+### Improved troubleshooting
+
+We've enhanced our troubleshooting capabilities to provide you with better insights and more efficient problem-solving tools:
+
+#### Enhanced PMM Server logs
+
+The default number of log lines for each log file returned by `httsp://<pmm-server>/logs.zip` endpoint has been increased from 1,000 to 50,000.
+
+Additionally, the endpoint now includes a customizable line-count parameter in the download URL, allowing you to specify a custom number of log lines or opt for unlimited log size. For more information, see the [API documentation](https://percona-pmm.readme.io/reference/logs).
+
+#### Streamlined Kubernetes diagnostics 
+
+New PMM client docker images now include essential troubleshooting tools:
+
+- `tar` enables easier file transfer in and out of containers using the `kubectl cp` command.
+- `curl` allows direct checking of exporters to verify their proper functioning.
+
 ### Official ARM support for PMM Client
 With the growing adoption of ARM in data centers and cloud environments, we are excited to announce official support for ARM architecture in PMM Clients. This enables you to seamlessly monitor ARM-based infrastructure, including popular cloud instances and emerging ARM-powered servers.
