What's new

Blazor Server Support

Sitefinity Cloud now supports Blazor Server applications. This enables real-time interactive web experiences using Blazor Server-side rendering. SignalR session affinity is automatically configured to ensure WebSocket connections are routed consistently, providing a seamless experience without additional configuration.

What's improved

  • Improved CDN cache purge performance and reliability by rewriting the purge pipeline to process invalidations more efficiently, reducing purge latency for large-scale operations.
  • Fixed an issue where expired content items were not fully processed during CDN cache invalidation, which could leave stale content served to visitors.
  • Upgraded Redis to the latest version for improved stability.
  • Fixed an issue with applying CI/CD pipeline variable group settings for .NET Renderer where the minimum log level was not correctly configured.
  • Fixed an issue where the SiteSync feature could exceed the daily log quota, causing log data to become unavailable. Log retention and quota settings have been adjusted.
  • Fixed an issue with blank trial project provisioning.
