I'm happy to announce the release of ReactJS.NET 2.4! The main change in this release is upgrading the ASP.NET 5 (or "ASP.NET Core" as it's now called) integration from RC1 to RC2. Some other minor changes are also included. Changes in this release:

 - [#271](https://github.com/reactjs/React.NET/pull/271) - Upgrade to ASP.NET Core RC2. *Thanks to [Shiki Byakko](https://github.com/ShikiGami)*.
 - [#254](https://github.com/reactjs/React.NET/pull/254) - Allow JavaScript engines to be bypassed entirely. *Thanks to [Dustin Masters](https://www.dustinsoftware.com/)*.
 - [#266](https://github.com/reactjs/React.NET/pull/266) - Allow customisation of file name extension for Babel transpilation. *Thanks to [Andrew Ovens](http://andrewovens.com/)*.
 - [#270](https://github.com/reactjs/React.NET/pull/270) - Always return JS engine to pool after component render. *Thanks to [Dustin Masters](https://www.dustinsoftware.com/)*.
 - [#253](https://github.com/reactjs/React.NET/issues/253) - Fix handling of relative paths in OWIN.
 - Temporarily disable Chakra Edge JS engine, as it's throwing "Attempted to read or write protected memory" errors. Chakra MSIE is still enabled, although V8 is the recommended engine for ReactJS.NET.
 - [#226](https://github.com/reactjs/React.NET/pull/226) - Serialize props when they're set, rather than every time the component render code is called. This ensures that the props are only serialized once rather than twice.

Have fun, and as always, please feel free to send feedback or bug reports
[on GitHub](https://github.com/reactjs/React.NET).
