Double vs Elgg: at a glance
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 Elgg?
Elgg ships paired 7.1.2 and 6.3.9 patches: both branches stay in maintenance mode.
Elgg is a mature open-source PHP framework for self-hosted community platforms. The 7.0 major shipped in May 2026, and 7.1.0 in September added invitation-only groups, header images for generic entities and a MariaDB recommendation. 7.1.1 fixed profile access display and trash recovery, and on October 21 Elgg shipped 7.1.2 and 6.3.9 together, both with no release notes beyond the contributor list.

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.
Elgg
5.0COLLAB
Elgg ships paired 7.1.2 and 6.3.9 patches: both branches stay in maintenance mode.
◆ Current state
Elgg is a mature open-source PHP framework for self-hosted community platforms. The 7.0 major shipped in May 2026, and 7.1.0 in September added invitation-only groups, header images for generic entities and a MariaDB recommendation. 7.1.1 fixed profile access display and trash recovery, and on October 21 Elgg shipped 7.1.2 and 6.3.9 together, both with no release notes beyond the contributor list.
◆ Where it's heading
Elgg follows a predictable cadence: a feature minor, then single-digit patch releases, with paired backports on the 6.3 branch. The 7.1 features centred on finer access control and generic entity handling, and the follow-up patches stay in those areas. The project favours stability over pace.
◆ Prediction
More 7.1.x patches are likely, released in pairs with 6.3.x as happened again today. The entries give no signal about what a 7.2 would contain.
