What is Double?

Ask Double can now read and post in Microsoft Teams on an accountant's behalf.

Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 22 release connects Ask Double to Microsoft Teams, where it can read chats and channels and send messages as the user after confirmation, and lets it draft executive summaries and act on batches of tasks. Bookkeeping work continues alongside: customer-level and whole-P&L allocations, partial fixed-asset disposals and reminders for every open client request. The week before brought Ask Double to Xero and Consolidations in beta.

What is Prowlarr?

Prowlarr 2.6 ships active bi-weekly patches as the indexer management layer for the *arr ecosystem.

Prowlarr is on its 2.6 release series, shipping patch releases approximately every one to two weeks. The releases contain targeted fixes for indexer compatibility, authentication handling, and protocol-level bugs (HTTP Basic Auth, Happy Eyeballs logging). As the indexer proxy for Sonarr, Radarr, Lidarr and related tools, Prowlarr's changes are largely operational fixes that improve the reliability of its centralized indexer management.

Ask Double can now read and post in Microsoft Teams on an accountant's behalf.

◆ Current state

Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 22 release connects Ask Double to Microsoft Teams, where it can read chats and channels and send messages as the user after confirmation, and lets it draft executive summaries and act on batches of tasks. Bookkeeping work continues alongside: customer-level and whole-P&L allocations, partial fixed-asset disposals and reminders for every open client request. The week before brought Ask Double to Xero and Consolidations in beta.

◆ Where it's heading

Two tracks run in parallel: fuller QBO bookkeeping coverage and an AI layer that reaches across a firm's tools. Teams is the first connector in these entries where Ask Double writes outside the ledger, not just reads, with a confirmation step as the guardrail. The assistant is becoming the way staff operate Double in bulk, from tasks to reports.

◆ Prediction

Expect more write-capable connectors with the same confirm-before-send pattern, and Ask Double on Xero gaining write actions after its read-only beta.

Prowlarr
COLLAB
5.0

Prowlarr 2.6 ships active bi-weekly patches as the indexer management layer for the *arr ecosystem.

◆ Current state

Prowlarr is on its 2.6 release series, shipping patch releases approximately every one to two weeks. The releases contain targeted fixes for indexer compatibility, authentication handling, and protocol-level bugs (HTTP Basic Auth, Happy Eyeballs logging). As the indexer proxy for Sonarr, Radarr, Lidarr and related tools, Prowlarr's changes are largely operational fixes that improve the reliability of its centralized indexer management.

◆ Where it's heading

The release cadence is consistent and the scope is narrow — Prowlarr ships when bugs are fixed, not on a feature roadmap schedule. The 2.6.0 version bump is recent (July 26), suggesting a feature addition drove the minor version increment, but the subsequent patches return to pure maintenance. No major capability expansion is signaled in the recent changelog window.

◆ Prediction

Prowlarr will continue its reactive patch cadence as indexer compatibility issues surface. A 2.7.x release with new indexer support or protocol improvements is the most likely next feature milestone, following the same pattern as 2.5→2.6.
