NOTE: In order to support IPv6 we were forced to drop support for Window XP and Server 2003. As a result, Xb2.NET v4.0 will no longer run on these legacy operating systems. At the same time however, we are also making available Xb2.NET v3.8 which only supports IPv4 but will continue to run on Windows XP and Server 2003. If legacy operating system support is not needed, then you are advised to upgrade your applications to v4.0.
Regardless of the operating system, rest assured that both Xb2.NET v3.8 and v4.0 support the latest security and encryption standard - TLS 1.3!
Other highlights of this update:
- New xbEval() function to dynamically compile and run external .PRG scripts. Can now use dynamic scripts in any (desktop or web) application.
- Added support for SHA-3 Secure Hash Algorithm.
- New onSend event handler which is triggered just before HTTP content is transmitted. Added a new WebSocket mirroring sample that shows how to use onSend to mirror the screens of remote clients.
- Some bug fixes and reliability enhancements to prevent certain denial of service (DoS) hacks on the HTTP server.
Xb2.NET is a "must have" tool for developing secure cloud applications. It includes automated integration with Let's Encrypt to get, install & renew SSL/TLS domain certificates at zero cost. The library also provides support for low-level socket communications and interfaces for WebSocket, Telnet, FTP, HTTP, SSL/TLS, XML, JSON and SOAP. With Xb2.NET, it is possible to build a native stand-alone Xbase++ web server that does not rely on any external services.
Released in 2002 and continually enhanced, Xb2.NET has matured into a robust tool that you can safely depend on to build mission critical client and server-side applications.
