New Features

Networking

• Engine: Add the maxConcurrentRequestsPerHost setting. It limits how many images, fonts and videos the engine downloads at the same time from one host. Use it for a server that rejects too many requests at once. A further download waits until one of them ends. Each engine counts its own downloads, and an export copies the setting into its export engine. The Renderer takes it as --max-concurrent-requests-per-host. The default is 0, which sets no limit, as before. In the browser and in @cesdk/node, a video that streams in parts counts only until its first parts load.

Bug Fixes

Engine

• Video fills now keep showing their frames in playback and in a video export when memory runs low. Before, the engine released a video that still played, and its fill stayed blank or frozen for seconds while the file loaded again.
