What's New in When'd I

2.3.0

September 14, 2026

The Catalog has a new Calendar tab: switch between a month grid and a year of dots to see what you did each day. The A–Z tab is gone. Searching in Photos now filters the photo and memo feed itself, and you can hide memos to see photos only. Polished details across Photos and Calendar, including search alignment and feed spacing.
