Slack prioritized security and stability across seven releases in the last 90 days, shipping minor security improvements in four versions and backend maintenance in the others. The team rolled out incremental security patches throughout February and March before moving to infrastructure work in early April, suggesting preparation for larger feature work ahead.
March focused on security hardening across three releases. The team shipped two minor security improvements early in the month, then followed with a recommended security update mid-March that addressed vulnerabilities requiring prompt adoption.
