What is grommunio?
grommunio's feed publishes release pointers only; the changes themselves live on GitHub.
The crawled feed carries twelve release-note stubs spanning August 2021 to June 2026, each the same 134-character sentence directing readers to GitHub for the detailed logs. Version 2026.06.1 is the most recent. Nothing in the feed states what changed in any release, so the platform's current capability surface cannot be read from this source.
What is Respond.io?
respond.io is widening the inbox again after landing Copilot and metered AI credits.
Early August was respond.io's AI moment: Copilot arrived in every workspace with an agent builder that drafts and test-runs an AI agent, and AI Credit On-Demand started billing overage instead of cutting AI off at the plan limit. Since then the work has moved back to the inbox itself - a Microsoft 365 and Outlook email channel, TikTok Business Messaging for US-registered accounts, conversation collaborators who can act without reassignment, a missed-call follow-up template, and now a contact's Google Calendar meetings shown beside the conversation.

grommunio
0.0COMMS
grommunio's feed publishes release pointers only; the changes themselves live on GitHub.
◆ Current state
The crawled feed carries twelve release-note stubs spanning August 2021 to June 2026, each the same 134-character sentence directing readers to GitHub for the detailed logs. Version 2026.06.1 is the most recent. Nothing in the feed states what changed in any release, so the platform's current capability surface cannot be read from this source.
◆ Where it's heading
The only signal available is cadence, and it is thin and irregular: twelve published notes across roughly five years, with 2023.11.x, 2025.01.x and 2026.06.1 as the visible markers. That is a release-notes page maintained as an index rather than a changelog. Reading direction from grommunio would require the GitHub logs these notes point at.
◆ Prediction
Expect the next entry to be another dated pointer of the same form. Whether grommunio's real release cadence matches this feed cannot be determined from what is published here.
Respond.io
7.5COMMSSUPPORT
respond.io is widening the inbox again after landing Copilot and metered AI credits.
◆ Current state
Early August was respond.io's AI moment: Copilot arrived in every workspace with an agent builder that drafts and test-runs an AI agent, and AI Credit On-Demand started billing overage instead of cutting AI off at the plan limit. Since then the work has moved back to the inbox itself - a Microsoft 365 and Outlook email channel, TikTok Business Messaging for US-registered accounts, conversation collaborators who can act without reassignment, a missed-call follow-up template, and now a contact's Google Calendar meetings shown beside the conversation.
◆ Where it's heading
The pattern is accumulation around a single conversation view rather than depth in any one channel. Each release adds either a place messages arrive from or a piece of context that used to require another tab, and most ship as pre-built workflow templates or read-only panels rather than as new configuration for an admin to learn. With AI usage now metered rather than capped, every surface feeding the inbox is also more material for agents billed against those credits - the channel expansion and the AI pricing change point the same way.
◆ Prediction
The calendar integration is read-only and sends users to Google to create or edit, which is the obvious next gap to close. Beyond that, expect channel availability to keep opening region by region on the TikTok pattern rather than new channel types arriving.
