v3.5.1

v3.5.1

Date: 2026-07-28
Previous release: v3.5.0

Summary

Adds --filter-multi flag to deployments create for targeting multiple
devices via inventory filters.

Highlights

• --filter-multi flag: Target all devices matching inventory filters
  instead of requiring exactly one match. Useful for deploying to device
  classes (e.g. --filter-multi "device_type=gateway").
• Confirmation dialog: Shows matched device count before creating
  deployment. Use --yes to skip for automation.

Example Usage

# Deploy to all gateways
mender-cli deployments create --release v2.0 --filter-multi "device_type=gateway"

# Combine multiple filters (AND logic)
mender-cli deployments create --release v2.0 \
    --filter-multi "device_type=gateway" \
    --filter-multi "tags/environment=production"

# Skip confirmation for automation
mender-cli deployments create --release v2.0 --filter-multi "device_type=gateway" --yes

Notes

• Existing --filter unchanged: The -f/--filter flag still requires
  exactly one matching device, showing matched IDs in the error message when
  multiple devices match.
• Mutually exclusive: --filter-multi cannot be combined with --device,
  -f/--filter, --group, or --all.

Upgrading

• No breaking changes. The new --filter-multi flag is purely additive.
