It seems like forums and youtube are the most useful resources for information on eurorack modules and discovering artists and releases.
These forums are indispensable:
Muffwiggler (https://www.muffwiggler.com/forum/viewforum.php?f=16&sid=f34e6a2114a226bed010bbce6366b4d1)
Gearslutz (https://www.gearslutz.com/board/modular-mania-all-things-eurorack-and-modular-synths-effects/)
These youtube channels are essential:
Divkid - the monk of modular, Ben is the go-to source for everything modular.
MylarMelodies - great tutorials, recent focus on playing live, Host of "Why We Bleep".
Learning Modular - The best tutorials!
Future Music Magazine
Synth DIY Guy
Color My Sound
Comparative Irrelevance
Modular Podcast - Divkid's other "podcast" (by which i mean that the episodes are best watched as opposed to listened to)
There are several podcasts out there, all of which are worth listening to:
Esoteric Modulation (https://www.esotericmodulation.com)
Podular Modcast (https://podularmodcast.fireside.fm)
Why We Bleep (https://www.whywebleep.com/whywebleep)
SysEx Dumpster (https://www.sysexdumpster.com)
I know that I strayed a bit from your original question; these sites (besides Wiggler and GS) aren't always concerned with what's new or brightest in eurorack. But as someone who just recently began building their first modular synth, these were the places I've found to be the most informative. I have seen a stray module review in Sound On Sound magazine. And although I've yet to read an issue myself, there are two brand new magazines out there:
Waveform Magazine: (https://www.waveformmagazine.com)
Synth and Software (https://synthandsoftware.com)
Artists and releases are your typical underground music affair. You have to put in work to discover what's out there. Pick an artist you like and dig, dig, dig. :-)
