P: Support for HEIC file format (Windows)

I already did subscribe to the group 🙂
The master files *have* to be kept, else it’s a fake support.

It's a shame to work on such small feature for such a long time. You should consider to hire more qualified developers.

In this very thread an Adobe representative has already said that they "are working on the same.[HEIC support]. We will update you soon."

Adobe said it was OK to let people know they are working on adding HEIC support throughout the Lightroom ecosystem... But as a rule, the company (as with most software developers) doesn't give specific future release dates, and never has. 

ProDesignTools –  Are you officially representing Adobe and speaking on their behalf on this matter? 

I'm quite sure that there are a myriad of items that the Lightroom team has been working on and are eventually 'coming to Lightroom' ... the question is when is this capability arriving?

If you find Jay's 'torrent of posting' troublesome ... simply don't read them ... That's what I do when I see topics or comments that are of no interest to me. I try not to speak for 'some of us' ... I prefer to allow others to speak for themselves.

I could not agree more.  Skylum's Luminar deals with the HEIC format but does not keep the master images in a operate location from the catalog - or so I was told by Skylum's support.  The is a real challenge if you use a laptop in the field and then come home and connect to a RAID to store the images permanently.  Two things you can do 1) Vote at the top of the page (important) 2)Consider joining this FB group: https://www.facebook.com/groups/255453151688912/requests/

Photo/video management has become a joke since I now have to store the HEVC videos and portrait HEIC pictures (in order not to lose the depth information on portrait photos) in separate folders while I integrate JPEG files in Lightroom (converted from the HEIC files for non-portrait photos). It's a hassle and a shame.

Sure, it is supposed to save file size relative to JPEG. It's still lossy, and if non-destructive editing is the "core" reason, shooting lossless DNG is the logical choice.

That may be true.  However: 
High Efficiency Image File Format (HEIF, often pronounced heef)[1][2][3][4] is a file formatfor individual images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is defined by MPEG-H Part 12 (ISO/IEC 23008-12). The MPEG group claims that twice as much information can be stored in HEIF image as a JPEG one of the same size, even in better quality.

HEIC is still a lossy format, isn't it, and LR edits to JPEGs are non-destructive. Shooting DNG with the LR Mobile camera offers you a lossless option. You may find that you get more out of your money by experimenting with it.
