42 Upgrade notes for 7.0.31

Minimum Logback library version

The minimum Logback library version has been raised from 1.5.16 to 1.5.25.

TLS verification for HTTP-based templates and media types

Templates and media types that connect to HTTPS endpoints now verify the endpoint's TLS certificate by default.

This change affects all cloud and API monitoring templates (e.g., Cloudflare by HTTP, Kubernetes nodes by HTTP) and all webhook media types (e.g., Slack, Jira, Telegram). You can change this behavior with the new {$HTTP.TLS.VERIFY} user macro that has been added to these templates and media types. For details, see the README file of each HTTP template or webhook.

When you upgrade Zabbix, templates and media types are not upgraded automatically. This avoids overwriting any custom changes you have made. To upgrade or add templates and media types manually, see the template upgrade instructions.
