WOW, I didn’t know it was Christmas Day already! Hurrah!! 
There are so many goodies here given us users as presents in the new 4.2 version, that we’re really getting spoiled. The 4.2 version obviously will stand as a really great dt issue – really a monument of the force in FOSS.
Thank you very much to all developers and those providing various supporting actions with manuals, notes, web-pages, packing, translation, QA, answering questions here in forum and what not!

We changed our release dates to Summer and Winter Solstice, so you get it a bit before Christmas now.

Thanks for the release. But I am unable to open Sony ILCE-7RM5 RAW files. I thought it was supported.
An endless thank you to all darktable developers for create this great and addictive piece of software, this release comes with excellent and unique tools for develop our raw files.

Maybe not compressed raws Is that what you tried?? I am just guessing
It is absolutely amazing how every new version of Darktable has me giddy like my kids on Christmas Eve!
This has become a rare occurrence in my life as a jaded software developer. So thank you, for putting the joy back into software!

Thanks to all for this great piece of software
Thanks about the 4.2.0 for everyone involved! Releasing it before Christmas was a nice bonus, since now I have a couple of evenings time to play with the new version before I’ll be away visiting family

Is this automatic? I looked through the settings, but couldn’t find anything.
It should be j in the string of opencl config values and it is currently disabled by default.
ya lossless. Looks like Darktable to does not support lossless compression and has no intention of adding it. I don’t want to loss information by shooting in compressed and I can’t just shoot in uncompressed raw, due to long term storage. Will have to look into converting to TIFF, or just moving to lightroom.
DT relies on rawspeed so if and when this gets supported you will be able to use that. DNG should be fine if you want access to the DT software. I don’t think those compressed formats are straightforward and open source folks wont get the same access to documents for support as Adobe would…
Curious will ART open them??
