Double vs xaringan: at a glance
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 xaringan?
xaringan has settled into theme upkeep and Pandoc-era compatibility patches.
The recent window is thin: 0.31 is a roxygen documentation change made to satisfy a CRAN complaint, 0.30 refreshes the Rutgers CSS theme and fixes `inf_mr()` against hashed URLs, 0.29 is an internal adjustment tracking changes in the servr package. Earlier releases in the window carry the actual features — title-slide element classes, child-document recompilation, self-contained audio and video embedding, and screen-reader shortcut conflicts resolved for JAWS.

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.
xaringan
0.0COLLAB
xaringan has settled into theme upkeep and Pandoc-era compatibility patches.
◆ Current state
The recent window is thin: 0.31 is a roxygen documentation change made to satisfy a CRAN complaint, 0.30 refreshes the Rutgers CSS theme and fixes `inf_mr()` against hashed URLs, 0.29 is an internal adjustment tracking changes in the servr package. Earlier releases in the window carry the actual features — title-slide element classes, child-document recompilation, self-contained audio and video embedding, and screen-reader shortcut conflicts resolved for JAWS.
◆ Where it's heading
Development has slowed markedly: 0.29 through 0.31 span February 2024 to August 2025 and none of them add anything a slide author would notice. The package's live surface is now community-contributed university themes and its coupling to Yihui Xie's servr, which supplies the live-preview machinery. This is a stable tool being kept working, not one being extended.
◆ Prediction
The next release is most likely another compatibility or CSS-theme change; nothing in the window suggests new authoring capability is coming.
