In this release we've ported the User Media plugin to the C3 runtime. However over time the plugin had become a bit of a mess - it's had a few extra features chucked in which aren't all directly related to getting camera/microphone input. So in the C3 runtime we've split the User Media plugin in to four plugins: User Media (keeping the existing plugin, but removing all features except camera and microphone input), Game Recorder (based on the canvas recording feature), Speech Synthesis and Speech Recognition. Game Recorder also has the new ability to also record audio with the video, providing a useful new way to record clips for trailers and such.
Note that you can switch existing projects using the User Media plugin to the C3 runtime, but in that case all features relating to canvas recording, speech synthesis or speech recognition will stop working until you replace them with the new plugins. Also note these new plugins are only available in the C3 runtime.
This build also adds support for the C3 runtime in the addon SDK. This means addon developers will now be able to get started on porting any third-party addons for the C3 runtime. We need to update our SDK documentation to properly cover the new C3 runtime code, which we plan to do soon.
Finally there are some updates for Cordova support which should help resolve some issues, and a batch of bug fixes as usual. We're keen to get a new stable release out shortly since a bug in the latest Safari update is preventing the current stable release from working. We've worked around it but the fix is currently only available in beta releases. Ideally we can bring the fix to the stable channel shortly to ensure Construct 3 works correctly for all Safari users. So if you run in to any important issues please make sure they're reported and as ever please follow all the guidelines to ensure we can help!
