Mbin Blog Updates

We are excited to announce the latest release of Mbin; v1.7.3! It's a big patch release once again. This version is focused on bug fixes and improvements rather than new features. Notable improvements in random order are:

• Improved PHP (max_children), Nginx (improved logging using map, upstream block for Mercure and open_file_cache) and PostgreSQL documentation (adding commit_delay config option and better defaults).
• Better RabbitMQ messenger defaults
• Fixed security Symfony audit & update all Symfony packages
• Fixed self-delivery looping
• Improved delivery handler by not rolling back InvalidApPostException exceptions
• Fixed private comments retrieval via API
• Fixed dead instance query (by allowing lastSuccessfulDeliver to be NULL)

• Improved federation page
• New/improved npm audit and composer audit checks in GitHub Actions workflow
