Thank you @Gwyneth! Although I want the 4.4 version that is used under 7.0 and not the beta version of 7.0 or a previous 6.x. It seems that a new 7.0.1 was just published and the sources for that one are missing as well.
Hi, I can see that this announcement showed up on the activity page about 20h: Synology Open Source Project released /Synology NAS GPL Source/41890branch/apollolake-source/linux-4.4.x.txz But when trying to download the file it does not work (it says the file is no there). If I browse through the files I cannot see under "NAS GPL Source" any folder named "41890branch". Can you please check? Thanks Mircea
