 - Copy button shortkey was added at the top-right of code-blocks.
 - Pragma directive that reports warnings as errors on MSVC was fixed. 
 - Command line argument ``--hpx:loopback_network`` was added to facilitie debugging with networks.
+- We added an HPX-SYCL integration, allowing users to obtain HPX futures for SYCL events. This effectively enables the 
+  integration of arbitrary asynchronous SYCL operations into the HPX task graph. Bolted on top of this integration,
+  we further added an HPX-SYCL executor for ease of use.
