What is Kayako?
Kayako's public changelog has been silent since mid-2022 — the radar is showing a stalled product.
Kayako has not posted a public changelog entry since June 2022. The most recent communication was a CEO apology over a performance incident and a series of link-only release-notes posts pointing to a Help Center article. The visible operational picture is an established customer-support product no longer broadcasting product motion.
What is Respond.io?
Respond.io upgraded its AI Agents to GPT-5.6 and added TikTok Business Messaging for US accounts.
Respond.io is shipping across three tracks simultaneously: AI Agent improvements (GPT-5.6 model upgrade, pre-publish instruction review), channel expansion (TikTok Business Messaging for US, Microsoft 365/Outlook email), and workflow automation (missed call auto-follow-up, Google Calendar integration). The status persistence fix — keeping agents online as long as the tab is open — addresses a real reliability concern for teams that rely on online/offline presence for routing.

Kayako's public changelog has been silent since mid-2022 — the radar is showing a stalled product.
◆ Current state
Kayako has not posted a public changelog entry since June 2022. The most recent communication was a CEO apology over a performance incident and a series of link-only release-notes posts pointing to a Help Center article. The visible operational picture is an established customer-support product no longer broadcasting product motion.
◆ Where it's heading
Direction is hard to read from public changelog activity alone, but the trajectory implied by the silence is unmistakable: either the product moved its release communication elsewhere, or development pace slowed enough to stop justifying a regular changelog. Either way, prospects watching only the public surface see no momentum.
◆ Prediction
Without renewed public activity, Kayako will continue to be perceived as legacy in a category where Zendesk, Intercom, and HelpScout are publishing prominently. A customer-facing changelog refresh would be the lowest-effort signal to send, and is the most likely next move if the product is in fact still under active development.
Respond.io
7.5COMMSSUPPORT
Respond.io upgraded its AI Agents to GPT-5.6 and added TikTok Business Messaging for US accounts.
◆ Current state
Respond.io is shipping across three tracks simultaneously: AI Agent improvements (GPT-5.6 model upgrade, pre-publish instruction review), channel expansion (TikTok Business Messaging for US, Microsoft 365/Outlook email), and workflow automation (missed call auto-follow-up, Google Calendar integration). The status persistence fix — keeping agents online as long as the tab is open — addresses a real reliability concern for teams that rely on online/offline presence for routing.
◆ Where it's heading
The product is converging on a model where AI Agents handle routine conversations while human agents handle escalations, with channels increasingly auto-enrolled (missed calls become conversations, calendar events surface in the inbox). The channel expansion pace (TikTok, Microsoft 365, Google Calendar within weeks) suggests a deliberate push to cover every channel a business customer might use.
◆ Prediction
Voice channel integration — handling inbound calls with AI Agents rather than just converting missed calls into follow-ups — would complete the omnichannel picture respond.io is assembling.
