# What's new in March 2025

Published Mar 11, 2025

## TCP checks generally available

After a successful beta phase, TCP checks are now available across all plan types. Use them to monitor mail servers (IMAPS or SMTP connections), custom TCP services, and firewall rules. TCP checks are fully integrated into Monitoring as Code workflows and available in the CLI starting v4.19.1.

## Checkly CLI 5.0.1

A new major CLI version that requires Node.js 17 or later. It adds alert channel constructs for defining Incident.io, Microsoft Teams, and Telegram alerts as code, and fixes command line reporters to include the degraded status.

## Pulumi provider update

The Checkly Pulumi provider received an overdue update, including `checkly test` and `checkly trigger` retries, which are especially useful in CI workflows. Issues and feature requests go directly in the checkly/pulumi-checkly repo.
