Calendly is quietly becoming a CRM with a payment terminal and an agent-facing API.
Scheduling is no longer where Calendly's releases land. The last two months added contact profiles with custom fields, lists and note reminders; multi-session Meeting Packages sold with upfront payment; standalone Payment Links that work without a booking at all; and a Claude connector that exposes event types, availability and booking to an assistant. Each of these sits beside the calendar rather than inside it.
Chanty's feed is an HR statistics content mill, not a product changelog
Every entry in the window is a marketing article — referral, theft and satisfaction statistics roundups, plus a run of competitor-alternatives listicles published in a single batch. Nothing here describes a change to the messaging product itself.

Each of these sits beside the calendar rather than inside it.
Two expansions are running at once. Calendly is building the lightweight relationship layer its users previously kept in a CRM — fields, lists, follow-up nudges — and it is moving from collecting payment for a booking to collecting payment as its own action. The Claude connector points the other way: the booking flow becomes something an agent drives while the human stays in a conversation.
The contact object is the piece everything else can hang from, so expect follow-up automation and segmentation to build on lists and custom fields next, and payments to keep detaching from the booking flow. Whether the agent connector stays a convenience or becomes the primary interface is not something these entries can settle.

The publishing effort is going into search-driven HR and collaboration content aimed at buyers comparing team chat tools, with the alternatives posts targeting Slack, Yammer, Jive, Google Chat and Skype by name. Product direction cannot be read from this feed at all.
Expect more statistics roundups and comparison listicles; the feed gives no basis for predicting anything about the product.
