Xb2.NET v4.0 with support for IPv6 & TLS 1.3 is now available for download.
NOTE: In order to support IPv6 we were forced to drop support for Windows
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.
* Add 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 enhancements to prevent certain denial of service
(DoS) hacks on the HTTP server.
This release is available free of charge to all users with valid support.
If you are a licensed Xb2.NET user but your support period has expired, you
will need to purchase an upgrade. All upgrades include 12 months no-charge
support and software updates.

Xb2.NET is an essential tool for developing cloud and secure Internet
applications. It provides support for low-level socket communications as
well as interfaces for WebSocket, Telnet, FTP, HTTP, SSL/TLS, XML, JSON
and SOAP. With Xb2.NET, it is possible to develop 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.
