Wowza Streaming Engine 4.3 is out

Just saw today that Wowza Streaming Engine 4.3 is out. Quick summary of the main changes are:

• The REST API that has been around for a while is now opened up to everyone and got the version name 1.0 (which is v2 for some reason in the actual URLs..)
• A new API has been added that allows extracting clips from live streams. See the corresponding API comments here 
• A new stream target option appears on the Engine Manager interface to deliver output directly to their Wowza Streaming Cloud. (Version 4.2 previously made similarly easy for delivering to YouTube)
• Specific and upgraded JVC camcorders can deliver RTMP stream now directly to Wowza (to be honest I am not sure about this, I thought that this should not be a change in Wowza itself, only the camcorder firmware)
• MPEG-DASH Example Player updated and is based on Google Shaka Player
• New Java API methods to control purging of Media Cache Elements (see MediaCache here)
• HEVC (High Efficiency Video Coding)/H.265 Video over Apple HLS preview available in the Transcoder

The detailed list of changes can be found here, one point that was interesting to me is:

• Updated genkey.bat to work with updated environment variables created with Wowza Streaming Engine 4.2 installers

This was an annoying bug that I reported when I tried installing 4.2 on a non-English Windows box. The script that was setting file permissions assumed English default group names and was unable to handle the lack of these groups, causing the installer to throw an error and delete everything. The support was quick and helpful and the fix came out in the next minor release.
