About Fellow
Fellow's public changelog has been silent since 2021 — no recent direction is observable here.
The visible signal stops in spring 2021. The last few releases were calendar-extension touch-ups: action items appearing directly in the Google Calendar extension, public view-only meeting links for external attendees, and multi-calendar sync within a single Google or Office account. Nothing in this dataset reflects the past several years of Fellow's actual work.
