This release allows early testing of an alpha version of the new C3 runtime! Please note that this is an early alpha-quality release - expect bugs, issues and missing features. Since it is still in development it is not enabled by default. To use it you'll first need to enable experimental features in Settings, and then a new runtime option will appear in the Advanced section of Project Properties. Since this is a major feature release with many details to note, please see the blog for more information about the current state of the C3 runtime.
We've also included a new demo RPG game "Demonoire". See the linked blog post for more information. You can try it out from the Game Demos category in the Start Page.
In addition to all that, we've also got a big batch of other additions, changes and fixes. In particular the Animations Editor has a series of improvements, which you can see detailed in the change log.
Please note one significant issue that ought to be fixed in this release: a serious bug in the latest Safari 11.1 update causes Construct 3 to get stuck building or rendering spritesheets. This can cause images in the Layout View to fail to appear correctly, and preview and export can hang at the progress bar. We've already reported the issue to Apple who are currently working on it, but since Safari releases can come months apart, we've implemented a workaround for this release. So until the next stable release, if you run in to issues with Safari, please try using the beta channel instead.
This is a huge release and the launch of testing for the C3 runtime is a major milestone in the development of Construct. We're excited to get the new engine in to your hands! However we also ask for your patience, as it is a huge project and will take some time yet to mature, with a complete featureset, fixed bugs, full compatibility, and so on. If you run in to issues with it please file a bug report, mention that you're using the C3 runtime, and be sure to follow all the bug report guidelines to ensure we have the best chance of resolving the issue. With your co-operation we can make sure the C3 runtime is robust, feature-complete and 100% compatible with the C2 runtime in advance of fully launching it as enabled by default.
