Passenger 6.1.1 application server has been released with support for Ubuntu 25.10, improved Ruby 4 compatibility, and a critical bug fix for Nginx uploads. The bug affected requests with buffering disabled where request bodies larger than client_body_buffer_size would become corrupted. The release also upgrades Boost to 1.90, updates Nginx to 1.28.0, and includes numerous library updates in precompiled binaries including OpenSSL 3.6.0, curl 8.17.0, and Ruby versions up to 3.4.8.
