Double rather than the surrounding application. In the last two months it has learned to build workpapers by reconciling accounts against supporting documents, import accruals, create and manage client metrics through the MCP and API, take voice input, and — in private beta — reach into Slack, Notion, and HubSpot. The non-assistant work fills in what firms need to trust that: role-based restrictions on editing client properties, and check transactions in AI Transactions.

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.

Double is turning its accounting assistant into the way the work gets done

◆ Current state

Double ships weekly, and nearly every release extends Ask Double rather than the surrounding application. In the last two months it has learned to build workpapers by reconciling accounts against supporting documents, import accruals, create and manage client metrics through the MCP and API, take voice input, and — in private beta — reach into Slack, Notion, and HubSpot. The non-assistant work fills in what firms need to trust that: role-based restrictions on editing client properties, and check transactions in AI Transactions.

◆ Where it's heading

The assistant is moving from answering questions to performing the billable work — tie-out, accrual setup, metric standardization across a whole book of clients. Each release pairs that with an access or permissions control, which is the pattern of a vendor that knows the objection is liability rather than capability. The accounting engine itself keeps advancing underneath, most recently with prepaid contracts paid in installments.

◆ Prediction

Given the review-and-signoff question these features raise, the likely next step is an approval or audit trail around what Ask Double produces rather than another task it can perform.

F6.3

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.
