New Stable is out: 2025.18.

High-level changes include:

• A vulnerability fix in Aphlict - Blog Post: DoS attack against Aphlict (Action Required on your part.)
• Phorge now requires PHP version 7.2.25 or later. There's a known problem with 8.4 though (T15989).
• There's actually a DB migration is this time.
• Some very-old CSS rules were removed
• Better support for large screens and for Calendar imports
