Now, this process can be centralized in Flexisip Account Manager, which handles forwarding notifications to native push platforms.<\/p>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 100%;\"><strong>\u2705 Benefits:<\/strong><\/p>\n<ul>\n<li>Simplified on-premise deployment of the Linphone suite<\/li>\n<li>Centralized notification management via a FlexiAPI server instance<\/li>\n<li>Reduced constraints related to push certificates<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Additionally, Flexisip now supports the use of an <strong>outbound HTTP(S) proxy<\/strong> for push notifications, making deployments easier in enterprise environments where all external HTTP(S) traffic must go through a proxy.<\/p>\n<h3>Improved service availability<\/h3>\n<p>This version introduces <strong>new<\/strong> <strong>automatic<\/strong> <strong>process freeze detection mechanisms<\/strong>. In case of anomalies, Flexisip can <strong>detect blocking<\/strong> situations and <strong>automatically<\/strong> <strong>restart affected services<\/strong>, reducing downtime and improving continuity.<\/p>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 100%;\"><strong>\u2705 Benefits:<\/strong><\/p>\n<ul>\n<li>Improved platform resilience<\/li>\n<li>Reduced service interruptions<\/li>\n<li>Higher production availability<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>New administration tools<\/h3>\n<p>Administrators now have access to new commands to view and invalidate the user authentication cache.
