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.
Small patches every few weeks, and a salon console that keeps moving to mobile.
Salon Booking System is a WordPress appointment plugin releasing patch versions every few weeks, each a short list of fixes with one or two additions. The 10.30 line carries the substance: a mobile web app interface in March, drag-to-resize booking duration and WhatsApp quick-links in February, two-way Google Calendar sync improvements in April, and a forecasted-bookings screen with in-form service search in June. July's release is purely corrective — Revenue Guard report endpoints returning HTTP 500, and an empty time-slot grid on the booking form.

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.
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.
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.

Two directions run through the patch stream. One is the salon owner's console moving to mobile, with a progressive web app calendar that supports drag-resize, walk-in badges and its own diagnostics. The other is closing revenue leaks: no-show handling, Revenue Guard reporting, a Stripe payment status refresh, discount exclusion rules. Security patches appear inside several of these releases with no announcement of their own, which matters to anyone tracking WordPress plugin risk.
Revenue Guard now has its own reporting endpoints and needed a fix within weeks of appearing, so it is under active development and likely to grow past reporting cards. The changelog format offers no roadmap beyond that.
