Microsoft provided a new Redstone build to testers today @ 10 AM PT.
Today, we are releasing Windows 10 Insider Preview Build 17623 (RS5)
to Windows Insiders who have opted into Skip Ahead.
This one also includes, as does the latest RS4 build:Introducing High Efficiency Image File Format (HEIF) in Windows 10
The High Efficiency Image File Format (HEIF)
has arrived for Windows 10 and the Photos app! HEIF is an image container that leverages modern codecs like HEVC to improve quality, compression, and capabilities compared to earlier formats like JPEG, GIF, and PNG. In addition to traditional single images, HEIF supports encoding image sequences, image collections, auxiliary images like alpha or depth maps, live images & video, audio, and HDR for greater contrast.
