I came across this post on reddit with some interesting comments from @MrChromebox (assuming the same user) about the v4 release and what may be in the pipeline for the v5 slated to come our this summer.
USB-C power cable. yes please! It would appear that this could be a possible feature introduced allowing any compatible power-brick to be used. It raised a lot of interest on the reddit posts too.
LED power next to charging cable socket - this was a featured I requested earlier and I am not sure if it has been implemented yet on the v4.
Dual dimm RAM slots - the reddit discussion points to a new MB being designed which will have dual dimm slots.
Flush USB sockets - as I initially reported on my feedback/review of my Librem 15v3, maybe this is already fixed on v4?
Arrow keys with reliefs - this would allow to easily access the right/left arrow key without looking down to the keyboard…I keep hitting the # 1 key on the numerical keys when trying to kind the right arrow key.
Functional home/end keys - currently I am unable to have the home/end navigation on a text line in an editor. I reported this here earlier, and never found a solution to this problem.
Better battery management ? I faced some issues with my battery management (especially at low capacity) and finally have to follow this advice to manually ensure longevity. My first battery only lasted 1 year. However, from my past experience with macbooks, I have been able to have a relatively care-free attitude towards the charging (the computer would hibernate when low on juice) and the battery lasted 3 years before I had to change it. It is really difficult to achieve this with a librem?
