General Purpose Coarse-Grained Force Field 
Check out a nice paper from Lucendo et al, in PNAS, showing how TM helix dimerization plays a role in apoptosis. Featuring the Martini 3 beta release, corroborated by atomistic simulations and experimental data.
Working with large systems containing multiple bilayers or other dynamic macroscopic objects? Check out the new MDVoxelSegmentation tool.
Cool paper on the phase behavior of liquid crystals, demonstrating the transferability of Martini, outperforming bottom up models:

Be aware of using proper mdp settings when simulating cholesterol, as it might cause artificial phase separation if you don't, according to Javanainen et al: arXiv:2009.07767
Martini is not only suitable to simulate biomolecular processes, but also increasingly to study material properties. Check the latest paper from our group on resolving the impact of polar side chains on electronic and structural properties of donor-acceptor (DA) interfaces of organic semiconductors:
