[FFmpeg-user] Use of -hls_flags iframes_only results in incorrect EXT-X-VERSION value

Hello,
I'm trying to generate Apple mediastreamvalidator compliant HLS using
ffmpeg and have very nearly achieved that.
The only remaining problem is that use of " -hls_flags iframes_only"
correctly adds the #EXT-X-I-FRAMES-ONLY tag to my trickplay m3u8 but it
doesn't increment the #EXT-X-VERSION value from 3 to 4.
The validator then complains as follows:
--------------------------------------------------------------------------------
MUST fix issues
--------------------------------------------------------------------------------
Error: incorrect version number for feature
--> Detail: Line: (null)
--> Source: output_TrickPlay_Video_8bit.m3u8
If I manually edit the file and change the version value to 4, validation
is successful.
I have upgraded ffmpeg to the latest version but the problem remains.
Is there a way for me to force #EXT-X-VERSION:4 ?
Here is my command and the console output:
