Calendly now bills, invoices, and emails — the scheduling link is just the entry point.
Calendly has spent recent releases assembling a contact layer and a billing layer around the booking it started from. Contacts can be imported and exported by CSV, created automatically from Typeform and Google Forms submissions, and now emailed directly through a connected account. On the money side, invoices can be created, sent and tracked with collection through Stripe, and the PayPal integration has widened to Venmo and more card options.
Pixelfed 0.15.2 ships the PHP RCE patches and turns cached timelines on for everyone.
Pixelfed v0.15.2 is an urgent security update: Docker images pick up the patched PHP for this month's two remote code execution CVEs and are rebuilt with updated CAs after the eMudhra compromise. It also makes cached timelines the default, removing two experimental flags, and bundles timeline and WebFinger fixes.

Calendly is assembling the pieces a solo professional would otherwise buy separately — a contact record, ways to populate it, a way to bill for time, and a channel to follow up. The form-sync work is the intake end of that: contacts now arrive from sources that have nothing to do with a booking, which is the same boundary invoicing crossed on the billing side when it let money be collected for work the calendar never touched. Each release is small and none carries the shift on its own, but the set is close to complete.
Segmentation and templating are the obvious follow-on to outbound email, since personalized sending without lists to send to is only half a workflow. Whether invoicing gains recurring billing remains the open question these entries do not answer.

Pixelfed has moved quickly through 0.14.5 and 0.15 with federation fixes and new APIs, and now an upstream security patch. The notes say heavy refactoring will continue toward a Nuxt-based web UI, so the near term is more churn in the front end.
Expect more 0.15.x patches for regressions from the refactor, with the Nuxt web UI as the next visible milestone.
