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 Plain?

Sidekick got skills and MCP; now Plain is clearing the path to move your history in.

Plain's recent releases built Sidekick from an in-thread helper into an operator that uses workspace skills and connects to any MCP server, with workflows becoming the trigger layer for that agent work. The newest entry moves to the other end of the funnel: custom importers pull past conversations in from any tool, including in-house systems, with no built-in importer required.

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.

Sidekick got skills and MCP; now Plain is clearing the path to move your history in.

◆ Current state

Plain's recent releases built Sidekick from an in-thread helper into an operator that uses workspace skills and connects to any MCP server, with workflows becoming the trigger layer for that agent work. The newest entry moves to the other end of the funnel: custom importers pull past conversations in from any tool, including in-house systems, with no built-in importer required.

◆ Where it's heading

Capability, then autonomy, then extensibility, and now onboarding. Removing the importer dependency means adoption stops being capped by Plain's connector roadmap, the same way the agent's ceiling stopped being its integration roadmap. The pattern across both is Plain declining to sit as the bottleneck between a customer's existing systems and its own product.

◆ Prediction

Expect the importer work to be followed by tooling that puts migrated history to use - Sidekick reading imported conversations for context is the obvious next step given the skills and MCP groundwork already shipped.
