ISPConfig 3.3 Released
This version introduces numerous improvements, including system load graphs on the Dashboard and in the Monitor Module, PostgreSQL database support for websites, enhancements to Let's Encrypt SSL certificates, PHP-CLI versions that match the website's PHP versions, and more.
Update 2025-04-26: We updated the released version today to 3.0.3p1 to fix an issue that clients were unable to create a new database due to limit exceeded messages.
What’s new in ISPConfig 3.3?
Dashboard & Monitor Module Graphs
We’re introducing real-time visualization of your server’s performance. With ISPConfig 3.3, you can view your system load, memory usage, and network data transfer as easy-to-understand graphs. These will be displayed on the dashboard and within the monitor module, giving you insight into resource usage at a glance.
PostgreSQL Database Support
Beyond MySQL and MariaDB, you’ll be able to use PostgreSQL databases for websites in ISPConfig. This highly requested feature provides greater flexibility, enabling you to host web applications that rely on PostgreSQL.
Let’s Encrypt Enhancements
Auto Cleanup of Certificates: Old certificates will be automatically removed, reducing clutter and keeping your certificate storage organized.
ECC Certificates: In addition to RSA certificates, Let’s Encrypt in ISPConfig 3.3 will support ECC (Elliptic Curve Cryptography) certificates for more modern and efficient encryption.
Shared PHP Version for Shell Users
When you define the PHP version for a website, the same version will now apply to any shell users associated with that website. This streamlines your workflow, ensuring consistent environments for your development and deployment processes.
Plugin & Extension Installer
We’re making it easier than ever to expand ISPConfig’s functionality. With the ISPConfig Plugin/Extension Installer, you will be able to discover and install new extensions without leaving the control panel (System > Extension Installer and via ispc extensions command). This means a smoother and more centralized management experience.
Extension repository: https://repo.ispconfig.com/
More extensions, such as the ISPConfig WordPress Manager and ISPConfig Billing Module will be available in the next few days.
Automatic Nightly Backups
Your ISPConfig configuration and database will benefit from an automatic nightly backup process. These backups will keep your environment secure and recoverable, minimizing downtime in case of data loss or system issues.
sha2_caching_password for MySQL
For users running MySQL 8 or later, we are adding support for sha2_caching_password. This ensures you’re taking advantage of the latest authentication methods, offering improved security for your databases.
