Enhancements and New Additions

Following are some enhancements made in this release:

  1. NET Core SignalR backplane
  2. NCache SignalR backplane for ASP.NET Core applications is provided.

  3. Support for Internet Explorer 11
  4. Web management can now be done from Internet Explorer 11 (latest release) but its recommended to use Microsoft Edge, Chrome, Firefox or Opera.

  5. Dynamically generated installation keys
  6. Installation keys for all editions of NCache are now dynamically generated at the time of download. This means that every customer gets a unique installation key.

  7. Only .NET based cache servers in Professional and Open Source
  8. Cache servers in Professional and Open Source editions are only .NET based. Clients are available for both .NET and .NET Core. Cache servers can't be installed on Linux for these two editions.

  9. Limited features in Open Source and Professional editions
  10. Open source and Professional editions have gone back to Alachisoft's original strategy where we had a limited number of features in both Open Source and Professional editions.
