The MUSE Hubble Deep Field Survey is the deepest spectroscopic survey ever performed over the entire Ultra Deep Field (UDF) area. It provides ~1700 spectroscopic redshifts, an order of magnitude more compared to the data that has been accumulated on the UDF over the past decade, up to AB 30 in magniude and 6.7 in redshift. The depth and high quality of the data enables new and detailed studies of the physical properties of the galaxy population and their environments over a large redshift range. In this talk I will show in advance of publication a number of important results achieved by the survey on a diversity of topics: investigation of bias in photometric redshift, spatially resolved stellar kinematics at z~1, properties of CIII emitters, FeII emission in stellar forming galaxies, Lya luminosity function and its impact for reionization, Lya extreme EW objects undetected in UDF, Lya extended halos, evolution of the galaxy major merger rate with redshift, etc.
