What’s New in Asana & Trello: May 2025 Release Notes Digest
By Sima Team | June 7, 2025
TL;DR – Asana shipped bulk manual rule triggers and Inbox notifications inside Microsoft Teams, while Trello rolled out a redesigned Card Back, brand-new Planner calendar, and an AI-powered Inbox. These quality-of-life updates can shave 2–4 hours/week off task triage at most agencies.
Why Agencies Should Care
- Less context-switching. With Asana updates landing directly in Teams chats and Trello adding an AI Inbox, your PMs can process tasks without hopping tools.
- Faster bulk edits. Asana’s multi-task manual triggers let you run automations across dozens of tickets in one click—perfect for sprint grooming.
- Visual clarity for clients. Trello’s new Card Back surfaces key attachments and power-ups up front, reducing “where’s the file?” Slack pings.
