Plain
Plain built an autonomous support agent, and has now built the controls to trust it.
A side-by-side editorial comparison of Kayako and Twilio — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Twilio is retiring its old serverless runtime while pushing consent and deliverability control into APIs.
The changelog reads as a platform in consolidation. Functions Classic is being retired with an automatic migration, the REST API certificate chain is being rotated, and older SendGrid behaviours are being trimmed. Alongside that, the messaging and email surfaces keep gaining programmatic control that used to be manual or impossible: bulk WhatsApp templating with cross-channel fallback, dedicated IPs with managed warm-up for Twilio Email, and a Consent Management API that can now clear network-level toll-free opt-outs.

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.
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.

Twilio is collapsing parallel generations of the same product - two Functions runtimes, SendGrid-era email versus Twilio Email - onto one platform, and simultaneously turning operational levers into API surface. Compliance is where that shows most clearly: consent, branded calling, and registration feedback are all becoming things you configure programmatically rather than things you file a ticket about. The deprecation notices and the certificate rotation share an audience of customers running old integrations, and Twilio is spending its changelog budget telling them what breaks and when.
Expect the migration cadence to continue through the September and October Functions cutover with follow-up notices on edge cases, and expect more of the compliance surface - the new TFV and A2P error codes already scheduled for September 15 - to land as API-readable signals rather than console-only state.
